Inheritance diagram for wxGrid:

Detailed Description

wxGrid and its related classes are used for displaying and editing tabular data.

They provide a rich set of features for display, editing, and interacting with a variety of data sources. For simple applications, and to help you get started, wxGrid is the only class you need to refer to directly. It will set up default instances of the other classes and manage them for you. For more complex applications you can derive your own classes for custom grid views, grid data tables, cell editors and renderers. The wxGrid Overview has examples of simple and more complex applications, explains the relationship between the various grid classes and has a summary of the keyboard shortcuts and mouse functions provided by wxGrid.

A wxGridTableBase class holds the actual data to be displayed by a wxGrid class. One or more wxGrid classes may act as a view for one table class. The default table class is called wxGridStringTable and holds an array of strings. An instance of such a class is created by CreateGrid().

wxGridCellRenderer is the abstract base class for rendering contents in a cell. The following renderers are predefined:

The look of a cell can be further defined using wxGridCellAttr. An object of this type may be returned by wxGridTableBase::GetAttr().

wxGridCellEditor is the abstract base class for editing the value of a cell. The following editors are predefined:

Please see wxGridEvent, wxGridSizeEvent, wxGridRangeSelectEvent, and wxGridEditorCreatedEvent for the documentation of all event types you can use with wxGrid.

Sorting support.
wxGrid doesn't provide any support for sorting the data but it does generate events allowing the user code to sort it and supports displaying the sort indicator in the column used for sorting. To use wxGrid sorting support you need to handle wxEVT_GRID_COL_SORT event (and not veto it) and resort the data displayed in the grid. The grid will automatically update the sorting indicator on the column which was clicked. You can also call the functions in this section directly to update the sorting indicator. Once again, they don't do anything with the grid data, it remains your responsibility to actually sort it appropriately.
int	GetSortingColumn () const
	Return the column in which the sorting indicator is currently displayed.
bool	IsSortingBy (int col) const
	Return true if this column is currently used for sorting.
bool	IsSortOrderAscending () const
	Return true if the current sorting order is ascending or false if it is descending.

	Remove any currently shown sorting indicator.
Accessors for component windows.
Return the various child windows of wxGrid. wxGrid is an empty parent window for 4 children representing the column labels window (top), the row labels window (left), the corner window (top left) and the main grid window. It may be necessary to use these individual windows and not the wxGrid window itself if you need to handle events for them (this can be done using wxEvtHandler::Connect() or wxWindow::PushEventHandler()) or do something else requiring the use of the correct window pointer. Notice that you should not, however, change these windows (e.g. reposition them or draw over them) because they are managed by wxGrid itself.

Member Enumeration Documentation

enum wxGrid::CellSpan

Return values for GetCellSize().

Since:: 2.9.1

Enumerator:

CellSpan_Inside	This cell is inside a span covered by another cell.
CellSpan_None	This is a normal, non-spanning cell.
CellSpan_Main	This cell spans several physical wxGrid cells.

enum wxGrid::wxGridRenderStyle

Rendering styles supported by wxGrid::Render() method.

Since:: 2.9.4

Enumerator:

wxGRID_DRAW_COLS_HEADER	Draw grid column header labels.
wxGRID_DRAW_CELL_LINES	Draw grid cell border lines.
wxGRID_DRAW_BOX_RECT	Draw a bounding rectangle around the rendered cell area. Useful where row or column headers are not drawn or where there is multi row or column cell clipping and therefore no cell border at the rendered outer boundary.
wxGRID_DRAW_SELECTION	Draw the grid cell selection highlight if a selection is present. At present the highlight colour drawn depends on whether the grid window loses focus before drawing begins.
wxGRID_DRAW_DEFAULT	The default render style. Includes all except wxGRID_DRAW_SELECTION.

Different selection modes supported by the grid.

Enumerator:

wxGridSelectCells	The default selection mode allowing selection of the individual cells as well as of the entire rows and columns.
wxGridSelectRows	The selection mode allowing the selection of the entire rows only. The user won't be able to select any cells or columns in this mode.
wxGridSelectColumns	The selection mode allowing the selection of the entire columns only. The user won't be able to select any cells or rows in this mode.
wxGridSelectRowsOrColumns	The selection mode allowing the user to select either the entire columns or the entire rows but not individual cells nor blocks. Notice that while this constant is defined as wxGridSelectColumns \| wxGridSelectRows this doesn't mean that all the other combinations are valid -- at least currently they are not. Since: 2.9.1

Constructor & Destructor Documentation

wxGrid::wxGrid ( )

Default constructor.

You must call Create() to really create the grid window and also call CreateGrid() or SetTable() to initialize the grid contents.

wxGrid::wxGrid	(	wxWindow *	parent,
		wxWindowID	id,
		const wxPoint &	pos = `wxDefaultPosition`,
		const wxSize &	size = `wxDefaultSize`,
		long	style = `wxWANTS_CHARS`,
		const wxString &	name = `wxGridNameStr`
	)

Constructor creating the grid window.

You must call either CreateGrid() or SetTable() to initialize the grid contents before using it.

virtual wxGrid::~wxGrid ( ) [virtual]

Destructor.

This will also destroy the associated grid table unless you passed a table object to the grid and specified that the grid should not take ownership of the table (see SetTable()).

Member Function Documentation

bool wxGrid::AppendCols	(	int	numCols = `1`,
		bool	updateLabels = `true`
	)

Appends one or more new columns to the right of the grid.

The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::AppendCols(). See InsertCols() for further information.

Returns:: true on success or false if appending columns failed.

bool wxGrid::AppendRows	(	int	numRows = `1`,
		bool	updateLabels = `true`
	)

Appends one or more new rows to the bottom of the grid.

The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::AppendRows(). See InsertRows() for further information.

Returns:: true on success or false if appending rows failed.

bool wxGrid::AreHorzGridLinesClipped ( ) const

Return true if the horizontal grid lines stop at the last column boundary or false if they continue to the end of the window.

The default is to clip grid lines.

参照:: ClipHorzGridLines(), AreVertGridLinesClipped()

bool wxGrid::AreVertGridLinesClipped ( ) const

Return true if the vertical grid lines stop at the last row boundary or false if they continue to the end of the window.

The default is to clip grid lines.

参照:: ClipVertGridLines(), AreHorzGridLinesClipped()

void wxGrid::AutoSize ( )

Automatically sets the height and width of all rows and columns to fit their contents.

void wxGrid::AutoSizeColLabelSize ( int col )

Automatically adjusts width of the column to fit its label.

void wxGrid::AutoSizeColumn	(	int	col,
		bool	setAsMin = `true`
	)

Automatically sizes the column to fit its contents.

If setAsMin is true the calculated width will also be set as the minimal width for the column.

void wxGrid::AutoSizeColumns ( bool setAsMin = true )

Automatically sizes all columns to fit their contents.

If setAsMin is true the calculated widths will also be set as the minimal widths for the columns.

void wxGrid::AutoSizeRow	(	int	row,
		bool	setAsMin = `true`
	)

Automatically sizes the row to fit its contents.

If setAsMin is true the calculated height will also be set as the minimal height for the row.

void wxGrid::AutoSizeRowLabelSize ( int col )

Automatically adjusts height of the row to fit its label.

void wxGrid::AutoSizeRows ( bool setAsMin = true )

Automatically sizes all rows to fit their contents.

If setAsMin is true the calculated heights will also be set as the minimal heights for the rows.

void wxGrid::BeginBatch ( )

Increments the grid's batch count.

When the count is greater than zero repainting of the grid is suppressed. Each call to BeginBatch must be matched by a later call to EndBatch(). Code that does a lot of grid modification can be enclosed between BeginBatch() and EndBatch() calls to avoid screen flicker. The final EndBatch() call will cause the grid to be repainted.

Notice that you should use wxGridUpdateLocker which ensures that there is always a matching EndBatch() call for this BeginBatch() if possible instead of calling this method directly.

wxRect wxGrid::BlockToDeviceRect	(	const wxGridCellCoords &	topLeft,
		const wxGridCellCoords &	bottomRight
	)		const

Convert grid cell coordinates to grid window pixel coordinates.

This function returns the rectangle that encloses the block of cells limited by topLeft and bottomRight cell in device coords and clipped to the client size of the grid window.

参照:: CellToRect()

bool wxGrid::CanDragCell ( ) const

Return true if the dragging of cells is enabled or false otherwise.

bool wxGrid::CanDragColMove ( ) const

Returns true if columns can be moved by dragging with the mouse.

Columns can be moved by dragging on their labels.

bool wxGrid::CanDragColSize ( int col ) const

Returns true if the given column can be resized by dragging with the mouse.

This function returns true if resizing the columns interactively is globally enabled, i.e. if DisableDragColSize() hadn't been called, and if this column wasn't explicitly marked as non-resizable with DisableColResize().

bool wxGrid::CanDragGridSize ( ) const

Return true if the dragging of grid lines to resize rows and columns is enabled or false otherwise.

bool wxGrid::CanDragRowSize ( int row ) const

Returns true if the given row can be resized by dragging with the mouse.

This is the same as CanDragColSize() but for rows.

This function always returns false for the read-only cells.

bool wxGrid::CanHaveAttributes ( ) const [protected]

Returns true if this grid has support for cell attributes.

The grid supports attributes if it has the associated table which, in turn, has attributes support, i.e. wxGridTableBase::CanHaveAttributes() returns true.

wxRect wxGrid::CellToRect	(	int	row,
		int	col
	)		const

Return the rectangle corresponding to the grid cell's size and position in logical coordinates.

参照:: BlockToDeviceRect()

wxRect wxGrid::CellToRect ( const wxGridCellCoords & coords ) const

Return the rectangle corresponding to the grid cell's size and position in logical coordinates.

参照:: BlockToDeviceRect()

void wxGrid::ClearGrid ( )

Clears all data in the underlying grid table and repaints the grid.

The table is not deleted by this function. If you are using a derived table class then you need to override wxGridTableBase::Clear() for this function to have any effect.

void wxGrid::ClearSelection ( )

Deselects all cells that are currently selected.

void wxGrid::ClipHorzGridLines ( bool clip )

Change whether the horizontal grid lines are clipped by the end of the last column.

By default the grid lines are not drawn beyond the end of the last column but after calling this function with clip set to false they will be drawn across the entire grid window.

参照:: AreHorzGridLinesClipped(), ClipVertGridLines()

void wxGrid::ClipVertGridLines ( bool clip )

Change whether the vertical grid lines are clipped by the end of the last row.

By default the grid lines are not drawn beyond the end of the last row but after calling this function with clip set to false they will be drawn across the entire grid window.

参照:: AreVertGridLinesClipped(), ClipHorzGridLines()

bool wxGrid::Create	(	wxWindow *	parent,
		wxWindowID	id,
		const wxPoint &	pos = `wxDefaultPosition`,
		const wxSize &	size = `wxDefaultSize`,
		long	style = `wxWANTS_CHARS`,
		const wxString &	name = `wxGridNameStr`
	)

Creates the grid window for an object initialized using the default constructor.

You must call either CreateGrid() or SetTable() to initialize the grid contents before using it.

Reimplemented from wxScrolled< T >.

bool wxGrid::CreateGrid	(	int	numRows,
		int	numCols,
		wxGridSelectionModes	selmode = `wxGridSelectCells`
	)

Creates a grid with the specified initial number of rows and columns.

Call this directly after the grid constructor. When you use this function wxGrid will create and manage a simple table of string values for you. All of the grid data will be stored in memory.

For applications with more complex data types or relationships, or for dealing with very large datasets, you should derive your own grid table class and pass a table object to the grid with SetTable().

bool wxGrid::DeleteCols	(	int	pos = `0`,
		int	numCols = `1`,
		bool	updateLabels = `true`
	)

Deletes one or more columns from a grid starting at the specified position.

The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::DeleteCols(). See InsertCols() for further information.

Returns:: true on success or false if deleting columns failed.

bool wxGrid::DeleteRows	(	int	pos = `0`,
		int	numRows = `1`,
		bool	updateLabels = `true`
	)

Deletes one or more rows from a grid starting at the specified position.

The updateLabels argument is not used at present. If you are using a derived grid table class you will need to override wxGridTableBase::DeleteRows(). See InsertRows() for further information.

Returns:: true on success or false if appending rows failed.

void wxGrid::DisableCellEditControl ( )

Disables in-place editing of grid cells.

Equivalent to calling EnableCellEditControl(false).

void wxGrid::DisableColResize ( int col )

Disable interactive resizing of the specified column.

This method allows to disable resizing of an individual column in a grid where the columns are otherwise resizable (which is the case by default).

Notice that currently there is no way to make some columns resizable in a grid where columns can't be resized by default as there doesn't seem to be any need for this in practice. There is also no way to make the column marked as fixed using this method resizable again because it is supposed that fixed columns are used for static parts of the grid and so should remain fixed during the entire grid lifetime.

Also notice that disabling interactive column resizing will not prevent the program from changing the column size.

参照:: EnableDragColSize()

void wxGrid::DisableDragColMove ( )

Disables column moving by dragging with the mouse.

Equivalent to passing false to EnableDragColMove().

void wxGrid::DisableDragColSize ( )

Disables column sizing by dragging with the mouse.

Equivalent to passing false to EnableDragColSize().

void wxGrid::DisableDragGridSize ( )

Disable mouse dragging of grid lines to resize rows and columns.

Equivalent to passing false to EnableDragGridSize()

void wxGrid::DisableDragRowSize ( )

Disables row sizing by dragging with the mouse.

Equivalent to passing false to EnableDragRowSize().

void wxGrid::DisableRowResize ( int row )

Disable interactive resizing of the specified row.

This is the same as DisableColResize() but for rows.

参照:: EnableDragRowSize()

void wxGrid::EnableCellEditControl ( bool enable = true )

Enables or disables in-place editing of grid cell data.

The grid will issue either a wxEVT_GRID_EDITOR_SHOWN or wxEVT_GRID_EDITOR_HIDDEN event.

void wxGrid::EnableDragCell ( bool enable = true )

Enables or disables cell dragging with the mouse.

void wxGrid::EnableDragColMove ( bool enable = true )

Enables or disables column moving by dragging with the mouse.

void wxGrid::EnableDragColSize ( bool enable = true )

Enables or disables column sizing by dragging with the mouse.

参照:: DisableColResize()

void wxGrid::EnableDragGridSize ( bool enable = true )

Enables or disables row and column resizing by dragging gridlines with the mouse.

void wxGrid::EnableDragRowSize ( bool enable = true )

Enables or disables row sizing by dragging with the mouse.

参照:: DisableRowResize()

void wxGrid::EnableEditing ( bool edit )

Makes the grid globally editable or read-only.

If the edit argument is false this function sets the whole grid as read-only. If the argument is true the grid is set to the default state where cells may be editable. In the default state you can set single grid cells and whole rows and columns to be editable or read-only via wxGridCellAttr::SetReadOnly(). For single cells you can also use the shortcut function SetReadOnly().

For more information about controlling grid cell attributes see the wxGridCellAttr class and the wxGrid Overview.

void wxGrid::EnableGridLines ( bool enable = true )

Turns the drawing of grid lines on or off.

void wxGrid::EndBatch ( )

Decrements the grid's batch count.

When the count is greater than zero repainting of the grid is suppressed. Each previous call to BeginBatch() must be matched by a later call to EndBatch(). Code that does a lot of grid modification can be enclosed between BeginBatch() and EndBatch() calls to avoid screen flicker. The final EndBatch() will cause the grid to be repainted.

参照:: wxGridUpdateLocker

virtual void wxGrid::Fit ( ) [virtual]

Overridden wxWindow method.

void wxGrid::ForceRefresh ( )

Causes immediate repainting of the grid.

Use this instead of the usual wxWindow::Refresh().

int wxGrid::GetBatchCount ( )

Returns the number of times that BeginBatch() has been called without (yet) matching calls to EndBatch().

While the grid's batch count is greater than zero the display will not be updated.

void wxGrid::GetCellAlignment	(	int	row,
		int	col,
		int *	horiz,
		int *	vert
	)		const

Sets the arguments to the horizontal and vertical text alignment values for the grid cell at the specified location.

Horizontal alignment will be one of wxALIGN_LEFT, wxALIGN_CENTRE or wxALIGN_RIGHT.

Vertical alignment will be one of wxALIGN_TOP, wxALIGN_CENTRE or wxALIGN_BOTTOM.

wxColour wxGrid::GetCellBackgroundColour	(	int	row,
		int	col
	)		const

Returns the background colour of the cell at the specified location.

wxGridCellEditor* wxGrid::GetCellEditor	(	int	row,
		int	col
	)		const

Returns a pointer to the editor for the cell at the specified location.

See wxGridCellEditor and the wxGrid Overview for more information about cell editors and renderers.

The caller must call DecRef() on the returned pointer.

wxFont wxGrid::GetCellFont	(	int	row,
		int	col
	)		const

Returns the font for text in the grid cell at the specified location.

wxGridCellRenderer* wxGrid::GetCellRenderer	(	int	row,
		int	col
	)		const

Returns a pointer to the renderer for the grid cell at the specified location.

See wxGridCellRenderer and the wxGrid Overview for more information about cell editors and renderers.

The caller must call DecRef() on the returned pointer.

CellSpan wxGrid::GetCellSize	(	int	row,
		int	col,
		int *	num_rows,
		int *	num_cols
	)		const

Get the size of the cell in number of cells covered by it.

For normal cells, the function fills both num_rows and num_cols with 1 and returns CellSpan_None. For cells which span multiple cells, i.e. for which SetCellSize() had been called, the returned values are the same ones as were passed to SetCellSize() call and the function return value is CellSpan_Main.

More unexpectedly, perhaps, the returned values may be negative for the cells which are inside a span covered by a cell occupying multiple rows or columns. They correspond to the offset of the main cell of the span from the cell passed to this functions and the function returns CellSpan_Inside value to indicate this.

As an example, consider a 3*3 grid with the cell (1, 1) (the one in the middle) having a span of 2 rows and 2 columns, i.e. the grid looks like

            +----+----+----+
            |    |    |    |
            +----+----+----+
            |    |         |
            +----+         |
            |    |         |
            +----+----+----+

Then the function returns 2 and 2 in num_rows and num_cols for the cell (1, 1) itself and -1 and -1 for the cell (2, 2) as well as -1 and 0 for the cell (2, 1).

Parameters:

row	The row of the cell.
col	The column of the cell.
num_rows	Pointer to variable receiving the number of rows, must not be NULL.
num_cols	Pointer to variable receiving the number of columns, must not be NULL.

Returns:: The kind of this cell span (the return value is new in wxWidgets 2.9.1, this function was void in previous wxWidgets versions).

wxSize wxGrid::GetCellSize ( const wxGridCellCoords & coords )

Get the number of rows and columns allocated for this cell.

This overload doesn't return a CellSpan value but the values returned may still be negative, see GetCellSize(int, int, int *, int *) for details.

wxColour wxGrid::GetCellTextColour	(	int	row,
		int	col
	)		const

Returns the text colour for the grid cell at the specified location.

wxString wxGrid::GetCellValue ( const wxGridCellCoords & coords ) const

Returns the string contained in the cell at the specified location.

For simple applications where a grid object automatically uses a default grid table of string values you use this function together with SetCellValue() to access cell values. For more complex applications where you have derived your own grid table class that contains various data types (e.g. numeric, boolean or user-defined custom types) then you only use this function for those cells that contain string values.

See wxGridTableBase::CanGetValueAs() and the wxGrid Overview for more information.

		int	col
	)		const

Return the column labels window.

This window is not shown if the columns labels were hidden using HideColLabels().

Depending on whether UseNativeColHeader() was called or not this can be either a wxHeaderCtrl or a plain wxWindow. This function returns a valid window pointer in either case but in the former case you can also use GetGridColHeader() to access it if you need wxHeaderCtrl-specific functionality.

wxWindow* wxGrid::GetGridCornerLabelWindow ( ) const

Return the window in the top left grid corner.

This window is shown only of both columns and row labels are shown and normally doesn't contain anything. Clicking on it is handled by wxGrid however and can be used to select the entire grid.

If the cell already has an attribute, it is returned. Otherwise a new attribute is created, associated with the cell and returned. In any case the caller must call DecRef() on the returned pointer.

This function may only be called if CanHaveAttributes() returns true.

virtual wxPen wxGrid::GetRowGridLinePen ( int row ) [virtual]

Returns the pen used for horizontal grid lines.

This virtual function may be overridden in derived classes in order to change the appearance of individual grid line for the given row.

Returns the minimal size to which rows can be resized.

Use SetRowMinimalAcceptableHeight() to change this value globally or SetRowMinimalHeight() to do it for individual cells.

参照:: GetColMinimalAcceptableWidth()

int wxGrid::GetRowMinimalHeight ( int col ) const [protected]

Returns the minimal size for the given column.

The value returned by this function may be different than that returned by GetRowMinimalAcceptableHeight() if SetRowMinimalHeight() had been called for this row.

int wxGrid::GetRowSize ( int row ) const

Returns the height of the specified row.

wxGridSizesInfo wxGrid::GetRowSizes ( ) const

Get size information for all row at once.

int wxGrid::GetScrollLineY ( ) const

Returns the number of pixels per vertical scroll increment.

The default is 15.

参照:: GetScrollLineX(), SetScrollLineX(), SetScrollLineY()

wxGridCellCoordsArray wxGrid::GetSelectedCells ( ) const

Returns an array of individually selected cells.

Notice that this array does not contain all the selected cells in general as it doesn't include the cells selected as part of column, row or block selection. You must use this method, GetSelectedCols(), GetSelectedRows() and GetSelectionBlockTopLeft() and GetSelectionBlockBottomRight() methods to obtain the entire selection in general.

Please notice this behaviour is by design and is needed in order to support grids of arbitrary size (when an entire column is selected in a grid with a million of columns, we don't want to create an array with a million of entries in this function, instead it returns an empty array and GetSelectedCols() returns an array containing one element).

wxArrayInt wxGrid::GetSelectedCols ( ) const

Returns an array of selected columns.

Please notice that this method alone is not sufficient to find all the selected columns as it contains only the columns which were individually selected but not those being part of the block selection or being selected in virtue of all of their cells being selected individually, please see GetSelectedCells() for more details.

wxArrayInt wxGrid::GetSelectedRows ( ) const

Returns an array of selected rows.

Please notice that this method alone is not sufficient to find all the selected rows as it contains only the rows which were individually selected but not those being part of the block selection or being selected in virtue of all of their cells being selected individually, please see GetSelectedCells() for more details.

wxColour wxGrid::GetSelectionBackground ( ) const

Returns the colour used for drawing the selection background.

wxGridCellCoordsArray wxGrid::GetSelectionBlockBottomRight ( ) const

Returns an array of the bottom right corners of blocks of selected cells.

Please see GetSelectedCells() for more information about the selection representation in wxGrid.

参照:: GetSelectionBlockTopLeft()

wxGridCellCoordsArray wxGrid::GetSelectionBlockTopLeft ( ) const

Returns an array of the top left corners of blocks of selected cells.

Please see GetSelectedCells() for more information about the selection representation in wxGrid.

参照:: GetSelectionBlockBottomRight()

wxColour wxGrid::GetSelectionForeground ( ) const

Returns the colour used for drawing the selection foreground.

wxGridSelectionModes wxGrid::GetSelectionMode ( ) const

Returns the current selection mode.

参照:: SetSelectionMode().

int wxGrid::GetSortingColumn ( ) const

Return the column in which the sorting indicator is currently displayed.

Returns wxNOT_FOUND if sorting indicator is not currently displayed at all.

参照:: SetSortingColumn()

wxGridTableBase* wxGrid::GetTable ( ) const

Returns a base pointer to the current table object.

The returned pointer is still owned by the grid.

void wxGrid::GoToCell	(	int	row,
		int	col
	)

Make the given cell current and ensure it is visible.

This method is equivalent to calling MakeCellVisible() and SetGridCursor() and so, as with the latter, a wxEVT_GRID_SELECT_CELL event is generated by it and the selected cell doesn't change if the event is vetoed.

void wxGrid::GoToCell ( const wxGridCellCoords & coords )

Make the given cell current and ensure it is visible.

This method is equivalent to calling MakeCellVisible() and SetGridCursor() and so, as with the latter, a wxEVT_GRID_SELECT_CELL event is generated by it and the selected cell doesn't change if the event is vetoed.

bool wxGrid::GridLinesEnabled ( ) const

Returns true if drawing of grid lines is turned on, false otherwise.

void wxGrid::HideCellEditControl ( )

Hides the in-place cell edit control.

void wxGrid::HideCol ( int col )

Hides the specified column.

To show the column later you need to call SetColSize() with non-0 width or ShowCol().

Parameters:

col	The column index.

void wxGrid::HideColLabels ( )

Hides the column labels by calling SetColLabelSize() with a size of 0.

Show labels again by calling that method with a width greater than 0.

void wxGrid::HideRow ( int col )

Hides the specified row.

To show the row later you need to call SetRowSize() with non-0 width or ShowRow().

Parameters:

col	The row index.

void wxGrid::HideRowLabels ( )

Hides the row labels by calling SetRowLabelSize() with a size of 0.

The labels can be shown again by calling SetRowLabelSize() with a width greater than 0.

bool wxGrid::InsertCols	(	int	pos = `0`,
		int	numCols = `1`,
		bool	updateLabels = `true`
	)

Inserts one or more new columns into a grid with the first new column at the specified position.

Notice that inserting the columns in the grid requires grid table cooperation: when this method is called, grid object begins by requesting the underlying grid table to insert new columns. If this is successful the table notifies the grid and the grid updates the display. For a default grid (one where you have called CreateGrid()) this process is automatic. If you are using a custom grid table (specified with SetTable()) then you must override wxGridTableBase::InsertCols() in your derived table class.

Parameters:

pos	The position which the first newly inserted column will have.
numCols	The number of columns to insert.
updateLabels	Currently not used.

Returns:: true if the columns were successfully inserted, false if an error occurred (most likely the table couldn't be updated).

bool wxGrid::InsertRows	(	int	pos = `0`,
		int	numRows = `1`,
		bool	updateLabels = `true`
	)

Inserts one or more new rows into a grid with the first new row at the specified position.

Notice that you must implement wxGridTableBase::InsertRows() if you use a grid with a custom table, please see InsertCols() for more information.

Parameters:

pos	The position which the first newly inserted row will have.
numRows	The number of rows to insert.
updateLabels	Currently not used.

Returns:: true if the rows were successfully inserted, false if an error occurred (most likely the table couldn't be updated).

bool wxGrid::IsCellEditControlEnabled ( ) const

Returns true if the in-place edit control is currently enabled.

bool wxGrid::IsColShown ( int col ) const

Returns true if the specified column is not currently hidden.

bool wxGrid::IsCurrentCellReadOnly ( ) const

Returns true if the current cell is read-only.

参照:: SetReadOnly(), IsReadOnly()

bool wxGrid::IsEditable ( ) const

Returns false if the whole grid has been set as read-only or true otherwise.

See EnableEditing() for more information about controlling the editing status of grid cells.

bool wxGrid::IsInSelection ( const wxGridCellCoords & coords ) const

Returns true if the given cell is selected.

bool wxGrid::IsInSelection	(	int	row,
		int	col
	)		const

Returns true if the given cell is selected.

bool wxGrid::IsReadOnly	(	int	row,
		int	col
	)		const

Returns true if the cell at the specified location can't be edited.

参照:: SetReadOnly(), IsCurrentCellReadOnly()

bool wxGrid::IsRowShown ( int row ) const

Returns true if the specified row is not currently hidden.

bool wxGrid::IsSelection ( ) const

Returns true if there are currently any selected cells, rows, columns or blocks.

bool wxGrid::IsSortingBy ( int col ) const

Return true if this column is currently used for sorting.

参照:: GetSortingColumn()

bool wxGrid::IsSortOrderAscending ( ) const

Return true if the current sorting order is ascending or false if it is descending.

It only makes sense to call this function if GetSortingColumn() returns a valid column index and not wxNOT_FOUND.

参照:: SetSortingColumn()

bool wxGrid::IsVisible	(	int	row,
		int	col,
		bool	wholeCellVisible = `true`
	)		const

Returns true if a cell is either entirely or at least partially visible in the grid window.

By default, the cell must be entirely visible for this function to return true but if wholeCellVisible is false, the function returns true even if the cell is only partially visible.

bool wxGrid::IsVisible	(	const wxGridCellCoords &	coords,
		bool	wholeCellVisible = `true`
	)		const

Returns true if a cell is either entirely or at least partially visible in the grid window.

By default, the cell must be entirely visible for this function to return true but if wholeCellVisible is false, the function returns true even if the cell is only partially visible.

void wxGrid::MakeCellVisible ( const wxGridCellCoords & coords )

Brings the specified cell into the visible grid cell area with minimal scrolling.

Does nothing if the cell is already visible.

void wxGrid::MakeCellVisible	(	int	row,
		int	col
	)

Brings the specified cell into the visible grid cell area with minimal scrolling.

Does nothing if the cell is already visible.
