Constructor & Destructor Documentation

wxGridCellAttr::wxGridCellAttr ( wxGridCellAttr attrDefault = NULL)

Default constructor.

wxGridCellAttr::wxGridCellAttr ( const wxColour colText,
const wxColour colBack,
const wxFont font,
int  hAlign,
int  vAlign 
)

Constructor specifying some of the often used attributes.


Member Function Documentation

wxGridCellAttr* wxGridCellAttr::Clone ( ) const

Creates a new copy of this object.

void wxGridCellAttr::DecRef ( )

This class is reference counted: it is created with ref count of 1, so calling DecRef() once will delete it.

Calling IncRef() allows to lock it until the matching DecRef() is called.

void wxGridCellAttr::GetAlignment ( int *  hAlign,
int *  vAlign 
) const

Get the alignment to use for the cell with the given attribute.

If this attribute doesn't specify any alignment, the default attribute alignment is used (which can be changed using wxGrid::SetDefaultCellAlignment() but is left and top by default).

Notice that hAlign and vAlign values are always overwritten by this function, use GetNonDefaultAlignment() if this is not desirable.

Parameters:
hAlignHorizontal alignment is returned here if this argument is non-NULL. It is one of wxALIGN_LEFT, wxALIGN_CENTRE or wxALIGN_RIGHT.
vAlignVertical alignment is returned here if this argument is non-NULL. It is one of wxALIGN_TOP, wxALIGN_CENTRE or wxALIGN_BOTTOM.
const wxColour& wxGridCellAttr::GetBackgroundColour ( ) const

Returns the background colour.

wxGridCellEditor* wxGridCellAttr::GetEditor ( const wxGrid grid,
int  row,
int  col 
) const

Returns the cell editor.

const wxFont& wxGridCellAttr::GetFont ( ) const

Returns the font.

void wxGridCellAttr::GetNonDefaultAlignment ( int *  hAlign,
int *  vAlign 
) const

Get the alignment defined by this attribute.

Unlike GetAlignment() this function only modifies hAlign and vAlign if this attribute does define a non-default alignment. This means that they must be initialized before calling this function and that their values will be preserved unchanged if they are different from wxALIGN_INVALID.

For example, the following fragment can be used to use the cell alignment if one is defined but right-align its contents by default (instead of left-aligning it by default) while still using the default vertical alignment:

            int hAlign = wxALIGN_RIGHT,
                vAlign = wxALIGN_INVALID;
            attr.GetNonDefaultAlignment(&hAlign, &vAlign);
Since:
2.9.1
wxGridCellRenderer* wxGridCellAttr::GetRenderer ( const wxGrid grid,
int  row,
int  col 
) const

Returns the cell renderer.

const wxColour& wxGridCellAttr::GetTextColour ( ) const

Returns the text colour.

bool wxGridCellAttr::HasAlignment ( ) const

Returns true if this attribute has a valid alignment set.

bool wxGridCellAttr::HasBackgroundColour ( ) const

Returns true if this attribute has a valid background colour set.

bool wxGridCellAttr::HasEditor ( ) const

Returns true if this attribute has a valid cell editor set.

bool wxGridCellAttr::HasFont ( ) const

Returns true if this attribute has a valid font set.

bool wxGridCellAttr::HasRenderer ( ) const

Returns true if this attribute has a valid cell renderer set.

bool wxGridCellAttr::HasTextColour ( ) const

Returns true if this attribute has a valid text colour set.

void wxGridCellAttr::IncRef ( )

This class is reference counted: it is created with ref count of 1, so calling DecRef() once will delete it.

Calling IncRef() allows to lock it until the matching DecRef() is called.

bool wxGridCellAttr::IsReadOnly ( ) const

Returns true if this cell is set as read-only.

void wxGridCellAttr::SetAlignment ( int  hAlign,
int  vAlign 
)

Sets the alignment.

hAlign can be one of wxALIGN_LEFT, wxALIGN_CENTRE or wxALIGN_RIGHT and vAlign can be one of wxALIGN_TOP, wxALIGN_CENTRE or wxALIGN_BOTTOM.

void wxGridCellAttr::SetBackgroundColour ( const wxColour colBack)

Sets the background colour.

void wxGridCellAttr::SetDefAttr ( wxGridCellAttr defAttr)
Todo:
Needs documentation.
void wxGridCellAttr::SetEditor ( wxGridCellEditor editor)

Sets the editor to be used with the cells with this attribute.

void wxGridCellAttr::SetFont ( const wxFont font)

Sets the font.

void wxGridCellAttr::SetReadOnly ( bool  isReadOnly = true)

Sets the cell as read-only.

void wxGridCellAttr::SetRenderer ( wxGridCellRenderer renderer)

Sets the renderer to be used for cells with this attribute.

Takes ownership of the pointer.

void wxGridCellAttr::SetTextColour ( const wxColour colText)

Sets the text colour.
