A flex grid sizer is a sizer which lays out its children in a two-dimensional table with all table fields in one row having the same height and all fields in one column having the same width, but all rows or all columns are not necessarily the same height or width as in the wxGridSizer.
Since wxWidgets 2.5.0, wxFlexGridSizer can also size items equally in one direction but unequally ("flexibly") in the other. If the sizer is only flexible in one direction (this can be changed using wxFlexGridSizer::SetFlexibleDirection), it needs to be decided how the sizer should grow in the other ("non-flexible") direction in order to fill the available space. The wxFlexGridSizer::SetNonFlexibleGrowMode() method serves this purpose.

void | AddGrowableCol (size_t idx, int proportion=0) |
Specifies that column idx (starting from zero) should be grown if there is extra space available to the sizer. | |
void | AddGrowableRow (size_t idx, int proportion=0) |
Specifies that row idx (starting from zero) should be grown if there is extra space available to the sizer. | |
int | GetFlexibleDirection () const |
Returns a wxOrientation value that specifies whether the sizer flexibly resizes its columns, rows, or both (default). | |
wxFlexSizerGrowMode | GetNonFlexibleGrowMode () const |
Returns the value that specifies how the sizer grows in the "non-flexible" direction if there is one. | |
bool | IsColGrowable (size_t idx) |
Returns true if column idx is growable. | |
bool | IsRowGrowable (size_t idx) |
Returns true if row idx is growable. | |
void | RemoveGrowableCol (size_t idx) |
Specifies that the idx column index is no longer growable. | |
void | RemoveGrowableRow (size_t idx) |
Specifies that the idx row index is no longer growable. | |
void | SetFlexibleDirection (int direction) |
Specifies whether the sizer should flexibly resize its columns, rows, or both. | |
void | SetNonFlexibleGrowMode (wxFlexSizerGrowMode mode) |
Specifies how the sizer should grow in the non-flexible direction if there is one (so SetFlexibleDirection() must have been called previously). | |

void wxFlexGridSizer::AddGrowableCol | ( | size_t | idx, |
int | proportion = 0 |
||
) |
Specifies that column idx (starting from zero) should be grown if there is extra space available to the sizer.
The proportion parameter has the same meaning as the stretch factor for the sizers (see wxBoxSizer) except that if all proportions are 0, then all columns are resized equally (instead of not being resized at all).
Notice that the column must not be already growable, if you need to change the proportion you must call RemoveGrowableCol() first and then make it growable (with a different proportion) again. You can use IsColGrowable() to check whether a column is already growable.
void wxFlexGridSizer::AddGrowableRow | ( | size_t | idx, |
int | proportion = 0 |
||
) |
Specifies that row idx (starting from zero) should be grown if there is extra space available to the sizer.
This is identical to AddGrowableCol() except that it works with rows and not columns.
virtual wxSize wxFlexGridSizer::CalcMin | ( | ) | [virtual] |
This method is abstract and has to be overwritten by any derived class.
Here, the sizer will do the actual calculation of its children's minimal sizes.
Reimplemented from wxGridSizer.
Reimplemented in wxGridBagSizer.
int wxFlexGridSizer::GetFlexibleDirection | ( | ) | const |
Returns a wxOrientation value that specifies whether the sizer flexibly resizes its columns, rows, or both (default).
wxFlexSizerGrowMode wxFlexGridSizer::GetNonFlexibleGrowMode | ( | ) | const |
Returns the value that specifies how the sizer grows in the "non-flexible" direction if there is one.
The behaviour of the elements in the flexible direction (i.e. both rows and columns by default, or rows only if GetFlexibleDirection() is wxVERTICAL
or columns only if it is wxHORIZONTAL
) is always governed by their proportion as specified in the call to AddGrowableRow() or AddGrowableCol(). What happens in the other direction depends on the value of returned by this function as described below.
bool wxFlexGridSizer::IsColGrowable | ( | size_t | idx | ) |
Returns true if column idx is growable.
bool wxFlexGridSizer::IsRowGrowable | ( | size_t | idx | ) |
Returns true if row idx is growable.
virtual void wxFlexGridSizer::RecalcSizes | ( | ) | [virtual] |
This method is abstract and has to be overwritten by any derived class.
Here, the sizer will do the actual calculation of its children's positions and sizes.

void wxFlexGridSizer::RemoveGrowableCol | ( | size_t | idx | ) |
Specifies that the idx column index is no longer growable.
void wxFlexGridSizer::RemoveGrowableRow | ( | size_t | idx | ) |
Specifies that the idx row index is no longer growable.
void wxFlexGridSizer::SetFlexibleDirection | ( | int | direction | ) |
Specifies whether the sizer should flexibly resize its columns, rows, or both.
Argument direction can be wxVERTICAL
, wxHORIZONTAL
or wxBOTH
(which is the default value). Any other value is ignored.
See GetFlexibleDirection() for the explanation of these values. Note that this method does not trigger relayout.
void wxFlexGridSizer::SetNonFlexibleGrowMode | ( | wxFlexSizerGrowMode | mode | ) |
Specifies how the sizer should grow in the non-flexible direction if there is one (so SetFlexibleDirection() must have been called previously).
Argument mode can be one of those documented in GetNonFlexibleGrowMode(), please see there for their explanation. Note that this method does not trigger relayout.
