A grid sizer is a sizer which lays out its children in a twodimensional table with all table fields having the same size, i.e.
the width of each field is the width of the widest child, the height of each field is the height of the tallest child.

GridSizer
(Sizer)¶Possible constructors:
GridSizer(cols, vgap, hgap)
GridSizer(cols, gap=Size(0,0))
GridSizer(rows, cols, vgap, hgap)
GridSizer(rows, cols, gap)
A grid sizer is a sizer which lays out its children in a two dimensional table with all table fields having the same size, i.e.
__init__
(self, *args, **kw)¶wx.GridSizer constructors.
Usually only the number of columns in the flex grid sizer needs to be specified using cols argument. The number of rows will be deduced automatically depending on the number of the elements added to the sizer.
If a constructor form with rows parameter is used (and the value of rows argument is not zero, meaning “unspecified”) the sizer will check that no more than cols*rows
elements are added to it, i.e. that no more than the given number of rows is used. Adding less than maximally allowed number of items is not an error however.
Finally, it is also possible to specify the number of rows and use 0 for cols. In this case, the sizer will use the given fixed number of rows and as many columns as necessary.
The gap (or vgap and hgap, which correspond to the height and width of the wx.Size object) argument defines the size of the padding between the rows (its vertical component, or vgap) and columns (its horizontal component, or hgap), in pixels.
New in version 2.9.1: (except for the four argument overload)
__init__ (self, cols, vgap, hgap)
Parameters: 


__init__ (self, cols, gap=Size(0,0))
Parameters: 


__init__ (self, rows, cols, vgap, hgap)
Parameters: 


__init__ (self, rows, cols, gap)
Parameters: 


CalcMin
(self)¶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.
Return type:  wx.Size 

CalcRowsCols
(self)¶Calculates how many rows and columns will be in the sizer based on the current number of items and also the rows, cols specified in the constructor.
GetCols
(self)¶Returns the number of columns that has been specified for the sizer.
Returns zero if the sizer is automatically adjusting the number of columns depending on number of its children. To get the effective number of columns or rows being currently used, see GetEffectiveColsCount
Return type:  int 

GetEffectiveColsCount
(self)¶Returns the number of columns currently used by the sizer.
This will depend on the number of children the sizer has if the sizer is automatically adjusting the number of columns/rows.
Return type:  int 

New in version 2.9.1.
GetEffectiveRowsCount
(self)¶Returns the number of rows currently used by the sizer.
This will depend on the number of children the sizer has if the sizer is automatically adjusting the number of columns/rows.
Return type:  int 

New in version 2.9.1.
GetHGap
(self)¶Returns the horizontal gap (in pixels) between cells in the sizer.
Return type:  int 

GetRows
(self)¶Returns the number of rows that has been specified for the sizer.
Returns zero if the sizer is automatically adjusting the number of rows depending on number of its children. To get the effective number of columns or rows being currently used, see GetEffectiveRowsCount
.
Return type:  int 

GetVGap
(self)¶Returns the vertical gap (in pixels) between the cells in the sizer.
Return type:  int 

RepositionChildren
(self, minSize)¶Method which must be overridden in the derived sizer classes.
The implementation should reposition the children using the current total size available to the sizer ( m_size
) and the size computed by the last call to CalcMin
.
Parameters:  minSize (wx.Size) – 

New in version 3.1.3,: before this version RecalcSizes() method not taking any arguments had to be overridden in the derived classes instead.
SetCols
(self, cols)¶Sets the number of columns in the sizer.
Parameters:  cols (int) – 

SetHGap
(self, gap)¶Sets the horizontal gap (in pixels) between cells in the sizer.
Parameters:  gap (int) – 

SetRows
(self, rows)¶Sets the number of rows in the sizer.
Parameters:  rows (int) – 

SetVGap
(self, gap)¶Sets the vertical gap (in pixels) between the cells in the sizer.
Parameters:  gap (int) –
