Detailed Description

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.

the width of each field is the width of the widest child, the height of each field is the height of the tallest child.

Constructor & Destructor Documentation

wxGridSizer::wxGridSizer	(	int	cols,
		int	vgap,
		int	hgap
	)

wxGridSizer 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 wxSize 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.

Since: 2.9.1 (except for the four argument overload)
