+
+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 for a wxGridSizer. {\it rows} and {\it cols} determine the number of
+columns and rows in the sizer - if either of the parameters is zero, it will be
+calculated form the total number of children in the sizer, thus making the
+sizer grow dynamically. {\it vgap} and {\it hgap} define extra space between
+all children.
