- @a rows and @a cols determine the number of columns and rows in the sizer -
- if either of the parameters is zero, it will be calculated to form the
- total number of children in the sizer, thus making the sizer grow
- dynamically.
+ Usually only the number of columns in the flex grid sizer needs to be
+ specified using @a cols argument. The number of rows will be deduced
+ automatically depending on the number of the elements added to the
+ sizer. If the number of @a rows is explicitly specified (and not zero),
+ the sizer will check that it no more than @code cols*rows @endcode
+ elements are added to it.
+
+ The @a gap (or @a vgap and @a 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 @a vgap) and columns
+ (its horizontal component, or @a hgap), in pixels.
