+Since wxWindows 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 
+\helpref{SetFlexibleDrection}{wxflexgridsizersetflexibledrection}),
+it needs to be decided how the sizer should grow in the other ("non flexible")
+direction in order to fill the available space. The 
+\helpref{SetNonFlexibleGrowMode}{wxflexgridsizersetnonflexiblegrowmode} method
+serves this purpose.
