Each sizer has a Layout function.
wxExpandSizer::Layout ; E.g. for resizeable windows
-
+
- parent size must be known (i.e. called
from OnSize or explicitly)
- call Layout on each child to give it a chance to resize
wxShrinkSizer::Layout ; E.g. fit-to-contents windows
; Perhaps 2 rowcols, one above other.
-
+
- call Layout on each child to give it a chance to resize
(e.g. child shrinks around its own children):
stop when each returns TRUE, or no change
How to relayout if a child sizer/window changes? Need to go all the way
to the top of the hierarchy and call Layout() again.
-
+
wxRowColSizer::Layout
- Similar to wxShrinkSizer only instead of shrinking to fit
contents, more sophisticated layout of contents, and THEN
shrinking (possibly).
- Do the same parent window check/setsize as for wxShrinkSizer.
