4 user. It usually has thick borders and a title bar, and can optionally contain
5 a menu bar, toolbar and status bar. A frame can contain any window that is not

66 The default frame style is for normal, resizeable frames. To create a frame

\_SIZE}{wxsizeevent
}}{If the frame has exactly one
79 child window, not counting the status and toolbar, this child is resized to

376 forcing it to reevaluate its children positions. It is sometimes useful to call
377 this function after adding or deleting a children after the frame creation or
378 if a child size changes.
380 Note that if the frame is using either sizers or constraints for the children
381 layout, it is enough to call
\helpref{Layout()
}{wxwindowlayout

382 this function should not be used in this case.
