4470// Getting the Y position for a window, like a control, is a real
4471// pain. There are three sitatuions we must deal with in determining
4472// the OS2 to wxWindows Y coordinate.
4473//
4474// 1) The controls are created in a dialog.
4475// This is the easiest since a dialog is created with its original
4476// size so the standard: Y = ParentHeight - (Y + ControlHeight);
4477//
4478// 2) The controls are direct children of a frame
4479// In this instance the controls are actually children of the Frame's
4480// client. During creation the frame's client resizes several times
4481// during creation of the status bar and toolbars. The CFrame class
4482// will take care of this using its AlterChildPos proc.
4483//
4484// 3) The controls are children of a panel, which in turn is a child of
4485// a frame.
4486// The panel may be one of many, in which case the same treatment
4487// as 1 applies. It may be the only child, though.
4488// This is the nastiest case. A panel is created as the only child of
4489// the frame and as such, when a frame has only one child, the child is
4490// expanded to fit the entire client area of the frame. Because the
4491// controls are created BEFORE this occurs their positions are totally
4492// whacked and any call to WinQueryWindowPos will return invalid
4493// coordinates. So for this situation we have to compare the size of
4494// the panel at control creation time with that of the frame client. If
4495// they are the same we can use the standard Y position equation. If
4496// not, then we must use the Frame Client's dimensions to position them
4497// as that will be the eventual size of the panel after the frame resizes
4498// it!
