4465 // the OS2 to wxWindows Y coordinate.
4466 //
4467 // 1) The controls are created in a dialog.
4468 // This is the easiest since a dialog is created with its original
4469 // size so the standard: Y = ParentHeight - (Y + ControlHeight);
4470 //
4471 // 2) The controls are direct children of a frame
4472 // In this instance the controls are actually children of the Frame's
4473 // client. During creation the frame's client resizes several times
4474 // during creation of the status bar and toolbars. The CFrame class
4475 // will take care of this using its AlterChildPos proc.
4476 //
4477 // 3) The controls are children of a panel, which in turn is a child of
4478 // a frame.
4479 // The panel may be one of many, in which case the same treatment
4480 // as 1 applies. It may be the only child, though.

4482 // the frame and as such, when a frame has only one child, the child is
4483 // expanded to fit the entire client area of the frame. Because the
4484 // controls are created BEFORE this occurs their positions are totally
4485 // whacked and any call to WinQueryWindowPos will return invalid
4486 // coordinates. So for this situation we have to compare the size of
4487 // the panel at control creation time with that of the frame client. If
4488 // they are the same we can use the standard Y position equation. If
4489 // not, then we must use the Frame Client's dimensions to position them
