4397 // Getting the Y position for a window, like a control, is a real
4398 // pain. There are three sitatuions we must deal with in determining
4399 // the OS2 to wxWidgets Y coordinate.
4400 //
4401 // 1) The controls are created in a dialog.
4402 // This is the easiest since a dialog is created with its original
4403 // size so the standard: Y = ParentHeight - (Y + ControlHeight);
4404 //
4405 // 2) The controls are direct children of a frame
4406 // In this instance the controls are actually children of the Frame's
4407 // client. During creation the frame's client resizes several times
4408 // during creation of the status bar and toolbars. The CFrame class
4409 // will take care of this using its AlterChildPos proc.
4410 //
4411 // 3) The controls are children of a panel, which in turn is a child of
4412 // a frame.
4413 // The panel may be one of many, in which case the same treatment
4414 // as 1 applies. It may be the only child, though.
4415 // This is the nastiest case. A panel is created as the only child of
4416 // the frame and as such, when a frame has only one child, the child is
4417 // expanded to fit the entire client area of the frame. Because the
4418 // controls are created BEFORE this occurs their positions are totally
4419 // whacked and any call to WinQueryWindowPos will return invalid
4420 // coordinates. So for this situation we have to compare the size of
4421 // the panel at control creation time with that of the frame client. If
4422 // they are the same we can use the standard Y position equation. If
4423 // not, then we must use the Frame Client's dimensions to position them
4424 // as that will be the eventual size of the panel after the frame resizes
4425 // it!
