4389 // Getting the Y position for a window, like a control, is a real
4390 // pain. There are three sitatuions we must deal with in determining
4391 // the OS2 to wxWidgets Y coordinate.
4392 //
4393 // 1) The controls are created in a dialog.
4394 // This is the easiest since a dialog is created with its original
4395 // size so the standard: Y = ParentHeight - (Y + ControlHeight);
4396 //
4397 // 2) The controls are direct children of a frame
4398 // In this instance the controls are actually children of the Frame's
4399 // client. During creation the frame's client resizes several times
4400 // during creation of the status bar and toolbars. The CFrame class
4401 // will take care of this using its AlterChildPos proc.
4402 //
4403 // 3) The controls are children of a panel, which in turn is a child of
4404 // a frame.
4405 // The panel may be one of many, in which case the same treatment
4406 // as 1 applies. It may be the only child, though.
4407 // This is the nastiest case. A panel is created as the only child of
4408 // the frame and as such, when a frame has only one child, the child is
4409 // expanded to fit the entire client area of the frame. Because the
4410 // controls are created BEFORE this occurs their positions are totally
4411 // whacked and any call to WinQueryWindowPos will return invalid
4412 // coordinates. So for this situation we have to compare the size of
4413 // the panel at control creation time with that of the frame client. If
4414 // they are the same we can use the standard Y position equation. If
4415 // not, then we must use the Frame Client's dimensions to position them
4416 // as that will be the eventual size of the panel after the frame resizes
4417 // it!
