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