4374 // In this instance the controls are actually children of the Frame's
4375 // client. During creation the frame's client resizes several times
4376 // during creation of the status bar and toolbars. The CFrame class
4377 // will take care of this using its AlterChildPos proc.
4378 //
4379 // 3) The controls are children of a panel, which in turn is a child of
4380 // a frame.
4381 // The panel may be one of many, in which case the same treatment
4382 // as 1 applies. It may be the only child, though.
4383 // This is the nastiest case. A panel is created as the only child of
4384 // the frame and as such, when a frame has only one child, the child is
4385 // expanded to fit the entire client area of the frame. Because the
4386 // controls are created BEFORE this occurs their positions are totally
4387 // whacked and any call to WinQueryWindowPos will return invalid
4388 // coordinates. So for this situation we have to compare the size of
4389 // the panel at control creation time with that of the frame client. If
4390 // they are the same we can use the standard Y position equation. If
4391 // not, then we must use the Frame Client's dimensions to position them
4392 // as that will be the eventual size of the panel after the frame resizes
4393 // it!
4394 //
