4473 //
4474 // 2) The controls are direct children of a frame
4475 // In this instance the controls are actually children of the Frame's
4476 // client. During creation the frame's client resizes several times
4477 // during creation of the status bar and toolbars. The CFrame class
4478 // will take care of this using its AlterChildPos proc.
4479 //

4481 // a frame.
4482 // The panel may be one of many, in which case the same treatment

4485 // the frame and as such, when a frame has only one child, the child is
4486 // expanded to fit the entire client area of the frame. Because the
4487 // controls are created BEFORE this occurs their positions are totally
4488 // whacked and any call to WinQueryWindowPos will return invalid
4489 // coordinates. So for this situation we have to compare the size of
4490 // the panel at control creation time with that of the frame client. If
4491 // they are the same we can use the standard Y position equation. If
