4473 // 1) The controls are created in a dialog.
4474 // This is the easiest since a dialog is created with its original

4476 //
4477 // 2) The controls are direct children of a frame
4478 // In this instance the controls are actually children of the Frame's
4479 // client. During creation the frame's client resizes several times
4480 // during creation of the status bar and toolbars. The CFrame class
4481 // will take care of this using its AlterChildPos proc.
4482 //

4484 // a frame.
4485 // The panel may be one of many, in which case the same treatment

4488 // the frame and as such, when a frame has only one child, the child is
4489 // expanded to fit the entire client area of the frame. Because the
4490 // controls are created BEFORE this occurs their positions are totally
4491 // whacked and any call to WinQueryWindowPos will return invalid
4492 // coordinates. So for this situation we have to compare the size of
4493 // the panel at control creation time with that of the frame client. If
4494 // they are the same we can use the standard Y position equation. If
4495 // not, then we must use the Frame Client's dimensions to position them
