Last change on this file since 87 was 75, checked in by dmik, 20 years ago

Added the PWO_TopLevel flag for qt_WinProcessWindowObstacles(): it tells to include top-level windows (children of the desktop) to the set of clipped out windows, which is necessary when moving ot scrolling windows (copies of parts of overlying top-level windows were left on the screen).
