window tracking activation fixes
File size: 28.3 KB
Line 
1/*
2 * Window tracking related functions.
3 *
4 * Copyright 2001 Sander van Leeuwen
5 *
6 * Changes from Wine code: (20011004)
7 * - Only draw changed track frame instead of clearing the old one and
8 * drawing the new one (less flickering)
9 * - Send WM_MOVING when moving a window (not done in Wine)
10 * - Send WM_SIZING only when sizing a window
11 * - Fixed handling of rectangles changed by WM_SIZING/MOVING
12 *
13 * Based on Wine code: (dlls\x11drv\winpos.c)
