22 * This code was audited for completeness against the documented features
23 * of Comctl32.dll version 6.0 on Sep. 18, 2004, by Robert Shearman.
25 * Unless otherwise noted, we believe this code to be complete, as per
26 * the specification mentioned above.
27 * If you discover missing features or bugs please note them below.
30 * Implement repetitive button press.
31 * Adjust arrow size relative to size of button.
32 * Allow border size changes.
38 * WM_PRINT and/or WM_PRINTCLIENT
41 * Tested primarily with the controlspy Pager application.
42 * Susan Farley (susan@codeweavers.com)
44 * IMPLEMENTATION NOTES:
45 * This control uses WM_NCPAINT instead of WM_PAINT to paint itself
46 * as we need to scroll a child window. In order to do this we move
47 * the child window in the control's client area, using the clipping
48 * region that is automatically set around the client area. As the
49 * entire client area now consists of the child window, we must
50 * allocate space (WM_NCCALCSIZE) for the buttons and draw them as
51 * a non-client area (WM_NCPAINT).
