|
* NOTES
|
|
*
|
|
* This code was audited for completeness against the documented features
|
|
* of Comctl32.dll version 6.0 on Sep. 18, 2004, by Robert Shearman.
|
|
*
|
|
* Unless otherwise noted, we believe this code to be complete, as per
|
|
* the specification mentioned above.
|
|
* If you discover missing features or bugs please note them below.
|
|
*
|
|
* TODO:
|
|
* Implement repetitive button press.
|
|
* Adjust arrow size relative to size of button.
|
|
* Allow border size changes.
|
|
* Styles:
|
|
* PGS_DRAGNDROP
|
|
* Notifications:
|
|
* PGN_HOTITEMCHANGE
|
|
* Messages:
|
|
* WM_PRINT and/or WM_PRINTCLIENT
|
|
*
|
|
* TESTING:
|
|
* Tested primarily with the controlspy Pager application.
|

|
|
*
|
|
* IMPLEMENTATION NOTES:
|
|
* This control uses WM_NCPAINT instead of WM_PAINT to paint itself
|
|
* as we need to scroll a child window. In order to do this we move
|
|
* the child window in the control's client area, using the clipping
|
|
* region that is automatically set around the client area. As the
|
|
* entire client area now consists of the child window, we must
|
|
* allocate space (WM_NCCALCSIZE) for the buttons and draw them as
|
|
* a non-client area (WM_NCPAINT).
