7 * This is just a dummy control. An author is needed! Any volunteers?
8 * I will only improve this control once in a while.
9 * Eric <ekohl@abo.rhein-zeitung.de>
13 * - All notifications.
16 * - should include "combo.h"
18 * Changes Guy Albertelli <galberte@neo.lrun.com>
19 * 1. Implemented message CB_SETITEMHEIGHT
20 * 2. Implemented message WM_WINDOWPOSCHANGING
21 * 3. Implemented message WM_MEASUREITEM
22 * 4. Add code to WM_CREATE processing to set font of COMBOBOX and
23 * issue the CB_SETITEMHEIGHT to start the correct sizing process.
24 * The above 4 changes allow the window rect for the comboboxex
25 * to be set properly, which in turn allows the height of the
26 * rebar control it *may* be imbeded in to be correct.
27 * 5. Rewrite CBEM_INSERTITEMA to save the information.
28 * 6. Implemented message WM_DRAWITEM. The code will handle images
29 * but not "overlays" yet.
30 * 7. Fixed code in CBEM_SETIMAGELIST to resize control.
31 * 8. Add debugging code.
33 * Test vehicals were the ControlSpy modules (rebar.exe and comboboxex.exe)
