* ComboBoxEx control
|
|
*
|
|
* Copyright 1998, 1999 Eric Kohl
|
|
*
|
|
* NOTES
|
|
* This is just a dummy control. An author is needed! Any volunteers?
|
|
* I will only improve this control once in a while.
|
|
* Eric <ekohl@abo.rhein-zeitung.de>
|
|
*
|
|
* TODO:
|
|
* - All messages.
|
|
* - All notifications.
|
|
*
|
|
* FIXME:
|
|
* - should include "combo.h"
|
|
|
|
* Changes Guy Albertelli <galberte@neo.lrun.com>
|
|
* 1. Implemented message CB_SETITEMHEIGHT
|
|
* 2. Implemented message WM_WINDOWPOSCHANGING
|
|
* 3. Implemented message WM_MEASUREITEM
|
|
* 4. Add code to WM_CREATE processing to set font of COMBOBOX and
|
|
* issue the CB_SETITEMHEIGHT to start the correct sizing process.
|
|
* The above 4 changes allow the window rect for the comboboxex
|
|
* to be set properly, which in turn allows the height of the
|
|
* rebar control it *may* be imbeded in to be correct.
|
|
* 5. Rewrite CBEM_INSERTITEMA to save the information.
|
|
* 6. Implemented message WM_DRAWITEM. The code will handle images
|
|
* but not "overlays" yet.
|
|
* 7. Fixed code in CBEM_SETIMAGELIST to resize control.
|
|
* 8. Add debugging code.
|
|
*
|
|
* Test vehicals were the ControlSpy modules (rebar.exe and comboboxex.exe)
