How to make CXTHeaderCtr::DrawItem() be called?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a class derived from MFC class CHeaderCtrl with DrawItem() function overrided. 
I set its HDI_ITEM variable hdi.fmt = HDF_CENTER | HDF_STRING | HDF_OWNERDRAW; 
My DrawItem() function works before I changed to CXTHeaderCtrl.
Now I use CXTHeaderCtrl instead of CHeaderCtrl, and then my DrawItem() function is not being called anymore.
Can anybody tell me that how I can make DrawItem() being called when using CXTHeaderCtrl? 
Thanks in advance.

	Hello, Its not called from CXTHeaderCtrl. to support custom themes CXTHeaderCtrl catch WM_PAINT and draw all header manually. See XTHeaderCtrlTheme.cpp file - you can derive from CXTHeaderCtrlTheme and override some methods.

	I made an override function of CXTHeaderCtrlTheme::DrawHeader(), now it works fine. But there is a problem, when I right click on my header column, it always pop up a menu, it has "Sort Ascending", "Sort Descending" and "Alignment" with submenus, even if I did not create this menu. I want to get rid of this popup menu, and put my popup menu there, how can I get rid of this menu? Thanks in advance.
