CXTPControlComboBox + Ribbon + ownerdraw prob

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

   I have a Ribbon based app.  I am trying to add a CXTPControlComboBox control that will be owner drawn.  It does not have the edit field.

I subclass the control.  I set the listbox style to (LBS_OWNERDRAWFIXED | LBS_HASSTRINGS) 

DrawEditText does gets called whether the style is set or not .

No matter which way the style is set, DrawItem and MeasureItem do not get called.  If the style is not set, the listbox will do its default draw.  If it is set, the background is filled but that is all.

I've looked at the custom themes example but I think the Ribbon may be causing the problem.

So I am stumped about how to proceed.

	OK, figured it out. when creating the CXTPControlComboBox its constructors default parameter is NULL. If this value is set to the CommandBars object, the control message reflection will work allowing ownerdraw to work. You can get the CommandBars object from the ribbonbar with GetCommandBars.
