I want to dynamically modify the icon of the a split  button in my program, is there anyway I could do it.

 

For example, in the toolbar, I created a split button is named "Width". Clicking on its drop-down button, a list a width will show and user could select one out of the list.  After user's selection, I want the "Width" button to display a stroke with the current selected width, how to do that?

 

 

I have checked the tear-off  Popup example, however, I found that the CXTPControlPopupColor class is built-in class and after user select the color, the SetColor() function could be used to update the color.  But  there is no CXTPControlPopupWidth class. Without this class, how can I get this job done manually?

 

 

Hello,

Add update handle for button and

 

 CXTPControl* pPopup = CXTPControl::FromUI(pCmdUI);
 if (pPopup)
 {
  pPopup->SetIconId(m_iconId);
 }

 

 

But before that, XTPImageManager()->SetIcons() should be called.
