Topic: Handling WM_ENTERMENULOOP and WM_EXITMENULOOP

In a normal MFC app (not using ToolkitPro) you can receive the WM_ENTERMENULOOP and WM_EXITMENULOOP messages through the CFrameWnd derived class. However, this does not appear to be the case with a ToolkitPro MFC app. Is there a way to receive these messages (ideally through the derived CFrameWnd class)?

Thanks

Hi,

No, CommandBars don't have such messages. What do you want implement in such handlers?

Ahh, so these messages are never generated. I'm developing an application that contains a 3D render window (using Direct3D) that is continously rendered to. However, I would like to pause the rendering when the user activates a menu (e.g. File). The standard way of handling this in a D3D app is to pause/unpause the drawing in response to the WM_ENTERMENULOOP and WM_EXITMENULOOP messages. Is there some analogous way of handling this with CommandBars?

Thanks again.

Hi,

If you have 10.3/10.4 here workaround:

class CMyCommandBars : public CXTPCommandBars
{
DECLARE_DYNCREATE(CMyCommandBars)
CMyCommandBars()
{
m_bTracking = FALSE;
}
void OnTrackingModeChanged(CXTPCommandBar* pCommandBar, int bMode)
{
CXTPCommandBars::OnTrackingModeChanged(pCommandBar, bMode);

  if (bMode && !m_bTracking)
  {
   m_bTracking = TRUE;
   GetSite()->SendMessage(WM_ENTERMENULOOP);
  }
  else if (!bMode && !GetMouseManager()->IsTrackedLock(0) && m_bTracking)
  {
   m_bTracking = FALSE;
   GetSite()->SendMessage(WM_EXITMENULOOP);
  }
}

BOOL m_bTracking;
};
IMPLEMENT_DYNCREATE(CMyCommandBars, CXTPCommandBars)

usage:

if (!InitCommandBars(RUNTIME_CLASS(CMyCommandBars)))
return -1;
