Hello.

I have a ToolBar with a resource of 3 images. I need to change these images according to the actions of the user. I mean, one of the images is a "Play" image. I need to change that image for other in grayscale showing that there is no any playing available, for example when the user selects a non playable item of a list.

I can´t find out the way to make this as I don´t understand very well the tasks that CXTPCommandBars, CXTPCommandBar, CXTPImageManager and CXTPPaintManager develope.

It seems to be an only object of CXTPCommandBars class that acts as a set of all existing CXTPCommandBar elements. I have tried with CXTPImageManager but it seems to deal only with icons and not with images.

In addition I have tried to use pIconsInfo->bUseDisableIcons but it does not work at all. The image remains as it was created.

I know this may be a rather obvious topic for many users, therefore some explanation of these elements would be very welcome.

Thanks in advance!

Best way it to set icon in update handler for command id:

void CSliderSampleView::OnUpdatePlayerPlay(CCmdUI* pCmdUI)
{
 CXTPControl* pControl = CXTPControl::FromUI(pCmdUI);
 
 if (pControl) 
 {
  pControl->SetIconId(!m_bPlay || m_bPause ? ID_PLAYER_PLAY : ID_PLAYER_PAUSE);
 } 
}
