Question

I’ve followed the steps from this question:
Higher color depth for MFC toolbar icons?

The code works. But I have another problem – any disabled buttons are just grey boxes.
Once they are enabled – they are exactly as they should be.

I suspect that the CToolBar doesn’t know how to grey out the supplied images – can anyone help?

thanks in advance.

Answer 1

CToolBar actually accepts up to three imagelists each to handle the normal, disabled and highlighted states of the button.

To accomplish what I need – just normal and disabled button states. I need two images. One with normal coloured icons and the other with greyed out icons.

Add the images as Bitmap resources to your project – amend and make note of the IDs

Create two imagelists and set them accordingly: (m_wndToolBar is the toolbar in my project)

CImageList imgListActive;
CImageList imgListDisabled;
/* Load your CImageLists */
m_wndToolBar.GetToolBarCtrl().SetImageList(&imgListActive);
m_wndToolBar.GetToolBarCtrl().SetDisabledImageList(&imgListDisabled);

To set the highlighted versions of the toolbar:

CImageList imgListHighlighted;
/* Load your CImageList */
m_wndToolBar.GetToolBarCtrl().SetHotImageList(&imgListHighlighted);

et voila!
