Dynamically change the toolbar button icon

In this example, the dynamically changed toolbar button icon is stored in the toolbar resource whose ID is idr_toolbar_shell and can be used as a bitmap resource.

Cimagelist * m_imglist1;

M_imglist1 = (m_wndtoolbar.gettoolbarctrl (). getimagelist ();

Int A = m_imglist1-> getimagecount ();

Cbitmap CBMP;

Bitmap BMP;

CBMP. loadbitmap (idr_toolbar_shell );

CBMP. getbitmap (& BMP );

M_imglist1-> Add (& CBMP, RGB (192,192,192 ));

(M_wndtoolbar.gettoolbarctrl (). setimagelist (m );

M_imglist1-> detach ();

M_imglist1 = NULL;

CBMP. deleteobject ();

The above Code adds bitmap in idr_toolbar_shell to the image list of m_wndtoolbar, which can also be implemented through other methods.

Next, you can dynamically change the icon of a button. For example, change the icon ID id_menuitem32780 to the second icon in idr_toolbar_shell:

M_wndtoolbar.setbuttoninfo (m_wndtoolbar.commandtoindex (id_menuitem32780), id_menuitem32780, tbbs_button, A + 1 );
