Is there a sample that illustrates how to handle a toolbar button with a submenu? 

What I would like to have is a toolbar button with a drop-down menu.

Thanks for your help

Dear Finn,

You can find a toolbar button with a pop-up menu in the DRAWCLI sample application. Here is how to implement it.


First of all, add a menu resource with one root pop-up item (its text is unimportant). This menu will be used by the toolbar button. Please register this menu in the command manager by calling g_CmdManager->UpdateFromMenu() (similar to how you do this for the menu bar’s menu). After that, put the following lines after the code responsible for creating the toolbar:

INT nBtnIdx =
    m_wndToolBar.CommandToIndex(
        ID_BUTTON_FOR_MENU
        );
ASSERT( nBtnIdx >= 0 );
CMenu _menu;
VERIFY(
    _menu.LoadMenu(
        IDR_MENU_RESOURCE_FOR_BUTTON
        )
    );
VERIFY(
    m_wndToolBar.SetButtonMenu(
        nBtnIdx,
        _menu.Detach()
        )
    );

If you want the button face to be split into two parts (a drop-down button), invoke the following methods after the button’s menu is attached:

CExtBarButton * pTBB =
    m_wndToolBar.GetButton( nBtnIdx );
ASSERT_VALID( pTBB );
pTBB->SetSeparatedDropDown();

If you want your button to look in the vertically docked toolbar the same as it looks in the horizontally docked toolbar, call

pTBB->SetNoRotateVerticalLayout();

For the button with a drop-down arrow (a drop-down button), you may need to set the initially selected command:

pTBB->SetAutoChangeID();
pTBB->SetCmdID(ID_INITIALLY_SELECTED_COMMAND,true); 

It works nicely.  Many thanks.
