I have an application with a ribbon UI. In this UI a button exists with a menu attached to it. What I wish to do is access the menu from the button handler to dynamically add and remove menu items.
void
CMyScrollView::OnMenuButtonHandler ()
{
// TODO: Add your command handler code here
CMFCRibbonBar *pRibbon = ((CMDIFrameWndEx*)GetTopLevelFrame())GetRibbonBar()
// Control ID_BTN_EDIT_MENU
// This where I would like to isolate and vary menu contents
}
In the CMainFRame window create a handler for the AFX_WM_ON_BEFORE_SHOW_RIBBON_ITEM_MENU message (ON_REGISTERED_MESSAGE).
Check for the Id of the button. Remove all previous items and add the one, you want.
LRESULT CMainFrame::OnBeforeShowRibbonItemMenu(WPARAM,LPARAM lp)
{
CMFCRibbonBaseElement *pElement = reinterpret_cast<CMFCRibbonBaseElement*>(lp);
// Try to get our menu button
switch (pElement->GetID())
{
case ID_RIBBON_DROPDOWN_BUTTON:
{
CMFCRibbonButton *pButton = DYNAMIC_DOWNCAST(CMFCRibbonButton, pElement);
if (pButton)
{
// MY_LIST copntains members with the ID and the text: m_uiCmdId, m_strTitle
const MY_LIST &list = ....;
if (list.size()!=0)
{
pButton->RemoveAllSubItems();
for (it = list.begin(); it!=list.end(); ++it)
pButton->AddSubItem(new CSomeKindOfRibbonButton(it->m_uiCmdId, it->m_strTitle));
}
}
...
