Protected Methods

Name Description
CMFCRibbonGallery::OnDrawPaletteIcon Called by the framework when a gallery icon is drawn.

Remarks

A gallery button behaves just like a regular menu button except that it displays a gallery when a user opens it. When you select an item in a gallery, the framework sends the WM_COMMAND message together with command ID of the button. When you handle the message, you should call CMFCRibbonGallery::GetLastSelectedItem to determine which item was selected from the gallery.

Example

The following example demonstrates how to use various methods in the CMFCRibbonGallery class to configure a CMFCRibbonGallery object. The example illustrates how to specify the number of items per row in the gallery, enable resizing of the menu panel, enable the side bar to the left of the pop-up menu, and display the ribbon gallery as a palette directly on the ribbon bar. This code snippet is part of the Draw Client sample.

CMFCRibbonGallery *pBtnStyles = new CMFCRibbonGallery(ID_OBJECT_STYLES, _T("Styles\nk"), 0, 0, IDB_STYLES, 40);
pBtnStyles->SetIconsInRow(7);
pBtnStyles->EnableMenuResize(TRUE, TRUE);
pBtnStyles->EnableMenuSideBar();
pBtnStyles->SetButtonMode(false);
pBtnStyles->RedrawIcons();
