Dear Support,

I would like to add Undo & Redo buttons like in visual studio - with a drop list and an automatic selection on hover. Is it possible in Prof-UIS? Do you have any sample?

Thanks,

Ron.

The CExtBarUndoRedoButton toolbar button implements an undo-redo button exactly like your described. It’s well integrated with the Prof-UIS customization subsystem for toolbars and menus (CExtCustomizeSite) and with ribbon controls (CExtRibbonBar, CExtRibbonPage). The BitmapEditor demonstrates how to use undo-redo buttons.

Dear Support,

I tried to follow the example in the bitmap editor, however I only need the undo/redo and not all the customization found there, so I narrowed it to this piece of code I added in OnCreate, but nothing happened to the button in my toolbar:

    CWinApp* pApp = ::AfxGetApp();
    g_CmdManager->ProfileSetup(pApp->m_pszProfileName, GetSafeHwnd());
    g_CmdManager->UpdateFromMenu(pApp->m_pszProfileName, IDR_MAINFRAME);
    g_CmdManager->UpdateFromToolBar(pApp->m_pszProfileName, IDR_TOOLBAR_EDIT_BIG);

    CExtCmdItem* pCmdItem = g_CmdManager->CmdGetPtr(pApp->m_pszProfileName, ID_EDIT_UNDO );
    pCmdItem->m_nLParamUserData = (LPARAM)pCmdItem->m_nCmdID;
    pCmdItem->StateSetUndoRedo();
    pCmdItem->StateSetSeparatedDD();

What other minimal steps I need to take to have the undo-redo? I’m still before adding the content to the drop-down, just to see the arrow next to the button, and for it to drop the drop-down...

Thanks,

Ron

The BitmapEditor sample application demonstrates the CExtImageEditWnd control features. It performs image editing and supports undo-redo. The sample app uses customizable toolbars and menus and we made the ID_EDIT_UNDO and ID_EDIT_REDO commands in toolbars and menus working like undo-redo popup list boxes. The following part of the CMainFrame::OnCreate() method just marks these commands as list boxes:

CExtCmdItem * pCmdItem =
            g_CmdManager->CmdGetPtr( pApp->m_pszProfileName, ID_EDIT_UNDO );
      ASSERT( pCmdItem != NULL );
      pCmdItem->m_nLParamUserData = (LPARAM)pCmdItem->m_nCmdID;
#if (!defined __EXT_MFC_NO_CUSTOMIZE)
      pCmdItem->StateSetUndoRedo();
      pCmdItem->StateSetSeparatedDD();
#endif // (!defined __EXT_MFC_NO_CUSTOMIZE)

      pCmdItem =
            g_CmdManager->CmdGetPtr( pApp->m_pszProfileName, ID_EDIT_REDO );
      ASSERT( pCmdItem != NULL );
      pCmdItem->m_nLParamUserData = (LPARAM)pCmdItem->m_nCmdID;
#if (!defined __EXT_MFC_NO_CUSTOMIZE)
      pCmdItem->StateSetUndoRedo();
      pCmdItem->StateSetSeparatedDD();
#endif // (!defined __EXT_MFC_NO_CUSTOMIZE)

The following virtual methods are initializing list box content, measuring popup list box size, handling the item selection and provide list box caption:

CMainFrame::OnPopupListBoxInitContent()
CMainFrame::OnPopupListBoxMeasureTrackSize()
CMainFrame::OnPopupListBoxSelEndOK()
CMainFrame::OnPopupUndoRedoFormatCaption()

You should implement the same methods in your project.
