Hi,
I would like to prevent my controlbar to be redocked using a single flag as m_bLockBars. The idea is to place window for our needs and then we lock the interface to be sure they still keep their position. I’ve tried to ovveride the _DraggingStart method but it didn’t work. What should I do?

Tanks

To lock a control bar, you need to override two virtual methods of the CExtControlBar, CExtToolControlBar, or CExtMenuControlBar class: _DraggingStart() and ToggleDocking(). In both methods, simply do not invoke the parent class methods.

Tanks to your reply. It works but not when my control bars are tabulated. It looks like if any CExtControlBar classes are transformed to CExtDynTabControlBar and then my overriden methods aren’t called. What should I do?

The control bar algorithms create tabbed bar container windows dynamically during drag-and-drop or when you load the control bar’s state. The tabbed container is also a resizable control bar. It is a CExtDynTabControlBar window in case of simple control bars. If you want to use your CExtDynTabControlBar-classes, you need ti handle the CExtControlBar::g_nMsgCreateTabbedBar registered windows message in your main frame class:

ON_REGISTERED_MESSAGE( CExtControlBar::g_nMsgCreateTabbedBar, OnMsgCreateTabbedBar )
 
LRESULT CMainFrame::OnMsgCreateTabbedBar( WPARAM wParam, LPARAM )
{
CExtDynTabControlBar ** ppDynTabBar =
        reinterpret_cast < CExtDynTabControlBar ** > ( wParam );
    (*ppDynTabBar) = new C_YOUR_CExtDynTabControlBar_DERIVED_CLASS;
}

Of course, your tabbed bar class may implement any kind of custom layout and/or behavior you need.

In case of dynamic resizable control bars the tabbed container is a CExtDynamicTabbedControlBar class or derived from it and you should not handle the CExtControlBar::g_nMsgCreateTabbedBar registered windows message. Instead, override the CExtDynamicBarSite::OnDbsCreateTabbedBarInstance() virtual method:

CExtDynamicTabbedControlBar * CExtDynamicBarSite::OnDbsCreateTabbedBarInstance() const
{
    ASSERT( this != NULL );
CExtDynamicTabbedControlBar * pBar =
        new C_YOUR_CExtDynamicTabbedControlBar_DERIVED_CLASS;
    return pBar;
}
