Hello,

I am using CExtTabWnd & CExtTabPageContainerWnd to display tabs.

I can handle click on a tab item by overriding "OnTabWndClickedItem" function.

I can handle click on "Close" and "Help buttons on the tab area of the page container by overriding OnTabWndClickedButton.

But I can’t find how to handle click (more precisely a right click) on a tab item in the tab list.

What I want is to display a popup menu when right clicking a tab item in this list (the same popup menu that I display when I right click the tab item with "OnTabWndClickedItem" function.

For example (see screenshot below), how can I handle a right click on the "TreeCtrl" item.

Thank you in advance for any help

You should handle the CExtPopupBaseWnd::g_nMsgTranslateMouseClickEvent registered message in your tab window class:

ON_REGISTERED_MESSAGE(
        CExtPopupBaseWnd::g_nMsgTranslateMouseClickEvent,
        OnMsgTranslateMouseClickEvent
        )

LRESULT CYourTabWnd::OnMsgTranslateMouseClickEvent(WPARAM wParam, LPARAM lParam)
{
    ASSERT_VALID( this ); wParam; lParam;
#ifdef _DEBUG
CExtPopupBaseWnd::TranslateMouseClickEventData_t * pData = (CExtPopupBaseWnd::TranslateMouseClickEventData_t*)wParam;
    ASSERT( pData != NULL );
    if( pData->m_nFlags == WM_LBUTTONDOWN )
        afxDump << "WM_LBUTTONDOWN\r\n";
    else
    if( pData->m_nFlags == WM_MBUTTONDOWN )
        afxDump << "WM_MBUTTONDOWN\r\n";
    else
    if( pData->m_nFlags == WM_RBUTTONDOWN )
        afxDump << "WM_RBUTTONDOWN\r\n";
#endif // _DEBUG
    return 0L;
}

Hello,

Indeed, overriding "OnMsgTranslateMouseClickEvent" in my tab window class allows me to catch right click events in the vertical list of tabs.

Now, can I know which tab item has been clicked (by getting its index for example)?

I saw the attribute m_point in the pData pointer, but I can’t figure how to get the index info (except dividing m_point.y by the height in pixels of a popup menu item ?).

Thank you in advance for any help

Menu items have an order of tab items. Menu item identifiers are computed as 0xffff plus tab item index. The CExtPopupMenuWnd::_HitTest() method allows you to hit test menu items. Please note menu items with zero command identifiers are separators.

Hello,

Thank you, but handling "ON_WM_RBUTTONDOWN" in my CExtTabWnd derivated class does not seem to work.

I do not enter in the function "OnRButtonDown((UINT nFlags, CPoint point)" when right clicking a tab item from the right vertical list of tabs (see screenshot below). This work only when i right click a tab item in the horizontal list.

I’m using version 2.64 of Prof-UIS.

Thank you in advance for any help

You should handle the WM_RBUTTONDOWN message in the tab window and perform tab item hit testing using the CExtTabWnd::ItemHitTest() method.
