Hi!

I have added a listbox to the ribbonbar, but there are some issues with it. When I switch to another tab, the listbox stays on the top of other controls, where it should dissapear. The ListBox is not drop-down. It is there at all times. It is also the only control in a group, and for the time, the only one in the tab.

Any ideas? Or a sample how a ListBox can be used in a Ribbon?

Thanks,

Bojan

Hi,

I very recommend you use Galleries instead.

Sorry, can't do it.
The problem is that I already have a very complicated control inherited from CListCtrl, that allready has all functionality I need. I created my own class CMyXTPControlListBox : public CXTPControl, that has my CMyListCtrl control instead of the original one.
Maybe you could shortly explain me the mechanism inside a control that hides it when a tab is switched? That would be great!

Thanks!

Sincerely,

Bojan Hrnkas

check sources of CXTPControlCustom.

You need override

void CXTPControlCustom::SetHideFlags(DWORD dwFlags)

and

void CXTPControlCustom::SetRect(CRect rcControl)

I have. This is my code:

Code:

void CMyXTPControlListBox::SetRect(CRect rcControl)
{
    ASSERT_VALID(this);

    if (m_rcControl == rcControl && m_pListBox->GetParent() == m_pParent)
    {
        return;
    }

    m_rcControl = rcControl;

    m_pListBox->EnableWindow(GetEnabled());

    m_pListBox->ModifyStyle(WS_POPUP, WS_CHILD);
    m_pListBox->SetParent(m_pParent);
    m_pListBox->MoveWindow(rcControl);
    m_pListBox->SetWindowPos(0, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_NOACTIVATE | (!IsVisible() ? SWP_HIDEWINDOW : SWP_SHOWWINDOW));
}

void CMyXTPControlListBox::SetHideFlags(DWORD dwFlags) {
    m_dwHideFlags = dwFlags;
    if (m_dwHideFlags != xtpNoHide)
    {
        if (m_pListBox && m_pListBox->GetSafeHwnd())
            m_pListBox->SetWindowPos(0, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_NOACTIVATE | SWP_HIDEWINDOW);
        DelayLayoutParent();
    }
    else
    {
        if (m_pListBox && m_pListBox->GetSafeHwnd())
            m_pListBox->SetWindowPos(0, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_NOACTIVATE | SWP_SHOWWINDOW);
        DelayLayoutParent();
    }
}

The code for hiding is executed properly, but the control just won't go away.

Solved the problem by using MoveWindow(CRect(0,0,0,0)) when the control should be hidden. Not the perfect solution, but it works.

Thanks for your time, Oleg! I appriciate it!
