Hi,

I was looking at this sample and I noticed that no scroll bars appeared for the TreeView when all root level items were expanded even though in the code they are defined at .Create:

    if( !m_wndDockedCtrlTree.Create(
            WS_CHILD|WS_VISIBLE|WS_VSCROLL|WS_HSCROLL
            |TVS_HASBUTTONS|TVS_HASLINES|TVS_LINESATROOT
            |TVS_INFOTIP|TVS_DISABLEDRAGDROP
            |TVS_SINGLEEXPAND|TVS_SHOWSELALWAYS
            ,
            CRect(0,0,0,0),
            &m_wndResizableBarTree,
            m_wndResizableBarTree.GetDlgCtrlID()
            )
        )


Any ideas?

Jamie.

I use very simple way to enabling flat scrollbars
in any control located inside of extControlBar:

1. Download the CoolScrollLibrary from www.catch22.uk.net (thanks for J.Brown james@catch22.uk.net)

2. Compile it and insert into your project
3. In .h file instead of
CExtWRB<CExtWFF<CMtDeviceTreeCtrl>> m_wndDockedCtrlTree;
use
CTreeCtrl m_wndDockedCtrlTree;

4. in .cpp
if( !m_wndDockedCtrlTree.Create(...))
{
...
}
InitializeCoolSB(hwndCtrl);
CoolSB_SetStyle(hwndCtrl, SB_BOTH, CSBS_HOTTRACKED);
...
...
5. In app.cpp file:
BOOL CYourApp::OnInitInstance()
{
...
CoolSB_InitializeApp();
CMainFrame* pFrame = new CMainFrame;
....
}

int CYourApp::ExitInstance ()
{
CoolSB_UninitializeApp();
return CWinApp::ExitInstance ();
}

Thas all!

Hi James,

you can change it in MainFrm.h:
//CExtWRB<CExtWFF<CTreeCtrl>> m_wndDockedCtrlTree;
CTreeCtrl m_wndDockedCtrlTree;

And it is worked ,-)
