    Posted: 25 January 2007 at 3:50pm
I am trying to implement the Xtreme DockingPane library into a project that was previously using only Xtreme Toolkit 4.1.  Several of the windows were derived from CXTDockWindow and now I'm not sure how to get these CXTDockWindow based classes to work with the DockingPane library (to support tear away tabs).
 
I have tried changing the base class of these windows to CXTControlBar, but without success.  Is this necessary?  If not, should I use CWnd as the base class or some other class? 
 
Any help or suggestions or sample code is greatly appreciated.
 
Thanks...

I changed the base classes from CXTDockWindow to CWnd and after deleting some registry keys (for the layout?), all of the windows are shown in docking panes.  The CWnd based GUI windows are not being updated though.  I can undock one of those docked panes, but the pane shows undocked and undocked.  It appears that a redraw is not occuring for some reason.
 
Any ideas?

Hi,

 
Attach MainFrm.cpp to show what you do.

Problem in
LRESULT CMainFrame::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam)
{
 if (wParam == XTP_DPN_SHOWWINDOW)
 {
  // get a pointer to the docking pane being shown.
  CXTPDockingPane* pPane = (CXTPDockingPane*)lParam;
  if (!pPane->IsValid())
  {
   CWnd* pWnd = NULL;
   int nPaneID = pPane->GetID();
   if (m_mapPanes.Lookup(nPaneID, pWnd))
   {
    pPane->Attach(pWnd);
   }
  }
 }
 return TRUE; // handled
}
 
 
Don't return TRUE always.  Change it to
 
 
LRESULT CMainFrame::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam)
{
 if (wParam == XTP_DPN_SHOWWINDOW)
 {
  [code]
   return TRUE; // handled
}
  return FALSE;
}

I made the change and unfortunately, no difference.  The 3 panes and associated windows created via the CreatePane method of my class where I am using the RUNTIME_CLASS macro, update and resize correctly.
 
The 3 panes created using the DockingPaneManager's CreatePane method still do not get updated correctly and are either not shown (transparent backgrounds) or they display and then do not get repainted when the pane is detached or resized.

I also noticed that if I use class names in the Create call that the windows initially paint, but I am unable to update the windows.
 
For example, changing this:

m_pWndOutputPane = GetDockingPaneManager()->CreatePane(IDW_OUTPUTBAR, CRect(0, 0, 200, 120), dockBottomOf);

m_wndOutputBar.Create(NULL, "Output", WS_CHILD | WS_VISIBLE, CRect(0, 0, 200, 120), this, IDW_OUTPUTBAR, NULL);

m_pWndOutputPane->Attach(&m_wndOutputBar);

To this:

m_pWndOutputPane = GetDockingPaneManager()->CreatePane(IDW_OUTPUTBAR, CRect(0, 0, 200, 120), dockBottomOf);

m_wndOutputBar.Create("COutputBar", "Output", WS_CHILD | WS_VISIBLE, CRect(0, 0, 200, 120), this, IDW_OUTPUTBAR, NULL);

m_pWndOutputPane->Attach(&m_wndOutputBar);

Hi,
Can you attach whole application to debug it?

Unfortunately I cannot attach the files for debugging.  There are too many dependencies on third party controls and libraries...

For one of the problematic windows, if I change this:

m_wndOutputBar.Create(NULL, "Output", WS_CHILD | WS_VISIBLE, CRect(0, 0, 200, 120), this, IDW_OUTPUTBAR, NULL);

to this:

WNDCLASS wndcls;
memset(&wndcls, 0, sizeof(WNDCLASS));   
wndcls.style = CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW;
wndcls.lpfnWndProc = ::DefWindowProc;
wndcls.hInstance = AfxGetInstanceHandle();
wndcls.hIcon = NULL;
wndcls.hCursor = NULL;
wndcls.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1);
wndcls.lpszMenuName = NULL;
wndcls.lpszClassName = _T("COutputBar");
if(!AfxRegisterClass(&wndcls))
{
  TRACE("Class Registration Failed\n");
}
 
m_wndOutputBar.Create("COutputBar", "Output", WS_CHILD | WS_VISIBLE, CRect(0, 0, 200, 120), this, IDW_OUTPUTBAR, NULL);
 
Doing this, the window now gets painted, but none of the child windows get drawn.  The COutputBar class was originally derived from the CXTDockWindow class and was changed to derive from the CWnd base class. 
 
The COutputBar class we are using is the same class as that used in the GUI_VisualStudio6 example provided with the Xtreme Toolkit v4.1.
 
Thanks again...

Hi,

Create with Wizard new project, copy you code regarding COutputBar and try to reproduce it. If you will attach sample here.
 
Without your code there is no way to say what you do wrong.
