Drawing not updated after adding Docking Pane

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,

I have a problem using Docking Pane. I'm developing a simple MFC application to draw objects in OnDraw function. However, after adding the docking pane, I cannot see my drawing (Pic 1). Instead, if i 'auto-hide' my pane, then i can see what have been drawn (Pic 2). Strangely, I can also update my drawing if i minimise and then maximise back my application.

Furthuremore, the place where the dock was before turns black if both of the pane autohide. (Pic 3). 

In OnDraw(CDC* ipDC), i use BitBlt and set the OnEraseBkgnd(CDC* pDC) to return TRUE.

Thanks in advance,

Cheers,
F.Abhar

	sounds like you haven't set the style WS_CLIPSIBLINGS on the main client area.

	Hi, thanks for the replies, I follow instructions in Codejock's Tutorial (Toolkit Pro User Guide) on adding docking pane to my application. First, I create the bars in OnCreate function: // Create docking panes. CXTPDockingPane* pwndPane1 = m_paneManager.CreatePane( IDR_PANE_OPTIONS, CRect(0, 0,200, 120), dockLeftOf); CXTPDockingPane* pwndPane2 = m_paneManager.CreatePane( IDR_PANE_PROPERTIES, CRect(0, 0,200, 120), dockBottomOf, pwndPane1) Then I added icons for the panes: int nIDIcons[] = {IDR_PANE_OPTIONS, IDR_PANE_PROPERTIES}; m_paneManager.SetIcons(IDB_BITMAP_ICONS, nIDIcons, _countof(nIDIcons), RGB(0, 255, 0)); I disabled the code to attach CWnd derived class (OnDockingPaneNotify) since it doesn't have any difference after I enabling it before. Am I missing something? I also changed my MainFrm derived class to `CXTPFrameWnd` since I would change my application interface later. Thanks in advanced. Cheers, F.Abhar.
