I have an MDI application where all views are held by a CXTPTabClientWnd variable. In one of my form views I have a auto-hiding pane placed at the top of the frame. If I attach it, the whole view gets repainted incorrectly.

I have to minimize the window and then maximize it again to get back my controls in their original shape. I have a similar pane in a calendar view, but the calendar seems to understand that it should repaint itself.

I have tried this inside my docking notification handler:

if (wParam == XTP_DPN_ACTION)
{

    XTP_DOCKINGPANE_ACTION* pAction = (XTP_DOCKINGPANE_ACTION*)lParam;
    if (pAction->action == xtpPaneActionAttached)
        GetActiveView()->Invalidate();
}

I have also been playing with the WS_CLIPSIBLINGS and WS_CLIPCHILDREN styles, with no success. What is causing this redraw problem?

Please help!

The project found at the address below has three problems:

1) It paints incorrectly when the pane is attached (see attached screenshot).

2) The auto-resizing controls do not behave correctly when the window is being resized in certain ways (see attached screenshot).

3) I get a lot of warnings when compiling. Where should I turn these off (I do not always want to ignore C4244)?

If you have time, then I wonder another thing too:
How do I attach a CXTPToolBar to the left of a specific view? That is, it should only appear when, say CMyViewWithAMenu is active. There is no sample showing this, and I haven't been able to figure out how to accomplish it.

Thanks in advance!

ps.

About warning - use search in forum, or update sources to 10.3

About toolbar - see GUI_Whidbey sample.

Thank you very much! All problems solved! \o/

Though, I wonder about this call: SetScaleToFitSize(CSize(1, 1)).

All controls are placed correctly, but they can be resized to non-visible. How would you make the controls "grow, but not shrink more than (cx, cy)"? Is the only way to handle OnGetMinMaxInfo in the main frame?

Hi again!

I played a bit with the Whidbey sample, and it suffers the same problem I have encountered: The menus loaded elsewhere than in CMainFrame are not dockable and cannot be placed vertically.

// This is a modified version of the CPropertiesPane in the Whidbey sample

int CPropertiesPane::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CWnd::OnCreate(lpCreateStruct) == -1)
return -1;

...

}

What I want to do is to add a toolbar to the left, INSIDE ONE of my views. I do not want it to be visible in other views. Can it be done?
