CRichEditCtrl in CDockablePane

Question

CRichEditCtrl in CDockablePane

Flaviu_ 1,091

I intend to put a CRichEditCtrl in a CDockablePane, and I succeeded some way, but not completelly: I can write text in this embeeded CRichEditCtrl, but I have not formating and I noticed something strange: the keyboard shortcuts is functional only if I keep Shift key down. For instance, if I want to 'Paste' something, instead of Ctrl+V, I need to press Ctrl+Shift+V, and so on.

I attached here a sample project that reveal the problem.

Here is the code for creating CRichEditCtrl inside of CDockablePane:

int CClassView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
 if (CDockablePane::OnCreate(lpCreateStruct) == -1)
 return -1;

 CRect rectDummy;
 rectDummy.SetRectEmpty();
 constexpr DWORD dwStyle = WS_VISIBLE | WS_HSCROLL | WS_VSCROLL | ES_MULTILINE | ES_AUTOVSCROLL | ES_WANTRETURN;
 if (! m_wndRichEditCtrl.Create(dwStyle, rectDummy, this, IDC_RICHEDIT_QUERY))
 {
 TRACE(_T("Failed to create rich edit control\n"));
 return -1;      // fail to create
 }

 m_wndRichEditCtrl.PostMessage(EM_SETEVENTMASK, 0, ENM_MOUSEEVENTS | ENM_SCROLLEVENTS | ENM_KEYEVENTS);

 return 0;
}

And something strange: if I copy something from, let say, Visual Studio, and I paste it here, the formating is not kept, as I said ... why ?

Sorry, I forgot to attach the sample project, I'll do it in few moments.

Hi,

As far as I'm concerned you could try to overload BOOL PreTranslateMessage (MSG* pMsg)

Here is my code:

BOOL CClassView::PreTranslateMessage(MSG* pMsg)  
{  
	// TODO: Add your specialized code here and/or call the base class  
  
	if (pMsg->message == WM_KEYDOWN)  
	{  
		int nKey = pMsg->wParam;  
		if ((nKey == 'C' || nKey == 'X'  
			|| nKey == 'V') &&  
			(::GetKeyState(VK_CONTROL) & 0x8000))  
		{  
			::TranslateMessage(pMsg);  
			::DispatchMessage(pMsg);  
			return(TRUE);  
		}  
	}  
	  
  
  
  
	return CDockablePane::PreTranslateMessage(pMsg);  
}

Best Regards,

Jeanine

Answer 1

How is proper way to route the MFC commands from CEditView to CMyPanel ? Is the PreTranslateMessage the correct way ?

As far as I know, this handler should be avoided ...

P.S.
Even if I use this handler, how can route all MFC messages ?

The documentation notes the general principles; I'm rather rusty in such areas these days, but it's usually best to go with the flow, so rather than subvert the flow, I'd probably try to ensure that whatever I'm doing fitted into the general scheme by trying to have the panel with your rich edit control be the active view. See this also.

Thank you a lot for your guidelines. I have tried as you said, but I guess I am failed:

BOOL CBBBView::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{
    // TODO: Add your specialized code here and/or call the base class

    CMainFrame* pFrame = static_cast<CMainFrame*>(AfxGetMainWnd());

    if (pFrame->GetClassView() &&
        pFrame->GetClassView()->OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
        return TRUE;

    return CEditView::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
}

but the messages are still goes through CView, not on my Panel. It never returns TRUE this handler. I'll attach the sample, in few minutes.

New version of BBB original project, but which has OnCmdMsg handler in CView.

P.S. Just tell me if the link/project is not available.

And I have tried this approach inside of CMainFrame:

BOOL CMainFrame::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{
    // TODO: Add your specialized code here and/or call the base class

    TRACE("%d|%d\n", nID, nCode);
    if (m_wndClassView &&   m_wndClassView.OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
    {
        TRACE("\n========================================\n");
        return TRUE;
    }

    return CMDIFrameWndEx::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
}

The same, is not working.

P.S> Maybe because there are two panels in CMainFrame and don't know through which of them to routing ...

Try putting the OnCmdMsg handler in your CChildFrame class rather than CMainFrame. I think the MDI frame window is bypassing the top level frame window handler in your situation.

Did you not try your code in the child frame class?

Yes, I tried that code inside CChildFrame but didn't worked. Seem that overloading PreTranslateMessage in CMyPanel goes pretty well. Yes, I need to refine that code, but for the moment it goes.

P.S. Thank you I lot for any hint, helped me to solve the issue !!

David Lowndes 4,731

That's odd, it routed the command messages through for me; I could handle the OnEditPaste handler in CClassView in my modified version of your sample:

void CClassView::OnEditPaste()
{
    m_wndRichEditCtrl.Paste();
}

BOOL CChildFrame::OnCmdMsg( UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo )
{
    CMainFrame * pfw = static_cast<CMainFrame * >(AfxGetMainWnd());
    if ( pfw->MyCmdMsg( nID, nCode, pExtra, pHandlerInfo ) )
    {
        return TRUE;
    }

    return CMDIChildWndEx::OnCmdMsg( nID, nCode, pExtra, pHandlerInfo );
}

BOOL CMainFrame::MyCmdMsg( UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo )
{
    if ( m_wndClassView.GetSafeHwnd() && m_wndClassView.IsVisible() )
    {
        if ( m_wndClassView.OnCmdMsg( nID, nCode, pExtra, pHandlerInfo ) )
        {
            return TRUE;
        }
    }

    return FALSE;
}

That's interesting, I guess I didn't map OnPaste command, but I am not sure though. I'll take a look and I'll give you feedback.

Thank you a lot !!!

Yes, you had right, overriding OnCmdMsg in CChildFrame solved the problem. Thank you a lot David !

Great, thanks for confirming.

Answer 2

Flaviu_ 1,091

Yes, you are right, I need to re-route those commands from the main view to the panel, when the focus is inside of this panel.

Hi

Ctrl+V also works for me with your project. I suggest you could try to check if the shortcut key of Edit.Paste is Ctrl+V. In your case, it might be Ctrl+Shift+V. Try changing it to Ctrl + V.

Have you tried on CDockable pane to do that ? Randomly, I derived CView from CEditView, but it is about CDockablePane which has a CRichEditCtrl memeber stretched on whole pane, see the code above.
David Lowndes 4,731 Reputation points

OK, with that clarified I can reproduce what you say.

If I re-assign the application's Ctrl+V accelerator to something else, then Ctrl+V works in your child rich edit control, so presumably you're just falling foul of MFCs command routing in that example.

Answer 4

David Lowndes 4,731

Plain Ctrl+V works for me with your project.

As for why you're not seeing rich text pasted, you appear to have created the project with a plain edit view base, rather than CRichEditView - creating a new project using that as the view base allows pasting RTF for me.

Flaviu_ 1,091

It is about CClassView which is derived from CDockablePane. It's about a pane from that test application, not CView from framework:

class CClassView : public CDockablePane  
{  
public:  
	CClassView() noexcept;  
	virtual ~CClassView();  
  
	void AdjustLayout();  
	CRichEditCtrl* GetRichEditCtrl() { return &m_wndRichEditCtrl; }  
  
protected:  
	CRichEditCtrl m_wndRichEditCtrl;  
  
// Overrides  
public:  
  
protected:  
	afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);  
	afx_msg void OnSize(UINT nType, int cx, int cy);  
	afx_msg void OnClose();  
	afx_msg void OnSetFocus(CWnd* pOldWnd);  
	afx_msg void OnContextMenu(CWnd* pWnd, CPoint point);  
	DECLARE_MESSAGE_MAP()  
};
