CRichEditCtrl in CDockablePane

Question

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 ?

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);  
}

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.

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.

Answer 4

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.

Answer 5

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 ?
