C++ – MFC Control in a Qt Tab Widget

cmfcqtqt-mfc-migration

I'm working on a project that is using the Qt/MFC Migration Framework and I'm trying to reuse some existing MFC controls inside of a Qt dialog.

Does anyone know if it is possible to insert an MFC control (CDialog or CWnd) inside of a QTabWidget. Right now we're doing the opposite, we have an MFC dialog with a tab control which is populated with a mix of MFC tabs (CDialog) and Qt tabs (QWinWidget). However, this approach is giving me a headache because the QWinWidget controls are not properly being drawn nor are they receiving focus or keyboard input correctly. I am hoping that using a Qt dialog with a QTabWidget will work better than this approach.

Seeing as you use QWinWidget, you must have come cross QWinHost? Simply use QWinHost as the pages for a QTabWidget:

HWND w = ...;
QTabWidget * tw = new QTabWidget;
QWinHost * wh = new QWinHost;
wh->setWindow( w );
tw->addTab( tr("Page with Windows Control"), wh );

C++ – QWinWidget Inside MFC Dialog Not Repainting or Responding to Tab/Arrow keys

I have fixed the keyboard input issue. The QWinWidget class needed some changes:

in the QWinWidget::init method, the WS_TABSTOP must be added to the window style:

SetWindowLong(winId(), GWL_STYLE, WS_CHILD | WS_CLIPCHILDREN | WS_CLIPSIBLINGS | WS_TABSTOP);

Also, the QWinWidget::winEvent method needs to respond to the WM_GETDLGCODE to let Windows know that it is interested in receiving key/tab inputs. I had to add this if block:

if(msg->message == WM_GETDLGCODE)
{
   *result = DLGC_WANTARROWS | DLGC_WANTTAB;
   return(true);
}

I am still working on getting the widget to paint properly.

C++ – MFC: How todentfy if Dialog was created using CPropertySheet or CTabCtrl

There are 2 classes derived from CPropertyPage, which is always used with CPropertySheet. No wonder there is no CTabCtrl. I'd like to explain in detail if you email me the code.
