Hosting the System.Windows.Forms.MonthCalendar control

Introduction

This example provides a simple application that hosts the MonthCalendar winforms control from a Qt application.

The .Net MonthCalendar running in a Qt application.

Hosting the .Net MonthCalendar control.

After initialization of QApplication, but before the instantiation of the QtControlHost the application must make sure that the QtWinForms is initialized properly by calling QtWinFormsUtils::initWindowsFormsForQt():

 #include <qtwinforms.h>
 #include "mainwindow.h"
 #include <QApplication>

 int main(int argc, char *argv[])
 {
     QApplication app(argc, argv);

     QtWinFormsUtils::initWindowsFormsForQt();

     MainWindow window;
     window.show();

     return app.exec();
 }

Instantiation of the QtControlHost is done in the constructor of the MainWindow class:

 MainWindow::MainWindow()
 {
     QVBoxLayout *vl = new QVBoxLayout();

     calendar = gcnew System::Windows::Forms::MonthCalendar();
     calendar->ShowToday = false;
     calendar->ShowTodayCircle = false;
     calendarHost = new QtControlHost(calendar, this);
     ...
 }

In this example we also modify some properties of the hosted control before we pass it in to the constructor of the QtControlHost.
