Disable Close button (X) of a QDialog

[jpn]

That's MFC, not WinAPI...

#include <QtGui>
#ifdef Q_WS_WIN
#include <qt_windows.h>
#endif // Q_WS_WIN
 
int main(int argc, char *argv[])
{
	QApplication app(argc, argv);
	QWidget window;
 
#ifdef Q_WS_WIN
	HMENU menu = ::GetSystemMenu(window.winId(), FALSE);
	::DeleteMenu(menu, SC_CLOSE, MF_BYCOMMAND);
	::EnableMenuItem(menu, SC_CLOSE, MF_BYCOMMAND | MF_GRAYED);
	// or (removes the item in of system menu)
	// ::DeleteMenu(menu, SC_CLOSE, MF_BYCOMMAND);
#endif // Q_WS_WIN
 
	window.show();
	return app.exec();
}

#include <QtGui>

	window.show();
	return app.exec();
}
