At a first pass, I tried code below as an  implementation for reveal. All
Qt's windows derive from QWidget, so we can use that as the argument to
reveal.  Calling processEvents() means  that no user interaction with the
window is possible, only viewing.

If user interaction is required then reveal needs to be slightly more
complex.

#include <qdialog.h>
#include <qapplication.h>
#include <iostream>

void reveal(QWidget* widget)
{
	// show the widget
	widget->show();
	// ask Qt to process the paint events so we can see the widget
	qApp->processEvents();
}


int main(int argc, char** argv)
{
	QApplication qApp(argc, argv);
	
	//create an empty dialog object
	QDialog* dialog = new QDialog();
	
	// reveal the dialog
	reveal(dialog);	
	
	int dummy; std::cin >> dummy; // pause
	
	return EXIT_SUCCESS;
}
