QPushButton appears differently

[gianhut]

For some reasons, QPushButton shows up differently even though the code is mostly the same. Has anyone experienced the same issue and possibly have fixed it??

Here are the details:

QApplication app(argc, argv);
 
	QPushButton btnQuit("Exit");
	btnQuit.resize(75, 30);
	btnQuit.setFont(QFont("Times", 18, QFont::Bold));
 
	QObject::connect(&btnQuit, SIGNAL(clicked()), &app, SLOT(quit()));
 
	btnQuit.show();
 
	return app.exec();

QApplication app(argc, argv);
	
	QPushButton btnQuit("Exit");
	btnQuit.resize(75, 30);
	btnQuit.setFont(QFont("Times", 18, QFont::Bold));
	
	QObject::connect(&btnQuit, SIGNAL(clicked()), &app, SLOT(quit()));
	
	btnQuit.show();
	
	return app.exec();

To copy to clipboard, switch view to plain text mode 

results in:

QApplication appl(argc, argv);
 
	QWidget wnd;
	wnd.resize(200, 120);
 
	QPushButton btnQuit("Exit", &wnd);
	btnQuit.resize(75, 30);
	btnQuit.setFont(QFont("Times", 18, QFont::Bold));
	btnQuit.setGeometry(10, 40, 180, 40);
	QObject::connect(&btnQuit, SIGNAL(clicked()), &appl, SLOT(quit()));
 
	wnd.show();
	return appl.exec();

QApplication appl(argc, argv);
	
	QWidget wnd;
	wnd.resize(200, 120);
	
	QPushButton btnQuit("Exit", &wnd);
	btnQuit.resize(75, 30);
	btnQuit.setFont(QFont("Times", 18, QFont::Bold));
	btnQuit.setGeometry(10, 40, 180, 40);
	QObject::connect(&btnQuit, SIGNAL(clicked()), &appl, SLOT(quit()));
	
	wnd.show();
	return appl.exec();

Sorry for posting twice, but I figured out that the setGeometry method made the difference in the appearance. However, since I'm a newbie to Qt, I don't know how to work resolve this

[ComaWhite]

setGeometry() is the same as calling

resize();
move();

[gianhut]

setGeometry() is the same as calling

resize();
move();

I did try replacing setGeometry with resize and move, and the same thing still happened

In the second example there are two widgets (wnd and btnQuit) whereas in the first there is only one (btnQuit). Otherwise speaking in one example widget is parentless and in the other it has a parent. Does that ring a bell?
