How can I create QPushbutton in QPaintEvent
-
I'm newbie here.
I wonder how can I create push button in paintEvent.
I have tried create push button in MainWindow. it work! but
when I move the code to paintEvent area,it doesn't work for now.-1st- button appear and click to exit also work
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent){
QPushButton *quit = new QPushButton("Quit",this);
quit->setGeometry(50, 40, 75, 30);
// quit->setIcon(QIcon("NA03.bmp"));
connect(quit, SIGNAL(clicked()), qApp, SLOT(quit()));}
-2nd- nothing appear nor click not work!
void MainWindow::paintEvent(QPaintEvent *e)
{
Q_UNUSED(e);
QPushButton *quit = new QPushButton("Quit",this);
quit->setGeometry(50, 40, 75, 30);
//quit->setIcon(QIcon("NA03.bmp"));
connect(quit, SIGNAL(clicked()), qApp, SLOT(quit()));
}
Thank you for all comment. -
Hi and welcome to devnet,
Simple answer: Don't do that.
paintEvent, as it names suggest, is for doing some painting. Create your button in the MainWindow constructor.
I would also recommend reading the examples and demos from Qt's documentation. They'll give you a good starting point.
