Problem drawing a QPixmap on screen with a QPainter
-
So my code basically looks like this (where the code is placed in the constructor of a class that inherits from QWidget)
@
QPainter p(this);
QPixmap temp;
QString fileName = "folder/art.png";
if (temp.load(fileName) == false)
{
QMessageBox mb(this);
QString qs("Failed to load " + fileName);
mb.setText(qs);
mb.exec();
} else {
QMessageBox mb(this);
QString qs("Loaded image " + fileName);
mb.setText(qs);
mb.exec();
}
p.drawPixmap(200, 200, temp);
@The image loaded fine but won't draw on the screen. Have also tried using the repaint() method after the call to p.drawPixmap(...);
Any help would be much appreciated,
Thanks

To draw on a widget with your own code, you must reimplement "QWidget::paintEvent() ":/doc/qt-4.8/qwidget.html#paintEvent. You cannot draw in the constructor of a widget.

Thanks for the quick response. This is indeed my problem here.
