I have a program that is using a QSceneGraph and a series of custom
QGraphicsWidgets.
I now want to use a QProgressDialog as a top-level window (_not_ embedded in
the QSceneGraph) from within the QGraphicsWidget.
My code is calling the hide/show on the QProgressDialog instance, but I don't
see anything at run-time.
I first just used the QProgressDialog on its own; and the program worked at
run-time but without the dialog showing; stopping the program would, however,
cause it to crash.
So I looked at QGraphicsProxyWidget and wrapped it with that - which prevents
the crashes but doesn't otherwise solve the issue.
My goal is to have the QProgressDialog widget pop-up while the program does a
background task, then go away when its done.
I don't want it as part of the QGraphScene - more as a modal window.
Some example code of what I am basically doing:
class myGraphicsWidget : public QGraphicsWidget {
...
QProgressDialog progressDlg;
QGraphicsProxyWidget proxyProgressDlg;
...
};
...
myGraphcisWidget::myGraphicsWidget(QGraphicsItem* _parent) :
QGraphicsWidget(_parent), progressDlg(NULL) {
proxyProgressDlg.setWidget(&progressDlg);
}
...
void myGraphicsWidget::someSignal1(int _someValue) {
progressDlg.show();
progressDlg.setMaximum(_someValue);
}
...
void myGraphicsWidget::someSignal2(int _progress) {
progressDlg.setValue(_progress);
}
...
void myGraphicsWidget::someSignal3() {
progressDlg.hide();
}
...
I'm sure that I must be doing something wrong, but I'm not sure what...I
haven't tried this before with QGraphics functionality.
