Application crashes at launch-time

[Salazaar]

I think public Ui:ialog is needed to access gui elements

[high_flyer]

as I said, READ about it more.
You have a private ui elements which you use in your Dialog class.
If you use that approach you don't need to sublcass, one of the nice things about Qt4 ui way.

[Salazaar]

Right. But there is an error in line

app.setMainWindow(window);

app.setMainWindow(window);

To copy to clipboard, switch view to plain text mode 

class QApplication has no member named setMainWindow

[high_flyer]

that is correct.
What do you do then?

[Salazaar]

I don't know

[high_flyer]

Read the docs maybe??

[Salazaar]

Yes, I'm using assistant. I would check it in docs, but I just written that I don't know what's the problem about

[Salazaar]

I made this changes you post, but when i launch application, only dialog window appear. I mean, no gui elements are displayed, only empty window. is that a 'typo'?

[high_flyer]

I mean, no gui elements are displayed, only empty window. is that a 'typo'?

Yes, but this time its yours:

int main(int argc, char *argv[])
 
             {
     QApplication app(argc, argv);
     QApplication::setStyle ( new QPlastiqueStyle() );
     //QDialog *window = new QDialog;
     Dialog *window = new Dialog;
     window->show();
     return app.exec();
 }

int main(int argc, char *argv[])

             {
     QApplication app(argc, argv);
     QApplication::setStyle ( new QPlastiqueStyle() );
     //QDialog *window = new QDialog;
     Dialog *window = new Dialog;
     window->show();
     return app.exec();
 }

To copy to clipboard, switch view to plain text mode

Salazaar, please read and at least try to understand the code you write. I think you should be able to distinguish between "QDialog" and "Dialog".

[Salazaar]

It should be new Dialog. Right?

[wysota]

Salazaar, are you using Qt Assistant? It has nice indexing and searching functions...

[high_flyer]

Oh allrgiht...
Salazar - I had a typo when in the code, and thought it might be a good lesson for you...
It should be QApplication::setMainWidget ()

[wysota]

Actually you shouldn't need that line at all.

[high_flyer]

True.
But it doesn't hurt.
