[SOLVED] How to use main args

roseicollis

Hi,

I'm making a Qt Gui application so the main its like:

@
int main(int argc, char *argv[])
{
QApplication a(argc, argv); //Maybe I can do something with that?
MainWindow w;
w.show();

return a.exec&#40;&#41;;

}
@

I need to use those arguments (argc, argv[]) in the mainwindow. So my question is: How can I use them there? The only solution I can think of is to create a new class which receives them, put them in global variables and then inherite mainwindow from the new class but I don't really like it and I suposse there is an easer way to do it.
I've been searching the QApplication behaviour but nothing found

Thanks!

Hi,

You are looking for "this":http://doc.qt.io/qt-5/qcoreapplication.html#accessing-command-line-arguments part of the documentation.

roseicollis

Yeah! That's it!

@QStringList ArgsList = QApplication::arguments(); @

Next time I'll say: Hi Sgaist I think XDDD Thank you for all :D

You can do this

@
int main(int argc, char *argv[])
{
QApplication a(argc, argv); //Maybe I can do something with that?
MainWindow w(argc, argv); // And use it in your constructor of MainW
w.show();

return a.exec(&#41;;

}

Hi Francknos,

Sorry but if I do that ( I already tried it before psoting here), you can't use them in mainwindow as int a = argc; or something like that.

Anyway as the title says, it has been already solved so thanks :)

Ok no problem.
But why you want modify the argc, argv in your app ?

roseicollis

I didnt want to modify them, just to use them :)
