signal and slots between two classes

[mrjj]

also how does you main.cpp look like ?

You show the Dialog instead of mainwindow?

[marlenet15]

@mrjj

#include "dialog.h"
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Dialog *w = new Dialog();
    w->showNormal();

    return a.exec();
}``` 

and yes I used Dialog instead of mainwindow

Hi I think the dialog in dialog mess up something.
Didnt work for me if I new the sign dialog in Start dialog constructor.
But it does work if I hooked it up outside.
Have a look at this example

Its the same idea but created slightly different.

[marlenet15]

@mrjj I followed your example but it is still not working.

[mrjj]

@marlenet15
??
so the getnext example which runs here do no work when you compile it?

[marlenet15]

@mrjj ok it works. I redid my code using only QWidgets and it works. I think I know the problem and I forgot to mention it. I made QDialog a stacked widget and promoted the file signin.

Ok, as far as I know you cannot connect signal to signal

You can. See the documentation:

You can connect as many signals as you want to a single slot, and a signal can be connected to as many slots as you need. It is even possible to connect a signal directly to another signal. (This will emit the second signal immediately whenever the first is emitted.)

[mrjj]

@JKSH
Aha, that is news for me. so that is like a chain signal or almost like an alias.

@marlenet15
Super. not sure what the real reason was but as long as it works :)

[marlenet15]

@mrjj Before creating the stackedwidget it worked. After adding it, it doesn't work anymore.

[mrjj]

@marlenet15
Ok. do you promote a qDialog to a stackwidget ?
Not sure I fully understand.
At least I have never tried that.

[marlenet15]

@mrjj on the .ui file of the class dialog, I created a stackedwidget and promoted the file signin.h

[mrjj]

@marlenet15
so the signin dialog was sort of inline to Dialog ?

[marlenet15]

@mrjj can you exaplain what you mean by that? Sorry

[mrjj]

@marlenet15
Hi np.
Im not 100% sure what you did.
If you promote a widget to a dialog.
the dialog will be sort of inside the parent/widget that contains the
promoted widget.
So I wondered if you promoted a stacked widget to the signin dialog ?

[marlenet15]

@mrjj I created a stackedwidget in dialog.ui, in there I promoted signin.h into the stackedwidget.

[mrjj]

ahh that way. Hmm should be the same as using a plain qwidget but seems it was not.

Can I ask what kind of design u are after ?
like sort of custom wizard style thing ?

[marlenet15]

@mrjj yes I am. I am doing something simple now in order to understand how it works so that later I can use it so that when i click the button, it goes to the next page.

[mrjj]

@marlenet15
Ok. but you want it to be standalone Dialogs or pages in a stacked widget ?
or you want to use UI files that you promote into the stacked widget?

[marlenet15]

@mrjj pages in a stackedwidget. I figured it out how to make it work through code but I am having a difficult time make it work only through Qt Designer/.ui file

[mrjj]

@marlenet15
Ok. well I think such wizard do need code if not just a Dialog with a stacked widget and the the Next button outside of the stacked.
