Unsolved How to prevent open form?
-
Hi,
I use below code to open new UI form.mUrunAgacAl = new UrunAgacAl(this); mUrunAgacAl->showMaximized();
I want to check authority of the user if he/she can open and use form?! In this case I check authorization in the setup section of the form before than below code;
ui->setupUi(this);
My code is:
if(!auth){ QMessageBox::warning(this,"No permission!", "You can not use this form Exiting..."); this->close(); return; }
But above code is not working. Form is still opening?!
I tyed also ;this->destroy(true,true);
But still openning but emty page!
I just want to prevent opening form and delete from memort ofcourse?! How can I do it?

@Mucip Why not
if(auth){ mUrunAgacAl = new UrunAgacAl(this); mUrunAgacAl->showMaximized(); } else { QMessageBox::warning(this,"No permission!", "You can not use this form Exiting..."); }

Hi
Dont do it in the constructor.
Its too late there. Object being constructed at that moment.
so be much better if you did BEFORE creating the UrunAgacAl. -
Dear @jsulm ,
In this case I need to control for every form. In the beginning I don't know the ID of the form. But If I can make the form self control then it will be much esaier for me unfortunatelly!... :(Regards,

Dear @mrjj ,
It's very difficult for me! It's better to make this control to form own!..Regards,

@Mucip In my opinion it is a bad idea to let each form to decide whether it should be shown or not. This decision should be taken (ideally) in one place.

Hi
I agree with its not the best way but lets say we must do it.I was wondering cant you do like
mUrunAgacAl = new UrunAgacAl(this);
if (! UrunAgacAl->auth ) {
mUrunAgacAl->close();
mUrunAgacAl->deletelater();
} else
mUrunAgacAl->showMaximized(); -
Hi,
