Add widget from custom class to MainWindow

[Tamfub]

@mrjj Actually it is ok with the Char* in place of the QLabel, so I would put that apart for now.
I tried to:

• declare IPCtrl *ip_field (a pointer, as you suggested) in mainwindow.h

• write ui->formLayout->addRow("IP Address", ip_field->window()); ip_field->show(); (then with the arrows in place of the dots) in mainwindow.cpp

the application starts but the UI won't just appear...

Ok the window() part makes no sense to me.

Looking at the code, it just seems like a normal custom widget.
Did you change the code shown on SO or used it as is ?

[Tamfub]

@mrjj I used it as is, no changes.

@Tamfub
Ok i did fast test.
It just compiles so not sure why you get so much grief from it :)

ui->formLayout->addRow("test", field);

test project.

@mrjj Ok, it worked also for me now, the error in addRow disappeares when ip_field is declared as a pointer. I did not try this XD

Thank you very much!

@Tamfub
Np :)
yes it must be pointer OR you must use the & to take address but
due to how deletion works, it's best to use pointer :)

@mrjj Got it! Do you know why the right border of the textEdit is not visible?

[mrjj]

@Tamfub
It seems the last Edit touches the QFrames border.
but even if i make it HUGE, it still happens so its
its seems to be due to
pLayout->setContentsMargins( 0, 0, 0, 0 );
so you can fix it with
pLayout->setContentsMargins( 0, 0, 1, 0 );
Seems not to give ill side effects.

ps. in
IPCtrl::IPCtrl(QWidget *parent) : QFrame(parent)
