How to disable a QLineEdit?

[ewwen]

Hi tinysoft!

Thank you very much. With your file and some work I found the problems:
1) I was missing:

in1->setDisabled(1);....

in1->setDisabled(1);....

To copy to clipboard, switch view to plain text mode 

2)

QWidget *widget = new QWidget;
         setCentralWidget(widget);

QWidget *widget = new QWidget;
         setCentralWidget(widget);

To copy to clipboard, switch view to plain text mode 

because of QMainWindow. QWidget, for example, is a member of it.
and
3) I removed the GroupBox and just used:

QGridLayout *formLayout = new QGridLayout;
  ...
 widget->setLayout(formLayout);

QGridLayout *formLayout = new QGridLayout;
  ...
 widget->setLayout(formLayout);

To copy to clipboard, switch view to plain text mode 

Now everything works fine :-)!

Thanks for your hints and have a nice day!
