[Solved] Can not set the layout of Groupbox

Hareen Laks

Hi,

I created a Qt Designer Form Class and my ui consist a groupbox.

I'm trying to programmaticaly add radioButtons to that. I'm using below code.

@Dialog::Dialog(QWidget *parent) :
QDialog(parent),
ui(new Ui::Dialog)
{
QString size;
QRadioButton *rb;
QGridLayout *grid = new QGridLayout();

foreach(size, existingSizes())
  {
       rb = new QRadioButton();
       rb->setText(size);
       grid->addWidget(rb);
  }
ui->groupBox->setLayout(grid);
ui->setupUi(this);

}@

At run time application crashes.

What is happening? I need your help.

Thanks in advance.

the problem is this:
@
ui->groupBox->setLayout(grid);
ui->setupUi(this);
@

You try to access ui->groupBox before it's getting initlized in the next step. So switch these 2 lines and the crash should be resolved.
