QStatusBar and QProgressBar

[croscato]

Hi all.

I'm wish to add a QProgressBar to a QStatusBar in QMainWindow. But it must not be visible all the time.

I'm using a code similar to this and can't get it to work

Form::Form(QWidget* parent): QMainWindow(parent)
{
    progress = new QProgressBar(this);
    progress->setVisible(false);
 
    statusbar->addPermanentWidget(progress);
}
 
Form::showProgress(bool visible)
{
    progress->setVisible(visible);
}

Form::Form(QWidget* parent): QMainWindow(parent)
{
    progress = new QProgressBar(this);
    progress->setVisible(false);

    statusbar->addPermanentWidget(progress);
}

Form::showProgress(bool visible)
{
    progress->setVisible(visible);
}

To copy to clipboard, switch view to plain text mode 

Any ideas???

Thanks in advance!
