Recovering a pointer to QListWidget out of the QToolBox
-
Hi!
I have a QToolBox with multiple QListWidget as items/widgets inserted.
This QListWidget contains QListWidgetItem's that are checkable (Qt::ItemIsUserCheckable).I have a certain button that when clicked scans each QListWidgetItem on all these QListWidgets if they were checked or unchecked by the user.
I have a problem recovering the QListWidget out of the QToolbBox. Apparently, QToolBox doesn't have a member for QListwidget, instead it only have a member for QWidget (QToolBox::widget()).
How can I convert this QWidget to QListWidget? Though it is a QListWidget in the first place.
Thanks

you need to cast pointer from QWidget to QListWidget.
e.g.:
@
QListWidget* listWidget = qobject_cast<QListWidget*>(toolBox->widget(index));
if (listWidget != 0)
{
// success
}
else
{
// fail
}

Thanks _rmn. I will be testing your code ASAP.

e.g.:(...)[/quote]Or a bit more common (and less scope polluting):
@
if (QListWidget* listWidget = qobject_cast<QListWidget*>(toolBox->widget(index)))
{
// success, use listWidget here
}
