QListWidget::setItemWidget???
Message 1 in thread
I can't seem to get this function to work at all, what is it supposed to
do? What I want to be able to do is to have a QListWidget that I extend
that contains items that are user interactable (such as a QPushButton
and a QComboBox). It looks like setItemWidget should do exactly what I
want it to do, but it doesn't - it always places the actual
QTableWidgetItem on top of the widget I pass setItemWidget. What am I
doing wrong? Here's what I'm doing:
QListWidgetItem *listItem = new QListWidgetItem(tr("Filter Item"));
//The following is valid because QListWidget is being extended
addItem(filterItem);
QComboBox *com = new QComboBox();
com->addItem("1");
com->addItem("2");
com->addItem("3");
QPushButton *but = new QPushButton();
but->setText("+");
QBoxLayout *layout = new QBoxLayout(QBoxLayout::LeftToRight);
layout->addWidget(but);
layout->addWidget(com);
QWidget *widget = new QWidget();
widget->setLayout(layout);
setItemWidget(listItem, widget);
widget->show();
It works fine if I pick one widget (QComboBox or QPushButton), but not
when I combine widgets in this way. Any help is greatly appreciated.
Thanks,

Did you debug into the ListView to find out what is happening? Have you
tried using a custom delegate with the QListView and a QStandardItemModel?
