Qt Widgets
QIrExpanderBox is a QSplitter-based container for Qt applications that contains only QIrExpander widgets. This widget is part of QIron toolkit which depends on Qt 4.6 and upper. Like for most of QIron widgets, a plugin is provided to be used in Qt Designer.
A typical use of QIrExpanderBox is:
....
QIrExpanderBox * box = new QIrExpanderBox(this);
QIrExpander * expander = box->addWidget(QIcon(...),..,new QTreeView);
expander->setExpanded(false);
box->addExpander(new QIrExpander(QIcon(...),...,new QGroupBox(...)));
....
