Constructor & Destructor Documentation

◆ ListViewComboBox()

Digikam::ListViewComboBox::ListViewComboBox ( QWidget *  parent = nullptr)
explicit

This is the standard view of a QComboBox, but in conjunction with StayPoppedUpComboBox some extra steps are needed. You need three steps: Construct the object, call setModel() with an appropriate QAbstractItemModel, then call installView().

Member Function Documentation

◆ installView()

void Digikam::ListViewComboBox::installView ( QAbstractItemView *  view = nullptr)
virtual

Call this after installing an appropriate model.

Reimplemented in Digikam::ChoiceSearchComboBox.

◆ sendViewportEventToView()

void Digikam::ListViewComboBox::sendViewportEventToView ( QEvent *  e)
overrideprotectedvirtual

This method is protected for a usual QAbstractItemView. You can override, pass a view, and call parent implementation. The existing view will be used. You must then also reimplement sendViewportEventToView.

Implements Digikam::StayPoppedUpComboBox.

◆ view()

QListView * Digikam::ListViewComboBox::view ( ) const

Valid after installView() has been called.
