Constructor & Destructor Documentation

◆ TreeViewComboBox()

Digikam::TreeViewComboBox::TreeViewComboBox ( QWidget * parent = nullptr )

explicit

This class provides a QComboBox with a QTreeView instead of the usual QListView. You need three steps: Construct the object, call setModel() with an appropriate QAbstractItemModel, then call installView() to replace the standard combo box view with a QTreeView.

◆ installView()

void Digikam::TreeViewComboBox::installView ( QAbstractItemView * view = nullptr )

virtual

Replace the standard combo box list view with a QTreeView. Call this after installing an appropriate model.

Reimplemented in Digikam::TreeViewLineEditComboBox, Digikam::AbstractAlbumTreeViewSelectComboBox, and Digikam::AlbumSelectComboBox.

◆ sendViewportEventToView()

void Digikam::TreeViewComboBox::sendViewportEventToView ( QEvent * e )

overrideprotectedvirtual

Implement in subclass: Send the given event to the viewportEvent() method of m_view. 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.
