Constructor & Destructor Documentation

◆ TreeViewLineEditComboBox()

Digikam::TreeViewLineEditComboBox::TreeViewLineEditComboBox ( QWidget *const parent = nullptr )

explicit

This class provides a TreeViewComboBox with a read-only line edit. The text in the line edit can be adjusted. The combo box will open on a click on the line edit. 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.

◆ installLineEdit()

void Digikam::TreeViewLineEditComboBox::installLineEdit ( )

protectedvirtual

Sets a line edit. Called by installView(). The default implementation is described above. An empty implementation will keep the default QComboBox line edit.

◆ installView()

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

overridevirtual

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

Reimplemented from Digikam::TreeViewComboBox.

◆ sendViewportEventToView()

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

overrideprotectedvirtualinherited

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.
