Hello,
I am currently working on a data node picking functionality for my
plugin. My plugin uses the OnSelectionChanged method provided by
Qmitkabstractview. When I click on a node inside the data manager view
this method is called, as expected. But when I try to pick a node inside
the renderer it is not called. My picker sets the picked node selected
in two ways:
1. Setting the selection of the data manager view
mitk::DataNodeSelection::Pointer selection(new
mitk::DataNodeSelection(pickedNode));
this->SetDataManagerSelection(selection);
2. Setting the selected attribute of the node
pickedNode->SetSelected(true);
But still, there is no call of OnSelectionChanged. Then I checked how
this method is called:
q->OnSelectionChanged(sourcepart,
this->DataNodeSelectionToQList(_DataNodeSelection));
inside QmitkAbstractView::BlueBerrySelectionChanged(...)
The same here, it is also not called. Diving deeper...
BlueBerrySelectionChanged is the callback function for the selection
listener:
// REGISTER FOR WORKBENCH SELECTION EVENTS
d->m_BlueBerrySelectionListener = berry::ISelectionListener::Pointer(
new
berry::NullSelectionChangedAdapter<QmitkAbstractViewPrivate>(d.data(),
&QmitkAbstractViewPrivate::BlueBerrySelectionChanged));
this->GetSite()->GetWorkbenchWindow()->GetSelectionService()->AddPostSelectionListener(d->m_BlueBerrySelectionListener);
It seems that no selection event is entering the selection service. So I
thought that I could add one by using FireNodesSelected(...). But that
did not work neither. Now I am wondering about how to proceed. Is it the
right way to try to implement my own selection provider in order to call
BlueBerrySelectionChanged()? Do I overlook something?
Thank you very much for your help.
Best regards,
Martin
