Hi,
I don't know about IntLeaveWidget, but there is an eraser tool in the
segmentation plugin that uses the
PressMoveReleaseWithCTRLInversionAllMouseMoves interaction statemachine. This
interaction is located in the Resources/Interactions folder of the Segmentation
module.
Best,
Stefan

Betreff: [mitk-users] DataInteractor: IntLeaveWidget
Hi everyone,
I am trying to implement a DataInteractor for an Eraser tool.
For this I want to visualize the erasers Region in the RenderWindow.
I figured that I can do this using a mitk::Annotation2D to render a
Shape(transparent circle) that I reposition on every MouseMove event.
However, there is no MouseMove event once the cursor leaves the RenderWindow.
The shape than just stays at the last position within the window.
When I looked for a solution, I stumbled over DataInteractor::IntLeaveWidget
which, according to the comment is an internal event.
However, connecting to this event, directly (CONNECT_FUNCTION) or in the
StateMachine configuration (transition with event_class="InternalEvent"
event_variant="LeaveWidget") has no effect.
Is this internal event still in use and if so, how can I connect to it? Are
there other approaches to this problem?
Kind regards,
Bertram
