Hi Bertram,
I don't know If I understood you correctly but you might take a look at
QmitkRenderWindow::leaveEvent.
Here a mouse move that leaves a render window is recognized and an internal
event 'LeaveRenderWindow' is created and handled.
You might check e.g. the 'BoundingShapeInteraction.xml' to see the use of this
leave render window event.
Best,
Amir

Hi Stefan,
I thought about that too but the problem is that there are no more MouseMove
events once the cursor leaves the RenderWindow so checking the coordinates in a
condition won't help.
Kind regards,
Bertram

Hi Bertram, I didn't dig deeper into this to check if there isn't something
like a working MouseLeave event but you always can, for example, add a
condition to your statemachine [1] and check yourself in the callback function
if the new mouse coordinates are still inside the renderwindow and if they are
not traverse to another custom state like MouseLeft or something like that and
react appropriately.
Best,
Stefan

Hi Stefan,
Thanks for the suggestion, however when trying the Segmentation plugins eraser
tool I noticed that it has the exact same problem that I'm trying to solve:
When leaving the RenderWindow the eraser shape stays at the position of the
last MouseMove event until the mouse enters any of the RenderWindows again. Is
there no way to detect the mouse leaving the window?
Kind regards,
Bertram

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.

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
