[vtkusers] vtkPropPicker and vtkRenderer onStartEvent

[chrisyeshi]

Hi,

I have a widget that inherits vtkInteractorObserver.
I got a problem that I cannot stop the chain of events by
EventCallbackCommand->SetAbortFlag(1);
Here is the sample code:

class Widget : public vtkInteractorObserver
{
...
...
public:
    virtual void SetEnabled(int enable)
    {
        if (enable)
        {
            ...
            Interactor->AddObserver(vtkCommand::LeftButtonPressEvent,
EventCallbackCommand);
            CurrentRenderer->AddObserver(vtkCommand::StartEvent,
EventCallbackCommand);
        } else
        {
            ...
        }
    };

protected:
    vtkPropPicker *m_picker;
    vtkActor *m_actor;

    virtual void onLeftButtonPress()
    {
        m_picker->PickProp(x, y, CurrentRenderer, m_picker->GetPickList());
        EventCallbackCommand->SetAbortFlag(1); <== the application seems to
ignore this line.
    };
    virtual void onStartEvent()
    {
        vtkCamera *cam = CurrentRenderer->GetActiveCamera();
        doSomething();
    }
    
};

So, why does the application keeps sending vtkCommand::LeftButtonPressEvent
to other objects after SetAbortFlag(1)?
And it only happens when I PickProp() first, so I assume the PickProp()
fires onStartEvent, and somehow it messed up in between.
Has anybody encountered this situation?

Thanks
