Now my widget's arrow part is not showing itself. it is in a different<br>
dimension or something like that. when i zoomout i can see the arrow part<br>
and the line but when i want to see it closer it s disappearing.<br>
Is there any body who knows what is the problem or what can be the<br>
problem...<br>
here is my code.<br>
<br>
vtkCaptionWidget *m_capWidget = vtkCaptionWidget::New();<br>
vtkCaptionActor2D *Dactor = vtkCaptionActor2D::New();<br>
Dactor->SetCaption("!!!Test Warning!!!");<br>
m_capWidget->SetCaptionActor2D(Dactor);<br>
m_capWidget->SetSelectable(321);<br>
//m_capWidget->PlaceWidget<br>
m_absWidget = m_capWidget;<br>
<br>
m_absWidget->CreateDefaultRepresentation();<br>
m_absWidget->AddObserver(vtkCommand::StartInteractionEvent,<br>
StartInteractionCallBack::New());<br>
m_absWidget->AddObserver(vtkCommand::EndInteractionEvent,<br>
EndInteractionCallBack::New());<br>
<br>
<br>
widget is turning on when mouse enters the renderwindow.<br>
<br>
so the "m_absWidget->On();" part is in the mouse enter event function.<br>
<br>
Thanx<br>
