Hmmm.... that is weird as I can get mouse moves. Please see code below.<br><br>vtkEventQtSlotConnect * connections = vtkEventQtSlotConnect::New();<br><br>.. connections->Connect(interactorROI,<br> vtkCommand::MouseMoveEvent,<br>
this,<br> SLOT(handleMouseMove()));<br><br>..<br><br>// The slot<br>void myScene::handleMouseMove()<br>{<br> // get event position<br> int event_pos[2];<br> interactorROI->GetEventPosition(event_pos);<br>
qDebug("Move: x=%d : y=%d\n", event_pos[0], event_pos[1]);<br>}<br><br><br><br>Unfortunately the mouse release of any button is still dysfunctional, which is a travesty as this<br>is otherwise a very useful class. I wish someone would fix this.<br>

Dear Imran,<br>
<br>
My name is Kourosh and I am a VTK user. I saw the following posting from you regarding vtkEventQtSlotConnect not being able to capture mouse release. I actually faced the same problem. I even cannot get the position of mouse when I move the mouse without clicking. Did you find any solution for this problem?<br>
<br>
I highly appreciate your kind help.<br>
<br>
Best regards,<br>

P.S.<br>
Your posting:<br>

I have a windows application where I instrumented connecting the mouse events in QVTkWidget to slots and noticed that NONE of the mouse RELEASE events<br>
can be captured into a slot using vtkEventQtSlotConnect.<br>
connections = vtkEventQtSlotConnect::New();<br>
connections->Connect(interactorROI,<br>
vtkCommand::EnterEvent,<br>
this,<br>
SLOT(handleMouseEnter()));<br>
connections->Connect(interactorROI,<br>
vtkCommand::LeaveEvent,<br>
this,<br>
SLOT(handleMouseLeave()));<br>
connections->Connect(interactorROI,<br>
vtkCommand::LeftButtonPressEvent,<br>
this,<br>
SLOT(handleMouseLeftButtonPress()));<br>
connections->Connect(interactorROI,<br>
vtkCommand::LeftButtonReleaseEvent,<br>
this,<br>
SLOT(handleMouseLeftButtonRelease()));<br>
connections->Connect(interactorROI,<br>
vtkCommand::MouseWheelForwardEvent,<br>
this,<br>
SLOT(handleMouseWheelForward()));<br>
connections->Connect(interactorROI,<br>
vtkCommand::MouseWheelBackwardEvent,<br>
this,<br>
SLOT(handleMouseWheelBackward()));<br>
connections->Connect(interactorROI,<br>
vtkCommand::RightButtonPressEvent,<br>
this,<br>
SLOT(handleMouseRightButtonPress()));<br>
connections->Connect(interactorROI,<br>
vtkCommand::RightButtonReleaseEvent,<br>
this,<br>
SLOT(handleMouseRightButtonRelease()));<br>
All other mouse events work.<br>
I noticed that a couple of other folks<br>
Constantine Zakkaroff adn Tamaron : vtkEventQtSlotConnect skips vtkCommand::LeftButtonReleaseEvent?<br>
Have also experienced this. This is a very basic functionality for me to use the QVTKWidget. I hope someone can suggest<br>
a solution or a workaround.<br>
