Hi all,<br>
<br>
I'm embeddeding a vtkPanel into a java swing based application.<br>
The parent widget is a JTabbedPane.<br>
My code captures mouseMoved to pick the actor hovered by the mouse pointer.<br>
I've looked a bit in the pick code and vtk asks actor if they need to render.<br>
The problem is I get mouseMoved even when mouse is not moved<br>
(I've tried an action with a menu using keyboard).<br>
If the render is not done the pick will fail while trying to render (ChoosePixelFormat)<br>
<br>
I've enabled vtk message confirmation and took a stacktrace with process explorer<br>
<br>
vtkRendering.dll!<u></u>vtkWin32OpenGLRenderWindow::<u></u>SetupPixelFormat+0x44d<br>
vtkRendering.dll!<u></u>vtkWin32OpenGLRenderWindow::<u></u>CreateAWindow+0x38a<br>
vtkRendering.dll!<u></u>vtkWin32OpenGLRenderWindow::<u></u>WindowInitialize+0x71<br>
vtkRendering.dll!<u></u>vtkRenderWindow::DoAARender+<u></u>0x389<br>
vtkRendering.dll!<u></u>vtkRenderWindow::Render+0x326<br>
vtkRenderingJava.dll!Java_vtk_<u></u>vtkLineIntegralConvolution2D_<u></u>GetMagnificationMinValue_133+<u></u>0x1f <br>
<br>
<br>
I've got two different errors but both are related to actor picking, I may add some code to avoid picking<br>
if the vtkPanel is not ready to pick, but looks like there is no way to known if I can pick, at least from java<br>
<br>
Regards,<br>
<br>
Dario<br>

Problem solved by testing isWindowSet() before picking.<div class="HOEnZb"><div class="h5"><br>
