<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have a Java application that use vtkPanel. Precisely, I made a class that extends vtkRenderWindowPanel. When an object of the class is no more used, I would like to dispose the object. But I couldn’t dispose it no matter how. Java VisualVM
indicates the object is JNI global reference. So how can I dispose it? I used the Delete method and called vtkObject.JAVA_OBJECT_MANAGER.gc(false), but it didn’t work (it works for other VTK objects). The attached file is a simple test code that demonstrates
vtkRenderWindowPanel is never disposed.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have seen similar post in the past, but never be answered in the way I hope. So I decided to post. I would appreciate any advice.</p>
<p class="MsoNormal">Thank you,</p>
<p class="MsoNormal"> </p>
