Summary

0007107: [VTK JAVA] vtkCanvas with JSplitterPane crash on Windows

Description

- Add 2 vtkCanvas to a JSplitterPane
- vtkCanvas are properly displayed
- Move the split bar
- vtkCanvas are no longer displayed

This only happen on Windows. It does not happen if JSplitterPane.setContinuousLayout(true) is called before. A workaround is to create the vtkCanvas as this:

vtkCanvas toReturn = new vtkCanvas()
{
@Override
public void removeNotify(){}
}

Note that I don't understand why this fix the bug and that it's probably not a clean solution.

Additional Information

/** A program to reproduce the bug */

import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JSplitPane;
import javax.swing.WindowConstants;
import vtk.vtkActor;
import vtk.vtkCanvas;

/**

public class BugJSplitter
{
    private static vtkCanvas createCanvas()
    {
        vtkCanvas toReturn = new vtkCanvas();

        // see http://www.vtk.org/Bug/view.php?id=6287 [^]
        toReturn.setMinimumSize(new Dimension(0, 0));
        toReturn.setPreferredSize(new Dimension(0, 0));

        toReturn.GetRenderer().AddActor(new vtkActor());
        return toReturn;
    }

    public static void main(final String[] args)
    {
        JFrame frame = new JFrame();
        frame.setSize(800, 600);
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        JSplitPane pane = new JSplitPane();
        frame.getContentPane().add(pane);
        pane.add(createCanvas(), JSplitPane.BOTTOM);
        pane.add(createCanvas(), JSplitPane.TOP);
        frame.setVisible(true);
    }
}
