Hi all,
I previously sent a tooltip implementation using a JWindow to another
list that will solves your problem also. The code is in the forwarded
email far below. This is how you can use it in a Canvas3D:
public class ViewDlg extends JDialog
{
private View3D view3D;
private SiteTree siteTree;
private PopupTip popup = new PopupTip(); //this is the class
public Site3DView()
{
JPanel panel = new JPanel(new BorderLayout());
view3D = new View3D();
this.getContentPane().add(panel);
Dimension dim = this.getToolkit().getScreenSize();
setBounds((int) (dim.width*.5-350), (int) (dim.height*.5-350),700,
700);
siteTree = new SiteTree();
JSplitPane tSplitPane = new
JSplitPane(JSplitPane.HORIZONTAL_SPLIT, siteTree, new JScrollPane(view3D));
tSplitPane.setLastDividerLocation(200);
panel.add(tSplitPane,BorderLayout.CENTER);
setVisible(true);
}
public class View3D extends JPanel
{
Canvas3D canvas3D = new
Canvas3D(SimpleUniverse.getPreferredConfiguration());
SimpleUniverse simpleU = new SimpleUniverse(canvas3D);
TransformGroup rootTransG = new TransformGroup();
BranchGroup rootBranchG = new BranchGroup();
public View3D()
{
rootBranchG.setCapability(BranchGroup.ALLOW_DETACH);
simpleU.getViewingPlatform().setNominalViewingTransform();
this.setLayout( new BorderLayout() );
this.setOpaque( false );
this.add("Center", canvas3D);
canvas3D.addMouseMotionListener(new MouseMotionAdapter()
{
public void mouseMoved(MouseEvent e)
{
Point pt = e.getPoint();
popup.showAt(pt.x + ","+pt.y,view3D,pt.x,pt.y,100,15);
}
});
}
}
}

this.setBounds(x+15,y+15,width+7, height+7);
this.setVisible(true);
this.toFront();
}
