Having problem while using SwingLightweightGlimpseCanvas

[Caglar K]

I've been using Glimpse library for a while. I was having scroll pane problem and some additional panel refreshing issues as it is mentioned here;

https://groups.google.com/forum/#!searchin/metsci-glimpse/scroll/metsci-glimpse/Dca1GQc7q8c/4UIqd8v9eKMJ

I've followed the thread and then decided to use SwingLightweightGlimpseCanvas instead of NewtSwingGlimpseCanvas. 

Now I am able to display the content easier and lighter. But now the problem is, canvas is not being repaint after mouse action;

For example; content being displayed is not being dragged with mouse action. It only repaints after I make a very little main frame resizing with mouse.

The version of glimpse I use is 2.2.0. SwingLightweightGlimpseCanvas defined as deprecated but since it is a performance issue; I've continue with that.

The simplest explanation would be that you haven't started an animator to periodically redraw the GlimpseCanvas.

After creating your canvas, call:

        GLAnimatorControl animator = new FPSAnimator( 120 );

        animator.add( canvas.getGLDrawable( ) );

        animator.start( );

You can see a complete example of setting up a GlimpseCanvas in Example.java.

If that doesn't help, do you see any Exceptions being printed to the console when you run your application?

Also, regarding SwingLightweightGlimpseCanvas: it is deprecated, but should work fine and is still necessary if you want to do things like place a GlimpseCanvas inside a JScrollPane. It's just not as efficient performance-wise as some of the other GlimpseCanvas implementations. But if you're getting fine performance, I wouldn't worry about it.

Hi Geoffrey,

What I basically do is;

        FPSAnimator fpsAnimator = new FPSAnimator( canvas.getGLDrawable( ), 60); 

        fpsAnimator.start();

I also tried your code segment which is through GLAnimatorControl, but result is the same. It is strange that there is no exception on the console during runtime.

That is odd.

The next debugging step would be for you to create and post a simple, self-contained, single-class example which demonstrates the problem occurring in as simple a situation as possible. I'd suggest patterning it off of the examples in the Glimpse core-examples module.

To get you started, here's my example code from the previous thread you mentioned demonstrating using a SwingLightweightGlimpseCanvas with a JScrollPane: https://gist.github.com/ulmangt/11264961

A class like that which demonstrates the issue you're encountering would be ideal. That will let me reproduce the issue and look into it further.

Actually, I've been using Glimpse library for about 3-4 months. I've developed nice looking and working timeplot examples, for sure patterning them of core examples. 

I will try to create a sample for this situation when I find a suitable time period to do so.

I have also other questions, will open new threads for them.

Thanks.

I would suggest looking at the VerticallyScrollableLayoutExample. This worked for me. Using ScrollPanes never worked for me.
