Refreshing a Window in Java

I'm using the JFreeChart library to draw charts in Java, blahblah...

I need the chart to draw on button click, how do I refresh the window without having to use setVisible(false) then setVisible(true)?

repaint() doesn't do shit.

Figured it out... invalidate() then validate() refreshes the window without any popping, blinking or niggering about.

ok I lied, it's still gay...

how the hell do I get it to remove the chart element from the panel, re-add it and then re-draw it?

so I remove the chart from the panel, but then what? I've tried re-validating the panel, repainting the window, re-validating the window, etc. but the original chart won't gtfo

GC is shit.

I agree 100%, which is why I fucking hate Java. That said, I need to use it for this asshole class, and I can't figure this shit out.

You have to be kidding me, this is such shit. This doesn't even work:


            //Add new chart to panel & update window
            window.invalidate();
            window.remove(panel);     //Remove panel from window
            panel.remove(chartPanel); //Remove chart from panel
            panel.repaint();
            panel.add(chartPanel);    //Add new chart to panel
            window.add(panel);        //Add panel back to window
            window.validate();

figured it out, peace fags

If GC is why you hate Java, you haven't been using Java long enough. There are much, much better reasons to hate it.

fuck off and die you cock sucking faggots

Doesn't stop JVM's GC from being slow as fuck
That, and the horrible syntax, and the horrible API, and how it shoves OOP's in its shittiest down your throat.

Actually syntax is one of the cleanest. You might be bitching about semantics, which is what Java terribly fails at.
