Java Application vs Applet - loss of formatting
Aug 1st, 2008, 10:44am  
Hi

I'm having a problem with line formatting.

I've got Processing running fine under Eclipse by extending PApplet (Test). I have a separate class with a main method that adds the first class to a JFrame (TestDriver).
My test app just draws a thick red line;
  stroke(155, 0, 0);
  strokeWeight(9);

If I run Test by itself as an Applet all is good until I resize the window (causing a redraw?). The instant I do that I lose all formatting and I'm left with a black line of weight 1.

Running TestDriver as an application displays the line fine, but without the formatting at all.
The only time I see formatting in the application is occasionally if I run the applet, then close and run the application. The thick red line will then be displayed - until I resize or rerun it.


I haven't been able to find anything about this - no idea if I'm using the right keywords though. What am I doing wrong? Am I supposed to be able to embed this in an application?

Cheers,
FrankyG

Duh. The answer just hit me today...

I set the stroke colour and weight in setup(), like all the examples show... if I move it to draw() everything works fine.

Obviously the stroke properties are being lost on a redraw - whether this is normal or not I have no idea.

Yeah, a resize will nuke your settings for strokeWeight, textFont, etc. This is because the canvas has to be rebuilt. However, this isn't a good situation so I think we'll change it. It's also related to these two bugs:
http://dev.processing.org/bugs/show_bug.cgi?id=726
http://dev.processing.org/bugs/show_bug.cgi?id=767
Which happen even *without* the resize, which is definitely not the correct behavior. So I plan to fix all of these problems at the same time.
