Canvas

Troubleshooting General Help
1

Hi,

I created a canvas like this:



Canvas comp = DisplaySystem.getDisplaySystem("lwjgl").createCanvas(width,
               height);



If I set the background color of the canvas

comp.setBackground(new java.awt.Color(255,255,255));



directly after the canvas creation, I get a NullPointerException. So, I have to give comp to the SimpleCanvasImpl extended class and call comp.setBackground from the simpleSetup() method. Would be nice, if the canvas could be initialized with a specified background color within the parent class.

Best,
Andreas

I belive you want to change the background color on the renderer, not the canvas.


DisplaySystem.getDisplaySystem().getRenderer().setBackgroundColor( ColorRGBA.white );

Thanks. That works int the simpleSetup(), too.
