Clicking through GUI

[brokk]

I searched the forums, but I couldn't find the thread.

I have a GUI and I forget how to make it so you can click through it.
The image is a sun effect I'm testing but you can't click on my quick slot buttons.

PHP Code:

  new GuiBitmapCtrl("Sun") {
  x = 0;
  y = 0;
  width = screenwidth;
  height = screenheight;
  bitmap = "sun_test.png";
  layer = 0;
  }
