clear area in which controlP5 controls are drawn
Apr 15th, 2010, 12:18pm  
I have set aside a rectangle, like a toolbar, at the top of the drawing area in which I place some controlP5 sliders and labels. The actual drawing is done below this toolbar rectangle. But some times the drawing spills over into the toolbar area. How do I clear this area ?The usual method of filling the rectangle with a color does not work. Setting controlp5 autodraw as false also did not help.

Sad, ok, to rephrase my question: How do I clear/erase/draw-on the background of the area in which controlp5 controls are drawn ?

Setting autodraw to false, filling the area with some color and manually drawing the controls (with controlP5.draw) did not help.

Add these two lines of code between drawing your scene and drawing the toolbar:

hint(DISABLE_DEPTH_TEST);
hint(ENABLE_DEPTH_TEST);

Thanks for the response. But I am not using 3D. In any case, the statements you mentioned did not help. May be I misunderstood how to use them.

I am sorry. It was all due to a mistake on my part. I had used a hexadecimal color  for fill() without knowing that you have to specify an alpha part when doing so.
