Debug Graphics (Draw2d/SWT) [message #230135] Thu, 01 February 2007 20:31 Go to next message

Hi everyone,
I seem to remember from a swing/java graphics tutorial once about a
setting called debug graphics or something like that where you could
enable a debugging mode where all graphics/controls were painted slowly on
the screen so you could visually watch components drawing to check for
errors/failures. I wondered if something similar exists in Draw2D so that
each figure gets drawn a second or so after each other , sort of like a
visual step through.

Does anyone know of functionality like that or how to replicate/fake it?

Thanks in advance,

Anthony

You could subclass SWTGraphics and override checkGC() to insert a delay.
Also, make sure the Canvas is not double-buffered, and the graphics source
is NativeGraphicsSource.
