[Gimp-developer] Filtering image on parameter change

[Grzegorz Karch <grzegorz karch gmail com>]

Hi,

I'm working on a plugin for which I would like to have the image refreshed every time the user changes some parameter in the dialog. That is, instead of viewing changes in the preview window, I wouId like to see them in the working space, just like in the case of Brightness-Contrast filter (or any other in "Colors" menu). Could you give me any hints on which functions I need to use? Or is there any relevant example? I tried to look into the source code (gimpbrightnesscontrasttool.c, for instance) but I couldn't make head nor tail of it...

Regards,
Grzegorz
