Qt gfx plugin

[nvharisha]

Hi,

I have QtWebkit working on ARM platform. I have two plugins in -QT- Qt, one for Graphics ( QScreenDriverPlugin) another for Keyboard.
For graphics driver, I took the sample driver from one of the example and have written it.

My graphics plugin implements getting pointer to an OSD Surface, blitting to on-screen memory etc. I find that when ever qtwebkit based browser tries to load webpage , internally it creates a QImage, and then puts all the data into it and then finally the object is passed on to plugin for copying into the surface.

In the above scenario, I would like to use the back-screen memory (Another Surface) instead of normal "Malloc-ed" QImage memory. This helps in speeding up things. The back-screen memory can be obtained from plugin (Which currently qtwebkit is not calling).
My knowledge in -QT- Qt is very limited. So any one have any ideas on how it can be achieved, please let me know.

Thanks
