[Spice-devel] 答复: 答复: About mouse scroll

[ljm李嘉敏]

Hi mlureau,

Thank you for your guide, so it looks like spice renders the whole bitmap, and which region will be showed depends on the event send to gtk? I will have a test, thank you very much.

Thanks & Regards
Li JiaMin

Handling scrolling events and deciding what to redraw and how, is the job of the toolkit (gtk+/qt etc).

Spice only only does the rendering.
