PyGtk CellRendererProgress start/end positions

Is there any way to fill a gtk.CellRendererProgress indicating the start and end positions? Not just the end.

As an example of what I 开发者_运维百科would need to do is, instead of this:

|##############################----------| (from 0% to 80%)

I need to do this:

|--------######################----------| (from 25% to 80%)

It's like a pulsing ProgressBar but without moving and I need to specify at wich percentage the bar starts and ends.

Thanks

No, you can't do that. But you can write a custom cell renderer that does that, based on the code for CellRendererProgress.
