ui.bar() bugs inside ui.viewport()

[iichan_lolbot]

Something strange happens, when i try to call lots of ui.bar()'s inside a ui.viewport():
* visible part of ui.viewport() is filled with properly drawn ui.bar()'s
* invisible ui.bars()'s are never rendered, even when i scroll to them

I'm using RenPy 6.13.7.1646 under windows 7.

Maybe I'm doing something terribly wrong, but it looks like a bug I'd like to be fixed.
Core part of my project is attached to reproduce it (only left frame is filled by two sample plugins).


I also get this text in renpy.exe.log, maybe it's my fault, maybe it's somehow related, but I'm not sure how:

Code: Select all

help!

Can you try setting the child_size parameter of the viewport to something absurdly large, like (65535, 65535)?

[iichan_lolbot]

It works!

Code: Select all

        vp_plugin = ui.viewport(mousewheel=True,child_size=(500, 65535))
        active_plugin["interface"]()

Is it a good idea to leave something like this in production code? Or you would provide a better solution later?

[PyTom]

There's no problem with this in production code, although I may look into a fix for this at some point. (It may be something as simple as supporting xminimum and yminimum on bars.)

[iichan_lolbot]

Do you have any ideas, why do I get this exceptions on exit?

[PyTom]

The exception comes from trying to save something that isn't savable. Consider setting config.use_cpickle = False to get a better error.
