Hi,
Right... some time has passed since I began working on the runtime configuration bits. But I've picked up the work and created some new features. Ofcourse, everything is still beta and needs quite some extra work to be really useful. But still, I think this is the way to go.
I've included a few 'patches' for CVS HEAD. There are three new files and two patches:
- popupbox.py.patch. I needed a functional InputBox, so I rewrote that part. It's far from complete, but it suited my current needs for both strings and integers
- configuration.py. The main menu plugin. Should go into src/plugins
- runtimexml.py. The heart of the runtime configuration. Should go into src/config
- runtime_config.tpl.fxd. This is the template for all the configuration variables. Put it in share/fxd
- __init__.py.patch. This is a patch for the file src/config/__init__.py. It's needed to initiate the runtime configuration at startup. Just a quick hack to get things working.
As always, I've created these patches and files with my limited knowlegde of Freevo. So I bet things can be done easier and better, but I'm not familiar with all of the code :)
The configuration menu item is not very useful yet. But you can edit two values: 'Video' > 'MPlayer' -> 'Audio device' and 'TV' > 'Record' -> 'Padding'. The first one is a string, the second one an integer.
That's all for now :)
Kinds regards, Eric
