    Joxy Look and Feel

    Joxy Look and Feel

    Java Swing Look and Feel for integration with the KDE Oxygen theme.

The Joxy Look and Feel is a "skin" to let Java Swing applications look like the Oxygen theme. Joxy is not an application itself, but a skin for other programs. For installation instructions, please see Joxy's website. Questions about Joxy can be asked in the Discussion section.

Files that can be overloaded include: .BloodyProfanity/conf/sarcasm.yaml # random fail messages, begin every line with '-' (see yaml docs for more) .BloodyProfanity/img/bg.png .BloodyProfanity/img/error.png Other settings can be changed by editing the globals near the top of locker.py. REQUIREMENTS: KDE, PyYAML, Subprocess32, wxPython, fprintd and of course Python.
