If you mean WebSwitch componenent - it is exactly isSelected/setSelected methods which retrieve/set the switch state. If you don't see them there - you are probably using older version or I misunderstood which component you are trying to use there.
Documentation right now is mostly limited to a few wiki articles on most complicated things and JavaDoc in the WebLaF sources for everything else. Second one right now is the most reliable source of information as I try to describe every little thing in the code to make it convenient and since the code changes a lot and sometimes wiki articles might get outdated.
You can always look at the source code on GitHub:https://github.com/mgarin/weblaf/blob/m ... witch.java
or by attaching sources to your IDE project.
Also you can always ask any questions here, on GitHub or by directly mailing me
There will be a huge v1.29 update later on which will introduce a lot of new stuff and along with it I am planning to release much more wiki articles. Ideally I want to have at least one on every single component presented in the library.
