Plugins

Someone can explain me in brief how i can create and use plugins ?

For example if i want to create e new type of button what should i do ?

First of all there's Demo_PluginStrangeButton repository. There shown how to use plugins.

What do you mean by "new type of button"? If it have non-standard logic then yes, you need to create your own widget. If you need button that have standard logic but looks different you need only create skin.

Ok i've got it.
