gtk:style-context-invalidate (context)

context -- a gtk:style-context object

Invalidates style context information, so it will be reconstructed again. If you are using a style context returned from the gtk:widget-style-context function, you do not need to call this yourself. The gtk:style-context-invalidate function has been deprecated since version 3.12 and should not be used in newly written code. Style contexts are invalidated automatically.
