Safe to use Component.repaint() outside EDT?

awt, java, swing

Solution

Here is a quote from an official page stating that:

The following JComponent methods are safe to call from any thread: `repaint()`, `revalidate()`, and `invalidate()`. The `repaint()` and `revalidate()` methods queue requests for the event-dispatching thread to call `paint()` and `validate()`, respectively.

EDIT 1 :

Since the previous link mentioned has been shifted. I am posting a new link, though it might take a bit more time to actually know the authenticity of this page, since it appears to be from `Java` though it originated from some `University`'s server, as can be seen from the address bar.
