An event handler for the paint event on the window. Not working in Gecko-based applications currently, see Notes section!
funcRefis a handler function.
onpaint doesn't work currently, and it is questionable whether this event is going to work at all, see bug 239074.
The paint event is raised when the window is rendered. This event occurs after the load event for a window, and reoccurs each time the window needs to be re-rendered, as when another window obscures it and is then cleared away.
DOM Level 0. Not part of any standard.
