html-widget-over-link

Arguments: html-widget message

This generic function is implemented on Linux only

This generic function is called when the mouse cursor moves onto or off of a link in an html-widget. The default method calls the widget's on-link-message function if it has one, and otherwise does nothing. An application could add methods for an html-widget subclass.

html-widget is the html-widget under the mouse cursor.

message is a string indicating what is now under the mouse cursor. When the mouse cursor has just moved onto a link, it will be the URL of the link. When mouse cursor has just moved off of a link, it will be the null string. Typically an application would display this string in a common-status-bar.

This generic function will not be called on Windows, where Common Graphics does not know when the mouse cursor has moved onto a link.
