show-tooltip

Arguments: widget

This generic function is called internally to show the tooltip of a control. This function is not normally called by an application, but wrapper methods may be added to act when a tooltip is invoked after the mouse pauses over a control. This may be useful, for example, for displaying some other form of help (such as a status-bar message) after the mouse has paused over a control.

Note that this generic function is called even if the show-tooltips configuration option has been turned off. This allows showing some custom form of help for a control without using tooltips, which may be handy if tooltips are considered more annoying than a status-bar message, for example.

See also hide-tooltip.
