Emitted when the hover timeout has expired with the
cursor hovering above @status_icon; or emitted when @status_icon got
focus in keyboard mode.
Using the given coordinates, the signal handler should determine
whether a tooltip should be shown for @status_icon. If this is
the case %TRUE should be returned, %FALSE otherwise. Note that if
@keyboard_mode is %TRUE, the values of @x and @y are undefined and
should not be used.
The signal handler is free to manipulate @tooltip with the therefore
destined function calls.
Whether this signal is emitted is platform-dependent.
For plain text tooltips, use #GtkStatusIcon:tooltip-text in preference.
