Emitted when the "gtk-tooltip-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 "tooltip-text" in preference.
TRUE if the tooltip was trigged using the keyboard
TRUE if tooltip should be shown right now, FALSE otherwise.
