Signal ID
Connect to QueryTooltip signal.
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.
