Widget.addOnQueryTooltip

Emitted when #GtkWidget:has-tooltip is %TRUE and the hover timeout has expired with the cursor hovering "above" @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. 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.
