Widget.addOnQueryTooltip

Emitted when "has-tooltip" is TRUE and the "gtk-tooltip-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. TRUE if the tooltip was trigged using the keyboard Since 2.12
