signal callback delegate or function to connect

x the x coordinate of the cursor position where the request has been emitted, relative to widget's left side (optional)
y the y coordinate of the cursor position where the request has been emitted, relative to widget's top (optional)
keyboardMode true if the tooltip was triggered using the keyboard (optional)
tooltip a gtk.tooltip.Tooltip (optional)
widget the instance the signal is connected to (optional)
Returns true if tooltip should be shown right now, false otherwise.

Signal ID
Connect to QueryTooltip signal.
Emitted when the widget’s tooltip is about to be shown.
This happens when the propertyGtk.Widget:has-tooltip property 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.
