g-signal-query (signal-id)

signal-id -- an unsigned integer with the signal ID of the signal to query information for

A g-signal-query structure with the signal info.

Returns the signal info. Queries the signal system for in-depth information about a specific signal. This function will return signal-specific information. If an invalid signal ID is passed in, the signal-id member is 0. Retrieve information for the "draw" signal of a widget:

(setq query (g-signal-query (g-signal-lookup "show" "GtkWidget")))
=> #<Signal [#36] void GtkWidget.show () [RUN-FIRST]>
(g-signal-query-signal-id query)
=> 36
(g-signal-query-signal-name query)
=> "show"
(g-signal-query-owner-type query)
=> #<GTYPE :name "GtkWidget" :id 18826464>
(g-signal-query-signal-flags query)
=> (:RUN-FIRST)
(g-signal-query-return-type query)
=> #<GTYPE :name "void" :id 4>
(g-signal-query-param-types query)
=> NIL
(g-signal-query-signal-detail query)
=> NIL    

A second example for the "drag-drop" signal of a widget:

(setq query (g-signal-query (g-signal-lookup "drag-drop" "GtkWidget")))
=> #<Signal [#91] gboolean GtkWidget.drag-drop (GdkDragContext, gint, gint, guint) [RUN-LAST]>
(g-signal-query-signal-id query)
=> 91
(g-signal-query-signal-name query)
=> "drag-drop"
(g-signal-query-owner-type query)
=> #<GTYPE :name "GtkWidget" :id 18826464>
(g-signal-query-signal-flags query)
=> (:RUN-LAST)
(g-signal-query-return-type query)
=> #<GTYPE :name "gboolean" :id 20>
(g-signal-query-param-types query)
=> (#<GTYPE :name "GdkDragContext" :id 18798624> #<GTYPE :name "gint" :id 24>
 #<GTYPE :name "gint" :id 24> #<GTYPE :name "guint" :id 28>)
(g-signal-query-signal-detail query)
=> NIL
