# Method GTK2.G.Object()->signal_connect()

Method signal_connect

  ``int` signal_connect(`string` `signal`, `function`(:`void`) `callback`, `mixed`|`void` `callback_arg`, `string`|`void` `detail`, `int`|`void` `connect_before`)`

Description

  Connect a signal to a pike function. The function will be called with the last argument to this function as its last argument (defaults to 0); the first argument is always the widget, and any other arguments are the ones supplied by GTK. If connect_before is nonzero, the callback will be called prior to the normal handling of the signal (and can return true to suppress that handling), otherwise it will be called after.

  The return value of this function can be used to remove a signal with signal_disconnect(), and block and unblock the signal with signal_block() and signal_unblock().
