Description

The AgsSeekable interface gives you the AgsSeekable::seek() signal what notifies about changed offset of pattern or notation.

AGS_TYPE_SEEKABLE

#define AGS_TYPE_SEEKABLE                    (ags_seekable_get_type())

AGS_TYPE_SEEK_TYPE

#define AGS_TYPE_SEEK_TYPE                   (ags_seek_type_get_type())

AgsSeekable

typedef struct _AgsSeekable AgsSeekable;

Signal Details

The “seek” signal

void
user_function (AgsSeekable *seekable,
               gint64       offset,
               guint        whence,
               gpointer     user_data)

The ::seek signal notifies about changed position of sequencer.

Parameters

seekable

the GObject sub-type implementing AgsSeekable

  

offset

the offset

  

whence

the direction, see AgsSeekType

  

user_data

user data set when the signal handler was connected.

  

Flags: Run Last
