Instance methods

gdk_pixbuf_animation_iter_advance

Possibly advances an animation to a new frame.

gdk_pixbuf_animation_iter_get_delay_time

Gets the number of milliseconds the current pixbuf should be displayed, or -1 if the current pixbuf should be displayed forever.

gdk_pixbuf_animation_iter_get_pixbuf

Gets the current pixbuf which should be displayed.

gdk_pixbuf_animation_iter_on_currently_loading_frame

Used to determine how to respond to the area_updated signal on GdkPixbufLoader when loading an animation.

GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Class structure

struct GdkPixbufPixbufAnimationIterClass {
  GObjectClass parent_class;
  int (* get_delay_time) (
    GdkPixbufAnimationIter* iter
  );
  GdkPixbuf* (* get_pixbuf) (
    GdkPixbufAnimationIter* iter
  );
  gboolean (* on_currently_loading_frame) (
    GdkPixbufAnimationIter* iter
  );
  gboolean (* advance) (
    GdkPixbufAnimationIter* iter,
    const GTimeVal* current_time
  );
  
}

Modules supporting animations must derive a type from GdkPixbufAnimationIter, providing suitable implementations of the virtual functions.

Class members

parent_class: GObjectClass: The parent class.
get_delay_time: int (* get_delay_time) ( GdkPixbufAnimationIter* iter ): Returns the time in milliseconds that the current frame should be shown.
get_pixbuf: GdkPixbuf* (* get_pixbuf) ( GdkPixbufAnimationIter* iter ): Returns the current frame.
on_currently_loading_frame: gboolean (* on_currently_loading_frame) ( GdkPixbufAnimationIter* iter ): Returns whether the current frame of iter is being loaded.
advance: gboolean (* advance) ( GdkPixbufAnimationIter* iter, const GTimeVal* current_time ): Advances the iterator to current_time, possibly changing the current frame.
