Gdk.PaintableInterface

Fields

Name	Type	Access	Description
g_iface	GObject.TypeInterface	r
get_current_image	object	r	return a GdkPaintable that does not change over time. This means the GDK_PAINTABLE_STATIC_SIZE and GDK_PAINTABLE_STATIC_CONTENTS flag are set.
get_flags	object	r	Get the flags for this instance. See [enum`Gdk`.PaintableFlags] for details.
get_intrinsic_aspect_ratio	object	r	The preferred aspect ratio for this object or 0 if none. If both [vfunc`Gdk`.Paintable.get_intrinsic_width] and [vfunc`Gdk`.Paintable.get_intrinsic_height] return non-zero values, this function should return the aspect ratio computed from those.
get_intrinsic_height	object	r	The preferred height for this object to be snapshot at or 0 if none. This is purely a hint. The object must still be able to render at any size.
get_intrinsic_width	object	r	The preferred width for this object to be snapshot at or 0 if none. This is purely a hint. The object must still be able to render at any size.
snapshot	object	r	Snapshot the paintable. The given width and height are guaranteed to be larger than 0.0. The resulting snapshot must modify only the area in the rectangle from (0,0) to (width, height). This is the only function that must be implemented for this interface.

Details

class Gdk.PaintableInterface

The list of functions that can be implemented for the GdkPaintable interface.

Note that apart from the [vfunc`Gdk`.Paintable.snapshot] function, no virtual function of this interface is mandatory to implement, though it is a good idea to implement [vfunc`Gdk`.Paintable.get_current_image] for non-static paintables and [vfunc`Gdk`.Paintable.get_flags] if the image is not dynamic as the default implementation returns no flags and that will make the implementation likely quite slow.
