Signals¶

Name	Short Description

Class Details¶

class Clutter.Content¶

Bases:: GObject.GInterface
Structure:: Clutter.ContentIface

The Clutter.Content structure is an opaque type whose members cannot be acccessed directly.

New in version 1.10.

get_preferred_size()¶

Returns:

True if the content has a preferred size, and False otherwise

width:: return location for the natural width of the content
height:: return location for the natural height of the content

Return type:

(bool, width: float, height: float)

Retrieves the natural size of the self, if any.

The natural size of a Clutter.Content is defined as the size the content would have regardless of the allocation of the actor that is painting it, for instance the size of an image data.

New in version 1.10.

invalidate()¶

Invalidates a Clutter.Content.

This function should be called by Clutter.Content implementations when they change the way a the content should be painted regardless of the actor state.

New in version 1.10.

do_attached(actor) virtual¶

Parameters:: actor (Clutter.Actor) –

do_detached(actor) virtual¶

Parameters:: actor (Clutter.Actor) –

do_get_preferred_size() virtual¶

Returns:

True if the content has a preferred size, and False otherwise

width:: return location for the natural width of the content
height:: return location for the natural height of the content

Return type:

(bool, width: float, height: float)

Retrieves the natural size of the content, if any.

The natural size of a Clutter.Content is defined as the size the content would have regardless of the allocation of the actor that is painting it, for instance the size of an image data.

New in version 1.10.

do_invalidate() virtual¶

Invalidates a Clutter.Content.

This function should be called by Clutter.Content implementations when they change the way a the content should be painted regardless of the actor state.

New in version 1.10.

do_paint_content(actor, node) virtual¶

Parameters:

actor (Clutter.Actor) –
node (Clutter.PaintNode) –

Signal Name:

detached

Flags:

RUN_FIRST

Parameters:
