Description

Clutter provides a set of predefined ClutterPaintNode implementations that cover all the state changes available.

Functions

clutter_color_node_new ()

ClutterPaintNode *
clutter_color_node_new (const ClutterColor *color);

Creates a new ClutterPaintNode that will paint a solid color fill using color .

Parameters

color

the color to paint, or NULL.

[allow-none]

Returns

the newly created ClutterPaintNode. Use clutter_paint_node_unref() when done.

[transfer full]

Since: 1.10


clutter_texture_node_new ()

ClutterPaintNode *
clutter_texture_node_new (CoglTexture *texture,
                          const ClutterColor *color,
                          ClutterScalingFilter min_filter,
                          ClutterScalingFilter mag_filter);

Creates a new ClutterPaintNode that will paint the passed texture .

This function will take a reference on texture , so it is safe to call cogl_object_unref() on texture when it returns.

The color must not be pre-multiplied with its ClutterColor.alpha channel value; if color is NULL, a fully opaque white color will be used for blending.

Parameters

texture

a CoglTexture

 

color

a ClutterColor used for blending, or NULL.

[allow-none]

min_filter

the minification filter for the texture

 

mag_filter

the magnification filter for the texture

 

Returns

the newly created ClutterPaintNode. Use clutter_paint_node_unref() when done.

clutter_pipeline_node_new ()

ClutterPaintNode *
clutter_pipeline_node_new (CoglPipeline *pipeline);

Creates a new ClutterPaintNode that will use the pipeline to paint its contents.

This function will acquire a reference on the passed pipeline , so it is safe to call cogl_object_unref() when it returns.

Parameters

pipeline

a Cogl pipeline state object, or NULL.

[allow-none]

Returns

the newly created ClutterPaintNode. Use clutter_paint_node_unref() when done.

Since: 1.10


clutter_text_node_new ()

ClutterPaintNode *
clutter_text_node_new (PangoLayout *layout,
                       const ClutterColor *color);

Creates a new ClutterPaintNode that will paint a PangoLayout with the given color.

This function takes a reference on the passed layout , so it is safe to call g_object_unref() after it returns.

Parameters

layout

a PangoLayout, or NULL.

[allow-none]

color

the color used to paint the layout, or NULL.

[allow-none]

Returns

the newly created ClutterPaintNode. Use clutter_paint_node_unref() when done.

[transfer full]

Since: 1.10


clutter_clip_node_new ()

ClutterPaintNode *
clutter_clip_node_new (void);

Creates a new ClutterPaintNode that will clip its child nodes to the 2D regions added to it.

Returns

the newly created ClutterPaintNode. Use clutter_paint_node_unref() when done.
