CairoTexture

Object Hierarchy:

public class CairoTexture : Texture, Implementor, Animatable, Scriptable

The CairoTexture struct contains only private data.

Namespace: Clutter

Package: clutter-1.0

public bool auto_resize { set; get; }
Controls whether the CairoTexture should automatically resize the Cairo surface whenever the actor's allocation changes. If auto_resize is set to true the surface contents will also be invalidated automatically.
public uint surface_height { set; get; }
The height of the Cairo surface used by the CairoTexture actor, in pixels.
public uint surface_width { set; get; }
The width of the Cairo surface used by the CairoTexture actor, in pixels.

public CairoTexture (uint width, uint height)
Creates a new CairoTexture actor, with a surface of width by height pixels.

public void clear ()
Clears self's internal drawing surface, so that the next upload will replace the previous contents of the CairoTexture rather than adding to it.
public Context create ()
Creates a new Cairo context for the cairo texture. It is similar to using create_region with x_offset and y_offset of 0, width equal to the cairo texture surface width and height equal to the cairo texture surface height.
public Context create_region (int x_offset, int y_offset, int width, int height)
Creates a new Cairo context that will updat the region defined by x_offset, y_offset, width and height.
public bool get_auto_resize ()
Retrieves the value set using set_auto_resize.
public void get_surface_size (out uint width, out uint height)
Retrieves the surface width and height for self.
public void invalidate ()
Invalidates the whole surface of a CairoTexture.
public void invalidate_rectangle (RectangleInt? rect)
Invalidates a rectangular region of a CairoTexture .
public void set_auto_resize (bool value)
Sets whether the CairoTexture should ensure that the backing Cairo surface used matches the allocation assigned to the actor. If the allocation changes, the contents of the CairoTexture will also be invalidated automatically.
public void set_surface_size (uint width, uint height)
Resizes the Cairo surface used by self to width and height.

public virtual Surface create_surface (uint width, uint height)
The create_surface signal is emitted when a CairoTexture news its surface (re)created, which happens either when the Cairo context is created with create or create_region, or when the surface is resized through set_surface_size.
public virtual bool draw (Context cr)
The draw signal is emitted each time a CairoTexture has been invalidated.
