ClutterTexture is full of side effects that have been picked up over the years; they make improving ClutterTexture harder than necessary, as well as making subclassing impossible without introducing weird behaviours in the child classes as well. Since Clutter 1.10 we have the ClutterImage content type, which is side-effects free, given that it just paints texture data using the state of the actor. Sadly, we still have subclasses of ClutterTexture, both deprecated and not, so we cannot deprecate ClutterTexture right out; the type and structures will still be available, like we do for ClutterGroup, but the whole API should be moved to the deprecated section, waiting for the time in which we can get rid of it all.

|
* @Title: ClutterGLXTexturePixmap
|
|
* @short_description: A texture which displays the content of an X Pixmap
|
|
* @Deprecated: 1.4: Use #ClutterX11TexturePixmap instead.
|
|
*
|
|
* #ClutterGLXTexturePixmap is a class for displaying the content of an
|
|
* X Pixmap as a ClutterActor. Used together with the X Composite extension,
|
|
* it allows to display the content of X Windows inside Clutter.
|
|
*
|
|
* This class used to be necessary to use the
|
|
* GLX_EXT_texture_from_pixmap extension to get fast texture
|
|
* updates. However since Clutter 1.4 the handling of this extension
|
|
* has moved down to Cogl. ClutterX11TexturePixmap and
|
|
* ClutterGLXTexturePixmap are now equivalent and either one of them
|
|
* may use the extension if it is possible.
