A GcrRenderer is an interface that's implemented by renderers which wish to render data to a GcrViewer.
The interaction between GcrRenderer and GcrViewer is not stable yet, and so new renderers cannot be implemented outside the Gcr library at this time.
To lookup a renderer for a given set of attributes, use the gcr_renderer_create()
function. This will create and initialize a renderer that's capable of viewing
the data in those attributes.
struct GcrRendererIface { GTypeInterface parent; /* signals */ void (*data_changed) (GcrRenderer *self); /* virtual */ void (*render) (GcrRenderer *self, GcrViewer *viewer); };
The interface for GcrRenderer
GTypeInterface |
The parent interface |
The GcrRenderer::data-changed signal | |
A virtual method to render the contents. |
GcrRenderer * gcr_renderer_create (const gchar *label
,GckAttributes *attrs
);
Create and initialize a renderer for the given attributes and label. These
renderers should have been preregistered via gcr_renderer_register()
.
|
The label for the renderer |
|
The attributes to render |
Returns : |
A new renderer, or NULL if no renderer matched the attributes.
The render should be released with g_object-unref() . |
void gcr_renderer_register (GType renderer_type
,GckAttributes *attrs
);
Register a renderer to be created when matching attributes are passed to
gcr_renderer_create()
.
|
The renderer class type |
|
The attributes to match |
void gcr_renderer_render (GcrRenderer *self
,GcrViewer *viewer
);
Render the contents of the renderer to the given viewer.
|
The renderer |
|
The viewer to render to. |
void gcr_renderer_emit_data_changed (GcrRenderer *self
);
Emit the GcrRenderer::data-changed signal on the renderer. This is used by renderer implementations.
