Prerequisites

GcrRenderer requires GObject.

Known Implementations

GcrRenderer is implemented by GcrCertificateRenderer and GcrKeyRenderer.

Description

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.

Functions

gcr_renderer_create ()

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().

Parameters

label

The label for the renderer.

[allow-none]

attrs

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().

[transfer full][allow-none]


gcr_renderer_register ()

void
gcr_renderer_register (GType renderer_type,
                       GckAttributes *attrs);

Register a renderer to be created when matching attributes are passed to gcr_renderer_create().

Parameters

renderer_type

The renderer class type

 

attrs

The attributes to match

 

gcr_renderer_get_attributes ()

GckAttributes *
gcr_renderer_get_attributes (GcrRenderer *self);

Get the PKCS#11 attributes, if any, set for this renderer to display.

Parameters

self

The renderer

 

Returns

the attributes, owned by the renderer.

[allow-none][transfer none]


gcr_renderer_set_attributes ()

void
gcr_renderer_set_attributes (GcrRenderer *self,
                             GckAttributes *attrs);

Set the PKCS#11 attributes for this renderer to display.

Parameters

self

The renderer

 

attrs

attributes to set.

[allow-none]

gcr_renderer_popuplate_popup ()

void
gcr_renderer_popuplate_popup (GcrRenderer *self,
                              GcrViewer *viewer,
                              GtkMenu *menu);

Called by GcrViewer when about to display a popup menu for the content displayed by the renderer. The renderer can add a menu item if desired.

Parameters

self

The renderer

 

viewer

The viewer that is displaying a popup

 

menu

The popup menu being displayed

 

gcr_renderer_render_view ()

void
gcr_renderer_render_view (GcrRenderer *self,
                          GcrViewer *viewer);

Render the contents of the renderer to the given viewer.

Parameters

self

The renderer

 

viewer

The viewer to render to.

 

gcr_renderer_emit_data_changed ()

void
gcr_renderer_emit_data_changed (GcrRenderer *self);

Emit the “data-changed” signal on the renderer. This is used by renderer implementations.

Parameters

self

The renderer

 

gcr_renderer_register_well_known ()

void
gcr_renderer_register_well_known (void);

Register all the well known renderers for certificates and keys known to the Gcr library.

Types and Values

GcrRenderer

typedef struct _GcrRenderer GcrRenderer;

A renderer.


struct GcrRendererIface

struct GcrRendererIface {
	GTypeInterface parent;

	/* signals */
	void (*data_changed) (GcrRenderer *self);

	/* virtual */
	void (*render_view) (GcrRenderer *self, GcrViewer *viewer);

	void (*populate_popup) (GcrRenderer *self, GcrViewer *viewer, GtkMenu *menu);
};
