Interface

GcrUiViewer

Description [src]

interface GcrUi.Viewer : Gtk.Widget

An abstract interface that represents a widget that can hold various renderers and display their contents.

The interaction between GcrRenderer and GcrViewer is not stable yet, and so viewers cannot be implemented outside the Gcr library at this time.

Use the gcr_viewer_new() and gcr_viewer_new_scrolled() to get default implementations of viewers.

Prerequisite

In order to implement Viewer, your type must inherit from GtkWidget.

Functions

gcr_viewer_new

Get an implementation of GcrViewer that supports a view of multiple renderers.

gcr_viewer_new_scrolled

Get an implementation of GcrViewer that supports a scrolled view of multiple renderers.

Instance methods

gcr_viewer_add_renderer

Add a renderer to this viewer.

gcr_viewer_count_renderers

Get the number of renderers present in the viewer.

gcr_viewer_get_renderer

Get a pointer to the renderer at the given index. It is an error to request an index that is out of bounds.

gcr_viewer_insert_renderer

Insert a renderer at a specific point in the viewer.

gcr_viewer_remove_renderer

Remove a renderer from this viewer.
