- Subject: [gtk+] GtkEntryBuffer holds text for GtkEntry
- Date: Thu, 9 Jul 2009 01:49:16 +0000 (UTC)
commit eab02f697a29f2bfd388f6318adf18e2936e7e96
Author: Stef Walter <stef memberwebs com>
Date: Wed Jul 8 20:41:53 2009 -0500
GtkEntryBuffer holds text for GtkEntry
Adds a 'model' type buffer for GtkEntry in which the actual
textual data is stored. GtkEntryBuffer can be subclassed.
Among other things, this allows GtkEntry to be used for secrets
that need to be stored in non-pageable memory. It also allows
buffers to be shared by entries.
See bug #576801.

+ *
+ * The #GtkEntryBuffer class contains the actual text displayed in a
+ * #GtkEntry widget.
+ *
+ * A single #GtkEntryBuffer object can be shared by multiple #GtkEntry
+ * widgets which will then share the same text content, but not the cursor
+ * position, visibility attributes, icon etc.
+ *
+ * #GtkEntryBuffer may be derived from. Such a derived class might allow
+ * text to be stored in an alternate location, such as non-pageable memory,
+ * useful in the case of important passwords. Or a derived class could
+ * integrate with an application's concept of undo/redo.
+ *
