EphyCommandManager
Performs commands, such as cut/copy/paste
An #EphyCommandManager is an interface to an #EphyEmbed which is used to perform
commands, such as cut/copy/paste. To perform any command, use
ephy_command_manager_do_command(). To test the availability of a command, use
ephy_command_manager_can_do_command(). The availability of commands depends on
the selection and actions previously performed in the #EphyEmbed. For instance,
%cmd_copy is only available if text has been selected; %cmd_undo is only
available if the user has a text input focused and has typed or erased some of
its text.
Copying selected text in an #EphyEmbed
#]]>
#
static void
copy_selected_text (EphyEmbed *embed)
{
EphyCommandManager *manager;
manager = EPHY_COMMAND_MANAGER (embed);
g_return_if_fail (EPHY_IS_COMMAND_MANAGER (manager));
if (!ephy_command_manager_can_do_command (manager, "cmd_copy")) return;
ephy_command_manager_do_command (manager, "cmd_copy");

The #EphyCommandManager interface can perform any command which is defined in
Mozilla. However, for purposes of abstraction, only a certain subset of commands
should be used:
Available Commands
cmd_copy
Copies selected text
cmd_cut
Cuts selected text.
cmd_paste
Pastes text from the clipboard (for example, into a text entry)
cmd_undo
Undoes the last action (for example, typing text into a text
entry
cmd_redo
Redoes previously %undone actions (for example, in a
text entry)
