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.
Example 1. Copying selected text in an EphyEmbed
#include <ephy-embed.h>
#include <ephy-command-manager.h>
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 |

"command-changed" signalvoid user_function (EphyCommandManager *manager, gchar *command, gpointer user_data) : Run First
The ::command-changed signal is emitted when command has changed from being
available to unavailable, or vice-versa. The new availability can be tested
with ephy_command_manager_can_do_command().
