### Warning

`clutter_entry_handle_key_event` has been deprecated since version 0.8 and should not be used in newly-written code. The key events will automatically be handled when giving the key focus to an entry using `clutter_stage_set_key_focus()`.

This function will handle a ClutterKeyEvent, like those returned in a key-press/release-event, and will translate it for the `entry`. This includes non-alphanumeric keys, such as the arrows keys, which will move the input cursor. You should use this function inside a handler for the ClutterStage::key-press-event or ClutterStage::key-release-event.

`entry` : | a ClutterEntry
`kev` : | a ClutterKeyEvent

Since 0.4

### clutter_entry_insert_unichar ()

Deletes a sequence of characters. The characters that are deleted are those characters at positions from `start_pos` up to, but not including, `end_pos`. If `end_pos` is negative, then the characters deleted will be those characters from `start_pos` to the end of the text.

`visible` : | whether the input cursor should be visible

Since 0.4

### clutter_entry_get_visible_cursor ()

    gboolean            clutter_entry_get_visible_cursor    (ClutterEntry *entry);

Sets whether the contents of the entry are visible or not. When visibility is set to `FALSE`, characters are displayed as the invisible char, and will also appear that way when the text in the entry widget is copied elsewhere.

The default invisible char is the asterisk '*', but it can be changed with `clutter_entry_set_invisible_char()`.

`entry` : | a ClutterEntry
`visible` : | `TRUE` if the contents of the entry are displayed as plaintext.

Sets the character to use in place of the actual text when `clutter_entry_set_visibility()` has been called to set text visibility to `FALSE`. i.e. this is the character used in "password mode" to show the user how many characters have been typed. The default invisible char is an asterisk ('*'). If you set the invisible char to 0, then the user will get no feedback at all; there will be no text on the screen as they type.

`entry` : | a ClutterEntry
`wc` : | a Unicode character

Sets the maximum allowed length of the contents of the actor. If the current contents are longer than the given length, then they will be truncated to fit.

`entry` : | a ClutterEntry
`max` : | the maximum number of characters allowed in the entry; 0 to disable or -1 to set the length of the current string

## Signal Details

### The `"activate"` signal

    void                user_function                      (ClutterEntry *entry,
                                                            gpointer      user_data)      : Run Last

The ::activate signal is emitted each time the entry is 'activated' by the user, normally by pressing the 'Enter' key.

`entry` : | the actor which received the event
`user_data` : | user data set when the signal handler was connected.

Since 0.4

### The `"cursor-event"` signal

    void                user_function                      (ClutterEntry    *entry,
                                                            ClutterGeometry *geometry,
                                                            gpointer         user_data)      : Run Last

The ::cursor-event signal is emitted each time the input cursor's geometry changes, this could be a positional or size change. If you would like to implement your own input cursor, set the cursor-visible property to `FALSE`, and connect to this signal to position and size your own cursor.

`entry` : | the actor which received the event
`geometry` : | a ClutterGeometry
`user_data` : | user data set when the signal handler was connected.

Since 0.4

### The `"text-changed"` signal

    void                user_function                      (ClutterEntry *entry,
                                                            gpointer      user_data)      : Run Last

The ::text-changed signal is emitted after `entry`'s text changes

`entry` : | the actor which received the event
`user_data` : | user data set when the signal handler was connected.
