## Description

ClutterText is an actor that displays custom text using Pango as the text rendering engine.

ClutterText also allows inline editing of the text if the actor is set editable using `clutter_text_set_editable()`.

Selection using keyboard or pointers can be enabled using `clutter_text_set_selectable()`.

ClutterText is available since Clutter 1.0

Sets the contents of a ClutterText actor.

If the "use-markup" property was set to `TRUE` it will be reset to `FALSE` as a side effect. If you want to maintain the "use-markup" you should use the `clutter_text_set_markup()` function instead

`self` : | a ClutterText
`text` : | the text to set. Passing `NULL` is the same as passing "" (the empty string). [allow-none]

Since 1.0

### clutter_text_set_markup ()

    void                clutter_text_set_markup             (ClutterText *self,

Sets `markup` as the contents of a ClutterText.

This is a convenience function for setting a string containing Pango markup, and it is logically equivalent to:

    1
    2
    3
    /* the order is important */
    clutter_text_set_text (CLUTTER_TEXT (actor), markup);
    clutter_text_set_use_markup (CLUTTER_TEXT (actor), TRUE);

`self` : | a ClutterText
`markup` : | a string containing Pango markup. Passing `NULL` is the same as passing "" (the empty string). [allow-none]

### clutter_text_get_text ()

    const gchar *       clutter_text_get_text               (ClutterText *self);

If you need a copy of the contents for manipulating, either use `g_strdup()` on the returned string, or use:

    1
    copy = clutter_text_get_chars (text, 0, -1);

Which will return a newly allocated string.

If the ClutterText actor is empty, this function will return an empty string, and not `NULL`.

`self` : | a ClutterText
Returns : | the contents of the actor. The returned string is owned by the ClutterText actor and should never be modified or freed. [transfer none]

Since 1.0

Sets whether a ClutterText actor should be activatable.

An activatable ClutterText actor will emit the "activate" signal whenever the 'Enter' (or 'Return') key is pressed; if it is not activatable, a new line will be appended to the current content.

An activatable ClutterText must also be set as editable using `clutter_text_set_editable()`.

`self` : | a ClutterText
`activatable` : | whether the ClutterText actor should be activatable

Since 1.0

### clutter_text_get_activatable ()

### The `"single-line-mode"` property

      "single-line-mode"         gboolean              : Read / Write

Whether the ClutterText actor should be in single line mode or not. A single line ClutterText actor will only contain a single line of text, scrolling it in case its length is bigger than the allocated size.

Setting this property will also set the "activatable" property as a side-effect.

The "single-line-mode" property is used only if the "editable" property is set to `TRUE`.

Default value: FALSE

Since 1.0

### The `"text"` property

      "text"                     gchar*                : Read / Write

The text to render inside the actor.

Default value: ""

Since 1.0

### The `"use-markup"` property

      "use-markup"               gboolean              : Read / Write

Whether the text includes Pango markup.

For more informations about the Pango markup format, see `pango_layout_set_markup()` in the Pango documentation.

### Note

It is not possible to round-trip this property between `TRUE` and `FALSE`. Once a string with markup has been set on a ClutterText actor with :use-markup set to `TRUE`, the markup is stripped from the string.

Default value: FALSE

## Signal Details

### The `"activate"` signal

    void                user_function                      (ClutterText *self,
                                                            gpointer     user_data)      : Run Last

The ::activate signal is emitted each time the actor is 'activated' by the user, normally by pressing the 'Enter' key. The signal is emitted only if "activatable" is set to `TRUE`.

`self` : | the ClutterText that emitted the signal
`user_data` : | user data set when the signal handler was connected.

Since 1.0

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

    void                user_function                      (ClutterText     *self,
                                                            ClutterGeometry *geometry,
                                                            gpointer         user_data)      : Run Last

The ::cursor-event signal is emitted whenever the cursor position changes inside a ClutterText actor. Inside `geometry` it is stored the current position and size of the cursor, relative to the actor itself.

`self` : | the ClutterText that emitted the signal
`geometry` : | the coordinates of the cursor
`user_data` : | user data set when the signal handler was connected.

Since 1.0

### The `"delete-text"` signal

    void                user_function                      (ClutterText *self,
                                                            gint         start_pos,
                                                            gint         end_pos,
                                                            gpointer     user_data)      : Action

This signal is emitted when text is deleted from the actor by the user. It is emitted before `self` text changes.

`self` : | the ClutterText that emitted the signal
`start_pos` : | the starting position
`end_pos` : | the end position
`user_data` : | user data set when the signal handler was connected.

Since 1.2

### The `"insert-text"` signal

    void                user_function                      (ClutterText *self,
                                                            gchar       *new_text,
                                                            gint         new_text_length,
                                                            gpointer     position,
                                                            gpointer     user_data)            : Action

This signal is emitted when text is inserted into the actor by the user. It is emitted before `self` text changes.

`self` : | the ClutterText that emitted the signal
`new_text` : | the new text to insert
`new_text_length` : | the length of the new text, in bytes, or -1 if new_text is nul-terminated
`position` : | the position, in characters, at which to insert the new text. this is an in-out parameter. After the signal emission is finished, it should point after the newly inserted text.
`user_data` : | user data set when the signal handler was connected.

Since 1.2

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

    void                user_function                      (ClutterText *self,
                                                            gpointer     user_data)      : Run Last

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

`self` : | the ClutterText that emitted the signal
`user_data` : | user data set when the signal handler was connected.
