## Implemented Interfaces

MxExpander implements ClutterContainer, ClutterScriptable, ClutterAnimatable, AtkImplementorIface, MxStylable and MxFocusable.

## Properties

      "expanded"                 gboolean              : Read / Write
      "label"                    gchar*                : Read / Write

## Signals

      "expand-complete"                                : Run Last

## Description

MxExpander is a single child container that allows the user to show or hide its child. It displays a clickable bar (with a text label), which (by default) when clicked toggles display of the child.

## Details

### MxExpander

    typedef struct _MxExpander MxExpander;

The contents of the this structure are private and should only be accessed through the public API.

### MxExpanderClass

    typedef struct {
      MxBinClass parent_class;

      /* signals */
      void (* expand_complete)   (MxExpander *expander);

      /* padding for future expansion */
      void (*_padding_0) (void);
      void (*_padding_1) (void);
      void (*_padding_2) (void);
      void (*_padding_3) (void);
      void (*_padding_4) (void);
    } MxExpanderClass;

### mx_expander_new ()

    ClutterActor *      mx_expander_new                     (void);

Creates a new MxExpander

Returns : | the newly allocated MxExpander

### mx_expander_set_label ()

    void                mx_expander_set_label               (MxExpander *expander,
                                                             const gchar *label);

Sets the text displayed as the title of the expander

`expander` : | A MxExpander
`label` : | string to set as the expander label

### mx_expander_get_expanded ()

    gboolean            mx_expander_get_expanded            (MxExpander *expander);

Get the current state of the expander (the value of "expanded")

`expander` : | a MxExpander
Returns : | TRUE if the expander is open, FALSE if it is closed

### mx_expander_set_expanded ()

    void                mx_expander_set_expanded            (MxExpander *expander,
                                                             gboolean expanded);

Set the state (the "expanded" property) of the expander. This will cause the expander to open or close.

`expander` : | A MxExpander
`expanded` : | the state of the expander to set

## Property Details

### The `"expanded"` property

      "expanded"                 gboolean              : Read / Write

Indicates that the expander is open or closed.

Default value: FALSE

### The `"label"` property

      "label"                    gchar*                : Read / Write

Expander title label.

Default value: NULL

## Signal Details

### The `"expand-complete"` signal

    void                user_function                      (MxExpander *expander,
                                                            gpointer    user_data)      : Run Last

Emitted after the expand animation finishes. Check the "expanded" property of the MxExpander to determine if the expander is expanded or not.

`expander` : | the object that received the signal
`user_data` : | user data set when the signal handler was connected.
