## Description

## Details

### GimpColorArea

    typedef struct _GimpColorArea GimpColorArea;

### enum GimpColorAreaType

    typedef enum
    {
      GIMP_COLOR_AREA_FLAT = 0,
      GIMP_COLOR_AREA_SMALL_CHECKS,
      GIMP_COLOR_AREA_LARGE_CHECKS
    } GimpColorAreaType;

### gimp_color_area_new ()

    GtkWidget*  gimp_color_area_new             (const GimpRGB *color,
                                                 GimpColorAreaType type,
                                                 GdkModifierType drag_mask);

Creates a new GimpColorArea widget.

This returns a preview area showing the color. It handles color DND. If the color changes, the "color_changed" signal is emitted.

`color` : | A pointer to a GimpRGB struct.
`type` : | The type of color area to create.
`drag_mask` : | The event_mask that should trigger drags.
Returns : | Pointer to the new GimpColorArea widget.

### gimp_color_area_set_color ()

    void        gimp_color_area_set_color       (GimpColorArea *area,
                                                 const GimpRGB *color);

Sets `area` to a different `color`.

`area` : | Pointer to a GimpColorArea.
`color` : | Pointer to a GimpRGB struct that defines the new color.

### gimp_color_area_get_color ()

    void        gimp_color_area_get_color       (GimpColorArea *area,
                                                 GimpRGB *color);

Retrieves the current color of the `area`.

`area` : | Pointer to a GimpColorArea.
`color` : | Pointer to a GimpRGB struct that is used to return the color.

### gimp_color_area_has_alpha ()

    gboolean    gimp_color_area_has_alpha       (GimpColorArea *area);

Checks whether the `area` shows transparency information. This is determined via the `area`'s GimpColorAreaType.

`area` : | Pointer to a GimpColorArea.
Returns : | `TRUE` if `area` shows transparency information, `FALSE` otherwise.

### gimp_color_area_set_type ()

    void        gimp_color_area_set_type        (GimpColorArea *area,
                                                 GimpColorAreaType type);

Allows to change the type of `area`. The GimpColorAreaType determines whether the widget shows transparency information and chooses the size of the checkerboard used to do that.

`area` : | Pointer to a GimpColorArea.
`type` : | A GimpColorAreaType.

### gimp_color_area_set_draw_border ()

    void        gimp_color_area_set_draw_border (GimpColorArea *area,
                                                 gboolean draw_border);

The `area` can draw a thin border in the foreground color around itself. This function allows to toggle this behaviour on and off. The default is not draw a border.

`area` : | Pointer to a GimpColorArea.
`draw_border` : | whether to draw a border or not

## Signal Details

### The "color-changed" signal

    void        user_function                  (GimpColorArea *gimpcolorarea,
                                                gpointer       user_data)          : Run first

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