## Functions

### 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.

#### Parameters

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` .

#### Parameters

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` .

#### Parameters

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.

#### Parameters

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.

#### Parameters

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.

#### Parameters

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

## Types and Values

### GimpColorArea

    typedef struct _GimpColorArea GimpColorArea;

### enum GimpColorAreaType

The types of transparency display for GimpColorArea.

#### Members

GIMP_COLOR_AREA_FLAT | don't display transparency |
GIMP_COLOR_AREA_SMALL_CHECKS | display transparency using small checks |
GIMP_COLOR_AREA_LARGE_CHECKS | display transparency using large checks |
