## Implemented Interfaces

GtkFrame implements AtkImplementorIface and GtkBuildable.

## Includes

    #include <gtk/gtk.h>

## Description

The frame widget is a bin that surrounds its child with a decorative frame and an optional label. If present, the label is drawn in a gap in the top side of the frame. The position of the label can be controlled with `gtk_frame_set_label_align()`.

### GtkFrame as GtkBuildable

The GtkFrame implementation of the GtkBuildable interface supports placing a child in the label position by specifying “label” as the “type” attribute of a <child> element. A normal content child can be specified without specifying a <child> type attribute.

An example of a UI definition fragment with GtkFrame:

    1
    2
    3
    4
    5
    6
    7
    8
    <object class="GtkFrame">
      <child type="label">
        <object class="GtkLabel" id="frame-label"/>
      </child>
      <child>
        <object class="GtkEntry" id="frame-content"/>
      </child>
    </object>

### CSS nodes

    ├── border[.flat]
    ├── <label widget>
    ╰── <child>

GtkFrame has a main CSS node named “frame” and a subnode named “border”. The “border” node is used to draw the visible border. You can set the appearance of the border using CSS properties like “border-style” on the “border” node.

The border node can be given the style class “.flat”, which is used by themes to disable drawing of the border. To do this from code, call `gtk_frame_set_shadow_type()` with `GTK_SHADOW_NONE` to add the “.flat” class or any other shadow type to remove it.

## Functions

### gtk_frame_new ()

    GtkWidget *
    gtk_frame_new (const gchar *label);

Creates a new GtkFrame, with optional label `label` . If `label` is `NULL`, the label is omitted.

#### Parameters

label | the text to use as the label of the frame. | [allow-none]

#### Returns

a new GtkFrame widget

### gtk_frame_set_label ()

    void
    gtk_frame_set_label (GtkFrame *frame,
                         const gchar *label);

Removes the current “label-widget”. If `label` is not `NULL`, creates a new GtkLabel with that text and adds it as the “label-widget”.

#### Parameters

frame | a GtkFrame |
label | the text to use as the label of the frame. | [allow-none]

### gtk_frame_set_label_widget ()

    void
    gtk_frame_set_label_widget (GtkFrame *frame,
                                GtkWidget *label_widget);

Sets the “label-widget” for the frame. This is the widget that will appear embedded in the top edge of the frame as a title.

#### Parameters

frame | a GtkFrame |
label_widget | the new label widget. | [nullable]

### gtk_frame_set_label_align ()

    void
    gtk_frame_set_label_align (GtkFrame *frame,
                               gfloat xalign,
                               gfloat yalign);

Sets the alignment of the frame widget’s label. The default values for a newly created frame are 0.0 and 0.5.

#### Parameters

frame | a GtkFrame |
xalign | The position of the label along the top edge of the widget. A value of 0.0 represents left alignment; 1.0 represents right alignment. |
yalign | The y alignment of the label. A value of 0.0 aligns under the frame; 1.0 aligns above the frame. If the values are exactly 0.0 or 1.0 the gap in the frame won’t be painted because the label will be completely above or below the frame. |

### gtk_frame_set_shadow_type ()

    void
    gtk_frame_set_shadow_type (GtkFrame *frame,
                               GtkShadowType type);

Sets the “shadow-type” for `frame` , i.e. whether it is drawn without (`GTK_SHADOW_NONE`) or with (other values) a visible border. Values other than `GTK_SHADOW_NONE` are treated identically by GtkFrame. The chosen type is applied by removing or adding the .flat class to the CSS node named border.

#### Parameters

frame | a GtkFrame |
type | the new GtkShadowType |

### gtk_frame_get_label ()

    const gchar *
    gtk_frame_get_label (GtkFrame *frame);

If the frame’s label widget is a GtkLabel, returns the text in the label widget. (The frame will have a GtkLabel for the label widget if a non-`NULL` argument was passed to `gtk_frame_new()`.)

#### Parameters

frame | a GtkFrame |

#### Returns

the text in the label, or `NULL` if there was no label widget or the lable widget was not a GtkLabel. This string is owned by GTK+ and must not be modified or freed.

[nullable]

### gtk_frame_get_label_align ()

    void
    gtk_frame_get_label_align (GtkFrame *frame,
                               gfloat *xalign,
                               gfloat *yalign);

Retrieves the X and Y alignment of the frame’s label. See `gtk_frame_set_label_align()`.

#### Parameters

frame | a GtkFrame |
xalign | location to store X alignment of frame’s label, or `NULL`. | [out][allow-none]
yalign | location to store X alignment of frame’s label, or `NULL`. | [out][allow-none]

### gtk_frame_get_label_widget ()

    GtkWidget *
    gtk_frame_get_label_widget (GtkFrame *frame);

Retrieves the label widget for the frame. See `gtk_frame_set_label_widget()`.

#### Parameters

frame | a GtkFrame |

#### Returns

the label widget, or `NULL` if there is none.

[nullable][transfer none]

### gtk_frame_get_shadow_type ()

    GtkShadowType
    gtk_frame_get_shadow_type (GtkFrame *frame);

Retrieves the shadow type of the frame. See `gtk_frame_set_shadow_type()`.

#### Parameters

frame | a GtkFrame |

#### Returns

the current shadow type of the frame.
