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:

<object class="GtkFrame">
  <child type="label">
    <object class="GtkLabel" id="frame_label"/>
  </child>
  <child>
    <object class="GtkEntry" id="frame_content"/>
  </child>
</object>

CSS nodes

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

GtkFrame has a main CSS node with name “frame”, which is used to draw the visible border. You can set the appearance of the border using CSS properties like “border-style” on this node.

The 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.

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.

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”.

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.

gtk_frame_set_label_align ()

void
gtk_frame_set_label_align (GtkFrame *frame,
                           gfloat xalign);

Sets the X alignment of the frame widget’s label. The default value for a newly created frame is 0.0.

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 main CSS node, frame.

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().)

gtk_frame_get_label_align ()

gfloat
gtk_frame_get_label_align (GtkFrame *frame);

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

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().

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().
