GtkFrame

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:

CSS nodes

<object class="GtkFrame">
  <child type="label">
    <object class="GtkLabel" id="frame-label"/>
  </child>
  <child>
    <object class="GtkEntry" id="frame-content"/>
  </child>
</object>

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.

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,
                           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.

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.

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 ()

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().

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().
