Frame

open class Frame : Bin, FrameProtocol

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:

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

CSS nodes

(plain Language Example):

frame
├── 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.

The Frame type acts as a reference-counted owner of an underlying GtkFrame instance. It provides the methods that can operate on this data type through FrameProtocol conformance. Use Frame as a strong reference or owner of a GtkFrame instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Frame instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkFrame>)

    Parameters

    op

    pointer to the underlying object

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Frame instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkFrame>)

    Parameters

    op

    pointer to the underlying object
