public sealed class AspectFrame : Widget, Accessible, Buildable, ConstraintTarget
public sealed class AspectFrame : Widget, Accessible, Buildable, ConstraintTarget
`GtkAspectFrame` preserves the aspect ratio of its child.
The frame can respect the aspect ratio of the child widget, or use its own aspect ratio.
CSS nodes
`GtkAspectFrame` uses a CSS node with name `frame`.
Accessibility
Until GTK 4.10, `GtkAspectFrame` used the `GTK_ACCESSIBLE_ROLE_GROUP` role.
Starting from GTK 4.12, `GtkAspectFrame` uses the `GTK_ACCESSIBLE_ROLE_GENERIC` role.
Namespace: Gtk
Package: gtk4
Content:
Properties:
- public Widget child { get; set; }
The child widget.
- public bool obey_child { get; set; }
Whether the `GtkAspectFrame` should use the aspect ratio of its child.
- public float ratio { get; set; }
The aspect ratio to be used by the `GtkAspectFrame`.
- public float xalign { get; set; }
The horizontal alignment of the child.
- public float yalign { get; set; }
The vertical alignment of the child.
Creation methods:
- public AspectFrame (float xalign, float yalign, float ratio, bool obey_child)
Create a new `GtkAspectFrame`.
Methods:
- public unowned Widget? get_child ()
Gets the child widget of this.
- public bool get_obey_child ()
Returns whether the child's size request should override the set aspect ratio of the `GtkAspectFrame`.
- public float get_ratio ()
Returns the desired aspect ratio of the child.
- public float get_xalign ()
Returns the horizontal alignment of the child within the allocation of the `GtkAspectFrame`.
- public float get_yalign ()
Returns the vertical alignment of the child within the allocation of the `GtkAspectFrame`.
- public void set_child (Widget? child)
Sets the child widget of this.
- public void set_obey_child (bool obey_child)
Sets whether the aspect ratio of the child's size request should override the set aspect ratio of the `GtkAspectFrame`.
- public void set_ratio (float ratio)
Sets the desired aspect ratio of the child.
- public void set_xalign (float xalign)
Sets the horizontal alignment of the child within the allocation of the `GtkAspectFrame`.
- public void set_yalign (float yalign)
Sets the vertical alignment of the child within the allocation of the `GtkAspectFrame`.
