Generated metadata helpers for AspectFrame class surfaces.

Methods

• properties ()

  Returns property metadata for AspectFrame.

  • @r A list.

class: AspectFrame

[17:7] extends: object

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 aspectframe. # Accessibility Until GTK 4.10, GtkAspectFrame used the [enum@Gtk.AccessibleRole.group] role. Starting from GTK 4.12, GtkAspectFrame uses the [enum@Gtk.AccessibleRole.generic] role.

Methods

• AspectFrame (xalign = null, yalign = null, ratio = null, obey_child = null)

  Create a new GtkAspectFrame.

  • @p xalign is Horizontal alignment of the child within the parent. Ranges from 0.0 (left aligned) to 1.0 (right aligned).
  • @p yalign is Vertical alignment of the child within the parent. Ranges from 0.0 (top aligned) to 1.0 (bottom aligned).
  • @p ratio is The desired aspect ratio..
  • @p obey_child is If %TRUE, @ratio is ignored, and the aspect ratio is taken from the requistion of the child..

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asWidget ()

  Wraps this handle as Widget.

  • @r A Widget object.

• asAccessible ()

  Wraps this handle as Accessible.

  • @r A Accessible object.

• asBuildable ()

  Wraps this handle as Buildable.

  • @r A Buildable object.

• asConstraintTarget ()

  Wraps this handle as ConstraintTarget.

  • @r A ConstraintTarget object.

• getProperty (string Name)

  Reads one generated property by name.

• setProperty (string Name, Value)

  Writes one generated property by name.

• setChild (object Value)

  The child widget.

  • @p Value is the new property value.
  • @r None.

• setObeychild (bool Value)

  Whether the GtkAspectFrame should use the aspect ratio of its child.

  • @p Value is the new property value.
  • @r None.

• setRatio (double Value)

  The aspect ratio to be used by the GtkAspectFrame. This property is only used if [property@Gtk.AspectFrame:obey-child] is set to %FALSE.

  • @p Value is the new property value.
  • @r None.

• setXalign (double Value)

  The horizontal alignment of the child.

  • @p Value is the new property value.
  • @r None.

• setYalign (double Value)

  The vertical alignment of the child.

  • @p Value is the new property value.
  • @r None.

• get_child ()

  Gets the child widget of @self.

• get_obey_child ()

  Returns whether the child's size request should override the set aspect ratio of the GtkAspectFrame.

• get_ratio ()

  Returns the desired aspect ratio of the child.

• get_xalign ()

  Returns the horizontal alignment of the child within the allocation of the GtkAspectFrame.

• get_yalign ()

  Returns the vertical alignment of the child within the allocation of the GtkAspectFrame.

• set_child (object child)

  Sets the child widget of @self.

  • @p child is the child widget.
  • @r None.

• 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.

  • @p obey_child is If %TRUE, @ratio is ignored, and the aspect ratio is taken from the requisition of the child..
  • @r None.

• set_ratio (double ratio)

  Sets the desired aspect ratio of the child.

  • @p ratio is aspect ratio of the child.
  • @r None.

• set_xalign (double xalign)

  Sets the horizontal alignment of the child within the allocation of the GtkAspectFrame.

  • @p xalign is horizontal alignment, from 0.0 (left aligned) to 1.0 (right aligned).
  • @r None.

• set_yalign (double yalign)

  Sets the vertical alignment of the child within the allocation of the GtkAspectFrame.

  • @p yalign is horizontal alignment, from 0.0 (top aligned) to 1.0 (bottom aligned).
  • @r None.
