Generated metadata helpers for ConstraintGuide class surfaces.

Methods

• properties ()

  Returns property metadata for ConstraintGuide.

  • @r A list.

class: ConstraintGuide

[18:7] extends: object

An invisible layout element in a GtkConstraintLayout. The GtkConstraintLayout treats guides like widgets. They can be used as the source or target of a GtkConstraint. Guides have a minimum, maximum and natural size. Depending on the constraints that are applied, they can act like a guideline that widgets can be aligned to, or like flexible space. Unlike a GtkWidget, a GtkConstraintGuide will not be drawn.

Methods

• ConstraintGuide ()

  Creates a new GtkConstraintGuide object.

• 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.

• asObject ()

  Wraps this handle as Object.

  • @r A Object 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.

• setMaxheight (int Value)

  The maximum height of the guide.

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

• setMaxwidth (int Value)

  The maximum width of the guide.

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

• setMinheight (int Value)

  The minimum height of the guide.

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

• setMinwidth (int Value)

  The minimum width of the guide.

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

• setName (string Value)

  A name that identifies the GtkConstraintGuide, for debugging.

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

• setNatheight (int Value)

  The preferred, or natural, height of the guide.

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

• setNatwidth (int Value)

  The preferred, or natural, width of the guide.

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

• setStrength (string Value)

  The GtkConstraintStrength to be used for the constraint on the natural size of the guide.

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

• get_name ()

  Retrieves the name set using gtk_constraint_guide_set_name().

• get_strength ()

  Retrieves the strength set using gtk_constraint_guide_set_strength().

• set_max_size (int width, int height)

  Sets the maximum size of @guide. If @guide is attached to a GtkConstraintLayout, the constraints will be updated to reflect the new size.

  • @p width is the new maximum width, or -1 to not change it.
  • @p height is the new maximum height, or -1 to not change it.
  • @r None.

• set_min_size (int width, int height)

  Sets the minimum size of @guide. If @guide is attached to a GtkConstraintLayout, the constraints will be updated to reflect the new size.

  • @p width is the new minimum width, or -1 to not change it.
  • @p height is the new minimum height, or -1 to not change it.
  • @r None.

• set_name (string name)

  Sets a name for the given GtkConstraintGuide. The name is useful for debugging purposes.

  • @p name is a name for the @guide.
  • @r None.

• set_nat_size (int width, int height)

  Sets the natural size of @guide. If @guide is attached to a GtkConstraintLayout, the constraints will be updated to reflect the new size.

  • @p width is the new natural width, or -1 to not change it.
  • @p height is the new natural height, or -1 to not change it.
  • @r None.

• set_strength (string strength)

  Sets the strength of the constraint on the natural size of the given GtkConstraintGuide.

  • @p strength is the strength of the constraint.
  • @r None.
