class: GtkConstraintGuide

[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

GtkConstraintGuide (Handle = null)

Creates a new GtkConstraintGuide object.
- @p Handle is an optional native handle or wrapper whose handle to adopt; when the native constructor is called.
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 GObject.
- @r A GObject object.
asConstraintTarget ()

Wraps this handle as GtkConstraintTarget.
- @r A GtkConstraintTarget 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_max_size ()

Gets the maximum size of @guide.
- @p width is return location for the maximum width.
- @p height is return location for the maximum height.
- @r None.
get_min_size ()

Gets the minimum size of @guide.
- @p width is return location for the minimum width.
- @p height is return location for the minimum height.
- @r None.
get_name ()

Retrieves the name set using gtk_constraint_guide_set_name().
- @r the name of the guide.
get_nat_size ()

Gets the natural size of @guide.
- @p width is return location for the natural width.
- @p height is return location for the natural height.
- @r None.
get_strength ()

Retrieves the strength set using gtk_constraint_guide_set_strength().
- @r the strength of the constraint on the natural size.
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.
