@Generated("io.github.jwharm.JavaGI")
public class ConstraintGuide
extends GObject
implements ConstraintTarget

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.

Constructor Details

ConstraintGuide

public ConstraintGuide(MemorySegment address)

Create a ConstraintGuide proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ConstraintGuide

public ConstraintGuide()

Creates a new ConstraintGuide.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ConstraintGuide class

Returns:

the GType

asParent

protected ConstraintGuide asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class GObject

getMaxSize

public void getMaxSize(@Nullable Out<Integer> width,
 @Nullable Out<Integer> height)

Gets the maximum size of guide.

Parameters:

width - return location for the maximum width

height - return location for the maximum height

getMinSize

public void getMinSize(@Nullable Out<Integer> width,
 @Nullable Out<Integer> height)

Gets the minimum size of guide.

Parameters:

width - return location for the minimum width

height - return location for the minimum height

getName

public @Nullable String getName()

Retrieves the name set using gtk_constraint_guide_set_name().

Returns:

the name of the guide

getNatSize

public void getNatSize(@Nullable Out<Integer> width,
 @Nullable Out<Integer> height)

Gets the natural size of guide.

Parameters:

width - return location for the natural width

height - return location for the natural height

getStrength

public ConstraintStrength getStrength()

Retrieves the strength set using gtk_constraint_guide_set_strength().

Returns:

the strength of the constraint on the natural size

setMaxSize

public void setMaxSize(int width,
 int height)

Sets the maximum size of guide.

If this ConstraintGuide is attached to a GtkConstraintLayout, the constraints will be updated to reflect the new size.

Parameters:

width - the new maximum width, or -1 to not change it

height - the new maximum height, or -1 to not change it

setMinSize

public void setMinSize(int width,
 int height)

Sets the minimum size of guide.

If this ConstraintGuide is attached to a GtkConstraintLayout, the constraints will be updated to reflect the new size.

Parameters:

width - the new minimum width, or -1 to not change it

height - the new minimum height, or -1 to not change it

setName

public void setName(@Nullable String name)

Sets a name for the given GtkConstraintGuide.

The name is useful for debugging purposes.

Parameters:

name - a name for the this ConstraintGuide

setNatSize

public void setNatSize(int width,
 int height)

Sets the natural size of guide.

If this ConstraintGuide is attached to a GtkConstraintLayout, the constraints will be updated to reflect the new size.

Parameters:

width - the new natural width, or -1 to not change it

height - the new natural height, or -1 to not change it

setStrength

public void setStrength(ConstraintStrength strength)

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

Parameters:

strength - the strength of the constraint

builder

public static ConstraintGuide.Builder<? extends ConstraintGuide.Builder> builder()

A ConstraintGuide.Builder object constructs a ConstraintGuide with the specified properties. Use the various set...() methods to set properties, and finish construction with ConstraintGuide.Builder.build().

Returns:

the builder object
