All Implemented Interfaces:

Proxy

@Generated("io.github.jwharm.JavaGI")
public class RoundedRect
extends ProxyInstance

A rectangular region with rounded corners.

Application code should normalize rectangles using normalize(); this function will ensure that the bounds of the rectangle are normalized and ensure that the corner values are positive and the corners do not overlap.

All functions taking a GskRoundedRect as an argument will internally operate on a normalized copy; all functions returning a GskRoundedRect will always return a normalized one.

The algorithm used for normalizing corner sizes is described in the CSS specification.

Constructor Details

RoundedRect

public RoundedRect(MemorySegment address)

Create a RoundedRect proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

RoundedRect

public RoundedRect(Arena arena)

Allocate a new RoundedRect.

Parameters:

arena - to control the memory allocation scope

RoundedRect

public RoundedRect()

Allocate a new RoundedRect. The memory is allocated with Arena.ofAuto().

RoundedRect

public RoundedRect(Rect bounds,
 Size[] corner,
 Arena arena)

Allocate a new RoundedRect with the fields set to the provided values.

Parameters:

bounds - value for the field bounds

corner - value for the field corner

arena - to control the memory allocation scope

RoundedRect

public RoundedRect(Rect bounds,
 Size[] corner)

Allocate a new RoundedRect with the fields set to the provided values. The memory is allocated with Arena.ofAuto().

Parameters:

bounds - value for the field bounds

corner - value for the field corner

Method Details

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

readBounds

public @Nullable Rect readBounds()

Read the value of the field bounds.

Returns:

The value of the field bounds

writeBounds

public void writeBounds(@Nullable Rect bounds)

Write a value in the field bounds.

Parameters:

bounds - The new value for the field bounds

readCorner

public @Nullable Size @Nullable [] readCorner()

Read the value of the field corner.

Returns:

The value of the field corner

writeCorner

public void writeCorner(@Nullable Size @Nullable [] corner,
 Arena _arena)

Write a value in the field corner.

Parameters:

corner - The new value for the field corner

containsPoint

public boolean containsPoint(Point point)

Checks if the given point is inside the rounded rectangle.

Parameters:

point - the point to check

Returns:

true if the point is inside the rounded rectangle

containsRect

public boolean containsRect(Rect rect)

Checks if the given rectangle is contained inside the rounded rectangle.

Parameters:

rect - the rectangle to check

Returns:

true if the rect is fully contained inside the rounded rectangle

init

public RoundedRect init(Rect bounds,
 Size topLeft,
 Size topRight,
 Size bottomRight,
 Size bottomLeft)

Initializes a rounded rectangle with the given values.

This function will implicitly normalize the rounded rectangle before returning.

Parameters:

bounds - a graphene_rect_t describing the bounds

topLeft - the rounding radius of the top left corner

topRight - the rounding radius of the top right corner

bottomRight - the rounding radius of the bottom right corner

bottomLeft - the rounding radius of the bottom left corner

Returns:

the initialized rounded rectangle

initCopy

public RoundedRect initCopy(RoundedRect src)

Initializes a rounded rectangle with a copy.

This function will not normalize the rounded rectangle, so make sure the source is normalized.

Parameters:

src - another rounded rectangle

Returns:

the initialized rounded rectangle

initFromRect

public RoundedRect initFromRect(Rect bounds,
 float radius)

Initializes a rounded rectangle to the given bounds and sets the radius of all four corners equally.

Parameters:

bounds - a graphene_rect_t

radius - the border radius

Returns:

the initialized rounded rectangle

intersectsRect

public boolean intersectsRect(Rect rect)

Checks if part a rectangle is contained inside the rounded rectangle.

Parameters:

rect - the rectangle to check

Returns:

true if the rect intersects with the rounded rectangle

isRectilinear

public boolean isRectilinear()

Checks if all corners of a rounded rectangle are right angles and the rectangle covers all of its bounds.

This information can be used to decide if ClipNode(org.gnome.gsk.RenderNode, org.gnome.graphene.Rect) or RoundedClipNode(org.gnome.gsk.RenderNode, org.gnome.gsk.RoundedRect) should be called.

Returns:

true if the rounded rectangle is rectilinear

normalize

public RoundedRect normalize()

Normalizes a rounded rectangle.

This function will ensure that the bounds of the rounded rectangle are normalized and ensure that the corner values are positive and the corners do not overlap.

Returns:

the normalized rounded rectangle

offset

public RoundedRect offset(float dx,
 float dy)

Offsets the rounded rectangle's origin by dx and dy.

The size and corners of the rounded rectangle are unchanged.

Parameters:

dx - the horizontal offset

dy - the vertical offset

Returns:

the offset rounded rectangle

shrink

public RoundedRect shrink(float top,
 float right,
 float bottom,
 float left)

Shrinks (or grows) a rounded rectangle by moving the 4 sides according to the offsets given.

The corner radii will be changed in a way that tries to keep the center of the corner circle intact. This emulates CSS behavior.

This function also works for growing rounded rectangles if you pass negative values for the top, right, bottom or left.

Parameters:

top - how far to move the top side downwards

right - how far to move the right side to the left

bottom - how far to move the bottom side upwards

left - how far to move the left side to the right

Returns:

the resized rounded rectangle
