Constructor Details

RadialGradientNode

public RadialGradientNode(MemorySegment address)

Create a RadialGradientNode proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

RadialGradientNode

public RadialGradientNode(Rect bounds,
 Point center,
 float hradius,
 float vradius,
 float start,
 float end,
 @Nullable ColorStop @Nullable [] colorStops)

Creates a GskRenderNode that draws a radial gradient.

The radial gradient starts around center. The size of the gradient is dictated by hradius in horizontal orientation and by vradius in vertical orientation.

Parameters:

bounds - the bounds of the node

center - the center of the gradient

hradius - the horizontal radius

vradius - the vertical radius

start - a percentage >= 0 that defines the start of the gradient around center

end - a percentage >= 0 that defines the end of the gradient around center

colorStops - a pointer to an array of GskColorStop defining the gradient. The offsets of all color stops must be increasing. The first stop's offset must be >= 0 and the last stop's offset must be <= 1.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the RadialGradientNode class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected RadialGradientNode 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 RenderNode

getCenter

public Point getCenter()

Retrieves the center pointer for the gradient.

Returns:

the center point for the gradient

getColorStops

public ColorStop[] getColorStops()

Retrieves the color stops in the gradient.

Returns:

the color stops in the gradient

getEnd

public float getEnd()

Retrieves the end value for the gradient.

Returns:

the end value for the gradient

getHradius

public float getHradius()

Retrieves the horizontal radius for the gradient.

Returns:

the horizontal radius for the gradient

getNColorStops

public long getNColorStops()

Retrieves the number of color stops in the gradient.

Returns:

the number of color stops

getStart

public float getStart()

Retrieves the start value for the gradient.

Returns:

the start value for the gradient

getVradius

public float getVradius()

Retrieves the vertical radius for the gradient.

Returns:

the vertical radius for the gradient
