方法详细资料

configure

default void configure(Theme theme)

Called by Ui.render before any widget drawing; custom backends may override.

corners

default void corners(CornerRadii profile)

Scoped profile for the current widget. Null restores its normal radius argument.

clip

void clip(Rect r)

pushShapeClip

default void pushShapeClip(Rect bounds,
 float radius,
 CornerRadii profile)

Push an intersecting rounded content clip. Coordinates are logical/absolute. A null profile follows the active theme, with the supplied radius. Max native depth: 32. Custom painters that do not override these methods retain the existing rectangular clips.

popShapeClip

default void popShapeClip()

Pop only the last shaped content clip; does not change the rectangular scissor.

glass

void glass(float x,
 float y,
 float w,
 float h,
 float radius,
 Theme t,
 float blur)

fill

void fill(float x,
 float y,
 float w,
 float h,
 float radius,
 int color)

stroke

void stroke(float x,
 float y,
 float w,
 float h,
 float radius,
 float thickness,
 int color)

line

void line(float x,
 float y,
 float x2,
 float y2,
 float thickness,
 int color)

ring

void ring(float x,
 float y,
 float size,
 float thickness,
 float progress,
 float start,
 int color)

colorPlane

void colorPlane(float x,
 float y,
 float w,
 float h,
 float hue)

colorPlaneAlpha

default void colorPlaneAlpha(float x,
 float y,
 float w,
 float h,
 float hue,
 float alpha)

text

void text(String text,
 float x,
 float y,
 float size,
 int color)

textWidth

float textWidth(String text,
 float size)

textScaled

default void textScaled(String text,
 float x,
 float y,
 float size,
 int color,
 float scale)

Affine text scaling without regenerating rasterized glyphs on every animated frame.

textWeight

default void textWeight(String text,
 float x,
 float y,
 float size,
 int color,
 int weight)

textWeightScaled

default void textWeightScaled(String text,
 float x,
 float y,
 float size,
 int color,
 int weight,
 float scale)

textWidth

default float textWidth(String text,
 float size,
 int weight)

backdrop

void backdrop()

Freeze the already drawn UI into a new backdrop for overlays.
