构造器详细资料

NativePainter

public NativePainter(NativeBackend backend)

方法详细资料

begin

public void begin(float width,
 float height,
 int pixelWidth,
 int pixelHeight)

Supply physical dimensions before text layout to avoid a first-frame DPI mismatch.

configure

public void configure(Theme theme)

从接口复制的说明: Painter

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

指定者:

configure 在接口中 Painter

corners

public void corners(CornerRadii profile)

从接口复制的说明: Painter

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

指定者:

corners 在接口中 Painter

begin

public void begin(float width,
 float height)

flush

public void flush(int framebuffer,
 int colorAttachment,
 int pw,
 int ph,
 float sigma,
 float mx,
 float my)

flushWindow

public void flushWindow(int width,
 int height,
 float sigma,
 float mx,
 float my)

commandCount

public int commandCount()

glyphCount

public int glyphCount()

sdfGlyphCount

public int sdfGlyphCount()

fontFamily

public String fontFamily()

clip

public void clip(Rect r)

指定者:

clip 在接口中 Painter

pushShapeClip

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

从接口复制的说明: Painter

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.

指定者:

pushShapeClip 在接口中 Painter
