SKCanvasView.PaintSurface 事件

  • 参考

定义

命名空间:
SkiaSharp.Views.Forms
程序集:
SkiaSharp.Views.Forms.dll

需要重绘画布时发生。

public event EventHandler<SkiaSharp.Views.Forms.SKPaintSurfaceEventArgs> PaintSurface;
public event EventHandler<SkiaSharp.Views.Forms.SKPaintSurfaceEventArgs>? PaintSurface;

事件类型

EventHandler<SKPaintSurfaceEventArgs>

示例

myView.PaintSurface += (sender, e) => {
    var surface = e.Surface;
    var surfaceWidth = e.Info.Width;
    var surfaceHeight = e.Info.Height;

    var canvas = surface.Canvas;

    // draw on the canvas

    canvas.Flush ();
};

注解

在此图面上绘制有两种方法：重写 OnPaintSurface(SKPaintSurfaceEventArgs) 方法，或将处理程序附加到 PaintSurface 事件。
