FFloat class

FFloat 能够在屏幕的任意位置浮出一个组件。甚至可以基于 anchor 锚点组件来动态的确定漂浮组件的位置。 FFloat 同时提供了绝妙的配置选项。圆角、描边、背景、偏移、装饰三角。 FFloat 设置了 FFloatController 控制器，可以方便的随时对漂浮组件进行控制。

FFloat can float a component anywhere on the screen. You can even dynamically determine the position of the floating component based on the anchor anchor component. FFloat also provides wonderful configuration options. Fillet, stroke, background, offset, decorative triangle. FFloat The FFloatController controller is set, which can easily control the floating component at any time.
