八哥羽毛屏幕导航器

Question

I am wondering if there is a way to use this.owner.showScreen(screen_id) from within a class that doesn't inherit Screen?

I am building a footer class (similar to header but with custom controls) that I will include in multiple screens but the class needs to extend Starling Sprite. So basically it is an include file/class.

Thanks

Answer 1

As the getter method this.owner returns a reference to the screen navigator by which the classes that extend Screen are navigated, it's not possible to do so.

Why not simply create a class say, Footer, that extends feathers.controls.Header and have it have its y property as stage.height - this.height so that it'll be placed at bottom ? Or place the header on every class at bottom

// in initialize method of Screen classes
_header.y = stage.height - _header.height;

感觉空白是正确的，但是您不应该在初始化时这样做（舞台大小在某些移动设备上可能尚未准备好），我也不会使用舞台高度，而应该使用组件的实际高度。
