[]更新到1.7.6beta之后，HBox有bug

Laya.init(1200, 400);

Laya.loader.load([{ url: "res/atlas/comp.json", type: Loader.ATLAS }], Handler.create(this, this.onLoaded));



function onLoaded(): void {

	var hbox: laya.ui.HBox = new laya.ui.HBox();

	for (var i: number = 0; i < 10; i++) {

		var skin: string;

		switch (i) {

			case 0:

				skin = "comp/bg.png";

				break;

			case 1:

				skin = "comp/blank.png";

				break;

			case 2:

				skin = "comp/btn_close.png";

				break;

			case 3:

				skin = "comp/button.png";

				break;

			case 4:

				skin = "comp/checkbox.png";

				break;

			case 5:

				skin = "comp/clip_selectBox.png";

				break;

			case 6:

				skin = "comp/clip_tree_arrow.png";

				break;

			case 7:

				skin = "comp/clip_tree_folder.png";

				break;

			case 8:

				skin = "comp/combobox.png";

				break;

			case 9:

				skin = "comp/hscroll$down.png";

				break;

		}

		var s:laya.display.Sprite = new laya.display.Sprite();

		var img: laya.ui.Image = new laya.ui.Image(skin);

		s.width = img.width;

		s.height = img.height;

		s.addChild(img);

		hbox.addChild(s);

	}

	Laya.stage.addChild(hbox);
