本节依然在默认的 eui 项目中创建的教程代码。
在横向布局,以及下面将要讲的垂直布局,网格布局中,都会忽略在子项上的坐标设置,所有子项的位置将由布局类统一管理。
横向布局会自动将所有的子项横着排列,可以做以下的设置:
gap
属性,设置子项之间的间距horizontalAlign
属性,设置水平对齐方式verticalAlign
属性,设置垂直对齐方式padding
系列属性,设置容器内间距,相对于4个边分别可以使用paddingTop
,addingBottom
,addingLeft
,paddingRight
示例:
class hLayout extends egret.Sprite {
private myGroup:eui.Group;
public constructor() {
super();
this.myGroup = new eui.Group();
this.addChild( this.myGroup );
this.myGroup.layout = new eui.BasicLayout();
this.myGroup.width = 500;
this.myGroup.height = 300;
var outline:egret.Shape = new egret.Shape;
outline.graphics.lineStyle(3,0x00ff00);
outline.graphics.beginFill(0x000000,0);
outline.graphics.drawRect(0,0,500,300);
outline.graphics.endFill();
this.myGroup.addChild(outline);
var btn1:eui.Button = new eui.Button();
btn1.label = "button A";
var btn2:eui.Button = new eui.Button();
btn2.label = "button B";
var btn3:eui.Button = new eui.Button();
btn3.label = "button C";
this.myGroup.addChild( btn1 );
this.myGroup.addChild( btn2 );
this.myGroup.addChild( btn3 );
var hLayout:eui.HorizontalLayout = new eui.HorizontalLayout();
hLayout.gap = 10;
hLayout.paddingTop = 30;
hLayout.horizontalAlign = egret.HorizontalAlign.CENTER;
this.myGroup.layout = hLayout; /// 水平布局
}
}
效果如图:
