flex设计器功能拆分之一(调整组件大小位置)

只要是设计器就逃不脱对组件的动态调整。比如大小，位置是最常见的。

在flashBuilder中可以看到下面效果图：


在此简单实现，更多细节不予考虑，有点伤到我的神经了，总体设计思路图：



 由resizeUI完成核心功能。

ResizeContainer容器类：

package org.forever.view
{
	import flash.events.MouseEvent;
	
	import mx.collections.ArrayList;
	import mx.core.IUIComponent;
	
	import spark.components.SkinnableContainer;
	
	/**容器类*/
	public class ResizeContainer
	{
		
		
		private var _app_container:SkinnableContainer;
		private var _current_resizeUI:ResizeUI;
		private var _resizeUIList:ArrayList;

		public function get mouseMoveCallFun():Function
		{
			return _mouseMoveCallFun;
		}

		public function set mouseMoveCallFun(value:Function):void
		{
			_mouseMoveCallFun = value;
		}

		private var _mouseMoveCallFun:Function;
		
		public function ResizeContainer(app_container:SkinnableContainer){
			_app_container = app_container;
			initContainer();
			
			_resizeUIList = new ArrayList();
		}
		
		public function get current_resizeUI():ResizeUI
		{
			return _current_resizeUI;
		}

		public function set current_resizeUI(value:ResizeUI):void
		{
			if(null!=_current_resizeUI){
				_current_resizeUI.hideResizeUI();	
			}
			_current_resizeUI = value;
			
		}

		public function register(uicomp:IUIComponent):void{	
			var _resizeUI:ResizeUI = new ResizeUI(uicomp,_app_container);
			_resizeUI.resizeContainer = this;
			_resizeUIList.addItem(_resizeUI);
		}
		
		
		public function initContainer():void{
			_app_container.addEventListener(MouseEvent.MOUSE_DOWN,appContainerMouseDownHandler);
			_app_container.addEventListener(MouseEvent.MOUSE_MOVE,appContainerMouseMoveHandler);
			_app_container.addEventListener(MouseEvent.MOUSE_UP,appContainerMouseUpHandler);
		}
		
		public function appContainerMouseDownHandler(event:MouseEvent):void{
			event.stopImmediatePropagation();
			if(null!=_current_resizeUI){
				_current_resizeUI.hideResizeUI();	
			}
		}
		
		public function appContainerMouseMoveHandler(event:MouseEvent):void{
			if(null != _mouseMoveCallFun){
				_mouseMoveCallFun(event);
			}
		}
		
		public function appContainerMouseUpHandler(event:MouseEvent):void{
			if(null != _mouseMoveCallFun){
				_mouseMoveCallFun = null;
				if(null!=_current_resizeUI)_current_resizeUI.updateUIComp();
			}
		}
		
		
		
		
	}
}
