FLEX 屏閉系統右鍵菜單，及在列表控件DataGrid/Tree/List上點右鍵時自動選擇當前行

第一步：到http://rightclickmanager.googlecode.com/下載rightclickmanager-source-lib-0.1.rar並引入自己的FLEX工程，這是實現右鍵點擊事件，及完全屏閉系統右鍵菜單的關鍵！

第二步：打開: <主程序名>.template.html 文件，修改爲：

<!-- AC_FL_RunContent( "src", "${swf}", "id", "${application}", "name", "${application}", "width", "${width}", "height", "${height}", "align", "middle", "menu", "false", "wmode", "opaque", //注意:這裏是右鍵屏蔽的關鍵 "quality", "high", "bgcolor", "${bgcolor}", "allowScriptAccess", "always", "allowNetworking", "all", "allowFullScreen", "true", //是否可全屏的參數 "type", "application/x-shockwave-flash", "pluginspage", "http://www.adobe.com/go/getflashplayer" ); //-->

第三步：在主程序文件.as中引入：

    import com.siloon.plugin.rightClick.RightClickManager;

 

並加如下代碼：

[Event(name="rightClick",type="fla sh.events.ContextMenuEvent")] public class index { protected var rightClickRegisted:Boolean = false; public function index() { super(); if (!rightClickRegisted) { RightClickManager.regist(); rightClickRegisted = true; } try { name = NameUtil.createUniqueName(this); } catch (e:Error) { } return; } public override function toString() : String { return NameUtil.displayObjectToString(this); }

 

第四步：在要彈出右鍵的控件的初始化代碼中加入：

 

NavTabTree.addEventListener(RightClickManager.RIGHT_CLICK,rightClickHandler);

 

再加以下函數來處理：

 

/** * 在控制上單擊右鍵菜單事件的處理函數 * @param event 右鍵事件 * */ protected function rightClickHandler(event:ContextMenuEvent):void { onRightClicked(event); removeMenu(); menu = new Menu(); menu = Menu.createMenu(this, createMenuItems(), false); menu.labelField="label" menu.variableRowHeight = true; //menu.addEventListener(MenuEvent.ITEM_CLICK, menuItemClickHandler); var point:Point = new Point(mouseX,mouseY); point = localToGlobal(point); menu.show(point.x,point.y); } /** * 如果顯示過Menu，則先釋放資源 * */ private function removeMenu():void { if(menu!=null) { menu.hide(); //menu.removeEventListener(MenuEvent.ITEM_CLICK,menuItemClickHandler); menu=null; } } /** * 創建右鍵菜單選項 * @return 返回選項組成的Array * */ private function createMenuItems():Array { var menuItems:Array = new Array(); var menuItem:Object; menuItem = new Object; menuItem.label = '清空畫布'; menuItem.action = 'clearAll'; menuItems.push(menuItem); menuItem = new Object; menuItem.label = '選擇背景'; menuItem.action = 'selectBackImage'; menuItems.push(menuItem); return menuItems; } /** * 當右鍵單擊Tree的Item時，自動選擇鼠標所在的當前項 * @param e 自定義右鍵菜單事件 * */ private function onRightClicked(e:ContextMenuEvent):void { var rightClickItemRender:IListItemRenderer; var rightClickIndex:int; if(e.mouseTarget is IListItemRenderer) { rightClickItemRender = IListItemRenderer(e.mouseTarget); }else if(e.mouseTarget.parent is IListItemRenderer) { rightClickItemRender = IListItemRenderer(e.mouseTarget.parent); } if(rightClickItemRender != null) { rightClickIndex = NavTabTree.itemRendererToIndex(rightClickItemRender); if(NavTabTree.selectedIndex != rightClickIndex) { NavTabTree.selectedIndex = rightClickIndex; } } }

 

第五步：

 

修改RightClickManager.as文件的

 

static private var rightClickTarget:*;

 

再修改兩個該文件的兩個函數：

 

static private function mouseOverHandler(event:MouseEvent) : void { rightClickTarget = InteractiveObject(event.target); return; } static private function dispatchRightClickEvent() : void { var event:ContextMenuEvent; if (rightClickTarget != null) { event = new ContextMenuEvent(RIGHT_CLICK, true, false, rightClickTarget as InteractiveObject, rightClickTarget as InteractiveObject); rightClickTarget.dispatchEvent(event); }// end if return; }

 

        到這裏，功能就完成了，本人修改了RightClickManager的事件從MouseEvent改爲ContextMenuEvent是爲了能在列表控件DataGrid/Tree/List上點右鍵時自動選擇當前行，使用了ContextMenuEvent事件中的event.mouseTarget和列表控件的IListItemRenderer接口！

 

        本功能也有副作用，系統右鍵菜單失效，那文本的右鍵複製粘貼也就失效了，有大量用到TEXTINPUT的就要小心使用了~！
