Flex4 使用 ContextMenu() 右键单击 Spark 列表
我想向许多火花列表控件添加自定义右键单击。 我已尝试以下作为项目渲染器。 (根据 Flex 4 烹饪书)。
完整的渲染代码在这里 http://pastebin.com/Kx8tJ1cY
当我右键单击 Spark 列表时,我只需得到Adobe 默认上下文菜单。 这与我添加任何代码之前的默认行为相同。
谁能告诉我如何在 Flex 4 中添加右键单击列表项目。
请,谢谢。
I would like to add custom right clicks to a number of spark list controls.
I have tried the following as an item renderer. (as per the flex 4 cook book).
Full Render code here http://pastebin.com/Kx8tJ1cY
When I right click on the Spark List I simply get the Adobe Default Context menu.
This is the same default behaviour I had before I added any code to this.
Could anyone tell me how to add right clicks to List Items in Flex 4.
Please and Thank you.

我找到了问题/解决方案。如果有 Vbox 或选项卡导航器,则无法使用上下文菜单。这很疯狂,因为这意味着我无法正确进行相对布局或体面的可变宽度设计。
引用自:http://help.adobe。 com/en_US/FlashPlatform/reference/actionscript/3/flash/ui/ContextMenu.html
例如,如果 DataGrid 控件是 TabNavigator 或 VBox 容器的子级,则 DataGrid 控件不能有自己的上下文菜单。
I found the problem/solution. You cant use context menus if there are Vboxes or Tab Navigators. Which is insane because it means I cant do relative layout properly or decent variable width design.
Quoted from: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/ui/ContextMenu.html
For example, if a DataGrid control is a child of a TabNavigator or VBox container, the DataGrid control cannot have its own context menu.
Christopher Huyler 发布了一些内容类似(源代码可在此处获取)。摘自文章:
首先从 Google 代码存储库获取 Javascript 代码。
第 1 步 – 设置自定义上下文菜单代码
在 Flex Builder 中创建一个新的 Flex 项目。将 rightclick.js 和 swfobject.js 复制到项目的 html-template 文件夹中。从这里开始,我必须进行一些更改...
进行这些更改后,我验证了我的应用程序中没有出现右键单击上下文菜单。
第 2 步 – 侦听 rightClick 事件
接下来,我向应用程序的主 mxml 文件中添加了几行,以侦听当我右键单击应用程序时将调度的ExternalInterface 事件。
第 3 步 – 将事件分派到正确的对象
将事件发送到主应用程序很容易,但我们实际上希望在右键单击事件发生时通知适当的子对象。由于我没有在应用程序中使用任何双击事件,因此我决定将每个右键单击事件视为双击事件。没有两键鼠标的用户(也称为 Mac 用户)只需双击即可获得相同的菜单,而拥有两键鼠标的用户只需右键单击即可。以下是我如何确保将事件分派到适当的对象。
我希望这有帮助!
Christopher Huyler posted something similar (source code available here). From the article:
Start out by grabbing the Javascript code from Google's code repository.
Step 1 – Setup custom context menu code
Create a new Flex project in Flex Builder. Copy rightclick.js and swfobject.js into the html-template folder of your project. From here, I had to make several changes…
After making these changes, I verified that no right-click context menu appears in my application.
Step 2 – Listen for the rightClick event
Next I added a few lines to the main mxml file of my application to listen for the ExternalInterface event that will be dispatched when I right-click my appliction.
Step 3 – Dispatch an event to the correct object
Getting the event to the main application is easy, but we actually want the appropriate child object to be notified when the right-click event occurs. Since I am not using any double-click events in my application I decided I would treat every right-click event like a double-click event. Users without a two button mouse (aka Mac users) can simply double-click to get the same menu while users with a two button mouse just have to right-click. Here is how I make sure the event is dispatched to the appropriate object.
I hope this helps!
