问题 I'm playing with a grails app that has a contextmenu (on right-click). The context menu is built using Chris Domigan's jquery contextmenu plugin. While the contextmenus do actually work, I want to have automated tests, and I can't work out how to do it. I've tried Selenium 2.05a (ie. Webdriver), but there's no rightClick method. I notice that HtmlUnit has a rightclick method, but I don't seem to be able to detect any difference in the DOM between before the click and after it. 回答1: Currently

问题 Context menu is truncated in different .NET Framework. See images inside ZIP file (there are two screenshots, one from XP and other from Win7). I created a simple Visual Studio 2010 solution which repro my issue. ( http://www.mediafire.com/download.php?doq7gsh75qgvzwq ). On XP it seems to work fine, but not on Windows 7. The issue can be reproduced on Windows 7 if target .NET Framework is 3.5 (including SP1) (please see the image from zip). If I change the target framework to 4.0 it works

问题 I am learning javafx.scene.control.ContextMenu, and right now I am facing a problem: how do I get the clicked Object from EventHandler? both event.source() and event.target() return the MenuItem. let me explain with an example: what should I write inside the function handle? TextField text = new TextField(); Label label1 = new Label("hello"); Label label2 = new Label("world"); Label label3 = new Label("java"); ContextMenu menu = new ContextMenu(); MenuItem item = new MenuItem("copy to text

问题 I have a context menu that gets menu items through databinding (I'm using the MVVM pattern): <ContextMenu ItemsSource="{Binding Path=ContextMenuItems}" /> This works fine. However, in the cases when there are no menu items to show, I don't want the context menu to show up at all. Is there a way to accomplish this? Some kind of XAML trigger maybe? I've tried catching the Opened event och closing the context menu when there are no children. This works but the context menu still flashes by...

问题 I think that this is not possible but I think it is better to ask someone who knows the answer for sure. Is it possible to create an android application that affect the context menu in all applications so that when the user long press an edit text view, not only the paste option will be visible but also my customized paste function? What I want to do is to make it easy for the user to import texts from my application without leaving the application they are working in. One thing I have

问题 Is there a standard way to add a footer to a context menu , in which I can add a checkbox to make the selected option the default one? Similar to the context menu that comes up when choosing the default home screen for example. From the Api docs for ContextMenu I see that you can set a header view, but not a footer view. Also the setCheckable / setGroupCheckable methods don't seem to help much here. Does this need to be done via a custom (alert) dialog? I would be wondering if nobody has yet

问题 I'm going to start of by noting that I have next to no python experience. alt text http://www.aquate.us/u/9986423875612301299.jpg As you may know, by simply dropping a shortcut in the Send To folder on your Windows PC, you can allow a program to take a file as an argument. How would I write a python program that takes this file as an argument? And, as a bonus if anyone gets a chance -- How would I integrate that with a urllib2 to POST the file to a PHP script on my server? Thanks in advance.

问题 I'm trying to add a context menu to a column in the WPF datagrid and don't quite see how this is possible. I know how to add one to the datagrid, but I would like to have different menu items based on the column as well have the menu click event be aware of column or better yet the cell that the context menu was chosen for. My ultimate goal is to create a context menu that has a "Clear" menu item which will be used to null out the data in that column. I don't want an empty string or false in
