How can I do this? I'm trying to abuse

问题 When creating a context menu, is there a way to have header text included? For example, when a user clicks a button, I want a context menu to show with two options.

问题 I have an idea for a little C# program, where I want to be able to right click on a file in windows explorer and somehow 'tag' that file. Subsequent right clicks would show it's tagged state.

问题 I am looking for a way to add an option(s) to the right click context menu when editing text on a WinXP machine. I already do a lot of copy/pasting on it, so the clipboard is always changing, but there is one string I type repeatedly in almost every file I edit. I've already added some custom option to the context menu for .zip files to batch unzip them, but I'm not having any luck finding a way to add this. The machine is used for a single purpose and I try to keep it as stable as possible

问题 I am trying to implement a ContextMenu that appears when mouse is over a row. I was able to implement the context menu on selected row, but could not find an event for hover. Do I have to write my own implementation for data table, or is there a way to attach the context menu to a hover event? 回答1: Primefaces's contextMenu doesn't have option to get that, so you can use jquery to do that. If you want to show contextMenu, you have to change contextMenu's position to Mouse's position(page load

I'd really like to see any working example, dirty or not :) 回答1: Is it possible to add something to the list of
