阅读更多关于 How do you show the Windows Explorer context menu from a C# application?

I have a file listing in my application and I would like to allow people to right-click on an item and show the Windows Explorer context menu. I'm assuming I would need to use the IContextMenu interface, but I'm not really sure where to start.

Angular 2 right click events?

阅读更多关于 Angular 2 right click events?

问题 I am building an interactive web application with Angular2 and I am looking for a way to capture right clicks on an angular component. I also need to prevent the browser context menu appearing on a right click so I can display my own custom context menu. I know that in angular 1, you had to create a custom directive to capture a right click event. Is this still the case in Angular 2, or is it built in/is there an easier way of doing it? I've had a look through some previous SO questions but

Configuring jstree right-click contextmenu for different node types

阅读更多关于 Configuring jstree right-click contextmenu for different node types

I've seen an example somewhere online showing how to customise the appearance of jstree's right-click context menu (using contextmenu plugin). For example, allow my users to delete "documents" but not "folders" (by hiding the "delete" option from the context menu for folders). Now I can't find that example. Can anyone point me in the right direction? The official documentation didn't really help. Edit: Since I want the default context menu with only one or two minor changes, I'd prefer to not recreate the whole menu (though of course I will if it's the only way). What I'd like to do is

Show context menu when link is long pressed in TextView

阅读更多关于 Show context menu when link is long pressed in TextView

问题 I have a TextView with its MovementMethod set to LinkMovementMethod . Text added to the TextView is a combination of normal text and URLs. For URLs, I would like to offer a context menu when the URL is long pressed for doing things such as copying the address. I've had a look at the source for LinkMovementMethod but it doesn't seem to have any long pressed related code I could override. Any ideas on how to go around achieving this? 回答1: You can simply use registerForContextMenu eg: TextView

How to disable the default context menu on a text field

阅读更多关于 How to disable the default context menu on a text field

问题 By default the JavaFX TextField has a built in ContextMenu with 'undo', 'copy', 'cut' etc. options. The ComboBox also has the same ContextMenu when it is set as editable (the ComboBox is actually part of the editor which is a TextField ). I want to replace this ContextMenu with a custom one but I'm having a problem with disabling the default one. I have tried consuming the ContextMenu and mouse click events but ComboBox and ComboBox.getEditor() both have a null ContextMenu . Am I missing

How do I trigger the browser context menu on an element. (As if the user right-clicked)

阅读更多关于 How do I trigger the browser context menu on an element. (As if the user right-clicked)

I have the need to trigger the opening of the browser (IE, Firefox, Safari, etc) context-menu via javascript. The problem I am trying to solve, is when an overlaid element is right-clicked, the element below it shows its context menu. So if the top element is a label, when you right click, I need to show the context menu for the input element below. I know how to keep the label's context menu from showing, but I don't know how to open a context menu arbitrarily. Any help is appreciated! Sorry to be the bearer of unfortunate news, but this is impossible to do with Javascript. I don't want to
