[kittaakos]

Closes #7767.

Signed-off-by: Akos Kitta kittaakos@typefox.io

What it does

Enables the context menu in input and textArea elements. For electron only.

How to test

• You can see the context menu for input and textArea,
• You can Select All, Cut, Copy, and Paste.

Review checklist

• as an author, I have thoroughly tested my changes and carefully followed the review guidelines

Reminder for reviewers

• as a reviewer, I agree to behave in accordance with the review guidelines

Please keep in mind, that the input value will be automatically selected, so when you paste, the original value will be replaced. See here: microsoft/vscode#99126 (comment), I was confused by the SCM "input" for instance, but that's a monaco editor eventually.

The changes work really well! 👍 I verified both inputs and textarea

• the search-in-workspace input
• the scm textarea

I think we can also use this as an example to create a similar context-menu for the browser target.

for the browser target.

The browser supports them natively:

for the browser target.

Yes, but I was thinking we should do it for the browser target so that:

• we have consistent looking menus in the browser as well
• it will still work once we decide to disable the browser's context-menu: Prevent default browser context-menu #6430

Nice, any electron screenshots?

[kittaakos]

Sure.

Yes, but I was thinking we should do it for the browser target so that:

I do not like the idea; I am pretty happy with the native one. It does all I need, in fact, I would like to use the native one in electron too, but it's not possible as far as I know. The only reason I did this change is to be able to paste a password into the input from a password manager in electron env.

Of course, if you think this would add value to Theia, feel free to open a separate issue for discussion. If it's just something we could do, but there is no good reason doing it, let's just not do it.

I think in general we should use native implementations wherever possible. It feels more natural to the user.
