Linux: support copy&paste functionality (XF86Copy, XF86Paste, XF86Cut, XF86Undo, XF86Redo, etc...)

mikkovedru commented 5 years ago

I am a keyboard power user and in that I am greatly helped by the DreymaR's Extend. The idea is simple: use the separate Extend key (by default mapped to CapsLock key), which opens up a bunch of functionality without the need to move my fingers too much. In practice it's even more amazing and useful than one could imagine.

The problem is that the basic functionality of Cut/Copy/Paste/Undo/Redo doesn't work in Telegram. It works in OS, it works in Firefox, it works in LibreOffice and everywhere else, but sadly it doesn't work in Telegram Desktop.

Steps to reproduce

Install Extend.
See for yourself that although other buttons work, the Cut/Copy/Paste/Undo functionality doesn't work in Telegram (for example in Firefox/LibreOffice everything works fine).

Expected behaviour

XFree86 has a bunch of XF86 keyboard symbols and the vast majority of them are not relevant to Telegram. But there is a number of them that are highly relevant. At the very least:

XF86Copy,
XF86Paste,
XF86Cut,
XF86Undo,
XF86Redo

It would be very nice to fix Telegram Desktop to support them.

If one has time, one could additionally look at implementing other shortcuts such as: (- XF86Back?) (- XF86Clear?) (- XF86Forward?) (- XF86Go?) (- XF86History?) (- XF86Search?)

Configuration

Operating system: Linux Mint 19.1 Cinnamon (4.0.9).

Version of Telegram Desktop: 1.6.1.

Used theme: Classic.

Are you sure about other Qt5 based applications works with it?

mikkovedru commented 5 years ago

@vitlav . I don't know which application works with what. If you could you give me several examples of the Qt5 based applications then I could test them and report the results here.

VLC, qBittorrent

mikkovedru commented 4 years ago

It works in both VLC and qBittorrent.

Linux Mint 19.3 Cinnamon (4.4.8).

How can I emulate these keys to test myself?

mikkovedru commented 4 years ago

I don't know if it is the easiest way, but you can:

install the DreymaR's Extend: https://forum.colemak.com/topic/1438-dreymars-big-bag-of-keyboard-tricks-linuxxkb-files-included/ https://github.com/DreymaR/BigBagKbdTrixXKB
Enable it in settings:
Use CAPS LOCK + (X, C, V) to test the functionality.

1. install the DreymaR's Extend:

How can I test without that?

mikkovedru commented 4 years ago

I don't know what kind of signals some specific keyboards send. Some of them might be of the needed format and you can get the keyboard to test.
Or you can make your own little application that would send necessary keys.
Maybe you can find some program that would allow you to easily change the button combinations? Maybe something like AutoKey ( not to be confused with the similar Windows' program AutoHotKey )?
Or you could edit your keyboard files ( /usr/share/X11/xkb/ ). You can see the examples in the Extend files (https://github.com/DreymaR/BigBagKbdTrixXKB/tree/master/xkb-data_mod/xkb) like here ( https://github.com/DreymaR/BigBagKbdTrixXKB/blob/master/xkb-data_mod/xkb/symbols/extend ):

I my opinion installing Extend is a way easier/cheaper option.

Not with my distro :see_no_evil:

mikkovedru commented 4 years ago

What kind of distro do you have?

Another option is to use VirtualBoxvVMWare, install Linux Mint, Extend and test everything in that virtual installation :-)

NixOS

mikkovedru commented 4 years ago

This issue is not resolved and I have definitely not lost interest. It's just that I can't fix the issue by myself and am at a mercy of other people.

Well, I have no idea how to implement this and I guess @john-preston as well, so, without a person that know how to implement this, this couldn't be implemented.
