Clipboard support using guacamole-common-js API
Hi,
First of all, I want to say Guacamole is great and I appropriate the work
and efforts you invest in it.
I am implementing a Guacamole client using guacamole-common-js API, and I
would like to add clipboard support. I understood from the official
documentation that clipboard is currently supported only by the web
application and not by the API.
Can you please guide me how to implement it myself?
If you can point me to some code that does it already it would be great.
Thanks,
Dave

Hi Amarjeet,
Can you post detailed steps how to achieve this ?

Hi Mike,
I tested again and again. It works in Chrome and Firefox and IE.
ISSUE : Microsoft Edge hangs. I am trying to debug it but couldn't find
anything.
I want Guacamole Team to look into it if possible.
Do I have to fork a test feature and push it in Github to review by
Guacamole team.
or there is any other way ?

Amarjeet Singh

Hi Mike,
I enabled Ctrl + V ( Paste Event ) >> then updated the guacClipboard
<< $scope.$broadcast('guacClipboard', data); >> .
Issue : It was sending Ctrl + V keys to the server and then the clipboard
data , therefore server is pasting older data and on the next Ctrl + v , it
is pasting the correct data.
I stopped the guackeyDown broadcast <<
$scope.$broadcast('guacBeforeKeyup', keysym, keyboard); >> only for Ctrl +
V and first sent the clipboard data to the server, now data is updated on
the server >> then used guacSyntheticKeydown to send ctrl and V keys .
It is copying the correct data but with an issue.
Issue : Suppose I have this text on the Notepad of the remote server "
Guacamole | " , As you see the cursor is after the space, when I paste
text "amarjeet" from local to remote it becomes
"Guacamoleamarjeet" : The space is not there.
Please share your suggestions. I would be very grateful to you.
I am looking into it.
Thanks and Regards,
Amarjeet Singh

Please do not post the code of proprietary software here (or elsewhere).
Doing so is most likely a copyright violation.

It's good to check against the main Guacamole web application
regarding implementation details and possible solutions, but beware
that the functions you refer to are not part of guacamole-common-js,

This code looks minified, and references functions which are not part
of Guacamole. Where did you copy this from?

Re: Clipboard support using guacamole-common-js API
Posted by Amarjeet Singh <am...@gmail.com>.
Hi Dave,
Please dig into *getLocalClipboard()* function in guacamole-common-js API,
once data is copied to *clipboardContent *it broadcast to *guacClipboard *i.e.
Guacamole menu.
*windows.clipboard* events only work in IE not in any other browsers.
In Google Chrome we can use paste event to get clipboard access.
document.addEventListener('copy', function (ev) {
> var selection = window.getSelection().toString();
> // Transform the selection in any way we want.
> // In this example we will escape HTML code.
>
> // Place the transformed text in the clipboard.
> ev.clipboardData.setData('text/plain', selection);

> Date);

I am not sure how to implement it in Chrome and Firefox but the following
