Amarjeet Singh commented on GUACAMOLE-517:
------------------------------------------
Thanks Mike for guiding me out .
Can we send the PrintScreen keydown and keyup event to remote desktop on keyup
event only in scenario of PrintScreen key.
Browser do handle the PrintScreen keyup event. I have already tried it in the
past but at that time scancode does not exist in the guacamole-server.
We can give it a try and it will add PrintScreen feature for Windows RDP as
well.
User's who want to take the screenshot of their screen, usually they press
PrintScreen.
Please do suggest any idea about it or any guidance.
> Print screen key definition missing from RDP base keymap
> --------------------------------------------------------
>
> Key: GUACAMOLE-517
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-517
> Project: Guacamole
> Issue Type: Bug
> Components: RDP
> Affects Versions: 0.9.14
> Reporter: Amarjeet Singh
> Priority: Trivial
>
> The scancode mapping for the "Print Screen" key is missing from the base
> keymap used by Guacamole's RDP support. This means that although Guacamole
> and usages of guacamole-common-js should correctly map the "Print Screen" key
> to its corresponding keysym (assuming the key is not intercepted by the OS),
> that keysym will not be transformed into the scancode required by RDP.
> The necessary mapping needs to be added such that the correct scancode and
> flags are sent to the RDP server if the "Print Screen" keysym is received.
