Description

The description of this issue was copied from GUAC-1480, an issue in the JIRA instance used by the Guacamole project prior to its acceptance into the Apache Incubator.

Comments, attachments, related issues, and history from prior to acceptance have not been copied and can be found instead at the original issue.

Thanks to recent improvements in browser handling of clipboard, direct integration of the local clipboard is now possible. Cut/copy via the keyboard can be written to work in all cases, while the general case will require either:

1. The Chrome Allow Clipboard extension. Our Clipboard Permission Manager extension.
2. Browser support for prompting for clipboard permission upon use of the standard execCommand() (currently only IE11).

The situation for Chrome, Firefox, etc. is suboptimal, but still far better than before, there is hope that other browsers will follow the mechanism used by IE11 and allow webapps to request permission. The negative effects of the old style of clipboard integration are no longer an issue.

IMPORTANT

For this integration to be acceptable, it MUST NOT disturb the remote clipboard except when the local clipboard actually changes. It would be extremely frustrating if the user copies something not supported for the Guacamole clipboard, like a file, only to find it immediately overwritten by the text they copied previously.
