HTTP Values

Sent HTTP Values

These values are sent by TclTalkback to the URL:

• All known values for tcl_platform as platform (eg, platform(osVersion)),
• All known values for env (eg, env(HOME)),
• program(-name) (the name of the software),
• program(-number) (the version number of the software),
• program(-license) (type of license this user's app is licensed under),
• program(-expires) (any expiry date it might have),
• program(-users) (the number of users licensed),
• WindowingSys (result of [tk windowingsystem]),
• XLayer (result of [winfo server .]), and,
• ErrorString (error details).

Returned HTTP Values

The script at the Talkback URL may optionally send a header in the form of:

X_TclTalkback_URI: URI

This URI can be any acceptable location which a browser can open. For example:

X_TclTalkback_URI: http://www.example.com/moreinfo/10234/
X_TclTalkback_URI: https://www.example.com/bugs.cgi?view=20
X_TclTalkback_URI: ftp://www.example.com/pub/docs/2007-045.pdf

TclTalkback will then open this URL on the user's browser.

Where this header has not been set, TclTalkback will use any content from the HTTP page as the content of a text-format informational dialog.

Alternately, you can override this behaviour by using ::tcltalkback::Settings -finishinfo text.
