Argent Stonecutter proposes the following idea in the Second Life Jira system at https://jira.secondlife.com/browse/VWR-394
Second Life Viewer – VWR-394
LSL function to access the HTML floater for more capable dialogs.
There have been a number of sugestions for extending the dialogs in SL. Here’s a much easier way to get the same functonality, with minimum server-side changes required: An llHTMLWindow request that would, if you had PERMISSION_OPEN_WINDOW (which could be automatically granted to attachments) open a window displaying an HTML page assembled by the script. Almost everything required to implement it is in place:
The response would come back in chat as a URL-encoded string, similar to a CGI “GET” response: “name=value&name=value&…”. Parsing this in a listen event would be easy, given llUnescapeURL():
Sounds like a good idea to me. I voted for it. Perhaps you should too.
