Re: Blaxxun - display script in browser status line

Hi:

The code in your example appears to be correct.
The problem is that you commented out lines that write
the string to the browser status line.

This is the code that is in the file lib_SO_proto.wrl, as downloaded
from your site:

# Blaxxun version
DEF display_Message Script {
field SFString labelString IS objName
eventIn SFBool set_boolean
url [
"java script:
function set_boolean (bolValue) {

// Set popup label
// if( bolValue == true ) { Browser.setDescription(labelString); }
if( bolValue == true ) { Browser.print(labelString); }
// Syntax - for Blaxxun compatibility - remove if ... else statement
// if( bolValue == false ) { Browser.setDescription(''); }
if( bolValue == false ) { Browser.print(''); }
}"
] # end url
# Output events for browser router are implied
} # end Script

Note that the Browser.setDescription(...) lines have been commented out
in that file. If you uncomment those lines, then the Names of the objects
are written to the Browser status line when Blaxxun Contact is the plug-in.

Thanks. I am downloading the Blaxxun documentation manual, so
hopefully that will reduce the number of questions I have been posted.
Along these Blaxxun lines:

Q1. To maintain cross-browser capability, is there a method to
encapsulate Blaxxun unique syntax in a function that only Blaxxun will
read, but the other browsers will pass over? I thought I saw something
posted here that was using a "vrmlscript:" tag.

Q2. When should I be concerned about shared vs. single-user behavior
when writing for the Blaxxun multi-user environment? The "on-touch"
sensor discussed above is intended to display only on an individual
user's screen and not be a shared behavior. I am trying to port a
light-weight low-behavior version of my astronomical plotting mini-app
that might also work under Blaxxun. The "on-touch" behavior is to
allow individual users to identify objects, but would not be expressed
to multiple users.

Whatever tips the group can provide would be appreciated.

Regards - Kurt

P.S. - Point-of-information. Under Contact and MS IE 6.0, the
"on-touch" sensor action does not display in IE's status line; it
displays in the Blaxxun console - which is acceptable behavior for my
purposes.

"vrmlscript:" is a "cosmo"ism that is equivalent to "java script:"

You can find it in output from cosmo-tools like some cosmoworlds versions,
but usually "vrmlscript:" is outdated.
