It's been awhile since I've used jbox but if it behaves like dbox then typically you need to somehow trigger the drawing. I believe there is a method called lineon() that you would call to get into that mode.
The way I've done this is by using a measure button that calls the lineon() method. There's also a lineoff() method. You may also need to set verbose to true when you initialize the applet. Assuming you have a jbox called myBox, then you could test with: Measure: <a href="myBox.lineon()">on</a>/<a href="myBox.lineoff()">off</a> Steve >>> Alexandre Abramides <[EMAIL PROTECTED]> 03/14/06 8:56 AM >>> Anyone? ----- Original Message ----- From: "Alexandre Abramides" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Tuesday, March 07, 2006 1:55 PM Subject: [UMN_MAPSERVER-USERS] JBOX - distance measuring > Anyone can help me? > > I,m trying to use the distance measuring function from jBox. > This is the javascript function in > http://mapserver.gis.umn.edu/docs/howto/jbox > > function measure_handler(name, s, t, n, a) { > // c = 1 / 72dpi / 12inches_per_foot * 1.0003state_plane_scale_factor > var c = 0.0011577546296296; // constant > var f = [scale] * c; // scale factor > if ((s>0) || (t>0)) { > defaultStatus = "This segment = " + s*f + ", Total = " > + t*f + ", Number of vertices = " + n ; > } > } > > and I don´t know what else i have to do. > Should i add another "mode" to my html template?
