[mapguide-users] Autodesk Help - OnSelectionChanged

[Walt Welton-Lair]

I spent some time investigating this to see if I could reproduce what
you were seeing (the selection event working for AJAX but not for DWF).
 
I first tried it with the latest code (in the OSGEO vault), and the
mainframe's OnSelectionChanged handler was getting called for me when
using DWF Viewer.  I then reverted to the MGO 1.0 code, and it still
worked.  Finally I tried RC1, and it also worked.
 
For the tests above I was using a pre-release build of DWF Viewer 7
(which addresses the ActiveX activation issue).  Thinking that could be
a factor, I reverted to DWF Viewer 6.5.  Once again it was working in
all cases (latest code, 1.0, RC1).
 
For my test all I did was add some alerts statements to the
OnSelectionChanged handlers and verified these were popping up.
 
I'm not sure why you guys are having problems with this.  I covered all
the cases I could think of and didn't have any problems.
 
Note that adding code to the mainframe's OnSelectionChanged handler is
correct, since this handler is common to both AJAX / DWF.
 
BTW, if you do get it to work you'll find there's a bug with the current
DWF Viewer's OnSelectionChanged event: the event gets raised every time
you click in the map (the selection object stored by the viewer is
getting replaced, but no check is done to see if the set's contents are
actually different).  This is fixed in DWF Viewer 7.

Juan,
 
I am in the un-documented realm I think.
 
I am actually making additions to the mapviewer code.  Here:
 
C:\Program Files\MapGuideOpenSource\WebServerExtensions\www\mapviewernet
C:\Program Files\MapGuideOpenSource\WebServerExtensions\www\viewerfiles
 
Some of it is documented in the Web API as functions you can call from
your application.
Others are internal functions.
 
Cheers,

Hey Kori:

 

Where did you see the documentation for the "OnSelectionChanged" event?
I'm looking for the event handlers in MGOS that are similar to the ones
I used with MG 6.x.   Thanks.

 

- Juan

Hi All,

 

Outstanding issue with some changes:

 

I need to call a function from the OnSelectionChanged event in the
mainframe.templ of the mapviewer/mapagent.

I have a javascript function in the mainframe.templ file itself.

 

In MGO RC 1:

 

I called my function from the OnSelectionChanged event - and it worked
smooth.

 

In MGO 1.0:

 

The code changed for both the AJAX and DWF viewer.

i.e. ajaxmappane.templ and dwfmappane.templ respectively.

 

The function call from the OnSelectionChanged no longer worked.

 

I have been fiddling trying to get it working again and have had success
with the AJAX viewer but not the DWF Viewer.

 

 

For the AJAX viewer:

 

In the ajaxmappane.templ file;

In the ProcessFeatureInfo() function - I call my function.

 

Works like a charm.  Everytime I select, the function is executed.

 

For the DWF Viewer:

 

It now has that emaprelayer.html with an OnSelectionChanged event.

 

I try calling my function there:

      parent.parent.myfunction();

- doesn't work.

 

I try calling it from the OnSelectionChanged event in mainframe.templ.

       myfunction();

- doesn't work.

 

Doesn't work means stopping IIS, MapGuide Server - editing and saving -
then restarting.

 

Can someone from Autodesk point me in the right direction?  

 

This is critical to mirroring 6.5 functionality in our clients
applications.

 

Cheers,
