[Fraser Burgess]

Thanks Brian and Chris.

 

Using the function GetParent() code below has solved my problem.

 

Cheers,

Fraser

If you want to add the reference to your fusion index page, add the
following to your aspx (task pane) page

 

function GetParent()

        {

            if (parent.Fusion) {

                return parent;

            } else if (parent.parent.Fusion) {

                return parent.parent;

            }

   }

 

Then you can call functions in the same way as before but substitute

 

GetParent().DigitizePoint(OnPointDigitized);

I think you should be able to reference the MapGuideViewerAPI.js script
from your aspx page, and then just call DigitizePoint directly without
any window.top or parent references.

 

It should also be possible to add a reference to MapGuideViewerAPI.js to
the index.html file in the Fusion template you're using, and reference
it using window.top...

 

It's been a while since I've played around with this stuff, so someone
else may be able to provide specifics...

Hi List,

 

I'm making steady progress with my project and learning many things
about MapGuide along the way thanks largely to the help from those on
this list - many thanks to those who have helped so far

 

>From what I can tell parent.parent.parent.mapFrame is how the map frame
is referenced from the task pane in the AJAX viewer.  I have been
reading posts about how this is referenced in Fusion and it seems the
MapGuideViewerAPI.js file has a bit of info.  Unfortunately I'm having a
bit if trouble putting the pieces together and was hoping that someone
here may steer me in the right direction.

 

In both AJAX and FUSION I'm working from the taskpane and using the
markup scripts that are part of the AJAX demo's and tutorials.

 

I assume I need to substitute either 'Fusion' or 'window.top.Fusion'
somehow for
'parent.parent.parent.mapFrame.DigitizePoint(OnPointDigitized);'. in my
script however I have yet to do this in such a way that it works.  I
keep getting 'Object doesn't support this property or method'.

 

So for example in my editmarkup.aspx code for example, I have the
following function which should be activated when I click the digitize
point button

 

            function AddPoint()

            {

                  SetDigitizeInfo(EDIT_POINT_HELP);

 
parent.parent.parent.mapFrame.DigitizePoint(OnPointDigitized);

            }

 

In Fusion this code gives an error 'parent.parent,parent.mapFrame' is
null or not an object

 

I see that in MapGuideViewerAPI.js

 

function DigitizePoint(handler) {

    if (handler) {

      var Fusion = window.top.Fusion;

      var mapWidget = Fusion.getWidgetById(mapWidgetId);

      var digitizer = new Fusion.Tool.Canvas.Point(mapWidget);

      digitizer.mouseUp = PointHandlers.prototype.mouseUp;

      Object.inheritFrom(digitizer, Fusion.Tool.Canvas.prototype, []);

      digitizer.initializeCanvas();

      var activeWidget = mapWidget.buttonSet.activeButton;

      mapWidget.buttonSet.setActiveButton(null);

      digitizer.handler = function() {

          handler.apply(null, arguments);

          activeWidget.setActive(true);

      }

      digitizer.activateCanvas();

      

      //add a listener to update the position of the features

      var mapWidget = Fusion.getWidgetById(mapWidgetId);

      mapWidget.registerForEvent(Fusion.Event.MAP_EXTENTS_CHANGED, 

        function(){

          digitizer.updatePx();

          digitizer.clearContext();

          digitizer.draw(digitizer.context);

        }

      );

    }

}

 

Thanks

Fraser
