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...

Subject: [mapguide-users] parent.parent.parent.mapFrame - AJAX vs FUSION
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

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
