With the 0.9 release, as part of refactoring to allow mapguide-react-layout
to reuse the existing Fusion backend, I had to implement polyfills for
Fusion APIs that the
query/theme/redline/featureinfo/selectwithin/buffer/search widgets use.
Which also meant I had to polyfill support for some
Also take care that any selection handlers you register be unregistered
(either manually or on page unload) as well to prevent "dangling" event
handlers if you load other task pane content in from running another
command.
The samples page demonstrates this.

I've yet to implement a more generic event handler that covers most/all of
the Fusion events. This is the logged issue.

Hi, I placed this viewer in an iframe named "mapframe" and it works!
var myviewer = mapframe.GetViewerInterface();
and
mapframe.RegisterSelectionHandler(mySelectionHandler);
That's what I wanted!
Can I declare other handlers (MapLoaded etc.) without modify the viewer
sources?
Thanks, svlad
I've just landed support so that task pane content can install/uninstall
selection change event handlers.
If you want to try this out right now (instead of waiting for me to release
0.9), grab the latest viewer.zip from the AppVeyor artifacts page:
You raise an interesting point about how our viewer offerings are being used.
Namely, I wasn't expecting embedding the viewer in a frame/iframe to feature
prominently as a common use case. The viewer API design thus far has been
going on the assumption that the react viewer is either the
Hi, we use nearly all fusion events (MAP_LOADED, MAP_SELECTION_ON,
MAP_SELECTION_OFF etc.) from outside (the fusion viewer is in an iframe).
Will this be possible with the new react-layout?
Thank you, svlad

That sound's great.
I think, this is a good solution.
Thank you in advanced.

Thanks for the link, it makes it more clear what you're trying to achieve.
I think the easiest thing is for me to add a new viewer API to register a
handler for selection changes. It will be at the same level as other AJAX
viewer APIs, so you can get to it from the task pane content through
I thought about this some more.
Since your aim is to ultimately be showing some kind of URL the task pane
(or new window, or frame) in response to a selection, and my aim is for this
viewer to be as much configuration-driven as it possibly can be (I want
custom coding to be a last resort solution
If it is possible, yes.
For what I need this:
As soon as the user touches/clicks on the map and occurs a change/creation
of a selection, the user will get a custum property info in the taskpane
with more properties than in the mapguide propertypane.
For this, I just need an event that the
There is no current hook to the outside (of react.js) world for map selection
changes.
It should be trivial for me to add such a hook as a mount() call option if
that is what you're after.
