[fusion-users] Non-visual widgets

[Chris Claydon]

I'm not sure this is the best approach, but could you extend the existing selection widget to add in the new code (either by modifying it directly or by creating a new widget based on it)?

I don't want to modify the actual mapguide templates to accomodate this widget, can it be stored within a container, even though it has no visual appearance?

Yes, the Maptip widget might be an example of this.  It does have some 
visual output but there is no buttons or anything to start/stop it.

You would put it in the AppDef, with a <Type> that corresponds to what 
you called the widget, e.g. Fusion.Widget.MyWidgetType would have <Type> 
set to MyWidgetType.  For the <Name> element, I think you need a 
corresponding HTML element in your template, but that can be an empty 
hidden element.  Paul can correct me if I'm wrong about that.

I don't think there is support for this in Studio so you would have to 
code that by hand in your AppDef.
