[fusion-users] Startup widgets possible?

[david.wilhelmsson at 65nord.se]

For future reference (for people like me who found this post via Google),
using #2, there is one line missing from the widget definition. Here's the
entire definition:

MySelectionHandler.js:

Fusion.Widget.MySelectionHandler = OpenLayers.Class(Fusion.Widget, {
     target: null,
     url: null,
     initializeWidget: function(widgetTag) {
         var json = widgetTag.extension;
         this.target = json.Target ? json.Target[0] : "TaskPane";
this.url = json.Url ? json.Url[0] : null;
         this.getMap().registerForEvent(Fusion.Event.MAP_SELECTION_ON,  
OpenLayers.Function.bind(this.selectionOn, this));
         
this.getMap().registerForEvent(Fusion.Event.MAP_SELECTION_OFF,  
OpenLayers.Function.bind(this.selectionOFf, this));
     },

     selectionOn: function() {
         if (this.url) {
             var taskPaneTarget = Fusion.getWidgetById(this.target);
             if (taskPaneTarget) {
                 var map = this.getMap();
                 var mapLayers = map.getAllMaps();
                 var params = [];
                 params.push('LOCALE='+Fusion.locale);
                 params.push('SESSION='+mapLayers[0].getSessionID());
                 params.push('MAPNAME='+mapLayers[0].getMapName());
                 params.push('POPUP=false');
                 var url = this.url;
                 if (url.indexOf('?') < 0) {
                     url += '?';
                 } else if (url.slice(-1) != '&') {
                     url += '&';
                 }
                 url += params.join('&');
                 taskPaneTarget.setContent(url);
             }
         }
     },

     selectionOff: function() {
     }

}); 

Here's a widgetinfo that I created for this widget as well:

MySelectionHandler.xml:

<WidgetInfo>
	<Type>MySelectionHandler</Type>
	<LocalizedType></LocalizedType>
	<Description>A widget to call up a URL on selection</Description>
	<Location></Location>
	<Label></Label>
	<Tooltip></Tooltip>
	<StatusText></StatusText>
	<ImageUrl></ImageUrl>
	<ImageClass></ImageClass>
	<StandardUi>true</StandardUi>
	<ContainableBy>Any</ContainableBy>
	<Parameter>
		<Name>Target</Name>
		<Description>The frame, window, or TaskPane in which to display any UI for
the widget. If empty, TaskPane is used</Description>
		<Type>String</Type>
		<Label>Target</Label>
		<DefaultValue>TaskPane</DefaultValue>
		<IsMandatory>true</IsMandatory>
	</Parameter>
	<Parameter>
		<Name>Url</Name>
		<Description>The URL to be opened in the target</Description>
		<Type>String</Type>
		<Label>Url</Label>
		<IsMandatory>true</IsMandatory>
	</Parameter>
</WidgetInfo>

Kind regards,
Dave.
