-----------------------------------
Many widgets are simple specialisations of existing widgets. For
-example, the `Record` widget is the same as the `Records` widget
-except that it defaults to displaying a single record. It's defined as
-follows:
+example, the `images` widget is the same as the `records` widget
+except that it defaults to using the `images` template for displaying
+its result list. It's defined as follows:
- mkws.registerWidgetType('Record', function() {
- mkws.promotionFunction('Records').call(this);
- if (!this.config.maxrecs) this.config.maxrecs = 1;
+ mkws.registerWidgetType('images', function() {
+ mkws.promotionFunction('records').call(this);
+ if (!this.config.template) this.config.template = 'images';
});
Remember that when a promotion function is called, it's passed a base
the promotion function that's been registered for that type.
Once this has been done, the specialisations can be introduced. In
-this case, it's a very simple matter of changing the `maxrecs`
-configuration setting to 1 unless it's already been given an explicit
-value. (That would occur if the HTML used an element like `<div
-class="mkwsRecord" maxrecs="2">`, though it's not obvious why anyone
-would do that.)
