Renders the JavaScript code snippet for event listeners registered for the peer widget.

Specified by:

renderWidgetListeners in interface ContentRenderer

Parameters:

listeners - the map of listeners to register at the peer widget. The key is the event name (such as onClick), and the value the code snippet (such as this.getFellow('inf').setValue('new')). They are both String instances.

renderWidgetOverrides

public void renderWidgetOverrides(java.util.Map<java.lang.String,java.lang.String> overrides)

Renders the JavaScript codes snippet to override the methods and properties of the peer widget. This method uses the widget's setOverrides method (at client), so, if the value is a method, it will preserve the previous method as '$' + method_name

renderWidgetOverrides in interface ContentRenderer

Parameters:

overrides - a map of methods and properties. Notice that the value must be a valid JavaScript snippet that can be evaluated to a value. In fact, the map will be generated as follows.
{name1: value1, name2: value2}. Examples of values: function () {}, 123, new Date(), and "a literal string"

renderWidgetAttributes

public void renderWidgetAttributes(java.util.Map<java.lang.String,java.lang.String> attrs)

Specified by:

renderWidgetAttributes in interface ContentRenderer
