Examples
// add an inline function as an event listener
parasql.app.getWidgetById('ID1007').addEventListener('render','function (event) { event.target.getContentDiv().innerHTML = "Inline Hello World"; }');// add a function call as an event listener
parasql.app.getWidgetById('ID1008').addEventListener('render','renderHelloWidget');// add an object as an event listener; the object must implement handleEvent(event)
document.myClass = new MyClass();
parasql.app.getWidgetById('ID1009').addEventListener('render','document.myClass');getContentDiv() → {HTMLDivElement}
Typically your code will call this method after it receives a render event.
