Exclusive API for Drop-down Box Widget

Difference from V10.0:

Added the setName4Empty API.

Example 1: You can modify the default text in the widget drop-down list to Select All when the obtained drop-down box widget object is defined as combo.

combo.setName4Empty("Select All");

Example 2: In a general report, you can modify the default text in the drop-down list of the drop-down box widget named comboBox0 on the parameter panel to Select All.

_g().getParameterContainer().getWidgetByName("comboBox0").setName4Empty("Select All");

Example 3: In a dashboard, you can modify the default text in the drop-down list of the drop-down box widget named comboBox0 in body to Select All.

 _g().getWidgetByName("comboBox0").setName4Empty("Select All");

Note: 

If an error occurs due to incomplete creation of the report block object after adding the event, you can add a delay function to postpone the execution.

setTimeout(function(){    _g().getParameterContainer().getWidgetByName("comboBox0").setName4Empty("Select All");}, 500);

You can modify the default text in the drop-down list of the drop-down box widget to Select All.
