Phone Widget
The Phone widget is used to call a phone number in an application using the phone app of your device.
A Phone widget, when placed in an application, allows you to launch the native phone dialer, and initiate a phone call to the number that is displayed on it. It appears as a button on the Form, and the phone number is displayed on it either in the number format or the phone spell text. When the user selects the phone widget, the native phone app is launched to make a phone call.
Following are the real-time use cases of the Phone widget:
-
Used in business websites where the contact numbers are displayed.
-
In apps that offer services such as delivery of food, medicines or electronic gadgets; rider’s contact details are displayed using Phone widget. Customers can call the rider to know the status of the delivery.
-
Contact support in websites.
Widgets are normally added to your Kony application using Kony Visualizer, but can also be added from code. For general information on using widgets in Visualizer, see Designing an Application in the Kony Visualizer User Guide.
For general information on the Phone widget see the Phone topic in the Kony Visualizer User Guide.
