1. Getting Started with a Simple Project

Link the Widget

Input widgets can be configured to control an output widget. To do this, just click

on the input (in this example, the slider widget) and go to its Object Inspector

Section and click the Events Tab.

There are two events available under the events tab of an input widget -

OnChanged and OnChanging. These events are triggered by touch actions

performed on the input widget. The OnChanged event is triggered every time an

input widget is released. On the other hand, the OnChanging event is continuously

triggered while an input widget is being touched. In this example, the OnChanging

event is used. Set the event handler by clicking on the ellipsis symbol for the

OnChanging event handler.

The on-event selection window appears. Select coolgauge0Set, then click OK.

Configure the Input Widget to Send Messages to a Host

An external host, connected to the display module through the serial port, can be

made aware of the status of a widget. This can be achieved by configuring the

widget to send event messages to the serial port. To do this, set the OnChanged

event handler of the slider widget to Report Message.
