Overview

The code example given below is used to make the Alarm list window in Qt.Here in the below code I have used this QLabel, QCheckBox, and QTimeEdit widgets to make the page of Alarm list in Qt. Also I have connected the QCheckBox with the QTimeEdit using signal and slot mechanism. For more information go to this link.Understanding_signal_and_slot_in_Qt

Prerequisite

  • Here it is assumed that a user had properly set the Qt application development environment. And also Qt SDK for windows is also installed.
