Ringhio Notifications ProgressBar Example

Introduction

This is a basic example in C of how to use the latest Ringhio Notifications to display a notification bubble displaying an incrementing progress bar.


It can be reused in many applications where the progress of a file operation can be monitored in the background by the user and does not need to be displayed in focus or inside a window.


The source code example below the progress bar gradually increments whilst the bubble remains open on screen. It requires the latest Ringhio Notifications and ProgressBar Gadget Class to be installed.
