This download contains an example implementation of a statusbar. The statusbar has the following features:
File to display the system time
Icon to show that a USB connection is present. Can be clicked if it's shown.
Icon to show that an SD-Card is present. Can be clicked if it's shown.
Icon to show a settings dialog.
Note that this widget is very application specific. It should be modified as needed to fit the target application.
The download also contains a ready-to-run example project.
The project has not been optimized to use as little resources as possible. Please adjust the configuration to fit your needs!
