Explanation
- Create a GtkHBox to hold the buttons.
- Wrote a small function to simplify the creation of buttons.
- Set the size of the button.
- Set the background color of the button.
- Add the button to the hbox
- Add an event handler to respond to button click.
- This is the callback function that is called when the user clicks the button.
Notes
Setting the background color of a GtkButton is relatively easier than setting the background color of a GtkLabel.
To set the background of a GtkLabel, please refer to How to set the background color of GtkLabel?
