Explanation We make use of the code in How to set valign top in GtkTable? to display a 2D array.
What's new here:
- Create a GtkHBox and stuff it inside the vbox. Note the use of
0, 0 to prevent any expansion or filling.
- Create another empty GtkVbox and turn on expansion and filling so that it will "push" the vbox to the left.
