Explanation The above example is based on How to display a 2D array in table - Part 4?.
What's new here:
- Note that we declare GtkTooltips in the global level. If you declare it inside the
function display_table(), you will find that the tooltip won't be displayed.
- Don't forget to place the label in the eventbox before adding the tooltip to the eventbox with GtkTooltips::set_tip().
