Problem You have set up and changed the fonts of the menuitems in Part 1.
However, as noted in Part 1, the fonts of the radio menuitems are not changed as shown below:
We will fix this in this Part 2 as shown below:
Solution
- For standard menuitems, we can get the pointer to the underlyiing GtkLabel using
$menu_item->child.
- For radio menuitems, we get the poitner to the label corresponding to each radio menuitem with $radio[$i]->child.
- Once we have the label to the radio menuitems, we set the font as usual with GtkWidget::modify_font().
