Explanation We make use of the code from How to set up menu and radio menu - Part 3 - add accelerators? to set up the standard menu and menuitems.
What's new here:
- Get the pointer to the GtkLabel of each toplevel menuitem.
- Change the font.
- Get the pointer to the GtkLabel of each menuitem.
- Change the font.
- In this example, we change the font of the menuitem to "Times New Roman 12".
Note
The above code runs ok, except for the radio menuitems as shown below:
We will fix this in Part 2.
