Changing Font Sizes In The NetBeans IDE

I was working on the NetBeans IDE in one of the systems I recently upgraded to Gnome 3.x, the font size in the left nav-bar was way to small, changing the font size in the options menu, only helped modifying the code window font size, but not the nav-bar window tree size. Below is a screen-shot with my font issue. One of the options/workarounds that worked for me is, starting Netbeans with the –fontsize option, something like the below should help.

/opt/netbeans/bin/netbeans --fontsize 22 --laf javax.swing.plaf.metal.MetalLookAndFeel

Below is a screen-shot with –fontsize option, adding the font size changed/fixed the issue. While this workaround worked for the Metal them, it did not work with the GTK+ them. Do you know of a workaround for the GTK+ them? please let me know in the comments below. You might also like How to add a new launcher/shortcut in Gnome 3.x.
