Issue
I need to change DVT eclipse menu size. also in properties view and Project Explorer.
High DPI make them larger than the code font size.
Although this soultion did work it was complicated and change only the Project Explorer (without Menu and Project)
DVT Version - dvt_eclipse_20.1.37-e46
Solution
As mentioned in DVT "Themes" documentation page.
To change the fonts, please go to Window > Preferences > DVT > Themes.
You will find there the option to change both the Editor Font and the UI Font (the second one is what you are looking for)
