The style of the GUI of FlightGear, in essence the menus, most dialogs and their widgets, uses styles that can be changed or modified after taste.
The GUI of FlightGear
See PUI for the main article about this subject.
For the graphical user interface (GUI) in FlightGear uses PUI, the Picoscopic User Interface, one of the PLIB libraries.
The GUI style can be customized to a certain degree by changing the appearance (colors and transparency) of all major GUI widgets (such as buttons, text fields, sliders, checkboxes etc.), so that different GUI styles can be created. The style of of the GUI is configured through PropertyList XML files.
As of FlightGear 2.6 there are two different GUI styles provided in the base package:
You can switch between GUI styles with Main Menu > Debug > Cycle GUI Style. Press F10 if the main menu is hidden.
