-nobuttons command-line option

From The x3270 Wiki

Removes the menu bar from the wx3270 main window.

Also removes all of the options from the main context menu except Copy/Paste/Cut and the keypad. New in 1.2

Its primary purpose, along with specific restrictions and the -noborder command-line option, is to run wx3270 in kiosk mode, where users are unable to modify the appearance or operation of the emulator.

Examples

Start wx3270 with no menu bar.
