zenity dialog window with two buttons but no text entry

Question

I would like to create a zenity dialog window with two buttons as only user input.

The following creates a window with two buttons but with a space for a text entry

zenity --entry --title="" --text "Choose A or B" --ok-label="B" --cancel-label="A"

The following creates a window with one button only

zenity --info --title="" --text "Choose A or B" --ok-label="B"

Answer 1

--question is what you are looking for:

zenity --question \
--title="" \
--text "Choose A or B" \
--ok-label="B" \
--cancel-label="A"

You may also try:

zenity --question \
--text="Choose A or B" \
--switch \
--extra-button "A" \
--extra-button "B"

This automatically generates a dialog with just your two extra buttons. (--switch suppresses the default OK and Cancel buttons)
