#Example script: How to capture button output and make actions based on the results

/usr/local/bin/dialog \
    --title "Example Button Click" \
    --message "This script will capture the exit code of the Dialog process, which indicates what action the user took.\n\n Dialog disables button 1 for 3 seconds by default when using a timer." \
    --icon "SF=bolt.circle color1=pink color2=blue" \
    --timer 15 \
    --button1text "Button1" \
    --button2text "Button2" \
    --infobutton "Button3(Info)" \

# Capture the exit code of the previous command in a variable
# Very important that this part comes immediately after the dialog command
dialogExitCode=$?

# Print the exit code to standard out:
echo "Dialog exit code is: $dialogExitCode"

# Case statement to determine actions based on the exit code. This could also be an if/elif/else block, but case is more readable.
