handle_action
The calendar script is responsible for handling mouse events triggered by your bar, following are valid arguments:
./calendar curr # current month
./calendar next # increment month
./calendar prev # decrement month
Copy calendar to your polybar config directory. Then, in your polybar config, you can use click-left, scroll-up and scroll-down actions to invoke the script. For example:
[module/calendar]
type = custom/script
label = " "
exec = echo Calendar
click-left = ~/.config/polybar/calendar curr
scroll-up = ~/.config/polybar/calendar next
scroll-down = ~/.config/polybar/calendar prev
