XFCE 2 state launcher conundrum

Galik · 08-04-2004, 06:16 AM

Hi.
I wondered if anyone out there knew how to use the 2 state launcher in XFCE. Basically I want to create a launcher that mounts/unmounts my usb drive. Not I guess I need to write a script to do the mounting/unmounting but I'm confused as to how the script should work. How does the launcher determine whether to display the on or off icon? Does my script need to return a particular value for that? How does my script differentiate between a click on the launcher from the mouse from the launcher just polling the script to detect the state of the icon (on or off). Or is it all something else entirely?

It would be really good to get my usb drive mounting/unmounting and reflecting it's state so any help would be appreciated.

Okay after a bit of dipping into the source code and some experimentation I have a working script

I'll post it here for future googlers to find

Basically when you click on the launcher in xfce's panel the script is called with either a "1" or a "0" added as a parameter. When the launcher is just querying the script no parameters are added and the output of the script is collected (it needs to be a "1" or a "0".

So here's the basic script...

Code:

#!/bin/sh

# mount
#  0 -> success
# 32 -> failed to mount

mpoint="/mnt/usb"
action=${1}

if [ $# -gt 0 ]; then


	if [ ${action} = "1" ]; then

		mount ${mpoint} > /dev/null
		err=$?
	
		if [ ${err} -eq 0 ]; then

			#echo "success"
			echo "1" > ~/.usbmount

		fi


	else

		umount ${mpoint} > /dev/null
		err=$?
	
		if [ ${err} -eq 0 ]; then

			#echo "success"
			echo "0" > ~/.usbmount

		fi
	fi

else

	cat ~/.usbmount

fi

This can definately be improved upon. Don't hesitate to post it here if ou do

Well Done.
This script works very well.
