Add your own buttons to wbar

(1/2) > >>

bigpcman:
Here's how I did it. I just added my information to /usr/share/wbar/dot.wbar. There are three entries per button:
i: = image
t: = text
c: = command
Then make dot.wbar persistent using the backup system or by creating a custom tce extension containing all changed system files.
Note the png is 48x48 pixels at 72 dpi.


--- Code: ---# The Bar && Font && Font size (11)
i: /usr/share/wbar/osxbarback.png
t: /usr/share/fonts/luxisr/11
c:
i: /usr/share/wbar/aterm.png
t: Aterm
c: exec /usr/bin/aterm
i: /usr/share/wbar/cpanel.png
t: Panel
c: exec /usr/bin/cpanel
i: /usr/share/wbar/appbrowser.png
t: Apps
c: exec /usr/bin/appbrowser
i: /mnt/sdc1/mywbar/samba-wbar-active.png
t: S
c: exec /mnt/sdc1/mywbar/samba-wbar &

--- End code ---

My button toggles between two colors to show the state of the program that gets activated by displaying two different images. The script below (samba-wbar) uses three images on, off and active to support the toggle function.


--- Code: ---#!/bin/sh
#bigpcman May 28, 2009

 start(){
  /mnt/sdc1/samba/samba_server start 2>&1 > /dev/null &
  sleep 4
  sudo cp -f /mnt/sdc1/mywbar/samba-wbar-on.png /mnt/sdc1/mywbar/samba-wbar-active.png 2>&1 > /dev/null &
  /usr/bin/wbar.sh 2>&1 > /dev/null &
 }

 stop(){
  /mnt/sdc1/samba/samba_server stop 2>&1 > /dev/null &
  sleep 4
  sudo cp -f /mnt/sdc1/mywbar/samba-wbar-off.png /mnt/sdc1/mywbar/samba-wbar-active.png 2>&1 > /dev/null &
  /usr/bin/wbar.sh 2>&1 > /dev/null &
 }

 PID=$(pidof smbd)
 [ -n "$PID" ] && stop || start

--- End code ---

edit: Note the "active image" should be  initialized by a custom tce or by a cp command in the bootlocal script to make sure it is in the correct state after a bootup.

I think that (just the samba portion) goes into /usr/local/tce-icons as a separate file that will load/unload  with your samba extension

That's an interesting point, tcz.uninstall samba3 would not remove the icon from the wbar unless it was in /usr/local/tce-icons. I wonder how the tcz-uninstall tool would know which icon to remove since I put it there "manually" as opposed to the smaba3.tcz installer. Perhaps it would need a "special name? Actually the tcz.uninstall tool would have to know to remove the entire dot.wbar entry. How would it know to do that? My preference would be to add a wbar removal function to my samba manager script.

edit: I don't know what I was thinking here, I went way off track with my answer. I never want my "button" to load or unload with samba since it is responsible for managing samba (install/uninstall and start/stop)! This button is a system level button for me and should always be present.  :-X

You should avoid modifying the system file and use the already supported /usr/local/tce.icons area. Perhaps you should request that your mods be included in the samba extension rather than adding to an already complex situation.

For custom wbar buttons in general, buttons that just run a script, if I put them in tce.wbar "manually" how do I make them persistent. I have tried a few things and it looks like I would have to make a "dummy" tce to get my entries into tce.wbar. Putting my entries in dot.wbar removes this complexity.
