; Buttons for Avail and Flush
; ---------------------------------------------------------------
; the buttons which run "avail" and "avail flush"
; Note : we don't have to issue the lvuse and lvadd
; commands - they are only there to make it look nicer..
; The "32m" characters turn on/off the text highlighting.
XBUTTON 171 0 96 16 "Avail"
lvuse pipe.gc 1 ; use the above listview
lvadd "32m----> Avail :31m" ; add a fancy banner (looks nicer)
run 'c:avail >pipe:MyPipe' ; run avail > our pipe
XBUTTON 269 0 139 16 "Avail Flush"
lvuse pipe.gc 1
lvadd "32m----> Avail Flush :31m"
run 'c:avail >pipe:MyPipe flush'

; The PIPE event
; ---------------------------------------------------------------
; This is the xPIPE event that will happen when the above
; avail commands send stuff to our pipe. We'll start it off
; as ON and keep it like that. It will quit when the gui quits.
xPIPE pipe:MyPipe ON
; now here, the internal var $$PIPE.TXT has a line of text
; ready for us. We use our above listview to show it..
lvuse pipe.gc 1
lvadd $$PIPE.TXT
; This event will be called again and again for every line
; that the c:avail command outputs.
