Instead of creating my buttons and waiting for me to press them to
execute they are executing when I create them and won't do my callback
when I press them.. thanks for any help in advance
button[num] = Tkinter.Button(frame,text = returnstring,
command=callback(returnstring))#
this line executes on creation
my output on startup is (should output when I choose an option)
1 String pad
10 Chorus
25 Reverb
30 Mixer
The buttons do label correctly.
title = 'csd instrument list'
# Import Pmw from this directory tree.
import sys
sys.path[:0] = ['../../..']
import Tkinter
import Pmw
import csoundroutines
class Demo:
def __init__(self, parent):
frame = Tkinter.Frame(parent)
frame.pack(fill = 'both', expand = 1)
button = {}
instr = [[]]
instr = csoundroutines.csdInstrumentList2(sys.argv[1])
num = 0 #instr_number
buttonBox = Pmw.ButtonBox(parent)
for i in range(0, len(instr.instrnum)):
num += 1
returnstring = instr.instrnum[i] +' '+ str(instr.comments[i])
#printstring = zz + x[num]
button[num] = Tkinter.Button(frame,text = returnstring,
command=callback(returnstring))#kinter.Buttonstr(x[0]) + ' ' + x[1])# +
comments)
button[num].pack()
#returnstring = zz
button[num].grid(column=num, row =
0)#,command=callback(returnstring))
#button[num].pack()
frame.grid_rowconfigure(3, weight=1)
frame.grid_columnconfigure(3, weight=1)
frame.pack()

print text
