Hi Chris,
I wrote a directory Tree widget a while ago, rather a test than a usable
widget, but maybe good
enough to get started. I had some problems with my release of pybwidget,
because some icons were missing,
I believe the "plus" and "minus" icons for the Tree, but I don't remember
exactly.
So, here's the code:
############ file DirTree.py ##############################
import Tkinter as tk
import bwidget as bw
import os
class DirTree(tk.Frame):
def __init__(self, master, *args, **kw):
tk.Frame.__init__(self, master)
self.tree = tree = bw.Tree(self, opencmd=self.open_folder,
closecmd=self.close_folder, *args, **kw)
tree.pack(fill='both', expand=1)
self.folder_icon =
tk.PhotoImage(file='/usr/share/pybwidget/images/folder.gif')
self.openfolder_icon =
tk.PhotoImage(file='/usr/share/pybwidget/images/openfold.gif')
self.file_icon =
tk.PhotoImage(file='/usr/share/pybwidget/images/file.gif')
node = self.tree.insert('end', 'root', text='/',
image=self.folder_icon, drawcross='allways', data='/')
self.tree.opentree(node, recurse=0)
def close_folder(self, node):
self.tree.itemconfigure(node, image=self.folder_icon)
def open_folder(self, node):
path = self.tree.itemcget(node, 'data')
children = os.listdir(path)
files, dirs = [], []
for item in children:
if os.path.isdir(os.path.join(path, item)):
dirs.append(item)
#else:
# files.append(item)
dirs.sort()
#files.sort()
for item in dirs:
newpath = os.path.join(path, item)
self.tree.insert('end', node, text=item, image=self.folder_icon,
drawcross='allways', data=newpath)
#for item in files:
# newpath = os.path.join(path, item)
# self.tree.insert('end', node, text=item, image=self.file_icon,
drawcross='never', data=newpath)
self.tree.itemconfigure(node, image=self.openfolder_icon)
def test():
r = tk.Tk()
t = DirTree(r, bg='white', selectbackground='blue4',
selectforeground='white', deltax=18, deltay=18)
t.pack(fill='both', expand=1)
r.mainloop()
if __name__== '__main__':
test()

I hope this helps
Michael
