Hello!
I want to learn Tkinter and try to build a small File search dialog. Tkinter
is nice, but here is a problem where I am stuck:
I want to allow the dialog's user to pick a directory. The widget for this
is tkFileDialog.Directory. But when I start the Directory-Window, it is
possible move the focus back to my File Search dialog. Thus it is possible
but not wanted to create several "Pick directory" windows. I tried to make
the Directory instance modal by calling .grab_set() but this raises an
attribute error. Here is a minimal example:
--- snip ---
import Tix
from Tkconstants import *
from tkFileDialog import Directory
class FileSearchBase:
def __init__(self, root):
self.root = root
self.top = None
self.title= "File Search"
def open(self):
if not self.top:
self.create_widgets()
else:
self.top.deiconify()
self.top.tkraise()
self.top.grab_set()
def close(self, event=None):
if self.top is not None:
self.top.grab_release()
self.top.withdraw()
def create_widgets(self):
top = Tix.Toplevel(self.root)
top.resizable(0,0)
top.bind("<Escape>", self.close)
top.protocol("WM_DELETE_WINDOW", self.close)
top.wm_title(self.title)
self.top = top
pickButton= Tix.Button(top, text = 'Pick..',
command = self.pick_dir)
pickButton.grid(row= 0, column=1)
def pick_dir(self):
dir_dlg= Directory()
#dir_dlg.grab_set() # AttributeError: grab_set
#self.top.wait_window(dir_dlg) # AttributeError: _w
dir= dir_dlg.show()
print dir
if __name__ == '__main__':
root = Tix.Tk()
root.title("File Search Demo")
widget = FileSearchBase(root)
searchButton = Tix.Button(root, text = 'Show search dialog',
command = widget.open)
searchButton.pack(padx = 8, pady = 8)
root.mainloop()
--- snip ---
The above example allows to create several Directory dialogs.
On the other hand, if I start the Directory dialog from the root
window (from the Tix.Tk() instance), everything works fine. The following
example works:
--- snip ---
import Tix
from Tkconstants import *
from tkFileDialog import Directory
def pick_dir():
dir_dlg= Directory()
dir= dir_dlg.show()
print dir
if __name__ == '__main__':
root = Tix.Tk()
root.title("File Search Demo")
pickButton = Tix.Button(root, text = 'Choose Directory',
command = pick_dir)
pickButton.pack(side = 'bottom')
root.mainloop()
--- snip ---
Would be nice if someone could help me with the first example...
Kind regards,
Karsten.
