Thanks! I was looking the code dialog.tcl and normally it should work since
there is a "transient" command.
I don't understand why it doesn't work.
I've noticed that some times the transient() doesn't work if it is not placed
very close the creation of the Toplevel.
Anyhow I decide to replicate the dialog with python and here is the result if
it can be useful for anyone.
The only thing I didn't manage to make it work properly is the option_add()
Also I've noticed that the "grid_anchor()" which is supposed to be present from
tk 8.5 it is not accepted
as a python command, so I am calling it from tk.
class Dialog(Toplevel):
def __init__(self, master=None, cnf={}, **kw):
Toplevel.__init__(self, master, class_="Dialog", **kw)
self.transient(master)
self.title(cnf["title"])
self.iconname("Dialog")
self.protocol("WM_DELETE_WINDOW", self.close)
self.num = cnf["default"]
cnf = _cnfmerge((cnf, kw))
# Fill the top part with bitmap and message (use the option
# database for -wraplength and -font so that they can be
# overridden by the caller).
#self.option_add("*Dialog.msg.wrapLength","3i","widgetDefault")
#self.option_add("*Dialog.msg.font","TkCaptionFont","widgetDefault")
fbot = Frame(self, relief=RAISED, bd=1)
ftop = Frame(self, relief=RAISED, bd=1)
fbot.pack(side=BOTTOM, fill=BOTH)
ftop.pack(side=TOP, fill=BOTH, expand=YES)
self.tk.call("grid", "anchor", fbot._w, CENTER)
#self.grid_anchor(CENTER)
l = Label(ftop, text=cnf["text"], wraplength="3i",
font="TkCaptionFont", justify=LEFT)
l.pack(side=RIGHT, fill=BOTH, expand=YES, padx="3m", pady="3m")
if cnf["bitmap"]:
l = Label(ftop, bitmap=cnf["bitmap"])
l.pack(side=LEFT, padx="3m", pady="3m")
# Create a row of buttons at the bottom of the dialog
for i,s in enumerate(cnf["strings"]):
b = Button(fbot, text=s, command=lambda
s=self,n=i:s.close(n))
b.bind("<Return>", lambda e : e.widget.invoke())
if i==cnf["default"]:
b.config(default="active")
b.focus_set()
else:
b.config(default="normal")
b.grid(column=i, row=0, sticky=EW, padx=10, pady=4)
self.bind("<Escape>", lambda e,s=self:s.close())
self.bind("<Right>", lambda e :
e.widget.event_generate("<Tab>"))
self.bind("<Left>", lambda e :
e.widget.event_generate("<Shift-Tab>"))
self.deiconify()
self.wait_visibility()
self.grab_set()
self.focus_set()
self.wait_window()

self.num = num

unfortunately this geometry is hard-coded into Tk, so the answer is "no".
You might want to try the tkSimpleDialog.Dialog class instead, by default
these dialogs are placed somewhere into the upper left corner of the
parent, however you would have to set up a messagebox-like dialog
yourself, there is no convenience function for message boxes included.
If using pmw is an option for you, you might also try the Pmw.Dialog ,
iirc there's an option to center the dialog onto its parent.
Regards
Michael
