Hi Russell,
This may be quite different but if I understand the requirements, you can try this:
from Tkinter import *
import tkFileDialog
import tkFileDialog
class app:
def __init__(self, master):
master.title('Hello')
Button(master, text='Button').pack()
tkFileDialog.askopenfilename()
if __name__ == '__main__':
root = Tk()
app = app(root)
root.mainloop()
def __init__(self, master):
master.title('Hello')
Button(master, text='Button').pack()
tkFileDialog.askopenfilename()
if __name__ == '__main__':
root = Tk()
app = app(root)
root.mainloop()

I am trying to write a Tkinter application that will automatically display a
particular dialog box on top of the application when it is initialized.
(Like a word processor opening a "File Open" dialog as the first thing that
happens when you enter the application.) How do I do this? I have a method
that invokes the dialog box, but I cannot call it until after my app's
mainloop has started; but once the mainloop has started, I can't call it
from the program, either!
I'm sure I'm overlooking something obvious here.
Example (skeleton) code:
from Tkinter import *
class NewPageDialog(tkSimpleDialog.Dialog):
def body(self, master, title="Select Target"):
Label(master, text="Target page:").grid(row=0)
self.targetpage = Entry(master)
self.targetpage.grid(row=0, column=1)
return self.targetpage
def validate(self):
return True
def apply(self):
pass
class GuiApplication(Frame):
def __init__(self, master):
Frame.__init__(self, master)
def newpage(self):
n = NewPageDialog(self)
self.targetpage = n.targetpage.get()
if __name__ == "__main__":
app = GuiApplication(Tk())
# do something here to cause GuiApplication to invoke newpage() method
when it starts
app.mainloop()

You might try writing
app.after_idle(app.newpage)
or simply:
app = GuiApplication(Tk())
app.newpage()
app.mainloop()
except that this will always enter main! loop after newpage is called,
which may not be what you desire.
