Tkinter OSX and "lift"

[Miki]

Hello,

Tk.lift doesn't seem to work on OSX (Python 2.5.1).
The below starts OK, but the window is the behind all other windows.

from Tkinter import *

root = Tk()
Button(root, text="OK", command=root.quit).pack()
root.lift()
root.mainloop()

Any ideas how to tell the window to start as the topmost window?

Thanks,

If you click on the PythonLauncher application that runs in your dock
when this script is executed, the window comes into focus fine.

You're right, but I want to window to be initially in focus (without
the user clicking on the python launcher icon).

All the best,

"Lift" (which calls the Tk command "raise") doesn't work this way, at
least not under Aqua. If your application has focus, "lift" will raise
the widget being called to the top of the stacking order. However, it
will not make the application frontmost. To do this you'd have to use
Carbon calls (look at Carbon.CarbonEvt) or use a Tk extension and call
it from Python. Of course, this is pretty much a non-issue if your
application is wrapped as a standard Mac application bundle via
py2app--most Mac users don't run Python apps from the Terminal but
instead double-click an application icon. In that event, "lift" should
work fine, because the application will already have focus.

There is a trick that sometimes works even for interpreted application:

import Tkinter as tk
root =3D tk.Tk()
root.withdraw()
# Code building the window...
root.lift()
root.deiconify()
root.mainloop()

This sometimes forces the window to be top-most. If this doesn't work, y=

can also try:

import Tkinter as tk
root =3D tk.Tk()
root.withdraw()
# Code building the window...
root.lift()
root.after_idle(root.deiconify)
root.mainloop()

This was a trick that had to be done on Windows a few years back to forc=

if this will work the same, though...

Sadly, both of them didn't work.
