Dear all,
I have a Tkinter application which is then packaged into an App
using py2app.
I (and various others) have a problem that Windows don't lift
to visibility under MacOSX Lion, at least using Python 2.7.2, Tk8.5
Lion 10.7.4 and py2app 2.6.4 IF argv_emulation is set to True
This can be demonstatrated by the following scripts:
File 1: test.py
---------------------
from Tkinter import *
tk = Tk()
fr=Frame(tk, height=400, width=400)
fr.pack()
def openWin():
t=Toplevel(tk)
Button(t, text="Close", command=lambda w=t: w.destroy()).pack()
for i in range(4):
for j in range(4):
Button(fr, text="Open", command=openWin).grid(row=i, column=j)
tk.mainloop()
--------------------
File 2: PackageMaker.py
---------------------
rom setuptools import setup
import sys
sys.argv=[sys.argv[0]]
sys.argv.append("py2app")
setup(
app=['test.py'],
data_files=[],
options={'py2app': {'argv_emulation': True, 'resources': []}},
setup_requires=['py2app'],
)
--------------------
Now, the test.py script works fine when executed from Idle
or using pythonw. It just doesn't work as expected when
packaged as an executable by py2app. Windows do not appear
when the buttons are pressed.
(but note: the application does work when run from a console using:
test.app/Contents/MacOS/test )
Kevin Walzer verified the behaviour I report on his machine.
He found that if you set argv_emulation to False, the program
worked as expected.
NOW, I need argv_emulation, since a user might open my application by
double clicking on a document associated with my program. I don't want to
lose
this functionality (which users are used to by now) just because of a bug.
Now, I find it atrange that a bit of code which deals with passing
command line args to the program should mess up Tkinter's
windowing, just doesn't make sense.
Anybody know of a workaround? Or is this a true bug that
can be fixed?
