Hi,
I searched the web and docs but cannot figure out whats wrong with this
code:
#!/usr/bin/python
import Tkinter as Tk
class testtk(Tk.Frame ):
def __init__(self):
self.root = Tk.Tk()
Tk.Frame.__init __(self,self.ro ot)
self.frame = Tk.Frame(self.r oot)
self.var = Tk.StringVar()
self.var.trace_ variable('w',se lf.check)
Tk.Entry(self.f rame, textvariable = self.var).pack( )
self.frame.pack ()
Tk.mainloop()
def check():
pass
if __name__ == "__main__":
t = testtk()
t.var.set("TEST ")
Result:
Traceback (most recent call last):
File "<stdin>", line 22, in ?
File "/usr/lib/python2.3/lib-tk/Tkinter.py", line 191, in set
return self._tk.global setvar(self._na me, value)
_tkinter.TclErr or: can't set "PY_VAR0": invalid command name
"-1210125972check "
Any ideas, why I cant set the variable var?

Ok. The problem is that the program enters the mainloop on t = testtk()
and t.var.set("TEST ") is executed when the program ends.
But, what I want to do is to let another program create my tkinter GUI
via initiating my class through COM. Then the COM-Client should be able
to set values of the tkinter variables from "the outside".
How to do this?
Do I have to make my GUI program threaded ? like described here: http://aspn.activestate.com/ASPN/Coo...n/Recipe/82965
The mainloop resides in one thread and the other thread provides the COM
object and queues the foreign COM method calls to the GUI thread?
Is there a simpler solution?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
