[Tkinter-discuss] Keeping keyboard focus when window iconified (Win XP) ?

[francois schnell]

Hello,

I'm doing a small program to capture screenshots.

But obviously I don't wan my GUI to be visible during the sreenshots and I
want to continue to take sreenshots (with my key binding) even when the
program doesn't have the main focus anymore.

I'm running Python 2.4 on Win XP Family.

Do you have an idea how I could do this ?

Thanks in advance

francois

fen1.title("Screenshots Tests")
bu11=Button(fen1, text='screenshot')
fen1.bind("s",screenshot)
#fen1.bind_all("s",screenshot)
bu11.bind("<Button-1>",screenshot)
buQuit=Button(fen1, width= 20, text='Quitter',command=exitapp)
bu12=Button(fen1, text='invisible', command=invisible)

bu11.pack()
bu12.pack()
buQuit.pack()

fen1.mainloop()
