Hi there
ui updates with tkinter will only happen IMHO after your method returns.
use the widget.after() method (check
http://infohost.nmt.edu/tcc/help/pubs/tkinter/universal.html). Something
like this:
def screenshot(event):
fen1.iconify()
fen1.after(200,doscreen)
i=0
def doscreen():
global i
print " screen !"
i= i+1
name = "session1picture"
name= name + str(i)
print name
myscreen= ImageGrab.grab()
myscreen.show()
myscreen.save("C:/"+name+ '.jpeg')
fen1.deiconify()
If you want ro remove the taskbar entry you can apply the win32 style
MYWS_EX_NOACTIVATE (at least with win2000 or later). This requires C
programming, and is just the first thing that came into my mind.
