inject screen setup when user is using turtle to put window in better spot

[Almenon]

Currently the window pops up right in your face and is very annoying.

By injecting screen setup code I could put the window in a better spot.

check to make sure they are not already using turtle.setup() beforehand.

Please comment or +1 if you like this feature

matplotlib:

f.canvas.manager.window.wm_geometry("+1200+0") #right-hand side

turtle:

turtle.setup(500,500,-1,0) # top right-hand side

from tkinter import Tk, Label
root = Tk()

root.lower() # prevent screen from appearing on top

to_read = "Stuff" 
w = Label(root, text=to_read)
w.pack()
root.mainloop()

annoying thing is despite appearing in back it still steals focus from main app....

Also turtle doesn't steal focus when in cmd or repl, only when executing file or in arepl - why is that? :/

[Almenon]

oh i see - arepl is run as a file (python pythonEvaluator.py) so that's why it steals focus like running a python file. Maybe there is some launch option for not stealing focus?

alt_key = 0x12

def steal_focus():
    #keybd_event(alt_key, 0, extended_key | 0, 0)
    keybd_event(alt_key, 0, 0, 0)

from tkinter import Tk, Label
root = Tk()

# can i call this when i gain focus somehow?
root.after(250, steal_focus)

# none of below crap worked
#root.lower() # prevent screen from appearing on top
#x=root.tk_focusPrev() 
#root.focusmodel("passive")
#root.protocol("WM_TAKE_FOCUS", lambda x:print('focus'))

to_read = "Stuff" 
w = Label(root, text=to_read)
w.pack()
#x=w.tk_focusPrev()
#x=w.focus
#x=w.grab_release()
root.mainloop()

....... so hacky. Was fun to make tho

[Almenon]

should ask tkinter community / python chat why tkinter takes focus when launching from a file and how to prevent that.

[Almenon]

I don't know why I spent so much time on this I forgot this problem was already fixed for turtle with #202 - if python doesn't restart each time then python doesn't steal focus.

Which by the way doesn't make any sense! The first run of arepl is the same restart or not...... :(
