I'm using Toplevel
to produce two windows. But when it opens the second window, the keyboard is not activated instantly (both windows are opened at the same time), I need to click the second window first in order to use the keyboard. I tried to use root.lift
to fix it, but it doesn't work. What is the problem here?
My codes:
class practisePage1():
def __init__(self, master):
self.master = master
self.master.update_idletasks()
self.master.attributes('-fullscreen', True)
self.button1 = Button(self.master, text="NEXT", bg='gray77', command=self.gotoPage3, anchor=CENTER)
self.button1.pack()
def gotoPage1(self):
self.root1 = Toplevel(self.master)
self.instPage1 = practisePage1(self.root1)
class practisePage1():
def __init__(self, master):
self.master = master
self.master.update_idletasks()
self.master.attributes('-fullscreen', True)
self.choiceA = master.bind('a', self.showResultEx1) #can't be used directly, the window needs to be clicked first
self.choiceB = master.bind('l', self.showResultEx2) #can't be used directly.
def showResultEx1(self):
#some codes
def showResultEx2(self):
#some codes
Thanks for your help!
It is keyboard focus problem. I add focus_set()
before I bind my keyboard, it solves the problem.
