Hi guys, im having a little problem to make the StringVar Linked to my OnScreen
Keyboard Change when the user click in one Entry.
Here's my code:
from tkinter import *
____________________________Begin Code_______________________________________
def frame(root, side):
w = Frame(root)
w.pack(side=side, expand=YES, fill=BOTH)
return w
def button(root, side, text, command=None):
w = Button(root, text=text, command=command)
w.pack(side=side, expand=YES, fill=BOTH)
return w
class Keyboard(Frame):
def __init__(self):
Frame.__init__(self)
self.option_add('*Font', 'Verdana 12 bold')
self.pack(expand=YES, fill=BOTH)
self.master.title('Simple Screen Keyboard')
def detect_Focus(event):
print ('Change selected_display to the display correspondent to
selected entry')
display_1 = StringVar()
entry_1 = Entry(self, relief=SUNKEN, textvariable=display_1)
entry_1.bind('<FocusIn>', detect_Focus)
entry_1.pack(side=TOP, expand=YES, fill=BOTH)
display_2 = StringVar()
entry_2 = Entry(self, relief=SUNKEN, textvariable=display_2)
entry_2.bind('<FocusIn>', detect_Focus)
entry_2.pack(side=TOP, expand=YES, fill=BOTH)
selected_display = display_1
for key in ("123", "456", "789", "-0."):
keyF = frame(self, TOP)
for char in key:
button(keyF, LEFT, char,
lambda w=selected_display, c=char: w.set(w.get() + c))
if __name__ == '__main__':
Keyboard().mainloop()
____________________________End Code_______________________________________
When i run the detect_Focus Function, i wanted change the selected_display, to
make the user change the entry2(display_2), using my on screen keyboard.
Thanks in advance!
