问题
I'm having a problem with typing into my Tkinter entry. I did a registration code and with every entry on my code calls a virtual keyboard, the virtual keyboard is separated python program. I successfully called another python program but I can't type on my Tkinter entry which is my main program using the virtual keyboard I called. Is there any way to get this done? here is my code
def register(self):
self.master_register = Toplevel()
self.first_name = StringVar()
self.middle_name = StringVar()
self.last_name = StringVar()
self.sex = StringVar()
self.birth_day = StringVar()
self.civil_status = StringVar()
self.label_head = Label(self.master_register, text = "Please fill up all informations below")
self.label_head.pack()
self.label_first_name = Label(self.master_register, text = "First Name")
self.label_first_name.pack()
self.entry_first_name = Entry(self.master_register, textvariable = self.first_name)
self.entry_first_name.pack()
self.entry_first_name.bind('<ButtonPress-1>',self.keyboard)
self.label_middle_name = Label(self.master_register, text = "Middle Name")
self.label_middle_name.pack()
self.entry_middle_name = Entry(self.master_register, textvariable = self.middle_name)
self.entry_middle_name.pack()
self.entry_middle_name.bind('<ButtonPress-1>',self.keyboard)
self.label_last_name = Label(self.master_register, text = "Last Name")
self.label_last_name.pack()
self.entry_last_name = Entry(self.master_register, textvariable = self.last_name)
self.entry_last_name.pack()
self.entry_last_name.bind('<ButtonPress-1>',self.keyboard)
self.label_sex = Label(self.master_register, text = "Sex")
self.label_sex.pack()

self.radio_button_sex1.pack()
self.radio_button_sex2 = Radiobutton(self.master_register, text = "Female", variable = self.sex, value = "Female")
self.radio_button_sex2.pack()
self.label_birthday = Label(self.master_register, text = "Birth Day")
self.label_birthday.pack()
self.entry_birthday = Entry(self.master_register, textvariable = self.birth_day)
self.entry_birthday.pack()
self.entry_birthday.bind('<ButtonPress-1>',self.keyboard)

here is my keyboardclass.py

keyboard.py
I put code in function create() which gets root and entry as arguments - so now I can use import keyboard it other file and run keyboard.create(root, some_entry).
It uses root to create window Toplevel() instead of Tk() - and without second mainloop().
It uses entry to use it in select(entry, value) which will use entry.insert(...)
There is code in if __name__ == "__main__": so you can run it as standalone program to test keyboard.
It displays two Entry and one Text (in which you can test key Enter).
I added code for Enter, Tab, Backspace for Text (which needs different method). When you press Shift or Caps Lock then it starts to insert uppercase chars - but it doesn't change text on buttons in window.
In alphabets I grouped rows in lists so I don't need if/else to check if char should be in next row - I can use two for-loops.
import tkinter as tk
alphabets = [
['`','1','2','3','4','5','6','7','8','9','0','-','=','Backspace'],
['Tab','q','w','e','r','t','y','u','i','o','p','[',']',"\\"],
['Caps Lock','a','s','d','f','g','h','j','k','l',';',"'",'Enter'],
['Shift','z','x','c','v','b','n','m',',','.','/','Shift'],
['Space']
]
uppercase = False # use uppercase chars.
def select(entry, value):
global uppercase
if value == "Space":
value = ' '
elif value == 'Enter':
value = '\n'
elif value == 'Tab':
value = '\t'
if value == "Backspace":
if isinstance(entry, tk.Entry):
entry.delete(len(entry.get())-1, 'end')
#elif isinstance(entry, tk.Text):
else: # tk.Text
entry.delete('end - 2c', 'end')
elif value in ('Caps Lock', 'Shift'):
uppercase = not uppercase # change True to False, or False to True
else:
if uppercase:
value = value.upper()
entry.insert('end', value)
def create(root, entry):
window = tk.Toplevel(root)
window.configure(background="cornflowerblue")
window.wm_attributes("-alpha", 0.7)
for y, row in enumerate(alphabets):
x = 0
#for x, text in enumerate(row):
for text in row:
if text in ('Enter', 'Shift'):
width = 15
columnspan = 2
elif text == 'Space':
width = 130
columnspan = 16
else:
width = 5
columnspan = 1
tk.Button(window, text=text, width=width,
command=lambda value=text: select(entry, value),
padx=3, pady=3, bd=12, bg="black", fg="white"
).grid(row=y, column=x, columnspan=columnspan)
x += columnspan
# --- main ---
if __name__ == '__main__':
root = tk.Tk()
root.title('Test Keyboard')
label = tk.Label(root, text='Test Keyboard')
label.grid(row=0, column=0, columnspan=2)
entry1 = tk.Entry(root)

main.py
It imports keyboard and uses keyboard.create(...) to show keyboard and assing it to selected Entry or Text.
import tkinter as tk
import keyboard
# --- main ---
if __name__ == '__main__':
root = tk.Tk()
root.title('Hello World!')
label = tk.Label(root, text='Form')
label.grid(row=0, column=0, columnspan=3)
#-----
label1 = tk.Label(root, text='Entry 1')
label1.grid(row=1, column=0)
entry1 = tk.Entry(root)
entry1.grid(row=1, column=1, sticky='news')
button1 = tk.Button(root, text='Keyboard', command=lambda:keyboard.create(root, entry1))
button1.grid(row=1, column=2, sticky='news')
#-----
label2 = tk.Label(root, text='Entry 2')
label2.grid(row=2, column=0)
entry2 = tk.Entry(root)
entry2.grid(row=2, column=1, sticky='news')
button2 = tk.Button(root, text='Keyboard', command=lambda:keyboard.create(root, entry2))
button2.grid(row=2, column=2, sticky='news')
#-----
label3 = tk.Label(root, text='Text 1')
label3.grid(row=3, column=0)
text1 = tk.Text(root)
text1.grid(row=3, column=1, sticky='news')
button3 = tk.Button(root, text='Keyboard', command=lambda:keyboard.create(root, text1))
button3.grid(row=3, column=2, sticky='news')
root.mainloop()
I was thinking to create widget which has Entry + Button Keyboard because you use this combination very often. Maybe I create it later.
