在另一个 python 程序中使用虚拟键盘输入条目

Question

我在输入 Tkinter 条目时遇到问题。我做了一个注册码，我的代码上的每个条目都调用了一个虚拟键盘，虚拟键盘是独立的 python 程序。我成功调用了另一个 python 程序，但我无法使用我调用的虚拟键盘在我的主程序 Tkinter 条目上键入。 有没有办法做到这一点？ 这是我的代码

    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 = Radiobutton(self.master_register, text = "Male", variable = self.sex, value = "Male" )
    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)

    self.label_civil_status = Label(self.master_register, text = "Civil Status")
    self.label_civil_status.pack()
    self.entry_civil_status = Entry(self.master_register, textvariable = self.civil_status)
    self.entry_civil_status.pack()
    self.entry_civil_status.bind('<ButtonPress-1>',self.keyboard)

    self.button_submit = Button(self.master_register, text = "Submit", command = lambda: self.registered(self.first_name, self.middle_name,
                                                                                        self.last_name, self.sex, self.birth_day,
                                                                                        self.civil_status))
    self.button_submit.pack()

def keyboard(self, event):
    exec(open("keyboardclass.py").read());

这是我的keyboardclass.py

root.mainloop()

Answer 1

keyboard.py

我将代码放在函数 create() 中，该函数将 root 和 entry 作为参数 - 所以现在我可以在其他文件中使用 import keyboard 并运行 keyboard.create(root, some_entry)。

它使用root 来创建窗口Toplevel() 而不是Tk() - 并且没有第二个mainloop()。

它使用entry 在select(entry, value) 中使用它，这将使用entry.insert(...)

if __name__ == "__main__": 中有代码，因此您可以将其作为独立程序运行以测试键盘。

它显示两个Entry 和一个Text（您可以在其中测试密钥Enter）。

我为Enter、Tab、Backspace 为Text 添加了代码（需要不同的方法）。当您按下 Shift 或 Caps Lock 时，它会开始插入大写字符 - 但不会更改窗口中按钮上的文本。

在 alphabets 中，我将行分组到列表中，因此我不需要 if/else 来检查 char 是否应该在下一行 - 我可以使用两个 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)
    entry1.grid(row=1, column=0, sticky='news')

    button3 = tk.Button(root, text='Keyboard', command=lambda:create(root, text1))

    root.mainloop()

ma​​in.py

它导入keyboard 并使用keyboard.create(...) 显示键盘并将其分配给选定的Entry 或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()

我正在考虑创建具有条目 + 按钮 Keyboard 的小部件，因为您经常使用这种组合。也许我稍后会创建它。
