使用按钮输入tkinter条目

问题描述

我正在开发一个小程序，但我遇到了一个问题，我想在tkinter窗口中创建类似键盘的内容。

窗口模板的代码如下：

main_screen = Tk()
main_screen.title("keyboard")
main_screen.geometry("200x200")

Btn_1 = Button(main_screen,text="á")
Btn_1.place(x=90,y=100,anchor='center')
Btn_2 = Button(main_screen,text="ñ")
Btn_2.place(x=110,anchor='center')
Btn_3 = Button(main_screen,text="í")
Btn_3.place(x=130,anchor='center')  
Btn_4 = Button(main_screen,text="ú")
Btn_4.place(x=70,anchor='center')  

entry_1 = Entry(main_screen)
entry_1.place(x=100,y=130,anchor='center')

entry_2 = Entry(main_screen)
entry_2.place(x=100,y=150,anchor='center')



main_screen.mainloop()

我要实现的目的是使程序在输入_1或输入_2的位置键入所选的字母（取决于当前单击的带有闪烁指示器的字母），基于我按下的按钮，因为我没有按钮，我既不想更改语言，也不想使用Alt +符号组合。

我找不到任何可以帮助我获得这种结果的东西，我将不胜感激任何提示

如果我不清楚任何事情，请告诉我。预先感谢。

解决方法

给您的答案很简单。下面的代码：

对于entry_name = Entry(main_screen) entry_name.pack() button_name = Button(main_screen,text="character_here",command = lambda x: insert("same character given in text option") button_name.pack() 函数，请提供如下代码：

insert()

,

首先，您需要通过在选择条目时设置变量来知道选择了哪个条目。

第二个创建单击按钮时调用的函数。在函数内部，将相应的字符插入所选的条目。

以下是根据您的代码修改的示例：

from tkinter import *

current_entry = None # hold the reference to the selected entry

def on_focus_in(event):
    global current_entry
    current_entry = event.widget # save the selected entry

def on_focus_out(event):
    global current_entry
    current_entry = None

def send_key(key):
    if current_entry:
        current_entry.insert('insert',key) # insert the key to the selected entry

main_screen = Tk()
main_screen.title("keyboard")
main_screen.geometry("200x200")

Btn_1 = Button(main_screen,text="á",command=lambda:send_key("á"))
Btn_1.place(x=90,y=100,anchor='center')
Btn_2 = Button(main_screen,text="ñ",command=lambda:send_key("ñ"))
Btn_2.place(x=110,anchor='center')
Btn_3 = Button(main_screen,text="í",command=lambda:send_key("í"))
Btn_3.place(x=130,anchor='center')  
Btn_4 = Button(main_screen,text="ú",command=lambda:send_key("ú"))
Btn_4.place(x=70,anchor='center')  

entry_1 = Entry(main_screen)
entry_1.place(x=100,y=130,anchor='center')
entry_1.bind('<FocusIn>',on_focus_in)
entry_1.bind('<FocusOut>',on_focus_out)

entry_2 = Entry(main_screen)
entry_2.place(x=100,y=150,anchor='center')
entry_2.bind('<FocusIn>',on_focus_in)
entry_2.bind('<FocusOut>',on_focus_out)

main_screen.mainloop()
