Tkinter double tk.文本不会使用相同的滚动条滚动

Question

我希望滚动条同时滚动tk.Text。我尝试了很多东西，比如tk.Scrollbar:(command=self.multiple_scroll)的函数和当前配置：

self.reader = tk.Toplevel(self)
self.reader.title("XXX")
self.reader.resizable(False, True)
self.reader.geometry("650x500")
self.reader.minsize(650,150)

self.panel = tk.Text(self.reader, wrap="word", width=12, font=('Courier',14))
self.viewer = tk.Text(self.reader, wrap="word", font=('Courier',14))
self.scrollbar = tk.Scrollbar(self.reader, command=(self.panel.yview, self.viewer.yview))

self.panel.configure(yscrollcommand=self.scrollbar.set)
self.viewer.configure(yscrollcommand=self.scrollbar.set)

self.scrollbar.pack(side="right", fill="y")
self.panel.pack(side="left", fill="both", expand=True)
self.viewer.pack(side="bottom", fill="both", expand=True)

当我使用滚轮滚动时，光标下的文本会移动，但另一个文本不会移动。我需要将这两个tk.Text分开

Answer 1

从这里复制：Python tkinter, Making two text widget's scrolling synchronize当然，从这里更重要的：Multiple commands to a button in tkinter这表示：

To do "two things with one button", the correct solution is to create a function that does these "two things", and then associate that function with the button.

我的结局是：

将tkinter作为tk导入

class MainApplication(tk.Frame):
    def __init__(self, parent, *args, **kwargs):
        tk.Frame.__init__(self, parent, *args, **kwargs)
        self.reader= parent
        
        # self.reader = tk.Toplevel(self)
        self.reader.title("XXX")
        self.reader.resizable(False, True)
        self.reader.geometry("650x50")
        self.reader.minsize(650,150)
        
        self.panel = tk.Text(self.reader, wrap="word", width=12, font=('Courier',14))
        self.viewer = tk.Text(self.reader, wrap="word", font=('Courier',14))
        # self.scrollbar = tk.Scrollbar(self.reader, command=(self.panel.yview, self.viewer.yview))
        
        self.scrollbar = tk.Scrollbar(self.reader, command=(self.on_scrollbar))
        
        #self.panel.configure(yscrollcommand=self.scrollbar.set)
        #self.viewer.configure(yscrollcommand=self.scrollbar.set)
        
        self.scrollbar.pack(side="right", fill="y")
        self.panel.pack(side="left", fill="both", expand=True)
        self.viewer.pack(side="bottom", fill="both", expand=True)
        
        
        
        # Changing the settings to make the scrolling work
        # self.scrollbar['command'] = self.on_scrollbar
        self.panel['yscrollcommand'] = self.on_textscroll
        self.viewer['yscrollcommand'] = self.on_textscroll
        
        
    def on_scrollbar(self, *args):
        """
        Scrolls both text widgets when the scrollbar is moved
        """
        self.panel.yview(*args)
        self.viewer.yview(*args)
            
    def on_textscroll(self, *args):
        '''Moves the scrollbar and scrolls text widgets when the mousewheel
        is moved on a text widget'''
        self.scrollbar.set(*args)
        self.on_scrollbar('moveto', args[0])



if __name__ == "__main__":
    master = tk.Tk()
   
    MainApplication(master)  
    master.mainloop()  

让我们知道它是否如预期的那样工作，我注意到的是，一旦两个文本中的一个到达末尾，另一个文本将继续在小于最长文本的窗口中使两个文本不对齐。不知道如何处理，需要找到一种方法添加空行，使两个文本具有相同的长度，让我知道是否有更好的方法
