这个想法是让可滚动的画布和其文本小部件在调整大小时能够扩展或填充整个根/顶层。
如果我使用框架,我可以做到这一点,但对于可滚动的框架,您需要创建一个画布小部件并使其可滚动。现在我不知道问题是画布还是画布上插入的小部件?
import tkinter as tk
from tkinter import ttk
class ScrollableFrame():
def __init__(self, container, *args, **kwargs):
self.container = container
self.canvas = tk.Canvas(self.container, bg="green")
self.scrollbar = ttk.Scrollbar(self.container, orient="horizontal", command=self.canvas.xview)
self.scrollable_frame = tk.Frame(self.canvas)
self.scrollable_frame.grid(sticky="wesn")
self.scrollable_frame.bind("<Configure>", lambda e: self.canvas.configure(scrollregion=self.canvas.bbox("all")))
self.canvas.create_window((0, 0), window=self.scrollable_frame, anchor="nw")
self.canvas.configure(xscrollcommand=self.scrollbar.set)
self.canvas.grid(row=0, column=0, sticky="wesn")
self.scrollbar.grid(row=1, column=0, sticky="wesn")
if __name__ == "__main__":
root = tk.Tk()
root.configure(bg="grey20")
s = ScrollableFrame(root)
t = tk.Text(s.scrollable_frame)
t.grid(row=0, column=0, sticky="wesn")
t2 = tk.Text(s.scrollable_frame)
t2.grid(row=0, column=1, sticky="wesn")
root.mainloop()
我很乐意为您提供帮助。
