我想制作许多笔记本标签,并希望将它们放在画布中并添加水平滚动条,以便可以滚动它们。 我设置了画布大小,但是当我添加新标签时,画布大小会不断变化。另外,滚动条不起作用,您能告诉我我在做什么错吗?
程序没有显示任何错误。这是代码:
from tkinter import *
from tkinter import ttk
myApp = Tk()
myApp.title(" Program ")
myApp.geometry("900x500")
CanvasTabs = Canvas(myApp, width=50, height=50)
CanvasTabs.grid(row=0,column=0)
tabs = ttk.Notebook(CanvasTabs, width=100, height=100)
tab1 = ttk.Frame(tabs)
tabs.add(tab1,text=" Tab 1 ")
tab2 = ttk.Frame(tabs)
tabs.add(tab2,text=" Tab 2 ")
tab3 = ttk.Frame(tabs)
tabs.add(tab3,text=" Tab 3 ")
tab4 = ttk.Frame(tabs)
tabs.add(tab4,text=" Tab 4 ")
hbar=Scrollbar(CanvasTabs,orient=HORIZONTAL)
hbar.pack(side=TOP,fill=X)
hbar.config(command=CanvasTabs.xview)
CanvasTabs.config(xscrollcommand=hbar.set)
tabs.pack(expand=1, fill="both")
myApp.mainloop()
答案 0 :(得分:2)
答案 1 :(得分:0)
以this post上的布莱恩(Bryan)示例为例,并对其进行修改以包含您的Notebook代码,我们获得了一个功能正常的滚动条,如果滚动条超出了窗口的限制,您可以在该滚动条上滚动。
Bryan的示例使用了pack()
几何管理器,但是我个人认为grid()
更易于可视化,因此在示例中我将包替换为grid()
。
更新:
import tkinter as tk
import tkinter.ttk as ttk
class Example(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
self.canvas = tk.Canvas(self, borderwidth=0)
self.frame = tk.Frame(self.canvas)
self.vsb = tk.Scrollbar(self, orient="horizontal", command=self.canvas.xview)
self.vsb.grid(row=1, column=0, sticky="nsew")
self.canvas.configure(xscrollcommand=self.vsb.set)
self.canvas.grid(row=0, column=0, sticky="nsew")
self.canvas.create_window((3,2), window=self.frame, anchor="nw", tags="self.frame")
self.frame.bind("<Configure>", self.frame_configure)
self.populate()
def populate(self):
tabs = ttk.Notebook(self.frame, width=100, height=100)
for tab in range(50):
tabs.add(ttk.Frame(tabs), text=" Tab {} ".format(tab))
tabs.grid(row=0, column=0, sticky="ew")
def frame_configure(self, event):
self.canvas.configure(scrollregion=self.canvas.bbox("all"))
if __name__ == "__main__":
app = Example()
app.mainloop()
更新结果:
根据您在注释中的请求,这里是一个非OOP示例:
import tkinter as tk
import tkinter.ttk as ttk
root = tk.Tk()
canvas = tk.Canvas(root, borderwidth=0)
frame = tk.Frame(canvas)
vsb = tk.Scrollbar(root, orient="horizontal", command=canvas.xview)
vsb.grid(row=1, column=0, sticky="nsew")
canvas.configure(xscrollcommand=vsb.set)
canvas.grid(row=0, column=0, sticky="nsew")
canvas.create_window((3,2), window=frame, anchor="nw", tags="frame")
tabs = ttk.Notebook(frame, width=100, height=100)
for tab in range(50):
tabs.add(ttk.Frame(tabs), text=" Tab {} ".format(tab))
tabs.grid(row=0, column=0, sticky="ew")
def frame_configure(event):
global canvas
canvas.configure(scrollregion=canvas.bbox("all"))
frame.bind("<Configure>", frame_configure)
root.mainloop()
