python - 如何用导航栏安排框架的布局

Question

我想要的很简单，但却让我发疯。出于某种原因，我无法为未附加到导航工具栏的按钮和树结构创建框架。我拥有的是:

我想要的是

这是代码段:

import os, ttk
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg

from matplotlib.figure import Figure
from Tkinter import * 
import Tkinter, tkFileDialog, tkMessageBox
from numpy import arange, sin, pi, genfromtxt 

import sys
if sys.version_info[0] < 3:
   import Tkinter as Tk
else:
    import tkinter as Tk

root = Tk.Tk()
root.wm_title("Particle Counter")
fig= Figure(figsize = (10,7), dpi =100) # window size
fig.suptitle('Nanobiz Particle Counter', fontsize = 14, fontweight = 'bold')

ax1=fig.add_subplot(211) # figure adds this. later figure is added to canvas.
ax1.set_title('0.5u Particle',fontsize = 10)
ax1.set_xlabel('Time',fontsize = 10)
ax1.set_ylabel('Particle Number',fontsize = 10)   
ax1.set_ylim([0,6000])
ax1.xaxis.set_label_coords(1,-0.09)
ax1.plot(array1)

ax2=fig.add_subplot(212)
ax2.set_title('5u Particle',fontsize = 10)
ax2.set_xlabel('Time',fontsize = 10)
ax2.xaxis.set_label_coords(1,-0.09)
ax2.set_ylim([0,6000])
ax2.set_ylabel('Particle Number',fontsize = 10)
ax2.plot(array2)
ax2.grid()

mainFrame = Frame(root)
mainFrame.pack()

canvas = FigureCanvasTkAgg(fig, mainFrame)


#canvas.mpl_connect('key_press_event', on_key_event)

toolbar = NavigationToolbar2TkAgg(canvas, root)
toolbar.update()
toolbar.pack()
canvas.show()
canvas._tkcanvas.pack(side=Tk.LEFT, fill=Tk.BOTH, expand=1)
canvas.get_tk_widget().pack(side=Tk.LEFT, fill=Tk.BOTH, expand=1)

menu = Menu(root)
root.config(menu=menu)
aboutMenu = Menu(menu)
menu.add_cascade(label="About",menu=aboutMenu, command = about_)
#aboutMenu.pack(side=Tk.RIGHT)


buttonFrame = Frame(root)
buttonFrame.pack(side = Tk.BOTTOM)


closeButton = Tk.Button(buttonFrame, text='Close', width = 6, command=_quit)
closeButton.pack(side= RIGHT)

谢谢

Answer 1

您在 mainFrame 中有 canvas 但您将 NavigationToolbar 添加到 root

使用mainFrame代替

中的 root

toolbar = NavigationToolbar2TkAgg(canvas, mainFrame)

然后您会在 NavigationToolbar

下方看到按钮 Close

要在 canvas 上方获取 NavigationToolbar，请使用

toolbar.pack(side=Tk.TOP)

编辑:至于树 - 你需要在 NavigationToolbar 和 buttonFrame 的左侧或 NavigationToolbar 下方吗及以上 buttonFrame ?

至于我 - 使用 .grid(row=...,column=...) 然后使用 .pack() 更容易
