在 tkinter 中显示 shapefile？

Question

我希望代码中下面提到的“shapefile”显示在 tkinter 窗口的“sideFrame”内。但是现在，shapefile 正在另一个我不想打开的窗口中打开。也就是说，我想在“tkinter”窗口的右框架内显示“shapefile”。我是这个领域的新手，所以可以通过代码解释清楚。

import matplotlib
import matplotlib.pyplot as plt
matplotlib.use("TkAgg") # for backend
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
from matplotlib.figure import Figure

def forSubmit():
    if MyVar1.get()== 0 or MyVar2.get()==0:
        messagebox.showwarning("Warning", "Select input files!")
    fp = r"F:\ISRO\Spatial_Data\grid_jagalur_spatialjoin.shp"
    data = gpd.read_file(fp)
    print (type(data))
    data.head()
    data.plot()
    plt.show(sideFrame)                                                                         

middleFrame = LabelFrame(root,width=800,text="Input data")
middleFrame.grid(row=1, column=0, padx=8, pady=8, sticky=N+S+W+E)
middleFrame.grid_rowconfigure(0, weight=1)
middleFrame.grid_rowconfigure(1, weight=0)
middleFrame.grid_columnconfigure(0, weight=1)
middleFrame.grid_columnconfigure(1, weight=1)      

Button6 = Button(middleFrame, text="View", command=forSubmit)
Button6.grid(row=1, column=1, padx=4, pady=4,sticky=E) 

sideFrame = LabelFrame(root,width=500, bg="powder blue", text="Image")
sideFrame.grid(row=0, column=1, padx=8, pady=8, sticky=N+S+W+E, rowspan=3)
sideFrame.grid_rowconfigure(0, weight=1)
sideFrame.grid_rowconfigure(1, weight=1)
sideFrame.grid_rowconfigure(2, weight=1)
sideFrame.grid_columnconfigure(0, weight=1)
sideFrame.grid_columnconfigure(1, weight=1)

Answer 1

您应该将一个 FigureCanvasTkAgg 小部件添加到您的 sideFrame 中，然后尝试以下几行：

fig, ax = plt.subplots(nrows = 1, ncols = 1)
cavnas_plot = FigureCanvasTkAgg(fig, master = sideFrame)
canvas_plot.draw()
canvas_plot.get_tk_widget.grid(row = 0, column = 0)

确保有足够的空间让 sideFrame 在主窗口中可见
