Python 如何配置MatPlotLib工具栏,使工具栏中的按钮是ttk按钮而不是旧的Tk按钮

Python 如何配置MatPlotLib工具栏,使工具栏中的按钮是ttk按钮而不是旧的Tk按钮,python,windows,matplotlib,tkinter,Python,Windows,Matplotlib,Tkinter,我一直在考虑在tkinter GUI应用程序中嵌入matplotlib图,但在使用工具栏时,我不喜欢它的外观。有人能告诉我如何制作自己的按钮,制作ttk按钮,并将它们放入工具栏吗?您可以覆盖导航工具栏2TK中的方法,并为图标提供自己的图像,如下所示: from tkinter import * from matplotlib.backends.backend_tkagg import NavigationToolbar2Tk, FigureCanvasTkAgg from matplotlib.

我一直在考虑在tkinter GUI应用程序中嵌入matplotlib图,但在使用工具栏时,我不喜欢它的外观。有人能告诉我如何制作自己的按钮,制作ttk按钮,并将它们放入工具栏吗?

您可以覆盖
导航工具栏2TK
中的方法,并为图标提供自己的图像,如下所示:

from tkinter import *
from matplotlib.backends.backend_tkagg import NavigationToolbar2Tk, FigureCanvasTkAgg
from matplotlib.figure import Figure
from matplotlib.backends._backend_tk import ToolTip

root = Tk()

class Navigator(NavigationToolbar2Tk):
    """
    Customized Navigator object
    - Removed mouse_move event.x and event.y display
    - Changed buttons layout
    """
    def mouse_move(self,event):
        pass

    def _Button(self, text, file, command, extension='.gif'):
        im = PhotoImage(master=self, file=file)
        b = Button(master=self, text=text, padx=2,image=im, command=command,bg="DeepSkyBlue4",relief="flat")
        b._ntimage = im
        b.pack(side=LEFT)
        self.tool_buttons.append(b)
        return b

    def _init_toolbar(self):
        self.tool_buttons = []
        self.toolbar_icons = ["icons/home.png", #provide paths of your own icons
                              "icons/backward.png",
                              "icons/forward.png",
                              None,
                              "icons/pan.png",
                              "icons/zoom.png",
                              "icons/config.png",
                              None,
                              "icons/save.png"]
        xmin, xmax = self.canvas.figure.bbox.intervalx
        height, width = 50, xmax-xmin
        Frame.__init__(self, master=self.window,
                          width=500, height=int(height))
        self.update()
        num = 0
        for text, tooltip_text, image_file, callback in self.toolitems:
            if text is None:
                self._Spacer()
            else:
                try:
                    button = self._Button(text=text, file=self.toolbar_icons[num],
                                          command=getattr(self, callback))
                    if tooltip_text is not None:
                        ToolTip.createToolTip(button, tooltip_text)
                except IndexError:
                    pass
            num+=1
        self.pack(side=BOTTOM, fill=X)

    def destroy(self, *args):
        Frame.destroy(self)


f = Figure()

canvas = FigureCanvasTkAgg(f, root)
canvas.get_tk_widget().pack(fill=BOTH, expand=True)

toolbar = NavigationToolbar2Tk(canvas, root)

custom_toolbar  = Navigator(canvas, root)
custom_toolbar.config(background="DeepSkyBlue4")
root.mainloop()
结果(顶部为自定义工具栏,底部为原始工具栏):


我曾经创建了
导航工具栏2TK
的子类,然后逐个修改相关的方法/参数。但是很痛,你会怎么做?我对如何更改按钮的参数感到困惑,因为工具栏是在matplotlib模块中硬编码的,这正是您需要将其子类化的原因——覆盖您需要修改的部分。我给你一个小样品。
