如何从NavigationToolbar2Tk/图中删除工具栏按钮
如何从NavigationToolbar2Tk/图中删除工具栏按钮
提问于 2019-12-03 11:16:28
我使用matplotlib和tk/tkinter，下面是"嵌入传统知识“
self._figure = Figure()
self._axes: matplotlib.axes.Axes = self._figure.add_subplot(111)
self._canvas = FigureCanvasTkAgg(self._figure, master=frame)
toolbar = NavigationToolbar2Tk(self._canvas, frame)
toolbar.update()根据刀具管理器
self._figure.canvas.manager.toolmanager.remove_tool("pan")应该有用，但它不起作用。
# self._figure.canvas does not have attribute 'manager'从vs代码截图中可以看出，FigureCanvasTkAgg没有属性'manager'：

Canvas和NavigationToolbar2Tk嵌入在tkinter中似乎具有不同的结构和不同的功能。标准matplotlib窗口使用Qt作为后端。
toolbar = NavigationToolbar2Tk(self._canvas, frame)列出有关按钮的信息
print(toolbar.toolitems) 移除Pan按钮-这是第四个按钮
toolbar.children['!button4'].pack_forget()将新功能分配给现有按钮--即。Home
def my_function():
print("Pressed Home")
toolbar.children['!button1'].config(command=my_function)添加新按钮
button = tkinter.Button(master=toolbar, text="Quit", command=_quit)
#button.pack()
button.pack(side="left")与添加其他tkinter小部件的方式相同-- Label、Entry等。
编辑：，正如ImportanceOfBeingErnest在评论中提到的，它可以做得更优雅。
NavigationToolbar2Tk.toolitems = [t for t in NavigationToolbar2Tk.toolitems if
t[0] not in ('Pan',)]全工作实例
