Question

（tkinter）我想在调整大小后立即捕获窗口的宽度和高度。我该怎么做，是否存在任何方法？

已编辑的问题：

定义，它不是重复项。因为in the link有画布，而且这种方法

self.scale("all",0,0,wscale,hscale)

不适用于相框。我仍然不知道如何调整框架的大小，因此在调整框架大小后，它的宽度和高度将与窗口相同。（就像在photoshop中一样，我调整窗口的大小，背景正在更改大小。）

布莱恩，我尝试按照您说的那样调整大小，但没有用。我用“ !!!”标记了尝试这样做的地方评论。我的代码：

    from tkinter import *
import ctypes


class Main(Frame):
    def __init__(self, main):
        Frame.__init__(self, main)
        # Vars that will be defined by user:
        self.canvas_width = 600
        self.canvas_height = 600

        self.frame_width = 750
        self.frame_height = 600

        # Flexible widgets when window size alters:
        main.columnconfigure(0, weight=1)
        main.rowconfigure(0, weight=1)


        # Canvas and frame
        self.canvas_frame = Frame(main, width=self.frame_width, height=self.frame_height, relief='groove')
        self.canvas_frame.grid(row=1, column=1)
        self.canvas_frame.grid_propagate(False)
        self.canvas = Canvas(self.canvas_frame, width = self.canvas_width, height = self.canvas_height,
                        bg='bisque')
        self.canvas.grid(row=0, column=0)

        # Right click menu
        self.rmenu = Menu(self.canvas_frame, tearoff=0, takefocus=0)
        self.rmenu.add_command(label='Add', command=self.hello)
        self.canvas.bind("<ButtonPress-3>", self.popup)

        # Bind
        self.canvas.bind("<ButtonPress-1>", self.scroll_start)
        self.canvas.bind("<B1-Motion>", self.scroll_move)

        self.canvas_frame.bind("<Configure>", self.on_resize) # !!!!



    # resizing window:
    def on_resize(self, event): # !!!!
        # determine the ratio of old width/height to new width/height
        self.canvas_frame.width = event.width
        self.canvas_frame.height = event.height
        # resize the canvas
        self.canvas_frame.config(width=self.canvas_frame.width, height=self.canvas_frame.height)
        print(self.canvas_frame.width)  # return the same height and width
        print(self.canvas_frame.height) # after resizing

if __name__ == '__main__':
    main = Tk()
    Main(main)
    main.mainloop()
