Tkinter / Python - 在调整窗口大小时禁用按钮大小调整

标签: python user-interface button tkinter grid

我有一个带有列表框的窗口,可以相互调整大小。我为此使用了网格。列表框下方有一排按钮,这些按钮当前正在移动并随窗口一起调整大小。我希望按钮保持原位并保持一致的大小,同时窗口和列表框调整大小(因此按钮始终保留在列表框的左下角)。

有一种简单的方法吗?我今天刚刚开始使用Tkinter,所以我可能在文档中错过了它,或者可能只是对网格布局感到困惑。

按钮设置如下:

nextbutton = Button(self, width = 30, height = 30, image = ffbtn)
nextbutton.image = ffbtn
nextbutton.bind("<Button-1>", self.forward)
nextbutton.grid(row = 10, column=4, sticky='w')

我已经尝试了所有粘性组合,但不要调整按钮大小的组合仍允许它们四处移动,这是我不想要的。

编辑:根据要求,这是我所谈论的一个非常基本的例子。调整窗口大小时,按钮会相互分开。我不想要那个。

另一方面,即使我使用一列或一行,列/行占用了所有空间,我是否需要在末尾设置所有这些网格配置来设置权重?

import tkinter
from tkinter import *
from tkinter import ttk

class Application(tkinter.Tk):
    def __init__(self, parent):
        tkinter.Tk.__init__(self, parent)
        self.minsize(300,300)
        self.parent = parent
        self.main()

    def main(self):

        self.grid()

        listbox = tkinter.Listbox(self, width=20, height=25, bg = 'grey')
        listbox.grid(padx=30, pady=30, columnspan=11,  sticky='NEW')

        bt1 = Button(self, width = 5, height = 5)
        bt1.grid(row=10, column=0, padx=(30,0), sticky='w')

        bt2 = Button(self, width = 5, height = 5)
        bt2.grid(row = 10, column=1, sticky='w')

        bt3 = Button(self, width = 5, height = 5)
        bt3.grid(row = 10, column=2, sticky='w')

        bt4 = Button(self, width = 5, height = 5) 
        bt4.grid(row = 10, column=3, sticky='w')

        bt5 = Button(self, width = 5, height = 5)
        bt5.grid(row = 10, column=4, sticky='w')

        self.grid_columnconfigure(0,weight=1)
        self.grid_columnconfigure(1,weight=1)
        self.grid_columnconfigure(2,weight=1)
        self.grid_columnconfigure(3,weight=1)
        self.grid_columnconfigure(4,weight=1)
        self.grid_columnconfigure(5,weight=1)
        self.grid_columnconfigure(6,weight=1)
        self.grid_columnconfigure(7,weight=1)
        self.grid_columnconfigure(8,weight=1)
        self.grid_columnconfigure(9,weight=1)
        self.grid_columnconfigure(10,weight=1)      
        self.grid_rowconfigure(0,weight=1)
        self.grid_rowconfigure(1,weight=1)
        self.grid_rowconfigure(2,weight=1)
        self.grid_rowconfigure(3,weight=1)
        self.grid_rowconfigure(4,weight=1)
        self.grid_rowconfigure(5,weight=1)
        self.grid_rowconfigure(6,weight=1)
        self.grid_rowconfigure(7,weight=1)
        self.grid_rowconfigure(8,weight=1)
        self.grid_rowconfigure(9,weight=1)
        self.grid_rowconfigure(10,weight=1)

app = Application(None)
app.mainloop()

通过为网格中的所有行和列提供非零权重,您可以使用主窗口显式调整它们。

由于您只希望列表框调整大小,因此仅对行和包含列表框的列之一赋予非零权重:

def main(self):
    ...
    # The default weight of all rows/columns is 0. Only modify it for row 0 and column 10
    self.grid_rowconfigure(0, weight=1)
    self.grid_columnconfigure(10, weight=1)
