tkinter

问题 I would like to have my scrollbar in the bottom of the frame and my text widgets filling the whole frame above the scrollbar. I found some solution about the width configuration here but when I try to replace width with height, it does not work correctly. from tkinter import * from tkinter import ttk class MainView(Frame): def FrameHeight(self, event): canvas_height = event.height self.canvas.itemconfig(self.canvas_frame, height=canvas_height) def OnFrameConfigure(self, event): self.canvas

问题 While extending the code based on this awesome Bryan Oakley's answer (btw his code works great, it's just me the one that can't make the padding work) I've found that the argument ipadx passed to .grid() is being ignored on the line: e.grid(row=row, column=column, sticky=tk.N+tk.E+tk.S+tk.W, ipadx=5, ipady=3) from the following script: import tkinter as tk from tkinter import ttk class SimpleTableInput(tk.Frame): def __init__(self, parent, rows, columns): tk.Frame.__init__(self, parent) self.

问题 Is it possible to enlarge the tiny check box of the Checkbutton object? The size is out of proportion when increasing the text size. I searched through the following link (Checkbutton) and can't find anything about the actual size of the box.
