我们指定字体是 Lucida Grande 系列,字体大小为 20,并且将该字体赋给标签 labelExample。 def increase_label_font(): fontsize = fontStyle['size'] labelExample['text'] = fontsize+2 fontStyle.configure(size=fontsize+2) 字体大小用 tkinter.font.configure() 方法更新。如从 gif 动画中看到的,使用该特...
1、设置label的字体、颜色、背景色、宽、高 from tkinter import * root = Tk() labelfont = ('times', 20, 'bold') # family, size, style widget = Label(root, text='Hello config world') widget.config(bg='black', fg='yellow') # yellow text on black label widget.config(font=labelfont)...

Tkinter actually has a variety of ways in which we may change the font type and size. Tkinter has several built in fonts, which can complicate things, especially when you realize that Each widget only uses one of these fonts. However, this also gives us the option to individually change th...
...第二步:给控件添加一个方法 代码: from tkinter import * import tkinter.messagebox #创建一个主窗口 root = Tk() # 创建 宽400高250的窗口...x是小写的英文字符 root.geometry('400x250') # 添加一个改变标签内容的方法 # 当scale控件滑块变化,会传入一个v变量,名字可以随便取 def change_label(....

Tkinter居然没有这种组件，所以就只能模拟了 ! /usr/bin/python# -*- coding: utf8 -*-from Tkinter import *class Select(Frame): def __init__(self, master=None): Frame.__init__(self, master) self.label = Label(self, text="选择项目") self.listBox = Listbox(sel...
