【中文标题】Tkinter 窗口字体在拉伸窗口时动态扩展【英文标题】:Tkinter window font to expand dynamically while stretching the window 【发布时间】:2020-09-11 19:36:29 【问题描述】:我创建了一个 Tkinter GUI,我想在窗口扩展时使字体扩展。到目前为止,我已经尝试过权重,但只有窗口扩展而不是字母。以下脚本是我尝试创建的代码示例。
from tkinter import ttk
import tkinter as tk
from tkinter.scrolledtext import ScrolledText
from tkinter import*
from tkinter.ttk import *
master = tk.Tk()
#Title of GUI
master.title("Test Name")
#Seperate first GUI tab in sections
stepOne = tk.LabelFrame(master, text=" 1. General Heatmaps: ")
stepOne.grid(row=0, columnspan=7, sticky='WE', \
padx=10, pady=10, ipadx=10, ipady=10)
master.rowconfigure(1, weight=1)
master.columnconfigure(1, weight=1)
# this wil create a label widget
l1 = Label(stepOne, text = "Input tilt:")
l2 = Label(stepOne, text = "Input wind speed:")
l3= Label(stepOne, text = "Input path:")
# grid method to arrange labels in respective
# rows and columns as specified
l1.grid(row = 1, column = 0, sticky = E, pady = 2)
l2.grid(row = 2, column = 0, sticky = E, pady = 2)
l3.grid(row = 3, column = 0, sticky = E, pady = 2)
entryTilt = Entry(stepOne)
entryWind = Entry(stepOne)
entryFolder_path=Entry(stepOne)
entryTilt .grid(row = 1, column = 1, pady = 2)
entryWind .grid(row = 2, column = 1, pady = 2)
entryFolder_path .grid(row = 3, column = 1, pady = 2)
b1 = Button(stepOne, text = "Run script")
b1.grid(row = 2, column = 2, sticky = E)
master.mainloop()
【问题讨论】:
改字体大小而不是布局,对吧? 是的,这是我的目标 您要更改所有内容的字体大小,还是只更改某些小部件? 字体大小是原来的目标,但我想看看如果我改变一切会是什么样子 【参考方案1】:试试这个:
from tkinter import ttk
import tkinter as tk
from tkinter.scrolledtext import ScrolledText
from tkinter import *
# from tkinter.ttk import *
wh_font_map = k: v for k, v in zip(range(200, 1900, 50), range(10, 44))
#
# 200: 10,
# 250: 11,
# 300: 12,
# 350: 13,
# 400: 14,
# 450: 15,
# 500: 16,
# 550: 17,
# 600: 18,
# 650: 19,
# 700: 20,
# 750: 21,
# 800: 22,
# 850: 23,
# 900: 24,
# 950: 25,
# 1000: 26,
# 1050: 27,
# 1100: 28,
# 1150: 29,
# 1200: 30,
# 1250: 31,
# 1300: 32,
# 1350: 33,
# 1400: 34,
# 1450: 35,
# 1500: 36,
# 1550: 37,
# 1600: 38,
# 1650: 39,
# 1700: 40,
# 1750: 41,
# 1800: 42,
# 1850: 43
#
def change_font(event):
font_size = wh_font_map[next(k for k in wh_font_map if (master.winfo_width() + master.winfo_height()) / 2 <= k)]
for widget in stepOne.winfo_children():
widget['font'] = ("", font_size)
master = tk.Tk()
# Title of GUI
master.title("Test Name")
# Seperate first GUI tab in sections
stepOne = tk.LabelFrame(master, text=" 1. General Heatmaps: ")
stepOne.grid(row=0, columnspan=7, sticky='WE', \
padx=10, pady=10, ipadx=10, ipady=10)
# master.rowconfigure(0, weight=1)
# master.columnconfigure(0, weight=1)
# this wil create a label widget
l1 = Label(stepOne, text="Input tilt:")
l2 = Label(stepOne, text="Input wind speed:")
l3 = Label(stepOne, text="Input path:")
# grid method to arrange labels in respective
# rows and columns as specified
l1.grid(row=1, column=0, sticky=E, pady=2)
l2.grid(row=2, column=0, sticky=E, pady=2)
l3.grid(row=3, column=0, sticky=E, pady=2)
entryTilt = Entry(stepOne)
entryWind = Entry(stepOne)
entryFolder_path = Entry(stepOne)
entryTilt.grid(row=1, column=1, pady=2)
entryWind.grid(row=2, column=1, pady=2)
entryFolder_path.grid(row=3, column=1, pady=2)
b1 = Button(stepOne, text="Run script")
b1.grid(row=2, column=2, sticky=E)
master.bind("<Configure>", change_font)
master.mainloop()
只是一个想法。
我的想法:
-
为窗口绑定一个事件。
获取窗口高度和宽度的平均值。使用字典
wh_font_map
获取字体大小。(您可以更改范围)
wh_font_map
将生成一个average-font size
mapper。您可以手动更改它。
设置ttk.Button
的字体大小需要使用ttk.Style()
。
为了方便,我把它改成tk.Button
。如果你真的需要使用ttk.Button()
。阅读ttk-Style
