how to change font size - barryjo - Jan-26-2022 I have a button defined below. What does 40 mean? Is there a 40 font? How do I change the font size. i.e. maker it larger or smaller? buttonGetAzEl=tk.Button(frame, text="GetAzEl", font = 40, command = GetAzEl) buttonGetAzEl.place(relx = 0.28, rely = 0.07, relheight=0.05, relwidth=0.20) RE: how to change font size - menator01 - Jan-26-2022 import tkinter as tk root = tk.Tk() root['padx'] = 8 root['pady'] = 4 tk.Label(root, text='Button with font and a size of10').pack() btn = tk.Button(root, text='Button 1', font=('tahoma 10')) btn.pack() tk.Label(root, text='Button with font and size of 40', font=('verdana 20')).pack() btn2 = tk.Button(root, text='Button 2', font=('verdana 40')) btn2.pack() tk.Label(root, text='Button with font and size of 20 and bold', font=('times 20 bold')).pack() btn3 = tk.Button(root, text='Button 3', font=('times 20 bold')) btn3.pack() root.mainloop() RE: how to change font size - barryjo - Jan-26-2022 This helps but what does the 40 mean" does it mean size 40 for a default font? If I change 40 to 20 nothing happens. ??? However, I Find I can change the font merely by naming the font and size as below. This seems simple. buttonGetAzEl=tk.Button(frame, text="GetAzEl", font = ('helvetica','30') , command = GetAzEl) RE: how to change font size - deanhystad - Jan-26-2022 You need to specify enough of a description that tkinter can create a font object. Size is not enough. times is a True Type font which is resizeable. import tkinter as tk root = tk.Tk() root['padx'] = 10 root['pady'] = 10 for size in range(8, 40, 2): tk.Label(root, text=f"This is font size {size}", font=(f"times {size}")).pack() root.mainloop() RE: how to change font size - menator01 - Jan-26-2022 To see the tkinter fonts you can do import tkinter as tk from tkinter import font root = tk.Tk() families = font.families() tk.Label(root, text=f'tkinter has {len(families)} fonts available.', font=('serif', 14, 'bold')).pack(side='top') scrollbar = tk.Scrollbar(root) scrollbar.pack(side='right', fill='y') text = tk.Text(root, width=75, yscrollcommand=scrollbar.set) for font_name in families: text.insert(tk.END, f'{font_name}\n') scrollbar.config(command=text.yview) text.pack(side='top', fill='x') root.mainloop() |
