问题描述
限时送ChatGPT账号..我需要帮助在 tkinter 中制作字体对话框.
I need help making a font dialog in tkinter.
这是我目前的代码:
from tkinter import *
root = Tk()
root.geometry("600x600")
def fontDialog():
root2 = Toplevel(root)
root2.geometry("300x300")
root2.mainloop
button = Button(root, text="font dialog", command=fontDialog)
root.mainloop
所以在 def fontDialog 中,我做了一个屏幕.我不知道如何制作更改字体系列和大小的字体对话框.如果你这样做,请帮忙.
So in def fontDialog, I made a screen. I don't know how to make a font dialog that changes the font family and size. If you do please help.
推荐答案
字体选择器制作起来非常简单.你真正要做的就是在 font.families()
上运行一个循环,然后 insert
将每次迭代的返回值放入一个 Listbox
.从那里,您只需告诉它在单击 Listbox
时将持久字体引用的 family
更改为 Listbox
中选择的任何内容.对于将持久字体引用应用于其 font
选项的任何内容,字体都会更改.
A font chooser is very simple to make. All you really do is run a loop on font.families()
and insert
the return of each iteration into a Listbox
. From there, you just tell it to change the family
of a persistent font reference to whatever is selected in the Listbox
when the Listbox
is clicked. The font will change for anything that has the persistent font reference applied to its font
option.
import tkinter as tk
from tkinter import font
class App(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
#persistent font reference
textfont = font.Font(family='arial', size='14')
#something to type in ~ uses the persistent font reference
tk.Text(self, font=textfont).grid(row=0, column=0, sticky='nswe')
#make the textfield fill all available space
self.grid_rowconfigure(0, weight=1)
self.grid_columnconfigure(0, weight=1)
#font chooser
fc = tk.Listbox(self)
fc.grid(row=0, column=1, sticky='nswe')
#insert all the fonts
for f in font.families():
fc.insert('end', f)
#switch textfont family on release
fc.bind('<ButtonRelease-1>', lambda e: textfont.config(family=fc.get(fc.curselection())))
#scrollbar ~ you can actually just use the mousewheel to scroll
vsb = tk.Scrollbar(self)
vsb.grid(row=0, column=2, sticky='ns')
#connect the scrollbar and font chooser
fc.configure(yscrollcommand=vsb.set)
vsb.configure(command=fc.yview)
if __name__ == "__main__":
app = App()
app.title('Font Chooser Example')
app.geometry(f'800x600+200+200')
app.mainloop()
