我开始在python中使用TK为我的程序构建图形界面。我无法解决有关 (1( 按钮在窗口中的位置和 (2( 在功能中使用单选按钮值的 2 个问题。
这是我当前的代码:
root = tk.Tk()
root.title("START")
root.geometry("500x200+500+200")
v = tk.IntVar()
v.set(0) # initializing the choice
my_choise = [
("Basic",1),
("Advanced",2),
('Extreme',3)
]
def ShowChoice():
print(v.get())
tk.Label(root,
text="""Choose your configuration:""",
justify = tk.LEFT,
padx = 20).pack()
val = 0
for val, choise in enumerate(my_choise):
tk.Radiobutton(root,text=choise,padx = 20,variable=v,command=ShowChoice,value=val).pack(anchor=tk.W)
def star_program(value):
os.system("ifconfig")
def open_comments_file():
os.system("gedit /home/user/Desktop/comments.txt")
def open_links_file():
os.system("gedit /home/user/Desktop/links.txt")
frame = tk.Frame(root)
frame.pack()
open_file_c = tk.Button(frame,
text="Comments",
command=open_comments_file)
open_file_f = tk.Button(frame,
text="Links",
command=open_links_file)
button = tk.Button(frame,
text="Start",
command=star_program(v.get()))
button.pack(side=tk.LEFT)
open_file_f.pack(side=tk.LEFT)
open_file_c.pack(side=tk.LEFT)
slogan = tk.Button(frame,
text="Cancel",
command=quit)
slogan.pack(side=tk.LEFT)
root.mainloop()
我希望按钮">链接"和"评论"位于单选按钮下方,一个位于另一个下方。现在,所有按钮都排成一行,但我希望在窗口底部有"开始"和"取消"。
然后我尝试在star_program函数中使用单选按钮(选择(的值。它不起作用。我的想法是,根据单选按钮中选择的选项,在单击"开始"按钮时执行不同的操作:
def star_program(value):
if value == 0:
os.system("ifconfig")
else:
print "Goodbye"
另外,关于"开始"按钮,我有一个奇怪的行为。如果我不单击"开始",程序也会运行"ifconfig"命令。如果我单击"开始",它不会执行任何操作。
有什么建议吗?谢谢!!!
我假设这更像你所追求的:
root = tk.Tk()
root.title("START")
root.geometry("500x200+500+200")
v = tk.IntVar()
v.set(0) # initializing the choice
my_choise = [
("Basic",1),
("Advanced",2),
('Extreme',3)
]
def ShowChoice():
print(v.get())
tk.Label(root,
text="""Choose your configuration:""",
justify = tk.LEFT,
padx = 20).grid(column=1, row=0, sticky="nesw") # use grid instead of pack
root.grid_columnconfigure(1, weight=1)
val = 0
for val, choise in enumerate(my_choise):
tk.Radiobutton(root,text=choise,padx = 20,variable=v,command=ShowChoice,value=val).grid(column=1, row=val+1, sticky="nw")
def star_program(value):
os.system("ifconfig")
def open_comments_file():
os.system("gedit /home/user/Desktop/comments.txt")
def open_links_file():
os.system("gedit /home/user/Desktop/links.txt")
frame = tk.Frame(root)
frame.grid(column=1, row=4, sticky="nesw")
open_file_c = tk.Button(frame,
text="Comments",
command=open_comments_file)
open_file_f = tk.Button(frame,
text="Links",
command=open_links_file)
button = tk.Button(frame,
text="Start",
command=lambda: star_program(v.get()))
# use lambda to create an anonymous function to be called when button pushed,
needed for functions where arguments are required
button.grid(column=2, row=3, sticky="nesw")
open_file_f.grid(column=1, row=1, sticky="nesw")
open_file_c.grid(column=1, row=2, sticky="nesw")
slogan = tk.Button(frame,
text="Cancel",
command=quit)
slogan.grid(column=4, row=3, sticky="nesw")
root.mainloop()
<</div>
div class="one_answers"> "开始"按钮的问题是由于函数定义。这是正确的代码,如果您不单击该按钮,则不会触发任何操作:
button = tk.Button(frame,
text="Start",
command=star_program)
