问题 When I usually create a canvas, the (0, 0) coord is place on the top left corner of it. Now I want to set it on the bottom left corner. I think I have to set the "scrollbarregion" but I can't understand how to do it. Can someone explain? 回答1: The tkinter canvas does not support changing the coordinate system. You can scroll the canvas so that 0,0 appears in the bottom left corner, but that won't affect the coordinate system. Point (1,1) will always be to the right and below the point (0,0).

问题 In Tkinter for constructing the menubar with the <menu_item>.add_command() we need a string for the accelerator argument which will create the hotkey binding for a command. I created a method, which is checking if the user's platform is Mac or other, and if it is, then returns the Command key string combined with the other keys. But it doesn't work -> the menu is building, if I click on the menu-item it is working, but not working with the hot-keys. ALthough I can see the ⌘ + N in the menu..

问题 I'm trying to make tkcalendar blend in with my window. import tkinter from tkcalendar import Calendar window = tkinter.Tk() window.configure(background = "black") cal = Calendar(window, background = "black" , disabledbackground = "black" , borderbackground = "black" , headersbackground = "black" , normalbackground = "black" ) cal.config(background = "black") cal.pack() window.mainloop() I've read through the tkcalendar documentation and tried changing all the style elements by calling the

问题 With ttk one can produce code like the following: style.configure('TButton', font='helvetica 24',foreground='red', padding=10) Is there a list of the different options (e.g. font, foreground, padding) and the values (e.g. helvetica 24, red, 10) associated with each of them? I've been searching online and have yet to find such a reference. Also, is there a css-like thing we can use to style a TKinter GUI? Or is ttk my best bet? 回答1: Most information you should find in Tk Reference Manual. See

问题 Edit: I am referring to the OSX application menu, which contains the About and Preference menu items (along with others). Perhaps this will be another easy one for someone who knows the right search terms, but after spending hours tracing code in IDLE and searching the net, I haven't quite been able to connect the dots. I'm trying to replace the standard About menu in Python. IDLE does this at least part-way; the menu is still named "About Python" but it displays the IDLE About window. When

问题 I've tried this but it didn't help. I'm making a calculator program. I've made this so far: from tkinter import * window = Tk() disp = Entry(window, state='readonly', readonlybackground="white") disp.grid(column=0, row=0, columnspan=4) #row 1 seven = Button(window, text="7", command=Seven) seven.grid(column=1,row=1) eight = Button(window, text="8", command=Eight) eight.grid(column=2,row=1) nine = Button(window, text="9", command=Nine) nine.grid(column=3,row=1) divide = Button(window, text="÷"

问题 I'm using Python 2.7, if that matters. Here is a code I wrote for fun: def p(): root = Tk() def cmd(event): print int(slider.get()) slider = Scale(root, orient = "horizontal", from_ = 0, to = 100, command = cmd, state = "disabled") def enable(): slider.config(state = "active") b = Button(root, text = "Enable slider", command = enable) b.grid() slider.grid(row = 1) root.mainloop() For this code, I'm wondering why the command for Scale requires an event, but that for Button does not. It seems
