In general, what decorations the WM (window manager) decides to display can not be easily dictated by a toolkit like Tkinter. So let me summarize what I know plus what I found: import Tkinter as tk root= tk.Tk() root.title(“wm min/max”) # this removes the maximize button root.resizable(0,0) # # if on MS Windows, this might … Read more
You can also force an update right away without entering your mainloop, by using something like this: root = Tk() # set up widgets here, do your grid/pack/place # root.geometry() will return ‘1×1+0+0’ here root.update() # now root.geometry() returns valid size/placement root.minsize(root.winfo_width(), root.winfo_height()) Description of update() at effbot tkinterbook: Processes all pending events, calls event … Read more
You can either generate a postscript document (to feed into some other tool: ImageMagick, Ghostscript, etc): from Tkinter import * root = Tk() cv = Canvas(root) cv.create_rectangle(10,10,50,50) cv.pack() root.mainloop() cv.update() cv.postscript(file=”file_name.ps”, colormode=”color”) root.mainloop() or draw the same image in parallel on PIL and on Tkinter’s canvas (see: Saving a Tkinter Canvas Drawing (Python)). For example … Read more
The Tkinter Label widget does wrap. It is just that the default setting is no wrapping. To get the text on one to wrap set the wraplength parameter, the units for this are screen units so try wraplength=50 and adjust as necessary. You will also need to set justify to LEFT, RIGHT, or CENTER.
To get the value out of a label you can use the cget method, which can be used to get the value of any of the configuration options. For example: l = tk.Label(text=”hello, world”) … print(“the label is”, l.cget(“text”)) You can also treat the object as a dictionary, using the options as keys. Using the … Read more
In addition to the above answers: even though there are a lot of proposed solutions for this (here and also in this other thread), I was struggling quite a bit to make this work myself. Eventually I ran into this text handler class by Moshe Kaplan, which uses a ScrolledText widget (which is probably easier … Read more
Your first line in choices variable doesn’t have an apostrophe (‘) at the end.
In Python 3, it’s tkinter with a small t, and you need to import it. Thus: >>> import tkinter >>> tkinter.TkVersion 8.6 If you didn’t import it, you’d get the error you mentioned.
Neither is intrinsically better than the other. Each have strengths and weaknesses. Learn what those are and the choice of which to use becomes obvious. grid is considerably easier to use if you need to lay things out in a grid. pack is generally easier to use if all you need to do is put … Read more
The method you are looking for is winfo_children. Recursive like this: def all_children(wid, finList=None, indent=0): finList = finList or [] print(f”{‘ ‘ * indent}{wid=}”) children = wid.winfo_children() for item in children: finList.append(item) all_children(item, finList, indent + 1) return finList
