I just came out of the shower this morning thinking, "Stupid boB,
stupid. That's just an escape sequence inside an overall string, not
an assignment statement." Duh! My brain works better asleep than
awake...

To be fair it did look like an assignment so when I first
saw it I too went "huh?!". But then I looked again and
figured it out. :-)

[Tutor] Multiple tabs using tkinter
Hi, I was wondering if someone could help me regarding multiple tabs in tkinter. I am working on a GUI which would have tabs similar to the ones we see in excel, wherein we can navigate from one tab to the other and back. Could you please direct me towards some information regarding how I should proceed with this issue. It would be a great help. Also, I was wondering if there is a way in tkinter to create an explorer bar that we see in finder in OS Mac or windows. I found a way to do that using wxpython, but was wondering if there is a way using tkinter. Please let me know. It would help me a lot. Would appreciate any help. thank you Pooja ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

You can build most things but you have to start with the basic widgets. So an explorer bar is just an Entry widget to which you can attach any functionality you care to create. The same applies to Status bars. In Tkinter its just a label in a frame that you have to update in your code. In other tookits there are status bar widgets that other widgets know how to use with just a reference. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

It just depends on what kind of style you prefer. (Some aim at leisure users with emphasis on games etc, others are targeted at more serious users and focus on, say, sysadmin type tasks, some are more academically correct, others easier to read but less rigorous). Try a couple and go with whatever looks most to your taste. If (when!) you get stuck or puzzled ask questions here. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Also have a look at ttk.Combobox, which combines an Entry and Listbox (and, I think, if the list is long enough, a Scrollbar) into a drop-down menu widget. -- Zach ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
