:-) But you may find that useful too, as you cobble together a solution. If it were that easy I would have said so earlier This makes it fairly difficult to use to ask the widget *how far* off the Only get a bounding box if the text is currently visible on the screen. This is, however, probably not the answer you are looking for, because you To have by asking it for the geometric position of the last character with

How might I query the size of a fixed-width font in pixles? It appears that Use a fixed-width font and manually wrap.

You'll get a Text that will shrink and expand as much as you like. The "trick" is to create the Text as small as possible (width=1, height=1), make it fill its whole container (pack(fill=BOTH, expand=1)), then set the dimensions for the container window (geometry('500x200')). If you want a Text widget to be the smallest as possible in its container, you can do something like:
How do you create your Text widget? Do you specify a width and height? If you do not, the default width and height are 80 and 24 respectively, and the widget won't resize to less than that. This is supposed to be the regular behaviour. I would like for a tkinter text widget to be aware of how big the frame thatĬontains it is, then I would like for it to reset its width to theĪppropriate number of characters when this frame changes size.Įrrr.
