Get the length in characters of a PyGTK TextView

Question

我在最大化的窗口中有一个gtk TextView，我想知道在滚动之前一行可以容纳多少个字符。

Answer 1

(Friendly reminder, please stop putting answers in the comments, people.)

To summarize:

It depends on the size of the TextView, size of the window, size of the font, and as Alex Martelli said, the particular font and the usage of letters..."i" is a narrow letter, "m" is a wide letter, thus you can fit more "i"s than you can "m"s in a given space.

So, in short, there is no way to know for sure.
