由 女生的网名这么多〃 提交于 2019-12-10 05:35:10

Isn't there any method how to get the size of the usable part and not whole screen? Or at least get the sizes of the 'scrolling thing'

问题 CONTEXT I'm developing a Crossword game app that currently runs on iPad devices.

问题 I'm new to python and I'm using Python's IDLE. Using numpy, I created a 24 x 24 matrix. I simply want to look at the matrix. I've maximized the shell on my monitor, so there's plenty of room to print the entire 24 columns' width, but it's only printing the first 13 columns of then continuing onto the next line to print the next 11 columns (had trouble in Stack Overflow copying and pasting what it's doing). The entire right half of the Shell window is blank (it's compressing everything to fit

However, I'm not sure if there is any way to discover a users pixels per inch, ideally using JavaScript or some other non-invasive method. Any suggestions? Thanks, CJ 回答1: You could use the following javascript function to get the

问题 The existing answer is incorrect: Detect real screen resolution (ignoring browser zoom etc.) It will not show the screen resolution, but rather the document size.
