How to show Error-Message in a separate Window ?

Hello,

if in programms occur an error, a messagebox will be displayed
with a message and some other information.

How can I do that in a blender python script.

Thanks.

If an error occurs in a python script in blender the error is printed in the console. In windows this is the first of the two windows that open when you start blender.
On other operating systems it’s the same, but the console doesn’t always automatically show. You’ll have to ask someone with another OS how you can make it show up, since I only have windows experience.
