Hi,
I got below error message and crush when I work with the program.

ASSERT: "visual != -1" in file itemviews\qheaderview.cpp, line 1254

How can I check where the error comes from?

Hi,

Use a debugger and inspect the backtrace of the crash.

Hi @SGaist ,
Is there any document or video tutorial to do this?...

A quick search with the "Qt Creator debugging" keywords would have given you Qt Creator's documentation on how to setup for debugging as well as this VoidRealms video on the subject on youtube.
