About QThread

[stevewang]

Hi all,

I have a command-line tool that I am calling using QThread.
One problem is that the command-line tool will crash if there is something wrong with the input data. However, I want the program to pop-up a dialog and tell the user to check the input data, rather than crash directly.

Is there any method to achieve this?

Thanks a lot.
