Hi All,
I have designed a page which will take the script name and run it . I am currently using Qprocess to run the script and printing the out put on the textEdit.
The code works fine when I give a small script , but the GUI hungs and I saw SEGV when I tried to run a simple script which only do "ls" in a loop for 300 times .

I belive all the error is at the time of reading / printing of the data on the text Edit.

I have very less knowledge on both debugging and QT , I tried alot to find the issue but when run with GDB I found this
gdb) where
#0 0x00aa27a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2

301 int nselect = select(qt_qprocess_deadChild_pipe[0] + 1, &readset, 0, 0, 0);
Current language: auto; currently c++

As my above approch is blocking the GUI , Now I am need a way to read the out put of the process through a thread ... Can any body tell me how to create a thread which will take the script name as a argument and run it .
