How to check if a Process is Running or Not
qt
Solution
From the docs for QProcess ...
There are at least 3 ways to check if a QProcess instance is running.
QProcess.pid() : If its running, the pid will be > 0
QProcess.state() : Check it again the ProcessState enum to see if its QProcess::NotRunning
QProcess.atEnd() : Its not running if this is true
If any of these are not working as you would expect, then you will need to post a specific case of that example.
Problem
I am starting a process using the below code ``` QProcess* process = new QProcess(); process->start(Path); ``` The start method will start a third party application. If the process is already running, I should not call process->start(Path) again. The process pointer is private member of the class.
