![]() I do not know what Qt does with this in its framework. For a program to work in some custom way you would need to add custom signal handlers, but not all signals can be “caught”. The behavior seen isn’t specific to a Jetson. When you see SIGSTOP, think of it as CTRL-z. “fg” when ready to run the process in foreground. Try either running the program as normal, but " &" at the end, or else running the commadn “bg” to continue in background. I wonder is there a way to do this in Qt Creator My current version is 2.3.1. It seems that what you are running as “console mode” is “suspend” instead. If you ran with “&”, then “fg” would remove the “&”. If you then run “fg”, then your original script takes that console.Īll of the combination of CTRL-z and “bg” command combination could be done with. The same thing, but giving you the ability to run new commands on the same terminal, run the program, CTRL-z, run “bg”, and watch the output…but realize you can now also run commands like “ls”. Run “fg” to put it in foreground…the program continues. Run the program, and after a few seconds hit CTRL-z. Only users with topic management privileges can see it. Script modified to display time once per second: #!/bin/bash Qt-creator-2.3.1: install problem Qt-creator-2.3.1: install problem This topic has been deleted. Normally you would do this sort of thing with a long running non-interactive program, e.g., a calculation or database operation taking hours or longer.Įxample, a shell script named “timestamp”: #!/bin/bash When you want to actually see the application again, run “fg”. In the background, Qt Creator runs qmlscene and passes your QML document as the. To do so you start by suspending the program, e.g., with CTRL-z, run command “bg” to continue while being able to run any other command in the foreground. Note that there is an option to continue a program running in background. For that you suspend the program, do whatever else, and then resume (“fg”). There have been times in history where people needed to interrupt long-running heavy-use programs on less powerful systems, run something short, and then resume. ![]() If you then run command “fg”, (short for “foreground”), then your program starts running again. The program still exists, but has essentially been given a breakpoint and is waiting to resume or terminate. ![]() On the keyboard, if you run a program, and then hit CTRL-z, it suspends (SIGSTOP). There is a second shorter way to describe what follows, but this explains the signals. What it does is indefinitely pause an application (until told to continue). A Qt Creator 2.3.1 patch release is now available through an Qt SDK update and as updated Qt Creator - only packages. This doesn’t cause execution in background, nor does it cause running without GUI. 1.1 QtCreator 1.2 -win32-win64 1.3 Qt \Tools\ QtCreator \lib\ qtcreator \plugins 2. I don’t know specifically about Qt, but SIGSTOP (and its counterpart, SIGCONT) are for suspending (or resuming) a process.
