Does QProcess::startDetached() must open a cmd-window?
-
On Win7, I am running the following code:
QProcess::startDetached(strCmd, QStringList(), ".", &m_nPid);the strCmd is a QString looks like "C:\Program Files\AutoDesk\Maya2014\bin\mayabatch.exe -file aFile -command aCommand".
It does start the mayabatch.exe but it gives me a black nuisance cmd-window.
How could I do to make it avoid showing the black cmd-window? -
You usually write the program into the first argument, and then the args to your program (one after the other) into the list, like: QProcess::startDetached(path_to_exe,arguments_list,".",&m_nPid).
But this has nothing to do with the black cmd-window. It always opens when you start a command-line program. It never opens if you start a "normal" windows program. It's a WINDOWS thing, nothing to do with Qt.

@DidaHarp
you can try to apply the provided patch and recompile Qt yourself if you fell like it.--- SUPPORT REQUESTS VIA CHAT WILL BE IGNORED ---

@raven-worx @m-sue Thanks a lot. Thank you for your responsible and thoughtful answer and such behavior is so rare in China.

Hi nice info,
so it seems from the message that
QProcess::start() might not always create a cmd-window?it says "
Instead, use the
same rules for deducing whether to show an console window or not as
QProcess::start()."Do we know what the rules are? ( besides looking in the code)

i do not.
But i think the code tells the most, since i expect it as pretty much platform specific.
