QProcess not running command correctly & freezing gui

m00k

Hey,
I know the basics of C++ but am a total QT noob so please treat me accordingly.
This is the code in question:

@void gamemode::on_gamemodeoff_clicked()
{
QProcess startagain;
QString startCommand;
startCommand = ("easystroke & synapse"); // for launching easystroke and synapse (2 programs)

startagain.start(startCommand, QIODevice::ReadOnly);
startagain.waitForFinished(-1);

}
@
Whenever i run this and press the button my program only launches easystroke then freezes and doesn't launch synapse, what am i doing wrong?

Hi,

Try ; instead of &. Because I think the second program won't launch until first completes. I'm not sure though.

Thanks for the response,
If i use: @easystroke ; synapse@ the program does not freeze but still only launches easystroke.

And if i use: @easystroke &; synapse@ it still only launches easystroke but then freezes.

Hi,

Another way would be this
@
QProcess startagain;
QString startCommand;
startCommand = "easystroke";
startagain.startDetached(startCommand);
startCommand = "synapse";
startagain.startDetached(startCommand);
@

This will work but there must be more elegant way.

Still only launches easystroke and freezes :(.
