[Solved] Two QtApp in the same window

[Beberd]

Hi,

I want to launch with my main application a QtApp in the same window.
For the moment, I have two windows...
Does-it possible?

Second point:
I want to use the QProcess Class, but I have problems with relative links.
I can't start a process with QProcess.
I do this : @system("cd ../../myApp ./myApp ");@
How can change directorty with QProcess?

Thanks,
Beberd

Hi, you don't need to change the directory in QProcess. Set proper working directory before you start you application

@
void QProcess::setWorkingDirectory(const QString & dir)

Hi,
You do not change directories with QProcess,you manipulate directories using "QDir":http://qt-project.org/doc/qt-4.8/qdir.html and give the processed final directory to QProcess.

Hope this helps

Thanks for your answers.
It works with this solution:
@void QProcess::setWorkingDirectory(const QString & dir)@

I have find another solution with:
@QDir::setCurrent(const QString &path);@

Yes, once you changed the current directory of parent process, it will be inherited by child process.

but note that, relative path used in your parent process will failed after this.
