What I'm trying to do is launch a program within another program using `QProcess` and then save the output from the launched program into a `QTextEdit` of the launcher program. Every time I launch this program I want it to add more text to the `QTextEdit`. Now I get the program to launch but then after the text is supposed to be written it crashes. Here is the code:

```
#include <QWidget>
#include <QPushButton>
#include <QTextEdit>
#include <QProcess>
#include <QVBoxLayout>
#include <QApplication>

class Widget : public QWidget
{
    Q_OBJECT
    QTextEdit* text;
public:
    Widget() : text(new QTextEdit) {
        QPushButton* addBtn = new QPushButton("Add Module");
        text->setReadOnly(true);
        QVBoxLayout* layout = new QVBoxLayout(this);
        layout->addWidget(addBtn,0);
        layout->addWidget(text);
        connect(addBtn,SIGNAL(clicked()),SLOT(launchModule()));
    }
    Q_SLOT void launchModule() {
        QString program = "C:/A2Q2-build-desktop/debug/A2Q1.exe";
        QProcess *myProcess = new QProcess(this);
        connect(myProcess, SIGNAL(finished(int)), SLOT(finished()));
        connect(myProcess, SIGNAL(error(QProcess::ProcessError)), SLOT(finished()));
        myProcess->start(program);
    }
    Q_SLOT void finished() {
        QProcess *process = qobject_cast<QProcess*>(sender());
        QString out = process->readAllStandardOutput(); // will be empty if the process failed to start
        text->append(out);
        delete process;
    }
};

int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    Widget w;
    w.show();
    app.exec();
}

#include "main.moc"

```
