Signals and Slots with array

Beatsteak

Hi,

I am working with an extra workerthread in Qt which communicates with the mainwindow via Signals and Slots. This works fine so far. Now I want to send a signal containing 2 arrays from my workerthread to the mainwindow, which doesn't really work. Can anyone help me?

Here is a little extract from my code:

workerthread.h:

...
private:
   long val1[5];
   int val2[5];

signals:
   void testsignal(long val1[], int val2[]);
...

workerthread.cpp:

...
for (i=0;i<5;i++)
{
   val1[i] = i;
   val2[i] = 6-i;
}
emit testsignal(long val1, int val2);
...

mainwindow.h:

...
puclic slots:
   testslot(long val1[], int val2[]);
...

mainwindow.cpp:

...
MainWindow::MainWindow(QWidget *parent) :
   QMainWindow(parent),
   ui(new Ui::MainWindow)
{
   ...
   m_workerThread = new WorkerThread();

   connect(m_workerThread, SIGNAL(testsignal(long[],int[]), this, SLOT(testslot(long[],int[])));
   ...
}

...

void MainWindow::testslot(long val1[], int val2[])
{
   QString string = QString("Value 1 = %1 ,  Value 2 = %2").arg(val1[0]).arg(val2[0]);
   ui->textBrowser->append(string);
}

The output in my GUI is:
Value 1 = 889220 , Value 2 = 889260

jsulm

@Beatsteak You should either use std::array or QVector instead of array. Else in your slot you do not know how many elements the arrays contain.
And this is wrong:

emit testsignal(long val1, int val2);

it should be

emit testsignal(val1, val2);

Thanks! The QVector thing works :)
