Array not sent from signal and slot
-
I want to send an array from one form(MainWindow) to another form(Dialog) upon a button click! Though the array seems to be sent it returns a wrong value! Following are my codes!
MainWindow.h
signals:void sendArray(int a[]);
MainWindow.cpp
void MainWindow::on_pushButton_clicked()
{
int a[] = {1,2,3};
Dialog dialog1;
connect(this,SIGNAL(sendArray(int[])),&dialog1,SLOT(receiveArray(int[])));
emit sendArray(a);dialog1.exec();}
Dialog.h
public slots:
void receiveArray(int a[]);Dialog.cpp
void Dialog::receiveArray(int a[]){
int value=a[0];
QString value1=QString::number(value);
ui->label->setText(value1);
}When the program is run(no compile errors occur) and the button is clicked though 1 (0th index of the array) should printed on the label in Dialog form a wrong value 8441124 is printed. How can I correct this?

Hi
old type c array can also work.
Its just a matter of what is registered already.
You can register your own types.
