QMessageBox "ok" button closes whole program.

Hey guys i'm new to qt and I'm trying to display an error by opening up a new QMessage box when when a button is clicked and an input was wrong.

Here's by code

@void errorFunction()
{
if(/some code/)
{

}

else
{
QMessageBox *msgBox== new QMessageBox();

msgBox->setText("You didn't enter a number 1-5! Try again");

msgBox->exec();
}

}@

Hi,

From where is errorFunction called ?

Note that you have a memory leak here. Either delete msgBox after the call to exec or allocate it on the stack.

Hi, errorFunction is called when I click a button. So I connected the button to this function like this:

@connect(rateButton,SIGNAL(clicked()),this,SLOT(errorFunction()));

What should be executed after that slot is called ?

And should that not be an assignment operator(=) instead of an equivalense test (==) operator
