QMessageBox ( Core Dumped )

[cristiano]

Staff, the QMessageBox below functions normal. More when I pressed the Esc keyboard key, occurs Core dumped in the App.

% Segmentation fault (core dumped)

QMessageBox mb("App", "Hello Message ",
QMessageBox::NoIcon,
QMessageBox::Yes | QMessageBox::Default,
QMessageBox::Cancel, QMessageBox::Escape );
 
mb.setButtonText( QMessageBox::Yes, "Ok" );
mb.setButtonText( QMessageBox::Cancel, "Cancel" );
 
QPixmap exportSuccess( QPixmap::fromMimeSource( "message.png" ) );
mb.setIconPixmap(exportSuccess);
 
mb.exec();

QMessageBox mb("App", "Hello Message ",
QMessageBox::NoIcon,
QMessageBox::Yes | QMessageBox::Default,
QMessageBox::Cancel, QMessageBox::Escape );

mb.setButtonText( QMessageBox::Yes, "Ok" );
mb.setButtonText( QMessageBox::Cancel, "Cancel" );

QPixmap exportSuccess( QPixmap::fromMimeSource( "message.png" ) );
mb.setIconPixmap(exportSuccess);

mb.exec();
