Non-modal dialog forces app to exit.

[vereteran]

Hi.

The story: my app got tray icon with menu attached, there's a point in menu called Configure that raises non-modal dialog. If i press Ok or Cancel in dialog application exits.
No error messages or at least info, it just exits.

The code:

Handler:

void AppMainWindow::config() {
  if(!conf_dialog)
    conf_dialog=new ConfigDlg(this);
 
  conf_dialog->show();
  conf_dialog->raise();
  conf_dialog->activateWindow();
}

void AppMainWindow::config() {
  if(!conf_dialog)
    conf_dialog=new ConfigDlg(this);
  
  conf_dialog->show();
  conf_dialog->raise();
  conf_dialog->activateWindow();
}

Action creation:

configAction=new QAction(tr("&Configure..."),this);
  configAction->setStatusTip(tr("Displays configuration menu."));
  connect(configAction,SIGNAL(triggered()),this,SLOT(config()));

configAction=new QAction(tr("&Configure..."),this);
  configAction->setStatusTip(tr("Displays configuration menu."));
  connect(configAction,SIGNAL(triggered()),this,SLOT(config()));

Menu creation:

trayMenu=new QMenu(this);
  trayMenu->addAction(showAction);
  trayMenu->addAction(configAction);
  trayMenu->addSeparator();
  trayMenu->addAction(exitAction);

trayMenu=new QMenu(this);
  trayMenu->addAction(showAction);
  trayMenu->addAction(configAction);
  trayMenu->addSeparator();
  trayMenu->addAction(exitAction);

Tray icon creation:

tray=new QSystemTrayIcon(QIcon(":/icons/tray.png"),this);
  tray->setContextMenu(trayMenu);
  connect(tray,SIGNAL(activated(QSystemTrayIcon::ActivationReason)),this,SLOT(trayActivated(QSystemTrayIcon::ActivationReason)));
  tray->show();

tray=new QSystemTrayIcon(QIcon(":/icons/tray.png"),this);
  tray->setContextMenu(trayMenu);
  connect(tray,SIGNAL(activated(QSystemTrayIcon::ActivationReason)),this,SLOT(trayActivated(QSystemTrayIcon::ActivationReason)));
  tray->show();
