Question about QAction

[rock37]

Hey folks,
i have the following code:

 QToolButton *_log_type_button = new QToolButton(this);
  _log_type_button->setIcon(QIcon(":/res/images/debug_log_messages.png"));
  _log_type_button->setCheckable(true);
  _log_type_button->setPopupMode(QToolButton::InstantPopup);
  _log_type_button->setMaximumSize(36,36);
  std::cout << "QToolButton created" << std::endl;

  auto a1 { new QAction("Show log messages") };
  a1->setCheckable(true);
  a1->setIcon(QIcon(":/res/images/debug_log_messages.png"));
//  a1->setChecked(Application::settings().value("LogMessages", true).toBool());

  auto a2 { new QAction("Show log warnings") };
  a2->setCheckable(true);
  a2->setIcon(QIcon(":/res/images/debug_log_warnings.png"));
//  a2->setChecked(Application::settings().value("LogWarnings", true).toBool());

  auto a3 { new QAction("Show log errors") };
  a3->setCheckable(true);
  a3->setIcon(QIcon(":/res/images/debug_log_errors.png"));
 // a3->setChecked(Application::settings().value("LogErrors", true).toBool());
  std::cout << "Actions created.. " << std::endl;

  _log_type_button->addAction(a1);
  _log_type_button->addAction(a2);
  _log_type_button->addAction(a3);

now my question is how can i make a function call when one of the icons is clicked.

best regards,
stuv

Look at the link I mentioned in your previous post, you will find:

void MainWindow::createActions(){
    alignLeftAction = new QAction("Align left", this);
    alignCenterAction = new QAction("Align center", this);
    alignRightAction = new QAction("Align right", this);

    alignLeftAction->setIcon(QIcon(":/icons/alignLeft.png"));
    alignCenterAction->setIcon(QIcon(":/icons/alignCenter.png"));
    alignRightAction->setIcon(QIcon(":/icons/alignRight.png"));

    QObject::connect(alignLeftAction, SIGNAL(triggered()), 
                                this, SLOT(alignLeft()));
    QObject::connect(alignCenterAction, SIGNAL(triggered()), 
                                  this, SLOT(alignCenter()));
    QObject::connect(alignRightAction, SIGNAL(triggered()), 
                                  this, SLOT(alignRight()));
}

The SIGNAL - SLOT syntax will never die, as long as it's being taught to new Qt users 😅🤣
