As in Qt to make a combobox similar to the settings (⋮) in Android

Hi!
As in QWidget to make a combobox similar to the settings (⋮) in Android

mrjj

Hi
Im not sure how that looks or works..
What is the difference from a normal combobox ?

Mikeeeeee

So it is possible, but how to bind the slot to choice?

    QMenu* menu = new QMenu(this);
    menu->addAction(tr("Настройки"));
    menu->addAction(tr("О программе"));
    ui->pushButton->setMenu(menu);

Hi
https://doc.qt.io/qt-5/qmenu.html#addAction
returns the action so you can connect to its triggered() signal

Mikeeeeee

Did so, but the slot does not start:

    QMenu* menu = new QMenu(this);
    menu->addAction(tr("Настройки"));
    menu->addAction(tr("О программе"));
    ui->optionButton->setMenu(menu);

    connect(menu, SIGNAL(triggered()), this, SLOT(testSlot()));

mrjj

hi
and what does connect return ?
If you check the docs, you will see that it has a parameter.
so i think you connect is invalid.

connect(menu, SIGNAL(triggered(bool)), this, SLOT(testSlot(bool)));
and make sure the testSlot do in fact take a bool. ( by adding it )

Mikeeeeee

It works:

connect(menu, SIGNAL(aboutToShow()), this, SLOT(testSlot()));

It's not work:

    connect(menu, SIGNAL(triggered(tr("Настройки"))), this, SLOT(testSlot()));

I need to get the signal right from the menu.

Ant this not works:

    QMenu* menu = new QMenu(this);
    QAction *action0 = new QAction(this);
    QAction *action1 = new QAction(this);
    action0->setText("Настройки");
    action1->setText("О программе");
    menu->addAction(action0);
    menu->addAction(action1);
    //menu->addAction(tr("Настройки"));
    //menu->addAction(tr("О программе"));
    ui->optionButton->setMenu(menu);

    connect(menu, SIGNAL(triggered(action0)), this, SLOT(testSlot()));

    connect(menu, SIGNAL(triggered(action0)), this, SLOT(testSlot()));

You should write the prototype of the signal.

void QMenu::triggered(QAction *action)
void QAction::triggered(bool checked = false)

So, if you are trying to use these signal then you could follow the below examples

connect(menu, SIGNAL(triggered(QAction*)), this, SLOT(testSlot()));
// OR
connect(action0, SIGNAL(triggered(bool)), this, SLOT(testSlot()));
connect(action1, SIGNAL(triggered(bool)), this, SLOT(testSlot()));

Note: QMenu::triggered pass the triggered action as parameter while QAction::triggered is useful to connect a specific action to specific slots.

Thanks, it's working!

@Mikeeeeee
Use a simple stylesheet on your button

ui->optionButton->setStyleSheet("QAbstractButton::menu-indicator{width:0}");
