Get more selectable options by clicking on a option

@developer_61 What about https://doc.qt.io/qt-5/qtoolbutton.html#setMenu ?

[developer_61]

@jsulm i think wouldn't work. i mean i have a QTtoolbar with QTactions in it.
So i need a method for QTactions.

@developer_61
You can add a QToolButton to a QToolBar by QAction *QToolBar::addWidget(QWidget *widget).
That's very common.
I happen to have some sample code.

    QMenu* menu = new QMenu(this);
    QAction* subAct1 = new QAction(QStringLiteral("SubAction1"));
    QAction* subAct2 = new QAction(QStringLiteral("SubAction2"));
    menu->addAction(subAct1);
    menu->addAction(subAct2);

    QToolButton* toolButton = new QToolButton(ui->toolBar);
    toolButton->setText(QStringLiteral("More"));
    toolButton->setMenu(menu);
    toolButton->setPopupMode(QToolButton::InstantPopup);
    ui->toolBar->addWidget(toolButton);

@Bonnie thank you very much. And it is possible to do that without coding? so directly in the qt designer?

[Bonnie]

@developer_61
Unfortunately I think that's not possible.

[developer_61]

@Bonnie yeah cause i try to add a tool button to the tool bar but thats not possible. Only Qactions is allowed.
But anyway thank you very much !

[developer_61]

another question ... @Bonnie
is it possible to hide that arrow next to the text

[Bonnie]

@developer_61
That's a frequently asked question :)
The easiest way is to use stylesheet.

toolButton->setStyleSheet("QToolButton::menu-indicator { image: none; }");

[developer_61]

@Bonnie thank you !!!
One last question:
is it possible to make an icon instad of more ?

[Bonnie]

@developer_61
Of course!
Just use toolButton->setIcon(...) (maybe also with toolButton->setIconSize(...)) instead of toolButton->setText(...).
It has the same functions as a QToolButton in the designer.

@Bonnie thank you !!
