Why there are always dashed-line rectangle on QToolButton?

[FinderCheng]

I added a QToolButton onto a QToolBar. But the first button always has the dashed line ractangle around it. Even if I click other button, the first button still has that rectangle. I don't know how to remove it. Here I set each QToolButton as following code:

action = new QAction(this);
action->setIcon(icon);
action->setCheckable(true);
actionGroup->addAction(action);

action = new QAction(this);
action->setIcon(icon);
action->setCheckable(true);
actionGroup->addAction(action);

To copy to clipboard, switch view to plain text mode 

And then I create the QToolButton:

QToolButton * createToolButton(QAction *action)
{
    QToolButton *button = new QToolButton;
    button->setDefaultAction(action);
    button->setAutoRaise(true);
    return button;
}
// ...
QToolButton *button = createToolButton(action);
layout->addWidget(button , 0, 0, 1, 1);
// other butttons

QToolButton * createToolButton(QAction *action)
{
    QToolButton *button = new QToolButton;
    button->setDefaultAction(action);
    button->setAutoRaise(true);
    return button;
}
// ...
QToolButton *button = createToolButton(action);
layout->addWidget(button , 0, 0, 1, 1);
// other butttons

To copy to clipboard, switch view to plain text mode 

Please help me. Thank you all!

This is called "keyboard focus". Anyway, you shouldn't create tool buttons for actions yourself. Just add the action to a toolbar and a tool button will be created for you.

Yeah, I know I could add QAction onto QToolBar directly. But I want to have a grid-like tool bar with two columns. I don't know how to implement it so I added a QWidget with QGridLayout and then added this widget into tool bar therefore I have to create QToolButton myself.
Then how to remove this key focus or how to add actions into a tool bar with mutil-columns?

You can try setting the focus policy for each of the buttons to NoFocus.

Thanks! It works! Hope there is no side effects... :-)

The side effect is that you disabled keyboard navigation.
