How can I make a default QPushButton respond to ENTER?

jdent

I have a QPushButton marked as default but when I press ENTER it is not activated - when my cursor is in a QLineEdit control for example. This is the code:

    connect(searchButton, &QPushButton::clicked, this, &PasswordManager::search);
    searchButton->setDefault(true);

What am I missing?

@jdent did you try pushButton->setShortcut(QKeySequence(Qt::Key_Enter));

See my discussion with @Chris-Kawa on this in https://forum.qt.io/topic/155461/qlineedit-returnpressed-when-something-else-has-a-key_return-shortcut. It might be worth trying Qt::Key_Return here, I suspect what you call the Enter key is what Qt calls the Return key. But it may be that those two are interchangeable, not sure.

It can certainly be done with a shortcut if you want, but I (think I) prefer @jsulm's suggestion of connecting returnPressed.

@jdent The default property of QPushButtons, instead will "press" the button whenever the top level widget receives the Return or Enter keys are pressed, no matter of the current focused widget, and as long as the focused widget does not handle those keys.So it does not apply to qlineedit

@Ronel_qtmaster I am sorry I don't understand what you are saying. Is there no way to make the button respond to ENTER? what if I set a shortcut?

Ronel_qtmaster

@jdent i mean setDefault will not work when there is a focus in the LineEdit.Appart from that it will work.If you add a shortcut it will work as well

jdent

@Ronel_qtmaster ok. How can I set a shortcut for the ENTER key?
I tried

searchButton->setShortcut(QKeySequence::StandardKey::)

but there is no key for ENTER or RETURN!

Ronel_qtmaster

@jdent did you try pushButton->setShortcut(QKeySequence(Qt::Key_Enter));

@Ronel_qtmaster I tried it - no results.

In MFC (Microsoft Foundation Classes) you can do this, I can't see why we can't do it in Qt...
There must be a way!!

When I press ENTER when inside the line edit, can't I take that keystroke and invoke the Search button?

@jdent Connect https://doc.qt.io/qt-6/qlineedit.html#returnPressed to https://doc.qt.io/qt-6/qabstractbutton.html#click

@JonB This did it!!

searchButton->setShortcut(QKeySequence(Qt::Key_Return));

Thanks all of you!!

@JonB Thanks for the hint

You might want to connect both Enter and Return. If I'm not mistaken, Enter is the key located in the NumPad area.

@SimonSchroeder See the discussion around https://forum.qt.io/topic/155461/qlineedit-returnpressed-when-something-else-has-a-key_return-shortcut/16 for the pointlessness/potential evilness of the NumPad Enter key ;-)
