Hiding the cursor on QLineEdit

Jonikles

Pretty much the title. I have a QLineEdit and I want whenever the user clicks away on something else to stop the focus on the QLineEdit. If that's not possible then if you guys have any idea on how to completely remove the cursor in the first place that would also work.
Thanks!

But it doesn't work when clicking on a QFrame.. any way to change that?

call :
QFrame::setFocusPolicy(Qt::ClickFocus)

When you "click away to something else" that should remove the focus on the QLineEdit, and stop showing the cursor.

@JonB like automatically? if that's what you're saying then that is not what's happening for me. It's like this:
Until you start editing - no focus obviously, but once you do it never goes away unless I focus onto a different QEditLine but that's no solution.

@Jonikles
Implement an event filter on the parent window then,
when a click occurred on an other button, call clearFocus() on your line edit.

Depends on what/where clicking elsewhere is, I guess.

If you ( @Jonikles ) click/focus another widget or window, the cursor should definitely disappear.
Can you confirm that?!

What OS are you on? Which Qt version? Are we dealing with a default QLineEdit or any re-implementation or subclass?

But this sounds so weird, that it is too obvious to be a bug that stayed in for a longer time, no matter what Qt version.

@Pl45m4 oh yeah whenever I click on a different widget it disappears that's a brain fart on my end haha. But it doesn't work when clicking on a QFrame.. any way to change that?
BTW, if it helps in general:
Windows 10, QT 6.5, default QLineEdit.

Clicking on a QFrame or plain QWidget doesn't direct the focus to them per default. It triggers MouseClick / -ReleaseEvents, but the focus stays at QLineEdit, therefore the cursor is staying visible. Same for any other widget, where you can select something. Selected QListWidgetItems stay selected, when clicking somewhere on an empty QWidget space (QFrame is also a QWidget).

To work around that, try what @mpergand suggested. Install an eventFilter and move the focus where you want it to be, when your QLineEdit has focus and your QFrame is clicked.

[Edit: @mpergand 's new solution works even better ;-) ]
