How to prevent the default blue border being drawn on QLineEdit focus

Question

I am trying to achieve a borderless QLineEdit through CSS. It works fine when the QLineEdit is not in focus but when in focus the default blue border always comes up. The simple CSS I am using:

QLineEdit, QLineEdit:focus { border: none; }

I have tried with different background color through CSS for focus and not-in-focus, it works but I am unable to remove the blue border while in focus. Just to inform, I am working on a Mac.

Your style sheet works for me in Windows. So does Nikos's solution. Maybe create a small compilable example on your Mac, and if the problem persists, file a bug report. – Camaraderie

Answer 1

You might get rid of the focus border by setting:

QLineEdit.setAttribute(Qt::WA_MacShowFocusRect, 0)

Read the documentation, there are plenty of other Mac specific settings WidgetAttribute-enum

There is rather a similar question too Refer this question

Thanks. But in QT5.4, it should be Qt::WA_MacShowFocusRect instead of Qt.WA_MacShowFocusRect – Cns

Answer 2

Maybe also like this way:

ui->treeView->setAttribute(Qt::WA_MacShowFocusRect, 0);
