    Default Clear focus on editingFinished

    I thought that when pressing the enter key on a QLineEdit, it would remove the focus (and the cursor wouldn't be visible anymore).
    For some reason it doesn't behave that way in this simple example. Can somebody explain why?

    Qt Code:
    1. LineEditTest::LineEditTest(QWidget *parent)
    2. : QWidget(parent)
    3. {
    4. QLineEdit *edit = new QLineEdit;
    5. Q_ASSERT(connect(edit, SIGNAL(editingFinished()), this, SLOT(SlotTextEdited())));
    7. l->addWidget(edit);
    8. setLayout(l);
    9. }
    12. void LineEditTest::SlotTextEdited()
    13. {
    14. QLineEdit *lineEdit = dynamic_cast<QLineEdit*>(sender());
    15. double value = lineEdit->text().toDouble();
    16. ...
    17. // lineEdit->clearFocus(); // If this line is enabled the cursor disappears
    18. }
    To copy to clipboard, switch view to plain text mode

    Default Re: Clear focus on editingFinished

    Return/Enter doesn't influence focus unless it is programmed to do so. Tab is the key for changing focus. By the way, using editingFinished() is probably not the proper way of doing what you want. "returnPressed()" would be a much better choice to react on the return key by losing focus. Of course editingFinished() is a good place to react on changes to the text of the edit.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
