Removing border of QLineEdit

I have a bunch of QLineEdit boxes that I want to remove the borders from. Ideally I want to just do this with one line of code, rather than having to set no border for each QLineEdit box. I am trying to use QLineEdit::setFrame(false); but this returns illegal call of non-static member function. Suggestions?

Solution

  • You can set the style sheet for the application, or for the parent of those line edits:

    window()->setStyleSheet("QLineEdit { border: none }");

    or

    window()->setStyleSheet("QLineEdit { qproperty-frame: false }");

    The latter is equivalent to executing the following code:

    for(auto ed : window()->findChildren<QLineEdit*>())
  ed->setFrame(false);

    The window() refers to QWidget * QWidget::window() const.

    Since you want to do it application-wide, you can simply set the style sheet on the application:

    qApp->setStyleSheet("QLineEdit { qproperty-frame: false }");

    You can further use CSS selectors to override the frame on certain objects. You've got the power of CSS at your disposal.
