How to set border on a widget

user001

I have a QWidget class which will be added to a mainWindow. There will be some buttons, label on this widget. I want to have a border on it and to let user know the area of this widget. Searched online and cannot find a clear and direct answer. anybody here can help me with this? Or the border belongs to layout?

The easiest would be to base your widget on QFrame, not QWidget and set the "frameShape":http://qt-project.org/doc/qt-5.0/qtwidgets/qframe.html#frameShape-prop

Another option is to use qss like this:

yourWidget->setStyleSheet("border: 1px solid red");

Hi,
Have had the same problem some time ago and all my search lead to nothing,so I got creative.I inherited QWidget and in the paint event I drew the rectangle to act as my border.The next chunk of code should speak better:

void mCustomWidget::paintEvent(QPaintEvent *e)
{
    QPainter painter(this);

    painter.drawRoundedRect(0,5,width()-5, height()-7,3,3);

    QWidget::paintEvent(e);
}

Hope this helps.

The QFrame is the easy option. Layouts aren't used for borders etc, only for arranging widgets inside parent widget. If a label/title is needed, the QGroupBox is the way to go.
