How to uniformize a QFrame derived widget style with the QLineEdit style?

lano1106

I incorporated a widget that I got the source code from https://stackoverflow.com/a/11358560/3174651

It is a derived class from QFrame.

It works but it is not 100% correct, imho but the point is it has a slightly different appearance that the 2 other QLineEdit widgets in the dialog.

For one, the corners are square vs rounded corners for QLineEdit.

and secondly, the focus border color is different:
IPCtrl focus appearance:

QLineEdit focus appearance:

How do I change IPCtrl so that its frame is identical to QLineEdit widgets?

As a sidenote, the IPCtrl focus frame is something that I added with:

    else if (event->type() == QEvent::FocusIn) {
        m_pFocusFrame->setWidget(this);
    }
    else if (event->type() == QEvent::FocusOut) {
        m_pFocusFrame->setWidget(nullptr);
    }

in its eventFilter(QObject *obj, QEvent *event) function.

You should check its implementation: does it use style-sheets?

If you want the frame looks exatly like a QLineEdit, then don't use something like focus frame, just paint with the same PrimitiveElement as QLineEdit.

class IPCtrl : public QFrame
{
    Q_OBJECT
......
protected:
    void paintEvent(QPaintEvent *);
......
};

void IPCtrl::paintEvent(QPaintEvent *)
{
    QPainter p(this);
    QStyleOptionFrame option;
    initStyleOption(&option);
    //if (isReadOnly())
    //    option->state |= QStyle::State_ReadOnly;
    for ( int i = 0; i < QTUTL_IP_SIZE; ++i )
    {
        QLineEdit* pEdit = m_pLineEdit[i];
#ifdef QT_KEYPAD_NAVIGATION
        if(pEdit->hasEditFocus()) {
            option.state |= QStyle::State_HasEditFocus;
        }
#endif
        if(pEdit->hasFocus()) {
            option.state |= QStyle::State_HasFocus;
        }
    }
    style()->drawPrimitive(QStyle::PE_PanelLineEdit, &option, &p, this);
}

Other changes that need to be made from the code you posted:

IPCtrl::IPCtrl(QWidget *parent) : QFrame(parent)
{
......
    pLayout->setContentsMargins( 1, 1, 1, 1 );//if margin = 0 the frame would be blocked a bit
......
}

bool IPCtrl::eventFilter(QObject *obj, QEvent *event)
{
......
    if ( event->type() == QEvent::KeyPress )
    {
......
    } else if(event->type() == QEvent::FocusIn || event->type() == QEvent::FocusOut) {
            update(); //update the frame when the lineEdits have FocusIn/Out events
    }

    return bRes;
}
