[Qt-interest] How to make size of QLineEdit fit text content?

[Denis Akhmetzyanov]

Hi,
The quick and dirty decision is possible:

class MyWindow : public QWidget
{
    Q_OBJECT
public:
    MyWindow();

private slots:
    void resizeLineEditToContents();

private:
    QLineEdit *m_lineEdit;
};

MyWindow::MyWindow()
{
    resize(640, 480);

    m_lineEdit = new QLineEdit(this);
    connect(m_lineEdit, SIGNAL(textChanged(QString)), this,
SLOT(resizeLineEditToContents()));
}

void MyWindow::resizeLineEditToContents() {
    QString text = m_lineEdit->text();
    QFontMetrics fm = m_lineEdit->fontMetrics();
    int w = fm.boundingRect(text).width();
    m_lineEdit->resize(w, m_lineEdit->height());
}
