Is there a way to enable word wrapping of text on some simple widgets like QPushButton?

Question

I\'d like to make QPushButton word wrap and expand it\'s height instead of expanding width. How can I do that?

Answer 1

For word wrapping in regular QPushButton you can implement proxy style class derived from QProxyStyle.

/**
proxy style for text wrapping in pushbutton
*/
class QtPushButtonStyleProxy : public QProxyStyle
{
public:
    /**
    Default constructor.
    */
    QtPushButtonStyleProxy()
        : QProxyStyle()
    {
    }

    virtual void drawItemText(QPainter *painter, const QRect &rect,
        int flags, const QPalette &pal, bool enabled,
        const QString &text, QPalette::ColorRole textRole) const
    {
        flags |= Qt::TextWordWrap;    
        QProxyStyle::drawItemText(painter, rect, flags, pal, enabled, text, textRole);
    }

private:
    Q_DISABLE_COPY(QtPushButtonStyleProxy)
};

And later in your own MyQtPushButton:

MyQtPushButton::MyQtPushButton()
   : QPushButton()
{
   setStyle(new QtPushButtonStyleProxy());
}

See additional information on QProxyStyle class in Qt documentation.
