Elide текст QPushButton в Qt Symbian C ++ – 3 Ответа, The text of QPushButton can be set upon creation or using setText(). To get the It has been tested on Qt Symbian Simulator. An instance of  QPushButton:: QPushButton (const QIcon &icon, const QString &text, QWidget *parent = nullptr) Constructs a push button with an icon and a text, and a parent. Note that you can also pass a QPixmap object as an icon (thanks to the implicit type conversion provided by C++). [virtual] QPushButton:: ~QPushButton Destroys the push button.

Based on the Qt example for an elided label I came up with the following solution. It is mostly based on the Qt example, I have only simplified it according to my requirements:

HEADER:

/**
 * Push button with elided text
 * \remark based on http://doc.qt.io/qt-5/qtwidgets-widgets-elidedlabel-example.html
 */
class CElidedPushButton : public QPushButton
{
    Q_OBJECT
    Q_PROPERTY(QString text READ text WRITE setText)
    Q_PROPERTY(bool isElided READ isElided)

public:
    //! Constructor
    explicit CElidedPushButton(QWidget *parent = nullptr);

    //! Constructor
    explicit CElidedPushButton(const QString &text, QWidget *parent = nullptr);

    //! Text
    void setText(const QString &text);

    //! Text
    const QString &text() const { return m_content; }

    //! Elided?
    bool isElided() const { return m_elided; }

protected:
    //! \copydoc QPushButton::paintEvent
    void paintEvent(QPaintEvent *event) override;

private:
    bool m_elided = false;
    QString m_content;
};

CPP:

CElidedPushButton::CElidedPushButton(QWidget *parent) : QPushButton(parent)
{ }

CElidedPushButton::CElidedPushButton(const QString &text, QWidget *parent)
    : QPushButton(parent), m_elided(false), m_content(text)
{
    this->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Preferred);
}

void CElidedPushButton::setText(const QString &newText)
{
    m_content = newText;
    this->update();
}

void CElidedPushButton::paintEvent(QPaintEvent *event)
{
    QPainter painter(this);
    const QFontMetrics fontMetrics = painter.fontMetrics();
    const int usableWidth = qRound(0.9 * this->width());

    const QString elidedText = fontMetrics.elidedText(m_content, Qt::ElideRight, usableWidth);
    m_elided = (elidedText != m_content);
    QPushButton::setText(elidedText);
    QPushButton::paintEvent(event);
}

  • You requirement is not clear. Is it QPushButton or some other widget?? You can set text size by setting its stylesheet.
