Member Function Documentation
[explicit] AspectRatioLabel::AspectRatioLabel(QWidget *parent = nullptr)
Constructs the label with parent as parent.
[override virtual protected] bool AspectRatioLabel::event(QEvent *e)
Reimplements: QLabel::event(QEvent *e).
[override virtual] int AspectRatioLabel::heightForWidth(int w) const
Reimplements: QLabel::heightForWidth(int w) const.
[override virtual protected] void AspectRatioLabel::mousePressEvent(QMouseEvent *event)
Reimplements: QLabel::mousePressEvent(QMouseEvent *ev).
[override virtual slot] void AspectRatioLabel::resizeEvent(QResizeEvent *event)
Reimplements: QWidget::resizeEvent(QResizeEvent *event).
[slot] void AspectRatioLabel::setPixmap(const QPixmap &pixmap)
Sets the pixmap shown on the label. Setting a new pixmap clears the previous content.
Note: This redefines the non-virtual slot of the same signature from the QLabel base class, which results in non polymorphic behavior when called via a base class pointer.
[slot] void AspectRatioLabel::setPixmapAndUrl(const QPixmap &pixmap, const QString &url)
Sets the pixmap shown on the label and an url. Setting a new pixmap clears the previous content. When clicking the pixmap, url is opened in a browser. If the url is a reference to a file, it will be opened with a suitable application instead of a Web browser.
[override virtual] QSize AspectRatioLabel::sizeHint() const
Reimplements: QLabel::sizeHint() const.
