Property documentation

scaleFactor property

scaleFactor : qreal

This property holds the scale of the image, relative to the size that fits the label.

The label first fits the SVG or the pixmap into its own size and keeps the aspect ratio. Then it multiplies that size by this value and paints the image at the center. 1.0 is the fitted size. An animation of this value makes the pulse. A change emits scaleFactorChanged() and repaints the label. The default is 1.0.

Access functions:

  • qreal scaleFactor() const
  • void setScaleFactor(qreal factor)

Notifier signal:

  • void scaleFactorChanged(qreal)
