Simple circular loading indicator.

class qudi.util.widgets.loading_indicator.CircleLoadingIndicator(*args, cycle_time=1.2, indicator_length=960, indicator_width_ratio=0.2, **kwargs)

Bases: PySide2.QtWidgets.QWidget

Simple circular loading indicator. You can customize cycle period, indicator arc length and width. Animation will automatically start (stop) upon showing (hiding) the widget. The widget can be arbitrarily resized but the actual indicator will always maintain 1:1 aspect ratio and will be centered. The color of the indicator is chosen to be the current palette highlight color.

Indicator length must be specified as integer value in 1/16th of a degree. Indicator width ratio can be any value 0 < x <= 0.5
