ASpinnerV2#

Circular infinite progress indicator.

Header:#include <AUI/View/ASpinnerV2.h>
CMake:aui_link(my_target PUBLIC aui::views)

Detailed Description#

Rotates its contents as it renders. Unlike ASpinner, ASpinnerV2 allows to take more control over the animation - ASpinnerV2 draws at lower framerate which is better from perspective of resource usage. Generally, use ASpinnerV2 instead of ASpinner.

ASpinner's default style is a circular arc constantly and smoothly rotating around. ASpinnerV2's default style is a segmented circle which visually substains the "stepness" of the animation.

ASpinnerV2 is configured through ass :

    BackgroundImage { ":uni/svg/spinner_v2.svg", 0x993c3c43_argb },
    Margin { 4_dp },
    FixedSize { 16_dp },
