Installation​

add_subdirectory(shadcn-cpp)
target_link_libraries(app PRIVATE shadcn::widgets)

Usage​

#include <shadcn/widgets.hpp>

shadcn::Progress progress(parent);
progress.setRange(0, 100);
progress.setValue(39);

Set both range bounds to zero to show an indeterminate track.

progress.setRange(0, 0);

API​

The public class keeps the QProgressBar range and value API. Determinate updates animate when full motion is enabled. Reduced motion updates the value without the transition.

Accessibility​

Set a useful accessible name on the progress widget. Provide nearby text when the numeric value alone does not explain what is loading.
