Installation​

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

Usage​

#include <shadcn/widgets.hpp>

shadcn::Input input(parent);
shadcn::Label label("Course name", parent);
label.setBuddy(&input);

A label click focuses the buddy. A button buddy also receives activation.

API​

setBuddy stores a guarded reference to the target widget. The inherited QLabel text and alignment API remain available.

Keyboard and accessibility​

Use a visible label for every input that needs context. Qt handles focus transfer and mnemonic behavior for the connected control.
