Installation​

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

Usage​

#include <shadcn/controls.hpp>

shadcn::Toggle toggle("Preview", parent);
toggle.setVariant(shadcn::ToggleVariant::Outline);
toggle.setToggleSize(shadcn::ToggleSize::Sm);
toggle.setChecked(true);

API​

setVariant, setToggleSize, setInvalid and inherited check state define the control.

Variations​

Use default or outline variants and default, small or large sizes.

Keyboard and accessibility​

Qt supplies native focus, keyboard interaction and accessible object roles. Give the component a visible label or an accessible name when its text alone does not explain the action.

Ownership​

The parent widget owns the component. Child widgets created through a component layout follow Qt parent ownership. References returned by helper methods are borrowed.
