Installation​

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

Usage​

#include <shadcn/feedback.hpp>

shadcn::Toast toast(1, "Saved", "The file is ready.", parent);
toast.setType(shadcn::ToastType::Success);
toast.setActionText("Undo");
toast.show();

API​

setDuration, pause, resume and dismiss manage the lifetime. actionTriggered and dismissed report user actions.

Variations​

Use the default, success, info, warning, error or loading type.

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.
