Installation​

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

Usage​

#include <shadcn/feedback.hpp>

shadcn::Questionnaire flow(parent);
const int question = flow.addQuestion(
    "How should we contact you?", {},
    shadcn::QuestionnaireType::Single);
flow.addChoice(question, "email", "Email");
flow.addChoice(question, "phone", "Phone");
QObject::connect(&flow, &shadcn::Questionnaire::submitted,
                 receiver, onSubmitted);

API​

addQuestion returns an index. Add choices with addChoice, read answers with answer or answers, then call submit.

Variations​

Use QuestionnaireType::Multiple when a question accepts several choices.

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.
