Installation​

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

Usage​

#include <shadcn/feedback.hpp>

shadcn::Bubble bubble("Thanks for the update", parent);
bubble.setAlign(shadcn::BubbleAlign::End);
bubble.setVariant(shadcn::BubbleVariant::Secondary);

API​

setText, setVariant and setAlign update the surface. content() and addWidget accept richer content.

Variations​

Use start or end alignment and the default, muted, tinted, outline, ghost or destructive variants.

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.
