Installation​

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

Usage​

#include <shadcn/overlays.hpp>

shadcn::Drawer drawer(&window);
drawer.setTitle("Edit profile");
drawer.setDescription("Make changes to your profile here.");
drawer.open();

Add controls to content() and actions to footer().

API​

The drawer inherits the sheet side, panel and modal behavior. It uses the bottom edge and adds a drag handle.

Keyboard and accessibility​

Keep a visible title and a clear close action. The drawer restores focus after closing.
