Installation​

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

Usage​

#include <shadcn/navigation.hpp>

shadcn::Menubar bar(parent);
auto& file = *bar.addMenu("File");
file.addAction("Open");

API​

Menubar inherits QMenuBar; use Qt menu and action methods for submenus and commands.

Variations​

Use platform menu bar integration when the host window provides one.

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.
