Menu
The menu control provides a context menu with support for nested items.
Quick Start
#include <wui/control/menu.hpp>
auto menu = std::make_shared<wui::menu>();
wui::menu_items_t items = {
{1, wui::normal, "Open", "Ctrl+O", nullptr, {}, [](int32_t id) {
open_file();
}},
{2, wui::normal, "Save", "Ctrl+S", nullptr, {}, [](int32_t id) {
save_file();
}},
{3, wui::separator, "", "", nullptr, {}, nullptr},
{4, wui::normal, "Exit", "Alt+F4", nullptr, {}, [](int32_t id) {
exit_app();
}}
};
menu->set_items(items);
// Show on right click
window->subscribe([&menu](const wui::event& ev) {
if (ev.type == wui::event_type::mouse &&
ev.mouse_event_.type == wui::mouse_event_type::right_up) {
menu->show_on_point(ev.mouse_event_.x, ev.mouse_event_.y);
}
}, wui::event_type::mouse);
Menu Item States
enum menu_item_state {
normal, // Normal item
separator, // Separator
expanded, // Expanded (with submenu)
disabled // Disabled
};
