如何在D Programming Language + Tango中获取单键击中？

在D编程语言（D Language）和Tango中，可以通过捕获用户点击事件来获取单键击中的信息。具体操作步骤如下：

1. 注册D语言库中的输入捕获模块。在主程序或者窗体的构建函数中引入以下代码进行注册：void main() { init_input_capture(input_type::mouse_buttons); }d_app_window = new AppWindow(640, 480, "Input capture example"); if (!d_app_window->init()) { return; } add(new MyWindowComponent()); d_app_window->add_input_capture_receiver([](input_event const& evt) { // Use the input event information to determine which mouse button was clicked. return true; // Indicates that the event should be processed by the default handler }); d_app_window->run();void MyWindowComponent::update_mouse_state(input_event const& evt) { // Get mouse state information such as x and y coordinates. auto state = mouse_state{static_cast<float>(evt.x()), static_cast<float>(evt.y())}; // Check if the left mouse button was clicked. if (evt.type() == input_event_type::MouseButtonPress) { if (evt.button() == input_button::left()) { // Access the value of the left mouse button. auto left_button = mouse_button{static_cast<button>((int)state.is_pressed(mouse_button::left_button))}; // Display the value of the left mouse button. std::cout << "Left mouse button (" << (int)left_button << ") was clicked."<< std::endl; } else { std::cout << "Unknown mouse button was clicked."<< std::endl; } } }通过以上步骤，即可在D编程语言和Tango中获取单键击中的信息。
2. 在窗口或者窗口部件中捕获点击事件并获取单键信息。在窗口或者窗口部件的布局函数中添加以下代码：
3. 处理捕获到的点击事件。在接收器函数中获取单击事件的信息，通过判断单击的事件类型来获取捕获到的键值。具体代码如下：
