    copied!<p>I have a collection of related classes, call them</p> <pre><code>class Manager { private: std::vector&lt;Setting&gt; m_settings; } class Setting { private: std::vector&lt;Action&gt; m_actions; } class Action { private: Keybind m_keybind; } class Keybind { public: UpdateKeybind; private: TYPE keybind; } </code></pre> <p>As you can see from the pseudo-C++ code, Settings have actions, and actions have exactly one key binding. Now, as a user of my application you want to update the Keybind potentially, yes?</p> <p>I currently have buttons in a keybind-type dialog associated with each action, so the action can handle updating it's own keybind.</p> <p><strong>My Problem</strong>: </p> <p>How do I ensure that the Keybinding isn't bound to another object?</p> <p><strong>Possible solutions</strong>: </p> <ol> <li>Move UpdateKeybind itself to the Manager class, then have Manager query all the settings.</li> <li>Have a parent pointer in Action/Setting/Keybind so the Action can query the manager for updated keybind. </li> <li>Have the Action query other Actions (not great conceptually as far as I can tell).</li> </ol> <p><strong>What I need from you</strong>:</p> <ol> <li><p>What is the most rigorous approach, in terms of maintainability, speed, ease of understanding, and OOP appropriateness, to implementing checking if a Keybind is already found, whether out of my suggested solutions or something else entirely. I have already tried number 1 -- it works, but I feel like it could be better, ya dig? I was unable to find similar questions on StackOverflow, but if you do I'd love to see them!</p></li> <li><p>Any other pro tips, things to improve are helpful.</p></li> </ol>
