+
+    @remarks
+    This control provides access to its internal components (e.g., GetNewButton(),
+    GetListCtrl()) for advanced customization.
+
+    You may bind events directly to these internal buttons (e.g., @c wxEVT_BUTTON)
+    to intercept or augment default behavior. To add custom validation before
+    an action occurs, bind to the button and call `event.Skip()` only if
+    validation passes. To completely override the default behavior,
+    omit the call to `event.Skip()`.
