+/**
+    @class wxDPIChangedEvent
+
+    Event sent when the resolution (measured in dots-per-inch, or DPI) of the
+    monitor a window is on changes.
+
+    The event is sent to each wxTopLevelWindow affected by the change, and all
+    its children recursively. For example, this event is sent to the window
+    when it is moved, by the user, from a display using some DPI value to
+    another display using a different DPI value. It also sent to all program
+    windows on the given display if its DPI changes due to a change in the
+    system settings.
+
+    Currently this event is generated by wxMSW port if only and only if the
+    MSW application runs under Windows 10 Creators Update (v1703) or later and
+    is marked as being "per-monitor DPI aware", i.e. contains a @c dpiAwareness
+    tag with the value "PerMonitorV2" in its manifest (see Microsoft
+    <a href="https://docs.microsoft.com/en-us/windows/desktop/sbscs/application-manifests">"Application Manifests" documentation</a>
+    for more details).
+
+    @note Per-monitor DPI support is an experimental feature that is still in
+    development. It might not work correctly for some controls.
