<modulesummary>Functions for wxNotificationMessage class</modulesummary>
<description><p>This class allows showing the user a message non intrusively.
</p><p>Currently it is implemented natively for Windows, macOS, GTK and uses generic toast notifications under the other platforms. It's not recommended but <c>wxGenericNotificationMessage</c> can be used instead of the native ones. This might make sense if your application requires features not available in the native implementation.
</p><p>Notice that this class is not a window and so doesn't derive from <seeerl marker="wxWindow"><c>wxWindow</c></seeerl>.
</p><p>Platform Notes</p> <p>Par: Up to Windows 8 balloon notifications are displayed from an icon in the notification area of the taskbar. If your application uses a <seeerl marker="wxTaskBarIcon"><c>wxTaskBarIcon</c></seeerl> you should call <seemfa marker="#useTaskBarIcon/1"><c>useTaskBarIcon/1</c></seemfa> to ensure that only one icon is shown in the notification area. Windows 10 displays all notifications as popup toasts. To suppress the additional icon in the notification area on Windows 10 and for toast notification support on Windows 8 it is recommended to call <seemfa marker="#mSWUseToasts/1"><c>mSWUseToasts/1</c></seemfa> before showing the first notification message.
</p><p>Par: The macOS implementation uses Notification Center to display native notifications. In order to use actions your notifications must use the alert style. This can be enabled by the user in system settings or by setting the <c>NSUserNotificationAlertStyle</c> value in Info.plist to <c>alert</c>. Please note that the user always has the option to change the notification style.
</p><p>Since: 2.9.0
</p>
<p>This class is derived (and can use functions) from:
<seeerl marker="wxEvtHandler"><c>wxEvtHandler</c></seeerl></p>
