/*
 * testtray - SDL system tray API test application
 *
 * This program creates two system tray icons to demonstrate and test the
 * SDL tray API:
 *
 * 1. Control tray (sdl-test_round.png) - Provides a menu to:
 *    - Quit: Exit the application
 *    - Destroy trays: Remove both tray icons and show the window
 *    - Hide/Show window: Toggle the window visibility
 *    - Change icon: Change the example tray's icon via file dialog
 *    - Create button/checkbox/submenu/separator: Add menu items to the
 *      example tray, demonstrating dynamic menu construction
 *
 * 2. Example tray (speaker.png) - A target tray that can be manipulated
 *    through the control tray's menu. Menu items created here can be
 *    enabled, disabled, checked, unchecked, or removed via submenus that
 *    appear in the control tray. This tray is created with
 *    SDL_CreateTrayWithProperties to demonstrate click callbacks:
 *    - Left click: Logs a message and shows the menu (returns true)
 *    - Right click: Logs a message and suppresses the menu (returns false)
 *    - Middle click: Logs a message (menu never shows for middle click)
 *
 * Window behavior:
 * - Closing the window (X button) hides it to the tray rather than exiting
 * - The "Hide/Show window" menu item toggles visibility and updates its label
 * - If trays are destroyed while the window is hidden, it is shown first
 * - If trays are destroyed, closing the window exits the application
