Method Detail

getCurrentPlatformID

public static PlatformID getCurrentPlatformID()

Returns a PlatformID describing the current platform

---

addPlatformListener

public static void addPlatformListener(PlatformListener listener)

Add a listener for platform events

---

removePlatformListener

public static void removePlatformListener(PlatformListener listener)

Remove a listener for platform events

---

firePlatformEvent

public static void firePlatformEvent(PlatformEvent event)

Fire a platform event

---

initPlatformProviders

private static void initPlatformProviders()

---

getNamedPlatformProvider

public static PlatformProvider getNamedPlatformProvider(java.lang.String name)

Returns the platform provider with the given name if it is available, or null if it is not. Note that even if we're running on that platform, this may still return null if the platform provider wasn't compiled in by whoever built this program-- in such a case, functionality specific to that platform will still not be available.

---

isUsingMacOSXScreenMenuBar

public static boolean isUsingMacOSXScreenMenuBar()

Returns true if swing menu bars are currently being merged into the Mac OS X screen-wide menu bar. If this is the case, a system menu is present that automatically provides "About", "Preferences" and "Quit" items, among others. In this case, the program should generally not provide those facilities itself.

---

isSystemPreferencesMenuItemEnabled

public static boolean isSystemPreferencesMenuItemEnabled()

Returns true if there is a system-provided "Preferences" menu item and it is enabled.

---

setSystemPreferencesMenuItemEnabled

public static boolean setSystemPreferencesMenuItemEnabled(boolean enabled)

Enable or disable the system-provided "Preferences" menu item.
