Constructor Detail

public Win32Lib()

Method Detail

CoInitializeEx

public static long CoInitializeEx(int coinit)

Initializes the COM subsystem for this thread. If we do more COM stuff then we might have to be smarter about this, and the single-threaded model could lead to problems.

Returns:

the HRESULT of the call to CoInitialize().

CreateWindow

public static long CreateWindow(java.lang.String className,
                                java.lang.String windowName,
                                long style,
                                int x,
                                int y,
                                int width,
                                int height,
                                long parentWindow,
                                long menu,
                                long hinstance,
                                long lparam)

Creates a native Windows window.

Parameters:

className -

windowName -

style -

x -

y -

width -

height -

parentWindow -

menu -

hinstance -

lparam -

Returns:

the HWND of the native window, or 0 if the call failed.

DestroyWindow

public static boolean DestroyWindow(long hwnd)

DispatchMessage

public static long DispatchMessage(Win32Lib.MSG msg)

GetLastError

public static long GetLastError()

Always seems to return 0. I might take it out.

Returns:

the last error, or possibly always 0.

GetMessage

public static boolean GetMessage(Win32Lib.MSG msg,
                                 long hwnd,
                                 long msgFilterMin,
                                 long msgFilterMax)

GetModuleHandle

public static long GetModuleHandle(java.lang.String moduleName)

GetProcAddress

public static long GetProcAddress(long library,
                                  java.lang.String procName)

LoadLibrary

public static long LoadLibrary(java.lang.String moduleName)

PeekMessage

public static boolean PeekMessage(Win32Lib.MSG msg,
                                  long hwnd,
                                  long msgFilterMin,
                                  long msgFilterMax,
                                  long removeMessage)

checkNativeLibrary

public static boolean checkNativeLibrary()

Lazily loads the native library and returns success or failure. Only tries to load the library once; subsequent calls return the success or failure of the first call.
