```
Creates an overlapped, pop-up, or child window with an extended window style; otherwise, this function is identical to the CreateWindow function.

Parameters:

dwExStyle - the extended window style of the window being created

lpClassName - a null-terminated string or a class atom created by a previous call to the User32.RegisterClassEx(WNDCLASSEX) function.

lpWindowName - the window name. If the window style specifies a title bar, the window title pointed to by lpWindowName is displayed in the title bar.

dwStyle - the style of the window being created

x - the initial horizontal position of the window

y - the initial vertical position of the window

nWidth - the width, in device units, of the window

nHeight - the height, in device units, of the window

hWndParent - a handle to the parent or owner window of the window being created. To create a child window or an owned window, supply a valid window handle.

hMenu - a handle to a menu, or specifies a child-window identifier, depending on the window style

hInstance - a handle to the instance of the module to be associated with the window

lpParam - a value to be passed to the window through the CREATESTRUCT structure (createParams member) pointed to by the lParam param of the User32.WM_CREATE message.

DestroyWindow
```
public static boolean DestroyWindow(long hWnd)
```
Destroys the specified window. The function sends User32.WM_DESTROY and User32.WM_NCDESTROY messages to the window to deactivate it and remove the keyboard focus from it. The function also destroys the window's menu, flushes the thread message queue, destroys timers, removes clipboard ownership, and breaks the clipboard viewer chain (if the window is at the top of the viewer chain).
If the specified window is a parent or owner window, DestroyWindow automatically destroys the associated child or owned windows when it destroys the parent or owner window. The function first destroys child or owned windows, and then it destroys the parent or owner window.

Parameters:

hWnd - a handle to the window to be destroyed

DefWindowProc
```
public static long DefWindowProc(long hWnd,
                                 int Msg,
                                 long wParam,
                                 long lParam)
```
Calls the default window procedure to provide default processing for any window messages that an application does not process. This function ensures that every message is processed. DefWindowProc is called with the same parameters received by the window procedure.

Parameters:

hWnd - a handle to the window that received the message

Msg - the message

wParam - additional message information. The content of this parameter depends on the value of the Msg parameter.

lParam - additional message information. The content of this parameter depends on the value of the Msg parameter.

ShowWindow

public static boolean ShowWindow(long hWnd,
                                 int nCmdShow)

Sets the specified window's show state.

Parameters:

hWnd - a handle to the window

nCmdShow - controls how the window is to be shown. This parameter is ignored the first time an application calls ShowWindow, if the program that launched the application provides a STARTUPINFO structure. Otherwise, the first time ShowWindow is called, the value should be the value obtained by the WinMain function in its nCmdShow parameter. In subsequent calls, this parameter can be one of:

`User32.SW_HIDE`	`User32.SW_SHOWNORMAL`	`User32.SW_NORMAL`	`User32.SW_SHOWMINIMIZED`	`User32.SW_SHOWMAXIMIZED`	`User32.SW_MAXIMIZE`
`User32.SW_SHOWNOACTIVATE`	`User32.SW_SHOW`	`User32.SW_MINIMIZE`	`User32.SW_SHOWMINNOACTIVE`	`User32.SW_SHOWNA`	`User32.SW_RESTORE`
`User32.SW_SHOWDEFAULT`	`User32.SW_FORCEMINIMIZE`	`User32.SW_MAX`

UpdateWindow
```
public static boolean UpdateWindow(long hWnd)
```
Updates the client area of the specified window by sending a User32.WM_PAINT message to the window if the window's update region is not empty. The function sends a User32.WM_PAINT message directly to the window procedure of the specified window, bypassing the application queue. If the update region is empty, no message is sent.

Parameters:

hWnd - handle to the window to be updated

SetWindowPos

public static boolean SetWindowPos(long hWnd,
                                   long hWndInsertAfter,

GetMessage
```
public static boolean GetMessage(MSG lpMsg,
                                 long hWnd,
                                 int wMsgFilterMin,
                                 int wMsgFilterMax)
```
Retrieves a message from the calling thread's message queue. The function dispatches incoming sent messages until a posted message is available for retrieval. Unlike GetMessage, the User32.PeekMessage(org.lwjgl.system.windows.MSG, long, int, int, int) function does not wait for a message to be posted before returning.

Parameters:

lpMsg - a pointer to an MSG structure that receives message information from the thread's message queue

hWnd - a handle to the window whose messages are to be retrieved. The window must belong to the current thread.
If hWnd is NULL, GetMessage retrieves messages for any window that belongs to the current thread, and any messages on the current thread's message queue whose hwnd value is NULL (see the MSG structure). Therefore if hWnd is NULL, both window messages and thread messages are processed.

If hWnd is -1, GetMessage retrieves only messages on the current thread's message queue whose hwnd value is NULL, that is, thread messages as posted by User32.PostMessage(long, int, long, long) (when the hWnd parameter is NULL) or PostThreadMessage.

wMsgFilterMin - the integer value of the lowest message value to be retrieved

wMsgFilterMax - the integer value of the highest message value to be retrieved

PeekMessage
```
public static boolean PeekMessage(MSG lpMsg,
                                  long hWnd,
                                  int wMsgFilterMin,
                                  int wMsgFilterMax,
                                  int wRemoveMsg)
```
Dispatches incoming sent messages, checks the thread message queue for a posted message, and retrieves the message (if any exist).

Parameters:

lpMsg - a pointer to an MSG structure that receives message information

hWnd - a handle to the window whose messages are to be retrieved. The window must belong to the current thread.
If hWnd is NULL, GetMessage retrieves messages for any window that belongs to the current thread, and any messages on the current thread's message queue whose hwnd value is NULL (see the MSG structure). Therefore if hWnd is NULL, both window messages and thread messages are processed.

If hWnd is -1, GetMessage retrieves only messages on the current thread's message queue whose hwnd value is NULL, that is, thread messages as posted by User32.PostMessage(long, int, long, long) (when the hWnd parameter is NULL) or PostThreadMessage.

wMsgFilterMin - the integer value of the lowest message value to be retrieved

wMsgFilterMax - the integer value of the highest message value to be retrieved

wRemoveMsg - specifies how messages are to be handled. One of:
User32.PM_NOREMOVE User32.PM_REMOVE User32.PM_NOYIELD

TranslateMessage
```
public static boolean TranslateMessage(MSG lpMsg)
```
Translates virtual-key messages into character messages. The character messages are posted to the calling thread's message queue, to be read the next time the thread calls the User32.GetMessage(org.lwjgl.system.windows.MSG, long, int, int) or User32.PeekMessage(org.lwjgl.system.windows.MSG, long, int, int, int) function.

Parameters:

lpMsg - an MSG structure that contains message information retrieved from the calling thread's message queue by using the User32.GetMessage(org.lwjgl.system.windows.MSG, long, int, int) or User32.PeekMessage(org.lwjgl.system.windows.MSG, long, int, int, int) function.

WaitMessage
```
public static boolean WaitMessage()
```
Yields control to other threads when a thread has no other messages in its message queue. The WaitMessage function suspends the thread and does not return until a new message is placed in the thread's message queue.

DispatchMessage
```
public static long DispatchMessage(MSG lpmsg)
```
Dispatches a message to a window procedure. It is typically used to dispatch a message retrieved by the User32.GetMessage(org.lwjgl.system.windows.MSG, long, int, int) function.

Parameters:

lpmsg - a pointer to a structure that contains the message.

nPostMessageW

public static int nPostMessageW(long __functionAddress,

                                  long lParam)
```
Places (posts) a message in the message queue associated with the thread that created the specified window and returns without waiting for the thread to process the message.
Parameters:
hWnd - a handle to the window whose window procedure is to receive the message. The following values have special meanings:
- User32.HWND_BROADCAST - The message is posted to all top-level windows in the system, including disabled or invisible unowned windows, overlapped windows, and pop-up windows. The message is not posted to child windows.
- NULL - The function behaves like a call to PostThreadMessage with the dwThreadId parameter set to the identifier of the current thread.
Msg - the message to be posted

wParam - additional message-specific information

lParam - additional message-specific information

nSendMessageW

                                  long wParam,
                                  long lParam)
```
Sends the specified message to a window or windows. The SendMessage function calls the window procedure for the specified window and does not return until the window procedure has processed the message.

Parameters:

hWnd - a handle to the window whose window procedure will receive the message. If this parameter is User32.HWND_BROADCAST, the message is sent to all top-level windows in the system, including disabled or invisible unowned windows, overlapped windows, and pop-up windows; but the message is not sent to child windows.
Message sending is subject to UIPI. The thread of a process can send messages only to message queues of threads in processes of lesser or equal integrity level.

Msg - the message to be sent

wParam - additional message-specific information

lParam - additional message-specific information

GetDC
```
public static long GetDC(long hWnd)
```
Retrieves a handle to a device context (DC) for the client area of a specified window or for the entire screen. You can use the returned handle in subsequent GDI functions to draw in the DC. The device context is an opaque data structure, whose values are used internally by GDI.

Parameters:

hWnd - a handle to the window whose DC is to be retrieved. If this value is NULL, GetDC retrieves the DC for the entire screen.

ReleaseDC
```
public static boolean ReleaseDC(long hWnd,
                                long hDC)

RegisterTouchWindow
```
public static boolean RegisterTouchWindow(long hWnd,
                                          int ulFlags)
```
Registers a window as being touch-capable.
RegisterTouchWindow must be called on every window that will be used for touch input. This means that if you have an application that has multiple windows within it, RegisterTouchWindow must be called on every window in that application that uses touch features. Also, an application can call RegisterTouchWindow any number of times for the same window if it desires to change the modifier flags. A window can be marked as no longer requiring touch input using the User32.UnregisterTouchWindow(long) function.

Parameters:

hWnd - the handle of the window being registered. The function fails with ERROR_ACCESS_DENIED if the calling thread does not own the specified window.

ulFlags - a set of bit flags that specify optional modifications. This field may contain 0 or one or more of:
User32.TWF_FINETOUCH User32.TWF_WANTPALM

Since:

Windows 7 (desktop apps only)

UnregisterTouchWindow
```
public static boolean UnregisterTouchWindow(long hWnd)
```
Registers a window as no longer being touch-capable.

Parameters:

hWnd - the handle of the window. The function fails with ERROR_ACCESS_DENIED if the calling thread does not own the specified window.

Since:

Windows 7 (desktop apps only)

IsTouchWindow
```
public static boolean IsTouchWindow(long hWnd,
                                    java.nio.IntBuffer pulFlags)
```
Checks whether a specified window is touch-capable and, optionally, retrieves the modifier flags set for the window's touch capability.

Parameters:

hWnd - the handle of the window. The function fails with ERROR_ACCESS_DENIED if the calling thread is not on the same desktop as the specified window.

pulFlags - an optional address of the ULONG variable to receive the modifier flags for the specified window's touch capability.

Since:

Windows 7 (desktop apps only)

GetTouchInputInfo
```
public static boolean GetTouchInputInfo(long hTouchInput,
                                        TOUCHINPUT.Buffer pInputs,
                                        int cbSize)
```
Retrieves detailed information about touch inputs associated with a particular touch input handle.

Parameters:

hTouchInput - the touch input handle received in the LPARAM of a touch message. The function fails with ERROR_INVALID_HANDLE if this handle is not valid. Note that the handle is not valid after it has been used in a successful call to User32.CloseTouchInputHandle(long) or after it has been passed to User32.DefWindowProc(long, int, long, long), User32.PostMessage(long, int, long, long), User32.SendMessage(long, int, long, long) or one of their variants.

pInputs - a pointer to an array of TOUCHINPUT structures to receive information about the touch points associated with the specified touch input handle

cbSize - the size, in bytes, of a single TOUCHINPUT structure. If cbSize is not the size of a single TOUCHINPUT structure, the function fails with ERROR_INVALID_PARAMETER.

Since:

Windows 7 (desktop apps only)

CloseTouchInputHandle
```
public static boolean CloseTouchInputHandle(long hTouchInput)
```
Closes a touch input handle, frees process memory associated with it, and invalidates the handle.

Parameters:

hTouchInput - the touch input handle received in the LPARAM of a touch message. The function fails with ERROR_INVALID_HANDLE if this handle is not valid. Note that the handle is not valid after it has been used in a successful call to User32.CloseTouchInputHandle(long) or after it has been passed to User32.DefWindowProc(long, int, long, long), User32.PostMessage(long, int, long, long), User32.SendMessage(long, int, long, long) or one of their variants.

MonitorFromWindow
```
public static long MonitorFromWindow(long hWnd,
                                     int dwFlags)
```
Retrieves a handle to the display monitor that has the largest area of intersection with the bounding rectangle of a specified window.

Parameters:

hWnd - a handle to the window of interest

dwFlags - determines the function's return value if the window does not intersect any display monitor. One of:
User32.MONITOR_DEFAULTTONULL User32.MONITOR_DEFAULTTOPRIMARY User32.MONITOR_DEFAULTTONEAREST

GetMonitorInfo
```
public static boolean GetMonitorInfo(long hMonitor,
                                     MONITORINFOEX lpmi)
```
Retrieves information about a display monitor.

Parameters:

hMonitor - a handle to the display monitor of interest

lpmi - a pointer to a MONITORINFOEX structure that receives information about the specified display monitor.
You must set the cbSize member of the structure to MONITORINFOEX.SIZEOF before calling the GetMonitorInfo function. Doing so lets the function determine the type of structure you are passing to it.

EnumDisplayDevices
```
public static boolean EnumDisplayDevices(java.nio.ByteBuffer lpDevice,
                                         int iDevNum,
                                         DISPLAY_DEVICE lpDisplayDevice,
                                         int dwFlags)

public static boolean EnumDisplayDevices(java.lang.CharSequence lpDevice,
                                         int iDevNum,
                                         DISPLAY_DEVICE lpDisplayDevice,
                                         int dwFlags)
```
Obtains information about the display devices in the current session.

Parameters:

lpDevice - the device name. If NULL, function returns information for the display adapter(s) on the machine, based on devNum.

iDevNum - an index value that specifies the display device of interest.
The operating system identifies each display device in the current session with an index value. The index values are consecutive integers, starting at 0. If the current session has three display devices, for example, they are specified by the index values 0, 1, and 2.

lpDisplayDevice - a pointer to a DISPLAY_DEVICE structure that receives information about the display device specified by iDevNum.
Before calling EnumDisplayDevices, you must initialize the cb member of DISPLAY_DEVICE to the size, in bytes, of DISPLAY_DEVICE.

dwFlags - set this flag to User32.EDD_GET_DEVICE_INTERFACE_NAME to retrieve the device interface name for GUID_DEVINTERFACE_MONITOR, which is registered by the operating system on a per monitor basis. The value is placed in the DeviceID member of the DISPLAY_DEVICE structure returned in lpDisplayDevice. The resulting device interface name can be used with SetupAPI functions and serves as a link between GDI monitor devices and SetupAPI monitor devices.

EnumDisplaySettingsEx
```
public static boolean EnumDisplaySettingsEx(java.nio.ByteBuffer lpszDeviceName,
                                            int iModeNum,
                                            DEVMODE lpDevMode,
                                            int dwFlags)

public static boolean EnumDisplaySettingsEx(java.lang.CharSequence lpszDeviceName,
                                            int iModeNum,
                                            DEVMODE lpDevMode,
                                            int dwFlags)
```
Retrieves information about one of the graphics modes for a display device. To retrieve information for all the graphics modes for a display device, make a series of calls to this function.

Parameters:

lpszDeviceName - a pointer to a null-terminated string that specifies the display device about which graphics mode the function will obtain information.
This parameter is either NULL or a DISPLAY_DEVICE.DeviceName() returned from User32.EnumDisplayDevices(java.nio.ByteBuffer, int, org.lwjgl.system.windows.DISPLAY_DEVICE, int). A NULL value specifies the current display device on the computer that the calling thread is running on.

iModeNum - indicates the type of information to be retrieved.
Graphics mode indexes start at zero. To obtain information for all of a display device's graphics modes, make a series of calls to EnumDisplaySettingsEx, as follows: Set iModeNum to zero for the first call, and increment iModeNum by one for each subsequent call. Continue calling the function until the return value is zero.

When you call EnumDisplaySettingsEx with iModeNum set to zero, the operating system initializes and caches information about the display device. When you call EnumDisplaySettingsEx with iModeNum set to a nonzero value, the function returns the information that was cached the last time the function was called with iModeNum set to zero.

This value can be a graphics mode index or one of:
User32.ENUM_CURRENT_SETTINGS User32.ENUM_REGISTRY_SETTINGS

lpDevMode - a pointer to a DEVMODE structure into which the function stores information about the specified graphics mode. Before calling EnumDisplaySettingsEx, set the dmSize member to DEVMODE.SIZEOF, and set the dmDriverExtra member to indicate the size, in bytes, of the additional space available to receive private driver data.
The EnumDisplaySettingsEx function will populate the dmFields member of the lpDevMode and one or more other members of the DEVMODE structure. To determine which members were set by the call to EnumDisplaySettingsEx, inspect the dmFields bitmask.

dwFlags - this parameter can be one of:
User32.EDS_RAWMODE User32.EDS_ROTATEDMODE

ChangeDisplaySettingsEx

public static int ChangeDisplaySettingsEx(java.nio.ByteBuffer lpszDeviceName,
                                          DEVMODE lpDevMode,
                                          long hwnd,
                                          int dwflags,
                                          long lParam)

public static int ChangeDisplaySettingsEx(java.lang.CharSequence lpszDeviceName,
                                          DEVMODE lpDevMode,
                                          long hwnd,
                                          int dwflags,
                                          long lParam)

Changes the settings of the specified display device to the specified graphics mode.

Parameters:

lpszDeviceName - a pointer to a null-terminated string that specifies the display device whose graphics mode will change. Only display device names as returned by User32.EnumDisplayDevices(java.nio.ByteBuffer, int, org.lwjgl.system.windows.DISPLAY_DEVICE, int) are valid.

The lpszDeviceName parameter can be NULL. A NULL value specifies the default display device. The default device can be determined by calling EnumDisplayDevices and checking for the GDI32.DISPLAY_DEVICE_PRIMARY_DEVICE flag.

lpDevMode - a pointer to a DEVMODE structure that describes the new graphics mode. If lpDevMode is NULL, all the values currently in the registry will be used for the display setting. Passing NULL for the lpDevMode parameter and 0 for the dwFlags parameter is the easiest way to return to the default mode after a dynamic mode change.

The dmSize member must be initialized to the size, in bytes, of the DEVMODE structure. The dmDriverExtra member must be initialized to indicate the number of bytes of private driver data following the DEVMODE structure.

hwnd - reserved; must be NULL

dwflags - indicates how the graphics mode should be changed. One of:

`User32.CDS_UPDATEREGISTRY`	`User32.CDS_TEST`	`User32.CDS_FULLSCREEN`	`User32.CDS_GLOBAL`	`User32.CDS_SET_PRIMARY`
`User32.CDS_VIDEOPARAMETERS`	`User32.CDS_ENABLE_UNSAFE_MODES`	`User32.CDS_DISABLE_UNSAFE_MODES`	`User32.CDS_RESET`	`User32.CDS_RESET_EX`
`User32.CDS_NORESET`

lParam - if flags is User32.CDS_VIDEOPARAMETERS, lParam is a pointer to a VIDEOPARAMETERS structure. Otherwise lParam must be NULL.

Returns:

one of the following values: User32.DISP_CHANGE_SUCCESSFUL User32.DISP_CHANGE_RESTART User32.DISP_CHANGE_FAILED User32.DISP_CHANGE_BADMODE User32.DISP_CHANGE_NOTUPDATED User32.DISP_CHANGE_BADFLAGS User32.DISP_CHANGE_BADPARAM User32.DISP_CHANGE_BADDUALVIEW

GetCursorPos
```
public static boolean GetCursorPos(POINT point)
```
Retrieves the position of the mouse cursor, in screen coordinates.

Parameters:

point - a pointer to a POINT structure that receives the screen coordinates of the cursor

SetCursorPos
```
public static boolean SetCursorPos(int X,
                                   int Y)
```
Moves the cursor to the specified screen coordinates. If the new coordinates are not within the screen rectangle set by the most recent User32.ClipCursor(org.lwjgl.system.windows.RECT) function call, the system automatically adjusts the coordinates so that the cursor stays within the rectangle.

Parameters:

X - the new x-coordinate of the cursor, in screen coordinates.

Y - the new y-coordinate of the cursor, in screen coordinates.

ClipCursor
```
public static boolean ClipCursor(RECT rect)
```
Confines the cursor to a rectangular area on the screen. If a subsequent cursor position (set by the User32.SetCursorPos(int, int) function or the mouse) lies outside the rectangle, the system automatically adjusts the position to keep the cursor inside the rectangular area.

Parameters:

rect - a pointer to the structure that contains the screen coordinates of the upper-left and lower-right corners of the confining rectangle. If this parameter is NULL, the cursor is free to move anywhere on the screen.

ShowCursor
```
public static int ShowCursor(boolean show)
```
Displays or hides the cursor.
This function sets an internal display counter that determines whether the cursor should be displayed. The cursor is displayed only if the display count is greater than or equal to 0. If a mouse is installed, the initial display count is 0. If no mouse is installed, the display count is –1.

Parameters:

show - If show is WinBase.TRUE, the display count is incremented by one. If show is WinBase.FALSE, the display count is decremented by one.

Returns:

the new display counter

SetCursor
```
public static long SetCursor(long hCursor)
```
Sets the cursor shape.
The cursor is set only if the new cursor is different from the previous cursor; otherwise, the function returns immediately.

The cursor is a shared resource. A window should set the cursor shape only when the cursor is in its client area or when the window is capturing mouse input. In systems without a mouse, the window should restore the previous cursor before the cursor leaves the client area or before it relinquishes control to another window.

If your application must set the cursor while it is in a window, make sure the class cursor for the specified window's class is set to NULL. If the class cursor is not NULL, the system restores the class cursor each time the mouse is moved.

The cursor is not shown on the screen if the internal cursor display count is less than zero. This occurs if the application uses the User32.ShowCursor(boolean) function to hide the cursor more times than to show the cursor.

Parameters:

hCursor - a handle to the cursor. The cursor must have been created by the CreateCursor function or loaded by the User32.LoadCursor(long, java.nio.ByteBuffer) or LoadImage function. If this parameter is NULL, the cursor is removed from the screen.

Returns:

the handle to the previous cursor, if there was one
