This is what I've got so far:
' hWnd needs to be set before initializing the event handler.
' You can get this value with hWnd = GetActiveWindow(), or with hWnd = QueryGadget(Window, QUERY_HWND), where Window is your window's gadget pointer. (May require MaxGUI)
Global hWnd:Int
Global OldWinProc:Int
OldWinProc = SetWindowLongPtr(hWnd, GWL_WNDPROC, WinProc)
Function WinProc%(hWnd:Int, Msg:Int, wParam:Int, lParam:Int) "win32"
Select Msg
Case WM_RESIZE
DebugLog("WM_RESIZE")
Case WM_MOVE
DebugLog("WM_MOVE")
Case WM_CLOSE
DebugLog("WM_CLOSE")
Case WM_DESTROY
DebugLog("WM_DESTROY")
' Restore old winproc.
SetWindowLong(hwnd, GWL_WNDPROC, OldWinProc)
Case WM_KEYDOWN
DebugLog("WM_KEYDOWN")
DebugLog("You pressed: " + Chr$(wParam))
Case WM_CREATE
DebugLog("WM_CREATE")
Case WM_INITDIALOG
DebugLog("WM_INITDIALOG")
Case WM_COMMAND
DebugLog("WM_COMMAND " + lParam)
Case WM_INPUT
dwSize:Int = 40
lpb:Byte[40]
GetRawInputData((HRAWINPUT)lParam, RID_INPUT, lpb, &dwSize, SizeOf(RAWINPUTHEADER));
RAWINPUT* raw = (RAWINPUT*)lpb;
If (raw->header.dwType == RIM_TYPEMOUSE)
Int xPosRelative = raw->data.mouse.lLastX;
Int yPosRelative = raw->data.mouse.lLastY;
EndIf
Default
'DebugLog Msg
End Select
If OldWinProc <> 0 Then Return CallWindowProc(OldWinProc, hWnd, Msg, wParam, lParam)
End Function
Function LOWORD(value)
Return value & $FFFF
End Function
Function HIWORD(value)
Return (value Shr 16)
End Function
Type RAWINPUTDEVICE
Field usUsagePage:Short
Field usUsage:Short
Field dwFlags:Int
Field hwndTarget:Int
End Type
Const HID_USAGE_PAGE_GENERIC = $1
Const HID_USAGE_GENERIC_MOUSE = $2
Const RIDEV_INPUTSINK = $100
Global Rid:RAWINPUTDEVICE[1]
Rid[0].usUsagePage = HID_USAGE_PAGE_GENERIC
Rid[0].usUsage = HID_USAGE_GENERIC_MOUSE
Rid[0].dwFlags = RIDEV_INPUTSINK
Rid[0].hwndTarget = hWnd ' hWnd needs to be set by the time we get here, so this should be in an init function.
RegisterRawInputDevices(Rid, 1, SizeOf(Rid[0])
Extern "Win32"
Function RegisterRawInputDevices:Int(pRawInputDevices:Byte Ptr, uiNumDevices:Int, cbSize:Int)
Function GetRawInputData:Int(HRAWINPUT hRawInput, uiCommand:Int, LPVOID pData, PUINT pcbSize, cbSizeHeader:Int)
End Extern
Where I'm currently stuck is declaring that second extern at the bottomn. Then I need to figure out what that C code in the WM_INPUT event is doing...
