License to use is in the +** book. It has been ported to Win32. +** +** Operation: +** The initialization is a standard Windows GUI application +** setup. When the main window receives its WM_CREATE +** message, a child window is created, a edit control is +** instantiated in that window. +** +** A thread is created; this thread runs in the function: +** TimerThread(). The new thread sends a message every second +** via the PL_PostEvent() function. The event handler +** HandlePadEvent() sends a windows message to the edit +** control window; these messages are WM_CHAR messages that +** cause the edit control to place a single '.' character in +** the edit control. +** +** After a deterministic number of '.' characters, the +** TimerThread() function is notified via a global variable +** that it's quitting time. +** +** TimerThread() callse TestEvents(), an external function +** that tests additional function of PLEvent. +** +*/ + +#include "nspr.h" +#include "plevent.h" + +#include <windows.h> +#include <commdlg.h> + +#define ID_EDIT 1 + +/* +** Declarations for NSPR customization +** +*/ +typedef struct PadEvent +{ + PLEvent plEvent; + int unused; +} PadEvent; + +static void PR_CALLBACK TimerThread( void *arg); +static void PR_CALLBACK HandlePadEvent( PadEvent *padEvent ); +static void PR_CALLBACK DestroyPadEvent( PadEvent *padevent ); + +static PRThread *tThread; +static PLEventQueue *padQueue; +static long ThreadSleepTime = 1000; /* in milli-seconds */ +static long timerCount = 0; +static HWND hDlgModeless ; +static HWND hwndEdit ; +static PRBool testFinished = PR_FALSE; +static HWND hwnd ; + +LRESULT CALLBACK WinProc (HWND, UINT, WPARAM, LPARAM); + +TCHAR appName[] = TEXT ("WinEvent") ; + +int WINAPI WinMain( + HINSTANCE hInstance, + HINSTANCE hPrevInstance, + PSTR szCmdLine, + int iCmdShow + ) +{ + MSG msg ; + WNDCLASS wndclass ; + HANDLE hAccel ; + + PR_Init(0, 0, 0); + + wndclass.style = CS_HREDRAW | CS_VREDRAW; + wndclass.lpfnWndProc = WinProc; + wndclass.cbClsExtra = 0; + wndclass.cbWndExtra = 0; + wndclass.hInstance = hInstance; + wndclass.hIcon = LoadIcon( NULL, IDI_APPLICATION ); + wndclass.hCursor = LoadCursor( NULL, IDC_ARROW ); + wndclass.hbrBackground = (HBRUSH)GetStockObject( WHITE_BRUSH ); + wndclass.lpszMenuName = NULL; + wndclass.lpszClassName = appName; + + if ( !RegisterClass( &wndclass )) + { + MessageBox( NULL, + TEXT( "This program needs Win32" ), + appName, + MB_ICONERROR ); + return 0; + } + + hwnd = CreateWindow( appName, + appName, + WS_OVERLAPPEDWINDOW, + CW_USEDEFAULT, + CW_USEDEFAULT, + CW_USEDEFAULT, + CW_USEDEFAULT, + NULL, + NULL, + hInstance, + NULL); + + ShowWindow( hwnd, iCmdShow ); + UpdateWindow( hwnd ); + + for(;;) + { + if ( PeekMessage( &msg, NULL, 0, 0, PM_NOREMOVE )) + { + if ( GetMessage( &msg, NULL, 0, 0 )) + { + if ( hDlgModeless == NULL || !IsDialogMessage( hDlgModeless, &msg )) + { + if ( !TranslateAccelerator( hwnd, hAccel, &msg )) + { + TranslateMessage( &msg ); + DispatchMessage( &msg ); + } /* end if !TranslateAccelerator */ + } + } + else + { + break; + } /* end if GetMessage() */ + } + else /* !PeekMessage */ + { + PR_Sleep(50); + }/* end if PeekMessage() */ + } /* end for() */ + + PR_JoinThread( tThread ); + PL_DestroyEventQueue( padQueue ); + PR_Cleanup(); + return msg.wParam ; +} + +LRESULT CALLBACK WinProc( + HWND hwnd, + UINT message, + WPARAM wParam, + LPARAM lParam +) +{ + switch (message) + { + case WM_CREATE : + hwndEdit = CreateWindow( + TEXT( "edit" ), + NULL, + WS_CHILD | WS_VISIBLE | WS_HSCROLL | WS_VSCROLL | + WS_BORDER | ES_LEFT | ES_MULTILINE | + ES_AUTOHSCROLL | ES_AUTOVSCROLL, + 0, 0, 0, 0, + hwnd, + (HMENU)ID_EDIT, + ((LPCREATESTRUCT)lParam)->hInstance, + NULL); + + /* Initialize Event Processing for NSPR + ** Retrieve the event queue just created + ** Create the TimerThread + */ + +/* + PL_InitializeEventsLib( "someName" ); + padQueue = PL_GetMainEventQueue(); +*/ + padQueue = PL_CreateEventQueue("MainQueue", PR_GetCurrentThread()); + PR_ASSERT( padQueue != NULL ); + tThread = PR_CreateThread( PR_USER_THREAD, + TimerThread, + NULL, + PR_PRIORITY_NORMAL, + PR_LOCAL_THREAD, + PR_JOINABLE_THREAD, + 0 ); + return 0 ; + + case WM_SETFOCUS : + SetFocus( hwndEdit ); + return 0; + + case WM_SIZE : + MoveWindow( hwndEdit, 0, 0, LOWORD(lParam), HIWORD(lParam), TRUE ); + return 0 ; + + case WM_COMMAND : + if ( LOWORD(wParam) == ID_EDIT ) + if ( HIWORD(wParam ) == EN_ERRSPACE || + HIWORD( wParam ) == EN_MAXTEXT ) + + MessageBox( hwnd, TEXT( "Edit control out of space." ), + appName, MB_OK | MB_ICONSTOP ); + return 0; + + case WM_DESTROY : + PostQuitMessage(0); + return 0; + } + return DefWindowProc( hwnd, message, wParam, lParam ); +} + + + +/* +** TimerThread() -- The Main function of the timer pop thread +** +*/ +static void PR_CALLBACK TimerThread( void *arg ) +{ + PRIntn rc; + + do { + PadEvent *ev; + + /* + ** Create and Post the event the event + */ + PL_ENTER_EVENT_QUEUE_MONITOR( padQueue ); + ev = (PadEvent *) PR_NEW( PadEvent ); + PL_InitEvent( &ev->plEvent, NULL, + (PLHandleEventProc)HandlePadEvent, + (PLDestroyEventProc)DestroyPadEvent ); + PL_PostEvent( padQueue, &ev->plEvent ); + PL_EXIT_EVENT_QUEUE_MONITOR( padQueue ); + + PR_Sleep( PR_MillisecondsToInterval(ThreadSleepTime) ); + } while( testFinished == PR_FALSE ); + + PR_Sleep( PR_SecondsToInterval(4) ); + + /* + ** All done now.
