| 39 | ** File: winevent.c
|
|---|
| 40 | ** Description: Test functions in plevent.c using Windows
|
|---|
| 41 | **
|
|---|
| 42 | ** The winevent test exercises the PLEvent library in a maner
|
|---|
| 43 | ** similar to how the Mozilla (or NGLayout) Client will use
|
|---|
| 44 | ** it in a Windows environment.
|
|---|
| 45 | **
|
|---|
| 46 | ** This test is based on ideas taken from Charles Petzold's
|
|---|
| 47 | ** book "Programming Windows 3.1". License to use is in the
|
|---|
| 48 | ** book. It has been ported to Win32.
|
|---|
| 49 | **
|
|---|
| 50 | ** Operation:
|
|---|
| 51 | ** The initialization is a standard Windows GUI application
|
|---|
| 52 | ** setup. When the main window receives its WM_CREATE
|
|---|
| 53 | ** message, a child window is created, a edit control is
|
|---|
| 54 | ** instantiated in that window.
|
|---|
| 55 | **
|
|---|
| 56 | ** A thread is created; this thread runs in the function:
|
|---|
| 57 | ** TimerThread(). The new thread sends a message every second
|
|---|
| 58 | ** via the PL_PostEvent() function. The event handler
|
|---|
| 59 | ** HandlePadEvent() sends a windows message to the edit
|
|---|
| 60 | ** control window; these messages are WM_CHAR messages that
|
|---|
| 61 | ** cause the edit control to place a single '.' character in
|
|---|
| 62 | ** the edit control.
|
|---|
| 63 | **
|
|---|
| 64 | ** After a deterministic number of '.' characters, the
|
|---|
| 65 | ** TimerThread() function is notified via a global variable
|
|---|
| 66 | ** that it's quitting time.
|
|---|
| 67 | **
|
|---|
| 68 | ** TimerThread() callse TestEvents(), an external function
|
|---|
| 69 | ** that tests additional function of PLEvent.
|
|---|
