This will make some actions such as moving the window work |

better. |
| 100 |
|

The event handler should look like: |

void process_xevent(XEvent *ev) { } |

| 104 |
To install it: |
| 105 |
W11AddEventHandler(display,process_xevent); |

|
| 107 |
The specific problem is that calling DefWindowProc() |
| 108 |
in response to a WM_SYSCOMMAND will cause windows to run its |
| 109 |
own event loop waiting for the mouse up event. The application |
| 110 |
therefore cannot rely on it's main event loop to get run for |
| 111 |
each event. Without running multiple threads, or setjmp, there |
| 112 |
is little recourse for alerting the application in the |
| 113 |
traditional X manner to Expose events while the window is |
| 114 |
being moved. |

Comments: Windows routines receive messages (events) in two ways: |
| 860 |
firstly by GetMessage, which takes messages from the |

calling thread's message queue, and secondly by the |
| 862 |
window function being called with events as arguments. |
| 863 |
To simulate the X system, we get messages from the queue |
| 864 |
and pass them to the window function anyway, which |
| 865 |
processes them and fills out the local XEvent structure. |
| 866 |
DispatchMessage calls the window procedure and waits until |
| 867 |
it returns. Translate message turns WM_KEYUP/DOWN messages |
| 868 |
into WM_CHAR. |
