Re: [PATCH] Fix command line arguments for multiple monitors

[Jörg Mensmann <joerg_ml at bitplanet dot de>]

Hi,

I've now completed some additional tests, and it seems that the return
value of EnumDisplayMonitors() really depends on the return value of its
callback on my system. Here is the minimal test case:

static wBOOL CALLBACK
getMonitorInfoTestTRUE(HMONITOR hMonitor, HDC hdc, LPRECT rect, LPARAM _data)
{
    return TRUE;
}

static wBOOL CALLBACK
getMonitorInfoTestFALSE(HMONITOR hMonitor, HDC hdc, LPRECT rect, LPARAM _data)
{
    return FALSE;
}

Inserted into QueryMonitor():
  wBOOL result;
  result = EnumDisplayMonitors(NULL, NULL, getMonitorInfoTestTRUE, (LPARAM) data);
  ErrorF("getMonitorInfoTestTRUE returns: %d\n", (int)result);

  result = EnumDisplayMonitors(NULL, NULL, getMonitorInfoTestFALSE, (LPARAM) data);
  ErrorF("getMonitorInfoTestFALSE returns: %d\n", (int)result);

When running "Xwin.exe :0 -screen 0 @1" this prints:
  getMonitorInfoTestTRUE returns: 1
  getMonitorInfoTestFALSE returns: 0

I get the same results even when only one monitor is connected.

If you can't reproduce this on your machine, then maybe it is related to
the graphics driver. My configuration is NVIDIA 285.62 on Windows 7
(64-bit).

ciao
  Jörg
