   1 wxMicroWindows port
   2 ===================

   6 This is a port of wxWindows to MicroWindows, under Linux.
   7 Widgets are supplied by the wxUniversal project, while the
   8 underlying port uses the Windows ports with small modifications
   9 for the MicroWindows API.
  10
  11 There are many things missing from MicroWindows that will
  12 make the port quite limited for the time being. I haven't
  13 worked out how to create bitmaps, though there is a BMP to C
  14 converter. There are no common dialogs (we will use generic ones),
  15 and only one WIN32 app may be run at a time.
  16
  17 Note that you can gain confidence in the WIN32/wxUniversal
  18 combination by compiling wxUniversal under Windows using VC++,
  19 using src/wxvc_universal.dsp. You can compile the minimal
  20 and widgets samples in wxUniversal mode using the
  21 UnivDebug and UnivRelease targets. Most of the code is shared
  22 between this combination, and the wxMicroWindows port.

  24 Installation
  25 ============
  26
  27 MicroWindows:
  28
  29 - unarchive MicroWindows 0.89pre7
  30
  31 - change 'config' to use X11 and any other options you feel fit.
  32   Suggestions for changes to the defaults:
  33
  34   ERASEMOVE=N (otherwise moving windows will look messy)
  35   X11=Y
  36   OPTIMIZE=N
  37   DEBUG=Y
  38   VERBOSE=Y
  39
  40 - apply microwindows.patches (from wxWindows:
  41   docs/microwin/microwindows.patches) to fix PeekMessage
  42   and other issues
  43
  44 - compile by typing 'make' from within the MicroWindows src directory
  45
  46 wxMicroWindows:
  47
  48 - Download wxMSW 2.3.3 or greater, or get it from CVS
  49
  50 - Copy include/wx/msw/setup_microwin.h to include/wx/setup.h if
  51   include/wx/setup.h doesn't exist
  52
  53 - change the TOP variable at the top of src/msw/makefile.mic
  54   to reflect where MicroWindows is installed
  55
  56 - type 'make all' from src/msw. To clean, use cleanwx and NOT clean
  57   since that will clean MicroWindows itself
  58
  59 - to make the sample, cd into samples/minimal, edit the TOP variable,
  60   and type 'make all'
  61
  62 Running 'minimal' runs the virtual MicroWindows desktop
  63 and the minimal sample, since in a MicroWindows WIN32 application
  64 they are one and the same binary.
  65
  66 Status
  67 ======
  68
  69 The minimal sample is almost fully-functional, apart from minor
  70 menu presentation issues (no borders, for example).
  71
  72 Implementation Notes
  73 ====================
  74
  75 wxMicroWindows is essentially the wxMSW port + wxUniversal
  76 widgets. Lots of things in include/wx/univ/setup.h are switched
  77 off to allow the port to compile. There are also #ifdefs
  78 switching off further functionality, such as most wxBitmap
  79 functions, pending proper implementation.
  80
  81 There are some WIN32 API functions not implemented by MicroWindows
  82 that are instead stubbed out in include/wx/msw/microwin.c,
  83 and 'implemented' in src/msw/microwin.c. Some of these functions
  84 are important, some less so. They will need to be implemented
  85 in due course. But implementing missing functionality in this way
  86 is preferably to proliferating many #ifdefs in the
  87 wxMSW/wxMicroWindows port itself.
  88
  89 Things missing from MicroWindows that need to be worked around
  90 ==============================================================
  91
  92 No ::GetKeyState (see include/wx/msw/private.h). Should probably use
  93 GdOpenKeyboard/GdCloseKeyboard/GdReadKeyboard. Could perhaps emulate
  94 GetKeyState this way.
  95
  96 No ::CreateBitmap or BITMAPINFO. But BMPs can be converted
  97 to C using convbmp, then need to use Gr... functions.
  98 We MUST implement creation from XPMs, since wxUniversal
  99 makes use of XPMs, or else create our own bitmaps for
 100 drawing radioboxes, checkboxes etc.: see renderers
 101 in src/univ.
 102
 103 No ::DestroyIcon, ::DestroyCursor - use ::DestroyObject instead?
 104 Also no LoadCursor, LoadImage. So how do we make cursors? No ::SetCursor.
 105
 106 wxDC: no ::GetTextColor, ::GetBkColor, ::IntersectClipRect,
 107 ::GetClipBox
 108
 109 No ::SetMenu, so no menus or menubars (now implemented by
 110 wxUniversal).
 111
 112 No ::GetObject so we can't get LOGFONT from an HFONT
 113 in wxSystemSettings (worked around by passing HFONT to
 114 the wxFont constructor).
