   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 - untar the wxMicroWindows port/download from CVS
  49
  50 - change the TOP variable at the top of src/msw/makefile.mic
  51   to reflect where MicroWindows is installed
  52
  53 - type 'make all' from src/msw. To clean, use cleanwx and NOT clean
  54   since that will clean MicroWindows itself
  55
  56 - to make the sample, cd into samples/minimal, edit the TOP variable,
  57   and type 'make all'
  58
  59 Running 'minimal' runs the virtual MicroWindows desktop
  60 and the minimal sample, since in a MicroWindows WIN32 application
  61 they are one and the same binary.
  62
  63 Status
  64 ======
  65
  66 The minimal sample is almost fully-functional, apart from minor
  67 menu presentation issues (no borders, for example).
  68
  69 Implementation Notes
  70 ====================
  71
  72 wxMicroWindows is essentially the wxMSW port + wxUniversal
  73 widgets. Lots of things in include/wx/univ/setup.h are switched
  74 off to allow the port to compile. There are also #ifdefs
  75 switching off further functionality, such as most wxBitmap
  76 functions, pending proper implementation.
  77
  78 There are some WIN32 API functions not implemented by MicroWindows
  79 that are instead stubbed out in include/wx/msw/microwin.c,
  80 and 'implemented' in src/msw/microwin.c. Some of these functions
  81 are important, some less so. They will need to be implemented
  82 in due course. But implementing missing functionality in this way
  83 is preferably to proliferating many #ifdefs in the
  84 wxMSW/wxMicroWindows port itself.
  85
  86 Things missing from MicroWindows that need to be worked around
  87 ==============================================================
  88
  89 No ::GetKeyState (see include/wx/msw/private.h). Should probably use
  90 GdOpenKeyboard/GdCloseKeyboard/GdReadKeyboard. Could perhaps emulate
  91 GetKeyState this way.
  92
  93 No ::CreateBitmap or BITMAPINFO. But BMPs can be converted
  94 to C using convbmp, then need to use Gr... functions.
  95 We MUST implement creation from XPMs, since wxUniversal
  96 makes use of XPMs, or else create our own bitmaps for
  97 drawing radioboxes, checkboxes etc.: see renderers
  98 in src/univ.
  99
 100 No ::DestroyIcon, ::DestroyCursor - use ::DestroyObject instead?
 101 Also no LoadCursor, LoadImage. So how do we make cursors? No ::SetCursor.
 102
 103 wxDC: no ::GetTextColor, ::GetBkColor, ::IntersectClipRect,
 104 ::GetClipBox
 105
 106 No ::SetMenu, so no menus or menubars (now implemented by
 107 wxUniversal).
 108
 109 No ::GetObject so we can't get LOGFONT from an HFONT
 110 in wxSystemSettings (worked around by passing HFONT to
 111 the wxFont constructor).
