-This is a snapshot of my experimental port of wxWindows to
-MicroWindows. Widgets are supplied by the wxUniversal project,

There are many things missing from MicroWindows that will
make the port quite limited for the time being. I haven't
worked out how to create bitmaps, though there is a BMP to C

-one WIN32 app may be run at a time.
+converter. There are no common dialogs (we will use generic ones),
+and only one WIN32 app may be run at a time.
-Some things can no doubt be worked around, and/or MicroWindows
-itself tweaked. Lots of wxWin functionality is just switched off or
-commented out.
+Note that you can gain confidence in the WIN32/wxUniversal
+combination by compiling wxUniversal under Windows using VC++,
+using src/wxvc_universal.dsp. You can compile the minimal
+and widgets samples in wxUniversal mode using the
+UnivDebug and UnivRelease targets. Most of the code is shared
+between this combination, and the wxMicroWindows port.
Installation
============
-First install MicroWindows - untar it, change config to
-use X11 and any other options you feel fit, apply
-microwindows.patches to fix PeekMessage, and compile
-(type 'make' from within the src directory).
+MicroWindows:
-Untar the wxMicroWindows port, and change the TOP variable at the
-top of src/microwin/Makefile to reflect where MicroWindows is installed.
-Type 'make all' from src/microwin. To clean, use cleanwx and NOT clean
-since that will clean MicroWindows itself.
+- unarchive MicroWindows 0.89pre7
+
+- change 'config' to use X11 and any other options you feel fit.
+ Suggestions for changes to the defaults:
+
+ ERASEMOVE=N (otherwise moving windows will look messy)
+ X11=Y
+ OPTIMIZE=N
+ DEBUG=Y
+ VERBOSE=Y
+
+- apply microwindows.patches (from wxWindows:
+ docs/microwin/microwindows.patches) to fix PeekMessage
+ and other issues
+
+- compile by typing 'make' from within the MicroWindows src directory
+
+wxMicroWindows:
+
+- untar the wxMicroWindows port/download from CVS
+
+- change the TOP variable at the top of src/msw/makefile.mic
+ to reflect where MicroWindows is installed
+
+- type 'make all' from src/msw. To clean, use cleanwx and NOT clean
+ since that will clean MicroWindows itself
+
+- to make the sample, cd into samples/minimal, edit the TOP variable,
+ and type 'make all'
-To make the sample, cd into samples/minimal, edit the TOP variable,
-and type 'make all'.
Running 'minimal' runs the virtual MicroWindows desktop
and the minimal sample, since in a MicroWindows WIN32 application
they are one and the same binary.
Status
======
-A frame comes up :-)
+The minimal sample is almost fully-functional, apart from minor
+menu presentation issues (no borders, for example).
+
+Implementation Notes
+====================
+
+wxMicroWindows is essentially the wxMSW port + wxUniversal
+widgets. Lots of things in include/wx/univ/setup.h are switched
+off to allow the port to compile. There are also #ifdefs
+switching off further functionality, such as most wxBitmap
+functions, pending proper implementation.
+
+There are some WIN32 API functions not implemented by MicroWindows
+that are instead stubbed out in include/wx/msw/microwin.c,
+and 'implemented' in src/msw/microwin.c. Some of these functions
+are important, some less so. They will need to be implemented
+in due course. But implementing missing functionality in this way
+is preferably to proliferating many #ifdefs in the
+wxMSW/wxMicroWindows port itself.
-Notes
-=====
+Things missing from MicroWindows that need to be worked around
+==============================================================
-No ::GetKeyState (see microwin/private.h). Should probably use GdOpenKeyboard/GdCloseKeyboard/GdReadKeyboard. Could perhaps emulate GetKeyState this way.

No ::CreateBitmap or BITMAPINFO. But BMPs can be converted
to C using convbmp, then need to use Gr... functions.
+We MUST implement creation from XPMs, since wxUniversal
+makes use of XPMs, or else create our own bitmaps for
+drawing radioboxes, checkboxes etc.: see renderers
+in src/univ.
No ::DestroyIcon, ::DestroyCursor - use ::DestroyObject instead?
Also no LoadCursor, LoadImage. So how do we make cursors? No ::SetCursor.
wxDC: no ::GetTextColor, ::GetBkColor, ::IntersectClipRect,
::GetClipBox
-No ::SetMenu, so no menus or menubars.

No ::GetObject so we can't get LOGFONT from an HFONT

+the wxFont constructor).
-No ::CreateDialog so how do we create dialogs? Simulate
-one with a frame I guess.
