+wxMicroWindows port
+===================
+
+Julian Smart 2001-07-02
+
+This is a snapshot of my experimental port of wxWindows to
+MicroWindows. Widgets are supplied by the wxUniversal project,
+while the underlying port uses the Windows ports with small
+modifications for the MicroWindows API.
+
+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
+converter. There are no menus, no common dialogs, 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.
+
+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).
+
+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.
+
+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 :-)
+
+Notes
+=====
+
+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.
+
+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
+in wxSystemSettings.
+
+No ::CreateDialog so how do we create dialogs? Simulate
+one with a frame I guess.
