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.
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.
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.
29 - unarchive MicroWindows 0.89pre7
30 - change 'config' to use X11 and any other options you feel fit,
31 such as verbose compilation
32 - cd to src/mwin and apply microwindows.patches (from wxWindows:
33 docs/microwin/microwindows.patches) to fix PeekMessage
34 - compile by typing 'make' from within the MicroWindows src directory
38 - untar the wxMicroWindows port/download from CVS
39 - and change the TOP variable at the top of src/msw/makefile.mic
40 to reflect where MicroWindows is installed
41 - type 'make all' from src/msw. To clean, use cleanwx and NOT clean
42 since that will clean MicroWindows itself
43 - to make the sample, cd into samples/minimal, edit the TOP variable,
46 Running 'minimal' runs the virtual MicroWindows desktop
47 and the minimal sample, since in a MicroWindows WIN32 application
48 they are one and the same binary.
53 A frame comes up :-) The menus don't work properly just yet.
58 wxMicroWindows is essentially the wxMSW port + wxUniversal
59 widgets. Lots of things in include/wx/univ/setup.h are switched
60 off to allow the port to compile. There are also #ifdefs
61 switching off further functionality, such as most wxBitmap
62 functions, pending proper implementation.
64 There are some WIN32 API functions not implemented by MicroWindows
65 that are instead stubbed out in include/wx/msw/microwin.c,
66 and 'implemented' in src/msw/microwin.c. Some of these functions
67 are important, some less so. They will need to be implemented
68 in due course. But implementing missing functionality in this way
69 is preferably to proliferating many #ifdefs in the
70 wxMSW/wxMicroWindows port itself.
72 Things missing from MicroWindows that need to be worked around
73 ==============================================================
75 No ::GetKeyState (see include/wx/msw/private.h). Should probably use
76 GdOpenKeyboard/GdCloseKeyboard/GdReadKeyboard. Could perhaps emulate
79 No ::CreateBitmap or BITMAPINFO. But BMPs can be converted
80 to C using convbmp, then need to use Gr... functions.
81 We MUST implement creation from XPMs, since wxUniversal
82 makes use of XPMs, or else create our own bitmaps for
83 drawing radioboxes, checkboxes etc.: see renderers
86 No ::DestroyIcon, ::DestroyCursor - use ::DestroyObject instead?
87 Also no LoadCursor, LoadImage. So how do we make cursors? No ::SetCursor.
89 wxDC: no ::GetTextColor, ::GetBkColor, ::IntersectClipRect,
92 No ::SetMenu, so no menus or menubars (now implemented by
95 No ::GetObject so we can't get LOGFONT from an HFONT
96 in wxSystemSettings (worked around by passing HFONT to
97 the wxFont constructor).
99 No ::CreateDialog so how do we create dialogs? Simulate
