wxMicroWindows port
|
|
===================
|
|
|
|
Julian Smart 2001-07-02
|
|
|
|
This is a port of wxWindows to MicroWindows, under Linux.
|
|
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 common dialogs (we will use generic ones),
|
|
and only one WIN32 app may be run at a time.
|
|
|
|
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
|
|
============
|
|
|
|
MicroWindows:
|
|
|
|
- unarchive MicroWindows 0.89pre7
|
|
- change 'config' to use X11 and any other options you feel fit,
|
|
such as verbose compilation
|
|
- cd to src/mwin and apply microwindows.patches (from wxWindows:
|
|
docs/microwin/microwindows.patches) to fix PeekMessage
|
|
- compile by typing 'make' from within the MicroWindows src directory
|
|
|
|
wxMicroWindows:
|
|
|
|
- untar the wxMicroWindows port/download from CVS
|
|
- and 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'
|
|
|
|
Running 'minimal' runs the virtual MicroWindows desktop
|
|
and the minimal sample, since in a MicroWindows WIN32 application
|
|
they are one and the same binary.

A frame comes up :-) The menus don't work properly just yet.

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.
|
|
|
|
Things missing from MicroWindows that need to be worked around
|
|
==============================================================
|
|
|
|
No ::GetKeyState (see include/wx/msw/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 (now implemented by
|
|
wxUniversal).
|
|
|
|
No ::GetObject so we can't get LOGFONT from an HFONT
|
|
in wxSystemSettings (worked around by passing HFONT to
|
|
the wxFont constructor).
|
|
|
|
No ::CreateDialog so how do we create dialogs? Simulate
|
|
one with a frame...
