so it'll work with both modern computers and 1992-ones? Full source is
included, overloaded with comments. IBM C Set/2 makefile present. Just
a longer period of DosSleep() and a recompile may be needed here? The
executing speed seems to be the only problem.

FWIW: modifying is allowed, and it may be useless nowadays to honour a
mentioned request to distribute both the outdated original version and
the fixed version.

approach. Since the main stepping stone for people to help me is the
need of VAC++ 4.0 I decided to continue the work on the Watcom branch
created sometime ago.

After some work, I was finally able to compile the whole SWT port
under Watcom + ant 1.5.4 + Java 1.3.1 . After that I began testing the
testcases. The first one works, meaning the JNI interface works. The
second test doesn't. The test creates a main frame and a client
window, but it only draws the window's borders and then it enters in a
loop where there is a WM_PAINT message being sent. The machine becomes
on the verge of freezing and it takes some luck to get it back. The
same test, using the DLL created with VAC++ 4.0 works just fine. The
Java sources are the same and so it's the C code.

The problem starts with a call to WinShowWindow. I'm pretty lost,
since I don't know where to start to look for answers. Maybe a
compilers option?, simply I can't imagine why I get a different
behavior from the same code on different compilers.

Here is the compilers options being used:

!include

objects=editcol.obj structs.obj swt.obj callback.obj
CFLAGS=-w4 -e25 -zq -od -d2 -bd -6r -bt=os2 -mf

$(SWT_LIB) : $(objects)
wlink name $@ SYS os2v2 dll initi termi op m, maxe=25, q, symf, many
file { $(objects) }
wlib -q -n -b $*.lib +$*.dll
copy $(SWT_LIB) $(SWT_LOCATION)

all : $(SWT_LIB)

clean:
-del *.obj *.err *.dll *.lib *.map $(SWT_LOCATION)\$(SWT_LIB)

editcol.obj : editcol.c .AUTODEPEND
wcc386 editcol $(CFLAGS)

structs.obj : structs.c .AUTODEPEND
wcc386 structs $(CFLAGS)

swt.obj : swt.c .AUTODEPEND
wcc386 swt $(CFLAGS)

callback.obj : "..\..\..\Eclipse SWT\common\library
\callback.c" .AUTODEPEND
wcc386 "..\..\..\Eclipse SWT\common\library\callback.c" $(CFLAGS)

Thanks

CM_INSERTRECORDARRAY message. If WinSendMsg() returns 0, it indicates the
request failed for some reason and WinGetLastError() has the reason.
WinGetLastError() uses an anchor block to decide where the error code
exists.
My problem is how to *get* the appropriate anchor block. As it turns out
it is not the anchor block of the window where the request failed but the
thread that initiated the request. A window's anchor block is retrieved
with WinQueryAnchorBlock(HWND) but that is no use in the multi-threaded
application.
How do I get the current thread's anchor block?

is it possible that the title of the selected notebook page is different
from the text in the selected tab?

E.g.:

__________ _________
/Category 1\ /Category2\
_____________/ \__________________________________

intended.

The child window which has the focus seems to affect the save/restore
process. For example, if window X has the focus the restore places the
windows one way but, with the same arrangement of windows, if window Y
has the focus the restore places the windows differently.

Please help me with references to documentation and/or sample code
which would show how to accomplish this task?

TIA.

int class = SOME API;
if(class == WC_MENU)
paint the menu item
else if(class == WC_LISTBOX)
paint the list box

Is there something like that.

Thanks

The left one is a tree
view; the right one is in details views. Selecting a folder in the tree
(left) view causes the contents of the folder to display in the details
view container.
Also the tree view allows multiple levels which may be expanded and
collapsed.
When an expanded view is collapsed, the usual (expected) sequence of
events is CN_EMPHASIS and the flags indicate a loss of emphasis. Then
another CN_EMPHASIS with the flags showing a gain of emphasis. This is good.
Based on the above, the code expects to clear the details window before
re-populating it.
But the opposite sequence is also happens! The gain of emphasis can
arrive *before* the loss. This results with the details window briefly
showing the contents of both folders before it is cleared, showing nothing.

Is this normal behavior?

all file objects (WPDataFile or derived) have a "Become" page (or
"Object class" ?) where you can change their class to a selection of
other compatible classes where "compatible classes" do not necessarily
have to be anchestors of the current class (they can also be children of
anchestors, therefore can be siblings of parent or grandparent etc.
classes) but I guess they are restricted to be at least of WPFileSystem
or derived classses.
The user interface is there but I cannot see what SOM method supports
that. Anyone have any insight what SOM method supports this class change
or any idea how I can debug what SOM method is called on that user action ?
I have found method somCastObjCls (defined for SOMClass class) which
maybe does the right thing. However it is not documented and therefore
the parameters not defined (also not in the interface repository) so it
will be trial and error to find the right parameters ...

Maybe the interface is: BOOL somCastObjCls(SOMClass *receiver,SOMObject
*targetObj,somId *targetClass);

Any help or hints ?

you can feel the power of new version today if install a release-
candidate.

Which features to implement in eComStation 2.1? The users post their
requests to the forums:
