i'm trying to put a simple gef/draw2d diagram (view only, no edit) into
a table cell. i'm guessing there's no way to do this using SWT/JFace
tables (short of creating an image from the diagram). is that right?
if so, what are other strategies that have been used. using an emulated
table like KTable? building a table using GEF/draw2d only (with some
kind of grid layout)?
thx for any suggestions.
regards,

the screenshots look nice. i'll take a look at the code as well.
what was your rationale for rolling your own (not re-using egs. KTable
or SWTDatePicker etc.)? i'm not criticizing your decision, just want to
know your thinking.

Al,
Thanks, hopefully in the next week or so I'll get time to put up an
actual website.
Well, the decision to role my own was not an easy one, mainly because
I want to be writing a contact manager and not widgets.
1. Linux GTK is our top priority, and I got fed up testing custom
widgets that only work on Windows (when you look at the code, notice all
the "if(gtk) or if(win32) clauses).
2. Some features / functionality just wasn't found - date / time masks
is one example, not using native components is another.
3. When I started I only needing a simple list of composites; I tried
the one at SWTPlus but got frustrated with its break from SWT
convention; KTable was overkill, and again, didn't follow SWT very well;
finally, seeing as how easier a simple list was to make I just went
ahead with it.
Then, of course, requirements changed... I had already written in SWT
Tables / TabelViewers and was starting to fight their limitations.
Again I looked at KTable but to my knowledge KTable does not support a
Tree, does not use a native header, and does not have a JFace style
viewer. I'm a big fan of JFace, and if you look at the implementation
code in org.aspencloud.widgets.test.CTableTests1.java you'll see that
using CTableTree / CTableTreeViewer is identical to using a SWT Tree
with Columns and TreeViewer
If I understand them correctly, the design goals of KTable, and others
I tried, are geared toward creating a Grid Control, which is not what I
need. I need a List with Columns, which looks as native as possible,
can have a Tree in any one of those columns, and is especially good at
handling expandable cells (not necessarily spanning). Thus, "it all
depends on what you want your table to do".
I think KTable and CTableTree have different enough goals to not
really be competing with each other. And if they are, then hopefully
we've both learned enough on our separate paths to be positive
influences when the Eclipse Foundation finally approves Nebula :)
sorry this has gotten a bit lengthy, and I feel I've taken up enough GEF
bandwidth for a non-GEF topic. I'd appreciate hearing your feedback
(and criticism) but maybe it should be moved to either the SWT newsgroup
or to SourceForge.
cheers!
