Hi David,

Now I'm really really used CompositeTable in production application.

1st of all, I would like to say thanks for few things :-
1)what a nice pice of control!!
2)AbsoluteLayout, it works!! :-D
Now I able to design row's components using VE! Thanks!
3)Scrolling performance in AbsoluteLayout excellent!! no complaint!! super
fast!

Few questions/comments :-)

1)Nice if row height can be set or base on row's component height.
2)Is there anyway that I can insert row ?
3)Performance in "grid" not so good as AbsoluteLayout... slow scrolling...
4)Is tehre anyway that I can create a heighlight on row in grid ?
5)Readonly mode in grid ?

Thanks and hope to hear from you soon.
Hey, can I email you directly ? We can adopting CompositeTable as our
standard table control for our financial app.

Thanks

I know. Well, it's based on the *prototype row* component's height, and
all rows *must* be the same height. This can be a minor headache
sometimes. It really should compute the height of each row and use that
dynamically.

> 2)Is there anyway that I can insert row ?

From the user interface: Ctrl-Insert, by default.

From code: insert the row in your underlying collection,
setNumRows(numRows+1), compositeTable.refresh() or something like that.

If you're using data binding, the grid will refresh automatically if its
bound to a collection and a row is inserted or deleted in the collection.

Can you write a snippet and post it here please? CompositeTable is
designed for (1) speed, and (2) in-place editing. Any performance
problems should be reported as bugs.

Yes, but it's slightly tricky. Basically, you have to write an SWT
control that behaves like the highlight bar in a list box. Off the top
of my head (I'm away from my code that does this right now), this means:

1) Process traverse events to tell SWT to accept focus.
2) In focusIn:

setBackground(Display.getCurrent().getSystemColor(SWT.COLOR_ LIST_BOX_SELECTION));

(That's not the right SWT constant, but you'll find it; sorry I don't
have the actual code handy to look it up for you.)

3) in focusOut:

setBackground(Display.getCurrent().getSystemColor(SWT.COLOR_ WIDGET_BACKGROUND));

(I'm pretty sure of that color constant but check it)

Then use SWT Label objects for your actual data.

> 5)Readonly mode in grid ?

Use SWT Label objects to display your data and it'll be read-only. :-)

> Thanks and hope to hear from you soon. Hey, can I email you directly ?

If you need consulting, training, or mentoring services, by all means
email me directly. :-)

However, I prefer for technical questions to go to this newsgroup
because then others will benefit from the answers, and as long as you
use [CompositeTable] in the subject, your message will automatically be
forwarded to my email anyway. :-)

Excellent. As always, patches are appreciated. :-)

Best regards,

Hi Ivan,

No footer (yet), but maybe soon. :-)

Thanks for the bug report. Let's continue this discussion there. :-)
