Hi,
I just started using VEP to test the visual design features, and I guess
to be too hard to work with. I tried to reproduce the "Complex
GridLayout Example" of this link
" http://www.eclipse.org/articles/Article-Understanding%20Layo uts/Understanding%20Layouts.htm"
First of all, I tried to create a simple Shell with GridLayout. Well, I
define it to have 3 columns, and using the context menu I can show the
Grid (that on my opinion should be turned on by default). I put the a
Label on the first region and a Text on the second region, defining to
have horizontalSpan equals 2 and horizontalAlignment equals FILL. Til
now, not a big problem, but how do I put the widgets, below of this row?
It´s a hard and annoying task, because the widgets doesn´t respect the
region that it is placed. I must then put it the new widget on the right
side of the last column (on the margin), so it creates another "row". It
took some time to discover, but now it´s fine. But, if the last region
is from a widget that is spanning rows, then, when I put another widget
to "create another row", it doesn´t work as expected. It put this widget
on the first "row" of the spanning colection (on the first column also),
then I must select it and make some movements to put it on the newly
created row.
Another problem, that I guess must be added to bugzilla is when I save
the class, close it and open it again. It loses the visual apearance of
the "Text" widget. When I add a Text widget, the text is drawn like
"bold", but when I save, close and reopen, it is not bold anymore. Also,
other widgets has the same problem of being drawed diferently when after
saving, closing and reopening.
Anyone has some idea how to be more productive with VEP and SWT? Or
these problems are already known, and the VEP team is working on to
solve and improve the VEP?
Thanks in advance,
Alessandro

Hi Alessandro,
I agree that the behavior of the GridLayout editor can be a little odd
and take some time to get used to... but the problems you describe are
due to the way GridLayout works. The editor attempts to provide you
with the most accurate representation of the limitations of GridLayout
and how it will work in actual run time. You can't place controls in
fixed locations like you can in Swing's GridBagLayout... all you can do
is set the number of columns, and all the controls will flow into
position based on their requirements for horizontal and vertical span.
Did you use the Customize Layout dialog to help you set up the
GridLayout properties and the controls' GridData?
Sorry if this post sounds a bit defensive, I'm a bit biased on this
function because I wrote it ;) If you have any suggestions on how the
GridLayout editor can be improved, we can see if it's possible.
We've noticed that weird bolding bug with SWT. I just opened a bug
report for that issue: https://bugs.eclipse.org/bugs/show_bug.cgi?id=69373
Thanks for pointing out this problem and other issues with SWT. We
haven't really tested SWT too thoroughly yet, so posts like this from
early adopters and bugzilla reports are very useful for us.

Hi Jeff,
First of all, thanks for your answer.
Yes, I did use the Customize Layout dialog, and it really helps, since it's
easy to use.
I came from Delphi, and my first applications with Java has been Web
applications, so, my knowledge of Java Desktop is limited. I just start
using Eclipse at 2 weeks ago, and then a friend told me about SWT. Before I
had used Swing just a little, but for very simple examples.
This weekend I decided to dig a bit more on SWT and Layouts, and found that
tutorial. To me (Delphi developer) layouts appears to be unnecessary, since
while developing on Delphi, I can put components on the window, and use the
"Anchor" concept, to resize the objects when the window is resized. But
since I'm migrating to Java, I need to incorporate some concepts, and Layout
is one of them. So, following the tutorial I decided to create the
"GridLayout" example that appeared to be more interesting.
I read some tutorials about "FormLayout" and it appears to be the most used
(even being new on SWT, but already existent on Swing). So, maybe the
FormLayout should be easier to use. I will try it today.
Well, I will be very happy on contribute to the VE becomes easier to use,
and you can bet that I will post questions on this newsgroup with a
considerable frequence, since I'm very interesting on SWT and it's features.
Thanks in advance, and congratulations for the project.
