Hello,
I just started experimenting with Visual Editor. I created
a simple application using SWT. This application looks correct
when editing it with the visual editor, however, when I run it,
It does not look right, there is a multiple-line text field, it is
the only widget to show when the application is first run. After
resizing the app, all widgets display correctly. Any ideas on how
to fix this?
The code in question follows, it was generated by Visual
Editor 100% (no hand coding). I am writing and testing
using Linux/GTK. I haven't had a chance to test this under
any other platforms.

I can't remember the exact steps, but it was somewhat like this:
I clicked on the class icon in the toolbar (green circle with a "C+"
inside), clicked on "Visual Class", filled in the source folder,
package and class name, left the default SWT application style and
clicked on "finish".
If I remember correctly, I then changed the layout to GridLayout (BTW,
I might have set the size of the text component myself, through the
properties view, I was experimenting with the different options).
I then set the number of columns for the layout to be two, and
started adding components from the palette. A label, a text field,
another label, a multi-line text field, another label, a composite,
changed the layout for the composite to be GridLayout, set the number of
columns for the composite's layout to be 3, then added some radio buttons
to that composite, another label, another composite, again set the layout
for the new composite to be GridLayout, and set the number of columns to
be 4, added the check buttons to the second composite.
I don't think I did anything out of the ordinary.
In any case, I've been trying the Visual Editor in my spare time,
I'm not working on any super important documents or anything. In my day
job, I'm stuck with an HTML user interface for a J2EE application.

I'm thinking that we are missing a layout do to the size was changed
before we set griddata on anything.

What build of VE do you have?
Do Help->About Eclipse->Feature Details button. Select org.eclipse.ve,
then at the bottom of the dialog it will say "build id: ..." What build
id is listed?
The reason I ask is in the past we had problems with placing the
setSize, but we just tested it and seems to work correctly.
Also, there was a
text1.setSize(200, 200);
in createSShell which shouldn't of been there. When you switched to Grid
layout, we should of removed it.

Rich,
Here is the Visual Editor information displayed in the
feature details dialog:

Rich,
Moving sShell.setSize(new org.eclipse.swt.graphics.Point(600,400));
to be the very last line in createSShell() took care of the problem.
I'm not sure why the problem is there in the first place but this is
a fairly easy workaround.

I saw the bug reports, and I have a question, the bug reports say that
setText() and setSize() must be reversed. According to the workaround,
setSize() must be last in the createSShell() method. Looking at my
code, some components are added right after setText(), it looks like if
setText() and setSize() are reversed, then those components would be
added right after setSize().
This might not fix the problem since the components would still be
added after setSize(). I think Visual Editor
needs to add the setSize() as the last line in createSShell() regardless
of when the user sets the size of the shell.
Let me know if my assumption is correct.

The "workaround" is to place the setSize() at the end of the createMethod() (last statement).
Top down, VE will keep the setSize() at the end of the method even if you drop new components.
The question become a bit more tricky with this defect; what to do when the code's statement order is wrong.
Assume the following bad order (A should come before C):
C
A
Where do you inser B? before C or after A....

That bug had only to do with our template for creating the class. We
needed to change it so it created the class correctly. The code was
already correct when up in the ve for handling setSize() if setSize()
was last. The other bug listed was for handling when setSize() was not
in the correct place.

Hey guys,
I seem to remember that Win32 sends a bogus resize event on Shell.show().
That event causes the layout and explains the different behavior on
non-windows platforms.

Thanks Randy. In your opinion, should we file a PR against Platform/SWT
with the suggestion that SWT do the same thing across platforms here or
does this fall into SWT's "don't count on event ordering" mantra?
Thanks,
