Hi all,
Like almost everybody, I want to use the same code in RAP and RCP.
I'm working on a editor with Forms, Section and Table using GridLayout and
I do not have the same display in RCP and RAP (RCP result is the one I
also want on RAP).
Am I missing something ?
Thanks,
Loïc
Here is the code :
public class LayoutEditor extends EditorPart
{
private ManagedForm managedForm;
@Override
public void createPartControl(Composite parent)
{
FormToolkit toolkit = new FormToolkit(parent.getDisplay());
managedForm = new ManagedForm(toolkit, toolkit
.createScrolledForm(parent));
managedForm.getForm().setText("Title");
GridLayout layout = new GridLayout();
layout.marginWidth = 2;
managedForm.getForm().getBody().setLayout(layout);
Section paramSection = toolkit.createSection(managedForm.getForm()
.getBody(), Section.TITLE_BAR | Section.TWISTIE
| Section.CLIENT_INDENT);
paramSection.setLayoutData(new GridData(SWT.FILL, SWT.FILL, false,
false));
paramSection.setText("param section");
paramSection.addExpansionListener(new ExpansionAdapter()
{
@Override
public void expansionStateChanged(ExpansionEvent e)
{
managedForm.getForm().reflow(true);
}
});
Composite paramSectionClient =
toolkit.createComposite(paramSection,
SWT.NONE);
paramSection.setClient(paramSectionClient);
paramSectionClient.setLayout(new GridLayout());
Section resultSection = toolkit.createSection(managedForm.getForm()
.getBody(), Section.TITLE_BAR | Section.TWISTIE
| Section.CLIENT_INDENT);
resultSection.setLayoutData(new GridData(SWT.FILL, SWT.FILL, false,
false));
resultSection.setText("result section");
resultSection.addExpansionListener(new ExpansionAdapter()

I guess it is unlikely that anyone reading here has the time to analyze
your code to find out what exactly the problem is you experience. You
should rather try to describe the difference and/or provide screenshots.
In general, there is no difference between layouts in RAP and in RCP -
in fact, it's the exact same code. What might cause a different
appearance is that certain widgets may have slightly different preferred
sizes, due to different font sizes etc. Anyway, you should try to narrow
down the problem.
Best regards,
Ralf

Thanks Ralf for your answer.
First, how can I add screenshot via the Eclipse NewsPortal ?
Then I will try to describe the differences :
I have a ScrolledForm with a Section. Everybody have GridLayout / GridData
with SWT.FILL and Grab excess to false.
In the Section I have a Table with several rows and columns.
In RCP the table is well displayed with scrollbar on the editor to see all
of it.
In RAP the table is really small, the same width as the section title (so
only one column can be see) and the height to see one row. I have
scrollbar on the table to see other columns / rows.
It may be more explicit with screenshot (if someone can help me to provide
them...)
Thanks,
Loïc

Hi,
have you tried to replace
new GridData(SWT.FILL, SWT.FILL, false, false));
with
new GridData(SWT.FILL, SWT.FILL, true, true));
when creating the table and its parent composites?
However, if exactly the same code layouts different in RCP and RAP, this
is probably a bug.
Regards,
Stefan.

Thanks you for looking at my screenshots.
Yes, it's exactly the same code. Is it possible to consider this bug ?
I've tried with grabExcess to true like you say and in RAP the table take
indeed all the editor available space. However, if there is not enough
space, the horizontal scrollbar is created on the table (instead of on the
editor in RCP).
Moreover in RCP, when I increase the editor horizontally, the table also
increase its last column width to fill all the space (and I want my table
to always keep its minimum size).
Regards,
Loïc

The problem is that the Table#computeSize() method obviously returns the
default 64x64 px (plus some px for the border). With this shortcoming,
it's not possible to get the "minimum" size for the Table. You'll have
to find a workaround, like Stefan suggested. Sorry for that.
I reopened bug 223895: [Table] Revise Table#computeSize()
https://bugs.eclipse.org/bugs/show_bug.cgi?id=223895

just a little comment, you should consider checking http://www.eclipse.org/rap/noteworthy/ regularly. there you can see what the milestones bring with them and the fixed bugs, then you'll see why it
is most recommendable to use the latest milestone release :).

Yes, I'm sorry, I should have tried with the lastest milestone.
However I won't use it because my application may be released soon and I
need a stable version. I hope it won't be so soon so I could integrated
1.2.0 final version in June.
