Hi everybody,
today I encountered a rendering difference between RAP and RCP
GridLayouting (using RAP 1.2 M5).
I am building a view that displays data only through labels. These
labels are layouted by a GridLayout. The first column contains a defined
caption, the second column will contain labels with the actual data but
the labels are empty on startup.
The screenshot rcp_gridLayout.png shows the view in RCP. The content
labels are colored blue. (The last row "Responsible" has a composite in
the second column that is layouted by a gridLayout itself).
When the view is opened in RAP, the labels are shortened to a minimun.
This is shown in rap_gridLayout.png.
I don't know where to locate this bug, maybe it is the Label that gives
a wrong size or something. I would appreciate any help to make the
labels look like the ones in RCP.
Regards,
Bj

Hi Björn,
can you provide a small code snippet that shows how your form is created?

Sure, here is the createPartControl of the view:
----------------------------------------------------
@Override
public void createPartControl(Composite parent) {
Display display = parent.getDisplay();
// register as SelectionListener to the View OrderssSummary
getSite().getPage().addSelectionListener(this);
final Form orderDetailsForm = toolkit.createForm(parent);
final Composite body = orderDetailsForm.getBody();
final GridLayout gridLayout = new GridLayout();
body.setLayout(gridLayout);
final Composite composite = new Composite(body, SWT.NONE);
final GridLayout gridLayout_1 = new GridLayout();
gridLayout_1.numColumns = 2;
composite.setLayout(gridLayout_1);
final GridData gd_composite = new GridData(SWT.LEFT, SWT.TOP, true, false);
gd_composite.heightHint = 106;
composite.setLayoutData(gd_composite);
toolkit.adapt(composite);
final Label orderLabel = toolkit.createLabel(composite, "Order", SWT.NONE);
dataOrder = toolkit.createLabel(composite, "new Forms Label", SWT.NONE);
dataOrder.setBackground(ColorManager.getInstance(display).ge tColor( "#5050FF"));
dataOrder.setRedraw(true);
dataOrder.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, false, false));
final Label statusLabel = toolkit.createLabel(composite, "Status",
SWT.NONE);
dataStatus = toolkit.createLabel(composite, "new Forms Label", SWT.NONE);
dataStatus.setRedraw(true);
dataStatus.setBackground(ColorManager.getInstance(display).g etColor( "#5050FF"));
dataStatus.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, false, false));
final Label labelPriority = toolkit.createLabel(composite, "Priority",
SWT.NONE);
dataPriority = toolkit.createLabel(composite, "new Forms Label", SWT.NONE);
dataPriority.setRedraw(true);
dataPriority.setBackground(ColorManager.getInstance(display) .getColor( "#5050FF"));
final GridData gd_dataPriority = new GridData(SWT.FILL, SWT.CENTER,
false, false);
dataPriority.setLayoutData(gd_dataPriority);
final Label offerLabel = toolkit.createLabel(composite, "Offer", SWT.NONE);
dataOffer = toolkit.createLabel(composite, "new Forms Label", SWT.NONE);
dataOffer.setRedraw(true);
dataOffer.setBackground(ColorManager.getInstance(display).ge tColor( "#5050FF"));
dataOffer.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, false, false));
final Label labelResponsible = toolkit.createLabel(composite,
"Responsible", SWT.NONE);
final Composite composite_1 = new Composite(composite, SWT.NONE);
composite_1.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, false,
false));
final GridLayout gridLayout_2 = new GridLayout();
gridLayout_2.marginWidth = 0;
gridLayout_2.marginHeight = 0;
gridLayout_2.numColumns = 2;
composite_1.setLayout(gridLayout_2);
toolkit.adapt(composite_1);
dataResponsible1 = toolkit.createLabel(composite_1, "new Forms Label",
SWT.NONE);
dataResponsible1.setBackground(ColorManager.getInstance(disp lay).getColor( "#5050FF"));
dataResponsible1.setLayoutData(new GridData());
dataResponsible2 = toolkit.createLabel(composite_1, "new Forms Label",
SWT.NONE);
dataResponsible2.setBackground(ColorManager.getInstance(disp lay).getColor( "#5050FF"));
dataResponsible2.setLayoutData(new GridData());
final Composite composite_2 = new Composite(body, SWT.NONE);
composite_2.setLayoutData(new GridData(SWT.LEFT, SWT.CENTER, true, false));
composite_2.setLayout(new GridLayout());
toolkit.adapt(composite_2);
// toolkit.paintBordersFor(body);
orderDetailsForm.setText("Overview");
m_bindingContext = initDataBindings();
}
--------------------------------------------------

Björn

Björn,
for me it looks as if the problem is not the layout of the form itself
but the size of the enclosing Composite. You could simply add a
background color to the composite that contains all the labels to be
able to see its size. If it turns out to be too way too small, you
should be able to create a simplified snippet with only one single label
that shows the same effect. This way you could narrow down the problem.
Could you try this?
Thanks, Ralf

Hi Ralf,
I narrowed the problem down a little bit. While testing I had the
feeling that this difference is somehow connected to data binding.
Anway, I rebuilt the whole View using text filds rather than Labels so
that this is not an issue for me anymore. If you want to have a further
look at this it would be nice, but to me it is not critical anymore. I
attached the source after the message.
Thanks for your help!

Björn
P.S.: Here is the source that is rendered differently in RAP:

Hi Björn,
your snippet renders almost the same in RAP and RCP. I guess your
problem is that you do not force the main composite to have full size
(e.g. by setting a FillLayout on the parent) and you do not set
appropriate layout data on the inner composites, but I do not see any
difference between RAP and RCP here.
