Hi,
I have created a composite and set the layout to FillLayout. This
composite contains three Groups vertically and each groups contains a
variety of user input fields. However, as inputs are added to each
group the group does not expand as new inputs are added. I tried adding
V_SCROLL and H_SCROLL to the composite and although the scroll bars
appear - they have no effect. So what I have is useless scrollbars and
inputs that are rendered outside each groups viewable area so you cant
see them - help!
Thanks

ok that does not seem to have any effect. Here is what i have (keep in
mind that i am new at this).
protected void createTab (TabFolder folder){
TabItem item = null;
ScrolledComposite parent = null;
Group groupAttributes = null;
Group groupCustomerInfo = null;
Group groupDeliveryGeo = null;
Group groupEngagementManagement = null;
Group groupServicePlanning = null;
item = new TabItem(folder, SWT.BORDER);
item.setText("Details");
parent = new ScrolledComposite (folder, SWT.BORDER | SWT.V_SCROLL);
parent.setLayout(new FillLayout(SWT.VERTICAL));
groupAttributes = new Group (parent, SWT.SHADOW_ETCHED_IN);
groupAttributes.setText("Engagement Attributes");
groupCustomerInfo = new Group (parent, SWT.SHADOW_ETCHED_IN);
groupCustomerInfo.setText("Customer Information");
groupDeliveryGeo = new Group (parent, SWT.SHADOW_ETCHED_IN);
groupDeliveryGeo.setText("Delivery Geographics");
groupEngagementManagement = new Group (parent, SWT.SHADOW_ETCHED_IN);
groupEngagementManagement.setText("Delivery Geographics");
groupServicePlanning = new Group (parent, SWT.SHADOW_ETCHED_IN);
groupServicePlanning.setText("Delivery Geographics");
buildAttributes(groupAttributes);
buildCustomerInfo(groupCustomerInfo);
buildGeo(groupDeliveryGeo);
buildEngagementManagement(groupDeliveryGeo);
buildServicePlanning(groupDeliveryGeo);
folder.layout();
parent.layout();
item.setControl(parent);
}
here is a sample of a build method...
protected void buildServicePlanning(Composite parent) {
parent.setLayout(new GridLayout(4, true));
Label label = null;
GridData gridData = null;
label = new Label(parent, SWT.None);
label.setText("Service Planning:");
gridData = new GridData();
gridData.horizontalAlignment = SWT.RIGHT;
label.setLayoutData(gridData);
}
Any ideas?

Hi Brian,
It looks like the problem that you're having with the scrolled composite
is that you're using the SC as a parent for your group items. Try
instead using a regular composite as a child of the scrolled composite
and then setting the contents of the scrolled composite to be the
underlying composite. There is a really good snippet of how to use
scrolled composites on the api at
http://download.eclipse.org/eclipse/downloads/documentation/ 2.0/html/plugins/org.eclipse.platform.doc.isv/reference/api/ org/eclipse/swt/custom/ScrolledComposite.html
Yesh, thats a long URL
Hope that helps,
Ben

That worked great - thanks!
another change I had to make was item.setControl(scrolledParent);
I had it sent to the old parent and that was giving errors.
