Philipe you have to set the minsize of the scrolledcomposite to a size that
you want the squeeze to stop.
e.g.
ScrolledComposite.setMinsize(-1, timelineModel.getTracks().size() * 10)
try this:
import java.util.concurrent.TimeUnit;
import org.eclipse.nebula.widgets.timeline.ILane;
import org.eclipse.nebula.widgets.timeline.ITimeline;
import org.eclipse.nebula.widgets.timeline.ITrack;

import org.eclipse.nebula.widgets.timeline.jface.TimelineViewer;
import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.ScrolledComposite;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;

import org.eclipse.swt.widgets.Shell;
public class TimeLineApp {
private static ITimeline fModel;

final Display display = new Display();
final Shell shell = new Shell(display);
shell.setText("Nebula Timeline");
shell.setLayout(new GridLayout(1, false));
final ScrolledComposite scrolledComposite = new ScrolledComposite(shell,
SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);
scrolledComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true,
true, 1, 1));
scrolledComposite.setExpandHorizontal(true);
scrolledComposite.setExpandVertical(true);
final Control control = createControl(scrolledComposite);
scrolledComposite.setContent(control);
final int height = fModel.getTracks().size() * 50;
scrolledComposite.setMinSize(-1, height);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
public static Control createControl(Composite parent) {
final TimelineViewer timelineViewer = new TimelineViewer(parent, SWT.NULL);
fModel = (ITimeline) timelineViewer.getInput();
new TimelineDataBinding(timelineViewer, fModel, 300);
createRandomContent(fModel);
timelineViewer.refresh();
return timelineViewer.getControl();
}
private static void createRandomContent(ITimeline model) {
final ITrack track1 = model.createTrack("Task 1");
final ITrack track2 = model.createTrack("Task 2");
final ITrack track3 = model.createTrack("Task 3");
final ITrack track4 = model.createTrack("Task 4");

int compTime = 5;
int period = 5;
int lastPosition = 0;
for (int i = 0; i < 4; i++) {
taskLane1.createEvent("", "task 1", lastPosition, compTime,
TimeUnit.MICROSECONDS);
lastPosition += period + compTime;
}
compTime = 2;
period = 2;
lastPosition = 0;
for (int i = 0; i < 10; i++) {
taskLane2.createEvent("", "task 2", lastPosition, compTime,
TimeUnit.MICROSECONDS);
lastPosition += period + compTime;
}
compTime = 2;
period = 2;
lastPosition = 0;
for (int i = 0; i < 10; i++) {
taskLane3.createEvent("", "task 3", lastPosition, compTime,
TimeUnit.MICROSECONDS);
lastPosition += period + compTime;
}
compTime = 2;
