I want to create a textbox in a group that spans 4 rows. I have tried many
things, but I can't get the text box to be more than one row high.
Here is how I'm creating the box:
group = new Group(composite, SWT.NONE);
group.setText(groupTitle);
layout = new GridLayout();
layout.horizontalSpacing = 15;
layout.numColumns = 1;
group.setLayout(layout);
gridData = new GridData(GridData.FILL_BOTH |
GridData.VERTICAL_ALIGN_CENTER);
gridData.verticalSpan = 4;
group.setLayoutData(gridData);
text = new Text(group, SWT.MULTI | SWT.V_SCROLL | SWT.WRAP);
gridData = new GridData(GridData.FILL_BOTH);
gridData.verticalSpan = 4;
text.setLayoutData(gridData);
What am I doing wrong?

Something like this should work:
int lineHeight = text.getLineHeight();
gridData.heightHint = 4*lineHeight;
text.setLayoutData(gridData);
