Hi,
I've got a View that displays some Attributes of an Object,
like Length, Width etc. I wanted to do this with Eclipse Forms,
so I created a Section whose body is a Composite with a
GridLayout(3, false). I have the name of the Field in the 1st column,
a text-widget in 2nd, and a unit in the 3rd. (see attached screenshot).
Between the first two columnsthere should be a bigger spacing,
while between the last two there only should be a small spacing.
I use GridData.horizontalIndent with a negatiove-value on the last
column for this, but it only seems to work for up to two rows.
starting with the 3rd row, it looks like my screenshot.
It works in a non-Forms View and also in a Forms-View using
a TableWrapLayout.
Whats the problem here with GridLayout?
thanks,
Manuel

It's hard to diagnose the problem without any code, but if I wanted to
produce the layout you describe I would start by setting the
GridLayout's horizontal spacing to 0 and then specify a positive
horizontalIndent on the Text, which will offset it from the first label.
Here's a snippet of code as an example:
(This code was easily produced using the SWT Layout example tool from
the SWT Examples project http://www.eclipse.org/swt/examples.php)
import org.eclipse.swt.*;
import org.eclipse.swt.custom.*;
import org.eclipse.swt.graphics.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;
public class MyLayout {
public static void main (String [] args) {
Display display = new Display ();
Shell shell = new Shell (display);
GridLayout gridLayout = new GridLayout ();
gridLayout.numColumns = 3;
gridLayout.horizontalSpacing = 0;
shell.setLayout (gridLayout);
Label label0 = new Label (shell, SWT.NONE);
label0.setText ("label0");
Text text1 = new Text (shell, SWT.BORDER);
text1.setText ("text1");
GridData data = new GridData ();
data.horizontalAlignment = GridData.FILL;
data.horizontalIndent = 25;
data.grabExcessHorizontalSpace = true;
text1.setLayoutData (data);
Label label2 = new Label (shell, SWT.NONE);
label2.setText ("label2");
shell.pack ();
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ())
display.sleep ();
}
display.dispose ();
}
}
