Dialog layout and resize problem [message #458257] Tue, 12 July 2005 12:56 Go to next message

Hi,

I have a resizable dialog (extending org.eclipse.jface.dialogs.Dialog)
that contains several input values. Here's a part of the code:

===================
...

//Create composite
Composite composite = ... ; //creates a composite for fields in the
dialog.
GridLayout layout = new GridLayout();
layout.numColumns = 2;
layout.makeColumnsEqualWidth = false;
composite.setLayout(layout);

//Create labels and fields:
Label nameLabel = new Label(composite,SWT.NONE);
nameLabel.setText("Name:");
nameText = new Text(composite, SWT.SINGLE | SWT.BORDER);
nameText.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
Label linkLabel = new Label(composite,SWT.NONE);
linkLabel.setText("Link:");
linkText = new Text(composite, SWT.SINGLE | SWT.BORDER);
linkText.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));

...
====================

Problem is that when a user makes the dialog wider, both columns of the
layout get wider, i.e. excess empty space between the end of the labels
and beginning of the fields grows as well. How to make only the second
column (the fields column), get wider, and the width of the first coulmn
(the labels column) always stay the same? I haven't so far figured that
out...

Thanks in advance :)

Hi,

Use GridData.GRAB_HORIZONTAL style bit for the second column

Hi,

Seems to not work, the GridData.FILL_HORIZONTAL i'm using is actually
HORIZONTAL_ALIGN_FILL | GRAB_HORIZONTAL.

Yes, you're right, I forgot that.
I made a simple snippet and it's working with SWT version 3.063.

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

/**
* @author Robert Bacs
*/
public class ShellTest {
public static void main (String [] args) {
final Display display = new Display ();
final Shell shell = new Shell (display);
shell.setLayout(new FillLayout());
Composite c = new Composite(shell, SWT.NONE);
c.setLayout(new GridLayout(2, false));
Label nameLabel = new Label(c, SWT.NONE);
nameLabel.setText("Name:");
Text nameText = new Text(c, SWT.SINGLE | SWT.BORDER);
GridData gd = new GridData(GridData.FILL_HORIZONTAL);
nameText.setLayoutData(gd);
Label linkLabel = new Label(c, SWT.NONE);
linkLabel.setText("Link:");
Text linkText = new Text(c, SWT.SINGLE | SWT.BORDER);
gd = new GridData(GridData.FILL_HORIZONTAL);
linkText.setLayoutData(gd);

shell.pack ();
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
}
