Hi,
I'm trying to set the position of TextViewer in the dialog
which has a GridLayout set.
protected Control createDialogArea(Composite parent)
{
Composite composite = new Composite(parent, SWT.NONE);
GridLayout layout = new GridLayout(1, false);
composite.setLayout(layout);
Label codeLabel = new Label(composite, SWT.NONE);
codeLabel.setText("&Label:");
codeLabel.setLayoutData(new GridData(GridData.BEGINNING,
GridData.BEGINNING, false, false));
codeTextViewer = new TextViewer(getShell(), SWT.MULTI);
codeTextViewer.getControl().setLayoutData(new GridData(450, 100));
codeTextViewer.setInput(new Document());
}
I also have this method:
protected void createButtonsForButtonBar(Composite parent)
{
createButton(parent, IDialogConstants.OK_ID,
IDialogConstants.OK_LABEL, true);
createButton(parent, IDialogConstants.CANCEL_ID,
IDialogConstants.CANCEL_LABEL, false);
}
The trouble is that TextViewer is always set on the bottom end of the
dialog - under the OK, CANCEL buttons! Label 'codeLabel' sits over
the buttons...
I've tried to move the code of the TextViewer around the
createDialogArea method but it had no effect.
It has expected dimensions, but the position is wrong.
Thanks for your replies.

^^^^^^^^^^
codeTextViewer = new TextViewer(composite, SWT.MULTI);

Hello again Tom :-)
I'm afraid I've tried this solution earlier.
That's not the clue. I've left the composite and set getShell()
because the first one didn't work.

This code works perfectly for me on Eclipse-3.2 RC6.
---------------8<---------------
public static void main (String [] args) {
Display display = new Display ();
Shell shell = new Shell (display);
shell.setLayout(new FillLayout());
Dialog dia = new Dialog(shell) {
@Override
protected Control createDialogArea(Composite parent) {
Composite composite = (Composite)super.createDialogArea(parent);
Label codeLabel = new Label(composite, SWT.NONE);
codeLabel.setText("&Label:");
codeLabel.setLayoutData(new
GridData(GridData.BEGINNING,GridData.BEGINNING, false, false));
TextViewer codeTextViewer = new TextViewer(composite, SWT.MULTI);
codeTextViewer.getControl().setLayoutData(new GridData(450, 100));
return composite;
}
};
dia.open();
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}

Well if I replace the super call with the lines below i get the same
result as I got when calling super.

Composite composite = new Composite(parent,SWT.NONE);
composite.setLayout(new GridLayout(1,false));
