Hi,
I have a Table in a composite with GridLayout. Now I want to hide it.
So I do "table.setVisible(false)" and then "shell.pack(true)" (because I
want the dialog resized). I also do a
((GridData)table.getLayoutData()).heightHint = 0 for hiding.
Now the table still occupies its place (well its not as big as it was
before - the heightHint=0 makes it one row high) even though it's not
visible - meaning: the space is not occupied by another control

Hi,
I checked it out. It works.
I'd never come up with the idea of using moveBelow()/moveAbove() for the
needed purpose. The apidoc seems to be quite wrong - or at least it sounds
to me as if I was ordering the controls' position in z-axis direction...

import org.eclipse.swt.events.*;

public class Sample {
private Display display;
private Shell shell;
private Shell invisibleShell;
private Button b;
private Button b1, b2;
Sample() {
display = new Display();
shell = new Shell(display, SWT.DIALOG_TRIM);
invisibleShell = new Shell(display, SWT.NULL);
GridLayout gl = new GridLayout();
shell.setLayout(gl);
b1 = new Button(shell, SWT.NULL);
b1.setText("First; hide");
b1.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
b.setParent(invisibleShell);
shell.pack(true);
}
}
);
b = new Button(shell, SWT.NULL);
b.setText("Middle");
b2 = new Button(shell, SWT.NULL);
b2.setText("Last; show");
b2.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
b.setParent(shell);
b.moveBelow(b1);
shell.pack(true);
}
}

shell.pack();
shell.open();
while(!shell.isDisposed())
display.readAndDispatch();
}
public static void main(String[] args) {
new Sample();
}
}

It works now.
I want the Shell to be resized. The other controls should remain about as
they are.
Using FormLayout is quite painful. Doing it with GridLayout and moving the
Table to an invisible Shell is easier.
It looks like this:
State 1: State2:
---------------- -------------
Some Controls Some Controls
---------------- -------------
Table Other Controls
----------------
Other Controls

On which ones not?
I tested it on Win2k and Linux (with motif, gtk2 and fox) and all those
worked.
