Hello All,

Goal: Create a JFace dialog with a SWT text widget and the okay and cancel
buttons such that when the user types text, the dialog and the text area
expand/shrink according to the width and height of the text.

private Text textArea;

I am using a gridlayout:
textArea.setLayoutData(new GridData(GridData.FILL_BOTH));

I can get the textarea to expand/shrink using the following code:
textArea.setSize(textArea.computeSize(SWT.DEFAULT, SWT.DEFAULT));

I have put this code in the modify event of the textarea. But I think
there might be a better place to put this. Any ideas?
I could not find a way to shrink/expand the dialog. The only place where I
can set the size of the dialog is in the configureShell(Shell shell)
function. But this sets the size only once when creating the dialog.

I also tried to do the following in the createContents(composite parent)
function:
getShell().setSize(getShell().computeSize(SWT.DEFAULT, SWT.DEFAULT));

this also sets the size once. How do I resize the dialog and keep it in
sync with the textarea. It is better in this case to use just a shell? and
not a JFace dialog?

Thanks.

Looking at the implementation of Window.getInitialSize() (which Dialog
inherits and uses), it looks like you can just call shell.computeSize()
as it does, whenever the Text size has changed.

Hope this helps,
Eric

Thanks for the response Eric.

I do shell.setSize(shell.computeSize(SWT.DEFAULT, SWT.DEFAULT)); when the
text changes and it seems to be working.
