How to change the size of a Shell? [message #465550] Thu, 15 December 2005 02:57 Go to next message

Hi, friends,
I am developing a plug-in and wants a dialog to be opened when a
button is clicked. However, when the dialog opens, it is too
small. I want to enlarge the size of the dialog by resizing the
Shell. But Shell.setSize(width,length) seems does not work.

My code is as follows:

final Shell shell =
new Shell(parent, SWT.DIALOG_TRIM | SWT.TITLE |SWT.BORDER
|SWT.APPLICATION_MODAL);

shell.setText("Connect to Server");
shell.setSize(500,200);
shell.setLayout(new GridLayout(2, true));

shell.setSize(500,200) has no effect on the size of the Shell. The
dialog remains the original small size.

Anyone knows what goes wrong here? Or some other methods to change the
size of a shell?

Thanks!

Lijuan

Lijuan,
It is correct method - you add any component in shell which change
size of shell - maybe jface dialog or similar

I set labels,texts and buttons on the shell to form a dialog. But don't
want to use any predefined dialog class in Jface.

If the size of a text box can be changed, then the shell size might be
changed? But how to resize a text box?

Calling layout() on the composite containing the text box should
resize the text box to it's preferred size (based on your layout data).

The following works for me:

public static void main (String [] args) {
Display display = new Display ();
Shell parent = new Shell (display);
parent.setText("Parent shell");
parent.setSize(300, 300);
parent.open ();

final Shell shell = new Shell(parent, SWT.DIALOG_TRIM | SWT.TITLE
|SWT.BORDER |SWT.APPLICATION_MODAL);
shell.setText("Connect to Server");
shell.setLayout(new GridLayout(2, true));
Label l = new Label(shell, SWT.NONE);
l.setText("click button to resize dialog");
l.setLayoutData(new GridData(SWT.FILL, SWT.TOP, true, false));
Button b = new Button(shell, SWT.PUSH);
b.setText("resize dialog");
b.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event e) {
Point size = shell.getSize();
shell.setSize(size.x+10, size.y + 10);
}
});
shell.setSize(500,200);
shell.open();

while (!parent.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}

Thanks, it works by calling:

text.setText("A String");
shell.layout();
The text box will be resized to the prefered size.

However, "A String" does not appear in the text box as default value,
why? and how to set a default value in a text box?

Thanks,
Lijuan
