Eclipse Rich Ajax Platform
Release 1.2

org.eclipse.swt.layout
Class FormData

java.lang.Object
  extended by
org.eclipse.swt.layout.FormData

public final class FormData
extends Object

Instances of this class are used to define the attachments of a control in a FormLayout.

To set a FormData object into a control, you use the setLayoutData () method. To define attachments for the FormData, set the fields directly, like this:

    FormData data = new FormData();
    data.left = new FormAttachment(0,5);
    data.right = new FormAttachment(100,-5);
    button.setLayoutData(formData);
 

FormData contains the FormAttachments for each edge of the control that the FormLayout uses to determine the size and position of the control. FormData objects also allow you to set the width and height of controls within a FormLayout.

Since:
1.0
