Class FormData
java.lang.Object
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.
