FormData

Instances of this class are used to define the attachments of a control in a <code>FormLayout</code>. <p> To set a <code>FormData</code> object into a control, you use the <code>setLayoutData ()</code> method. To define attachments for the <code>FormData</code>, set the fields directly, like this: <pre> FormData data = new FormData(); data.left = new FormAttachment(0,5); data.right = new FormAttachment(100,-5); button.setLayoutData(formData); </pre> </p> <p> <code>FormData</code> contains the <code>FormAttachments</code> for each edge of the control that the <code>FormLayout</code> uses to determine the size and position of the control. <code>FormData</code> objects also allow you to set the width and height of controls within a <code>FormLayout</code>. </p>

Variables

bottom FormAttachment bottom;: bottom specifies the attachment of the bottom of the control.
cacheBottom FormAttachment cacheBottom;
cacheHeight int cacheHeight;: Undocumented in source.
cacheLeft FormAttachment cacheLeft;
cacheRight FormAttachment cacheRight;
cacheTop FormAttachment cacheTop;: Undocumented in source.
cacheWidth int cacheWidth;
currentHeight int currentHeight;
currentHhint int currentHhint;: Undocumented in source.

currentWidth int currentWidth;
defaultHeight int defaultHeight;
defaultHhint int defaultHhint;: Undocumented in source.
defaultWhint int defaultWhint;
defaultWidth int defaultWidth;: Undocumented in source.
height int height;: height specifies the preferred height in pixels. This value is the hHint passed into Control.computeSize(int, int, bool) to determine the preferred size of the control.

left FormAttachment left;: left specifies the attachment of the left side of the control.
needed bool needed;: Undocumented in source.
right FormAttachment right;: right specifies the attachment of the right side of the control.
top FormAttachment top;: top specifies the attachment of the top of the control.
width int width;: width specifies the preferred width in pixels. This value is the wHint passed into Control.computeSize(int, int, bool) to determine the preferred size of the control.
