java.lang.Objectorg.eclipse.swt.widgets.Layout
org.eclipse.jface.layout.AbstractColumnLayout
org.eclipse.jface.layout.TableColumnLayout
The TableColumnLayout is the Layout used to maintain
TableColumn sizes in a Table.
You can only add the Layout to a container whose only
child is the Table control you want the Layout applied to.
Don't assign the layout directly the Table

protected Point computeSize(Composite composite,
int wHint,
int hHint,
boolean flushCache)
LayoutThis method computes the size that the client area of the composite must be in order to position all children at their preferred size inside the composite according to the layout algorithm encoded by this layout.
When a width or height hint is supplied, it is used to constrain the result. For example, if a width hint is provided that is less than the width of the client area, the layout may choose to wrap and increase height, clip, overlap, or otherwise constrain the children.

protected void layout(Composite composite,
boolean flushCache)
LayoutThis method positions and sizes the children of a composite using the layout algorithm encoded by this layout. Children of the composite are positioned in the client area of the composite. The position of the composite is not altered by this method.
When the flush cache hint is true, the layout is instructed to flush any cached values associated with the children. Typically, a layout will cache the preferred sizes of the children to avoid the expense of computing these values each time the widget is laid out.
When layout is triggered explicitly by the programmer the flush cache hint is true. When layout is triggered by a resize, either caused by the programmer or by the user, the hint is false.
