Class TableVec

java.lang.Object
  tablelayout.TableVec

Direct Known Subclasses:

TableCol, TableRow

public abstract class TableVec
extends Object

Each TableLayout Manager has two TableVectors: one describes the columns, and the other describes the rows. The TableVector is an abstract class. For the column use TableCol, for the row use TableRow. The table vector is created, based on information of the layout of the TableLayout Manager, hence they must be created after the layout, and they must be updated when the layout changes. The TableVec is an array of TableVecRec, which contains the size information of each component in a row of column.
