public abstract class AbstractFormBuilder<B extends AbstractFormBuilder<B>> extends AbstractBuilder<B>
An abstract class that minimizes the effort required to implement non-visual builders that use the FormLayout.

Builders hide details of the FormLayout and provide convenience behavior that assists you in constructing a form. This class provides a cell cursor that helps you traverse a form while you add components. Also, it offers several methods to append custom and logical columns and rows.

      Returns:
      the builder's current CellConstraints object
    • getLeadingColumn

      protected int getLeadingColumn()
      Returns the index of the leading column.

      Returns:
      the leading column
    • getColumnIncrementSign

      protected final int getColumnIncrementSign()
      Returns the sign (-1 or 1) used to increment the cursor's column when moving to the next column.
