      • buildInlineEditorComponent

        protected java.awt.Component buildInlineEditorComponent()
        Delegate the construction of the inline editor component.

        This editor provides a panel containing a TaskMonitorComponent and the ability to reload the columns' data; if the delegate editor provides an inline editor, this wraps it, and switches between task view and the editor depending on the executing state of the data-load task.

        Specified by:
        buildInlineEditorComponent in class AbstractColumnConstraintEditor<T>
        the editors inline component

      • buildDelegateInlineEditor

        protected java.awt.Component buildDelegateInlineEditor()
        Get the delegates' inline editor component
        the inline editor for the delegate constraint
      • buildDetailEditorComponent

        protected java.awt.Component buildDetailEditorComponent()
        Delegate the construction of the detail editor component.

        Subclasses should override this method if they choose to provide a detailed constraint editor. This is an optional feature, and this implementation returns null to satisfy the ColumnConstraintEditor contract.

        buildDetailEditorComponent in class AbstractColumnConstraintEditor<T>
        the editors detail component; null in this implementation
