the class GridController method dynamicDisplay.

//  propertyChange
/**
	 *  Dynamic Display.
	 *  - Single Row Screen layout and update of dynamic Lookups
	 *  <p>
	 *  Single Row layout:
	 *  the components's name is the ColumnName; if it matches, the
	 *  MField.isDisplayed(true) is used to determine if it is visible
	 *  if the component is a VEditor, setEnabled is set from the MField
	 *  <p>
	 *  Multi Row layout is not changed:
	 *  VCellRenderer calls JTable.isCellEditable -> checks MField.isEditable (Active, isDisplayed)
	 *  VCellEditor.isCellEditable calls MField.isEditable(true) <br>
	 *  If a column is not displayed, the width is set to 0 in dynInit
	 *  <p>
	 *  Dynamic update of data is handeled in VLookup.focusGained/Lost.
	 *  When focus is gained the model is temporarily updated with the
	 *  specific validated data, if lost, it is switched back to the
	 *  unvalidated data (i.e. everything). This allows that the display
	 *  methods have a lookup to display. <br>
	 *  Here: if the changed field has dependents and the dependent
	 *  is a Lookup and this lookup has a dynamic dependence of the changed field,
	 *  the value of that field is set to null (in MTab.processDependencies -
	 *  otherwise it would show an invalid value).
	 *  As Editors listen for value changed of their MField, the display is updated.
	 *  <p>
	 *  Called from GridController.valueChanged/dataStatusChanged, APane;.stateChanged/unlock/cmd_...
	 *  @param col selective column number or 0 if all
