## Class FormDebugUtils

- java.lang.Object
- - com.jgoodies.forms.debug.FormDebugUtils

-     public final class FormDebugUtils
      extends Object

  Provides static methods that help you understand and fix layout problems when using the `FormLayout`. Dumps information about the layout grid, layout groups and cell constraints to the console.

  Implicit values are mapped to concrete. For example, implicit alignments in column and row specifications will be visible. And cell constraint alignments that use or override the column and row defaults are visible too.

       ColumnSpec("p")   -> ColumnSpec("fill:pref:0");
       ColumnSpec("p:1") -> ColumnSpec("fill:pref:1");

       RowSpec("p")      -> RowSpec("center:pref:0");
       RowSpec("p:1")    -> RowSpec("center:pref:1");

      Parameters:
        `container` - the layout container

    - #### dumpColumnSpecs

          public static void dumpColumnSpecs(FormLayout layout)

      Dumps the layout's column specifications to the console.
      Parameters:
        `layout` - the `FormLayout` to inspect

    - #### dumpRowSpecs

          public static void dumpRowSpecs(FormLayout layout)

      Dumps the layout's row specifications to the console.
      Parameters:
        `layout` - the `FormLayout` to inspect

    - #### dumpColumnGroups

          public static void dumpColumnGroups(FormLayout layout)

      Dumps the layout's column groups to the console.
      Parameters:
