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");
