Class DefaultFormBuilder


  • public final class DefaultFormBuilder
    extends I15dPanelBuilder
    Provides a means to build form-oriented panels quickly and consistently using the FormLayout. This builder combines frequently used panel building steps: add a new row, add a label, proceed to the next data column, then add a component.

    The extra value lies in the #append methods that append gap rows and component rows if necessary and then add the given components. They are built upon the superclass behavior #appendRow and the set of #add methods. A set of component appenders allows to add a textual label and associated component in a single step.

    This builder can map resource keys to internationalized (i15d) texts when creating text labels, titles and titled separators. Therefore you must specify a ResourceBundle in the constructor. The builder methods throw an IllegalStateException if one of the mapping builder methods is invoked and no bundle has been set.

    You can configure the build process by setting a leading column, enabling the row grouping and by modifying the gaps between normal lines and between paragraphs. The leading column will be honored if the cursor proceeds to the next row. All appended components start in the specified lead column, except appended separators that span all columns.

    It is temptive to use the DefaultFormBuilder all the time and to let it add rows automatically. Use a simpler style if it increases the code readability. Explicit row specifications and cell constraints make your layout easier to understand - but harder to maintain. See also the accompanying tutorial sources and the Tips & Tricks that are part of the Forms documentation.

    Sometimes a form consists of many standardized rows but has a few rows that require a customization. The DefaultFormBuilder can do everything that the superclasses AbstractFormBuilder and PanelBuilder can do; among other things: appending new rows and moving the cursor. Again, ask yourself if the DefaultFormBuilder is the appropriate builder. As a rule of thumb you should have more components than builder commands. There are different ways to add custom rows. Find below example code that presents and compares the pros and cons of three approaches.

    The texts for labels and titles can be marked texts, i.e. strings with an optional mnemonic marker. See the MnemonicUtils class comment for details.

    Example:

     public void build() {
         FormLayout layout = new FormLayout(
             "right:max(40dlu;pref), 3dlu, 80dlu, 7dlu, " // 1st major colum
           + "right:max(40dlu;pref), 3dlu, 80dlu",        // 2nd major column
             "");                                         // add rows dynamically
         DefaultFormBuilder builder = new DefaultFormBuilder(layout)
                    .border(Borders.DIALOG);
    
         builder.appendSeparator("Flange");
    
         builder.append("Identifier", identifierField);
         builder.nextLine();
    
         builder.append("PTI [kW]",   new JTextField());
         builder.append("Power [kW]", new JTextField());
    
         builder.append("s [mm]",     new JTextField());
         builder.nextLine();
    
         builder.appendSeparator("Diameters");
    
         builder.append("da [mm]",    new JTextField());
         builder.append("di [mm]",    new JTextField());
    
         builder.append("da2 [mm]",   new JTextField());
         builder.append("di2 [mm]",   new JTextField());
    
         builder.append("R [mm]",     new JTextField());
         builder.append("D [mm]",     new JTextField());
    
         builder.appendSeparator("Criteria");
    
         builder.append("Location",   buildLocationComboBox());
         builder.append("k-factor",   new JTextField());
    
         builder.appendSeparator("Bolts");
    
         builder.append("Material",   ViewerUIFactory.buildMaterialComboBox());
         builder.nextLine();
    
         builder.append("Numbers",    new JTextField());
         builder.nextLine();
    
         builder.append("ds [mm]",    new JTextField());
     }
     

    Custom Row Example:

     public JComponent buildPanel() {
         initComponents();
    
         FormLayout layout = new FormLayout(
                 "right:pref, 3dlu, default:grow",
                 "");
         DefaultFormBuilder builder = new DefaultFormBuilder(layout)
                .border(Borders.DIALOG)
              .rowGroupingEnabled(true);
    
         // In this approach, we add a gap and a custom row.
         // The advantage of this approach is, that we can express
         // the row spec and comment area cell constraints freely.
         // The disadvantage is the misalignment of the leading label.
         // Also the row's height may be inconsistent with other rows.
         builder.appendSeparator("Single Custom Row");
         builder.append("Name", name1Field);
         builder.appendLineGapRow();
         builder.appendRow(RowSpec.decode("top:31dlu")); // Assumes line is 14, gap is 3
         builder.nextLine(2);
         builder.append("Comment");
         builder.add(new JScrollPane(comment1Area),
                     CC.xy(builder.getColumn(), builder.getRow(), "fill, fill"));
         builder.nextLine();
    
         // In this approach, we append a standard row with gap before it.
         // The advantage is, that the leading label is aligned well.
         // The disadvantage is that the comment area now spans
         // multiple cells and is slightly less flexible.
         // Also the row's height may be inconsistent with other rows.
         builder.appendSeparator("Standard + Custom Row");
         builder.append("Name", name2Field);
         builder.append("Comment");
         builder.appendRow(RowSpec.decode("17dlu")); // Assumes line is 14, gap is 3
         builder.add(new JScrollPane(comment2Area),
                     CC.xywh(builder.getColumn(), builder.getRow(), 1, 2));
         builder.nextLine(2);
    
         // In this approach, we append two standard rows with associated gaps.
         // The advantage is, that the leading label is aligned well,
         // and the height is consistent with other rows.
         // The disadvantage is that the comment area now spans
         // multiple cells and is slightly less flexible.
         builder.appendSeparator("Two Standard Rows");
         builder.append("Name", name3Field);
         builder.append("Comment");
         builder.nextLine();
         builder.append("");
         builder.nextRow(-2);
         builder.add(new JScrollPane(comment3Area),
                     CC.xywh(builder.getColumn(), builder.getRow(), 1, 3));
    
         return builder.build();
     }
     

    TODO: Consider adding a method for appending a component that spans the remaining columns in the current row. Method name candidates are #appendFullSpan and #appendRemaining.
