public class PanelBuilder
extends AbstractFormBuilder

An general purpose panel builder that uses the FormLayout to lay out JPanels. It provides convenience methods to set a default border and to add labels, titles and titled separators.

The PanelBuilder is the working horse for layouts when more specialized builders like the ButtonBarBuilder or DefaultFormBuilder are inappropriate.

The Forms tutorial includes several examples that present and compare different style to build with the PanelBuilder: static row numbers vs. row variable, explicit CellConstraints vs. builder cursor, static rows vs. dynamically added rows. Also, you may check out the Tips & Tricks section of the Forms HTML documentation.

The text arguments passed to the methods #addLabel, #addTitle, and #addSeparator can contain an optional mnemonic marker. The mnemonic and mnemonic index are indicated by a single ampersand (&). For example "&Save", or "Save &as". To use the ampersand itself duplicate it, for example "Look&&Feel".

Example:
This example creates a panel with 3 columns and 3 rows.

 FormLayout layout = new FormLayout(
      "pref, $lcgap, 50dlu, $rgap, default",  // columns
      "pref, $lg, pref, $lg, pref");          // rows

 PanelBuilder builder = new PanelBuilder(layout);
 builder.addLabel("&Title:",        CC.xy  (1, 1));
 builder.add(new JTextField(),      CC.xywh(3, 1, 3, 1));
 builder.addLabel("&Price:",        CC.xy  (1, 3));
 builder.add(new JTextField(),      CC.xy  (3, 3));
 builder.addLabel("&Author:",       CC.xy  (1, 5));
 builder.add(new JTextField(),      CC.xy  (3, 5));
 builder.add(new JButton("?"), CC.xy  (5, 5));
 return builder.getPanel();

Throws:

NullPointerException - if layout or container is null

Method Detail

getLabelForFeatureEnabledDefault

public static boolean getLabelForFeatureEnabledDefault()

Returns the global default for the enablement of the setLabelFor feature. This can be overridden per PanelBuilder using labelForFeatureEnabled(boolean). The feature is globally disabled by default.

Returns:

true for globally enabled, false for globally disabled

setLabelForFeatureEnabledDefault

public static void setLabelForFeatureEnabledDefault(boolean b)

Sets the default value for the setLabelFor feature enablement. This can be overridden per PanelBuilder using labelForFeatureEnabled(boolean). The default value is used to set the initial PanelBuilder setting for this feature. The feature is globally disabled by default.

Parameters:

ComponentFactory

addLabel

public final JLabel addLabel(String textWithMnemonic,
                             CellConstraints constraints)

Adds a textual label to the form using the specified constraints.

 addLabel("Name:",       CC.xy(1, 1)); // No Mnemonic

 addLabel("Save &as:",   CC.xy(1, 1)); // Mnemonic is the second 'a'
 addLabel("Look&&Feel:", CC.xy(1, 1)); // No mnemonic, text is "look&feel"
 

Parameters:

textWithMnemonic - the label's text - may contain an ampersand (&) to mark a mnemonic

constraints - the label's cell constraints

Returns:

the new label

See Also:

ComponentFactory

addLabel

public final JLabel addLabel(String textWithMnemonic,
                             String encodedConstraints)

Adds a textual label to the form using the specified constraints.

 addLabel("Name:",       "1, 1"); // No Mnemonic
 addLabel("N&ame:",      "1, 1"); // Mnemonic is 'a'
 addLabel("Save &as:",   "1, 1"); // Mnemonic is the second 'a'
 addLabel("Look&&Feel:", "1, 1"); // No mnemonic, text is "look&feel"
 

Parameters:

textWithMnemonic - the label's text - may contain an ampersand (&) to mark a mnemonic

encodedConstraints - a string representation for the constraints

Returns:

the new label

See Also:

ComponentFactory

addLabel

public final JLabel addLabel(String textWithMnemonic,
                             CellConstraints labelConstraints,
                             Component component,
                             CellConstraints componentConstraints)

Adds a label and component to the panel using the given cell constraints. Sets the given label as the component label using JLabel.setLabelFor(java.awt.Component).

Note: The CellConstraints objects for the label and the component must be different. Cell constraints are implicitly cloned by the FormLayout when added to the container. However, in this case you may be tempted to reuse a CellConstraints object in the same way as with many other builder methods that require a single CellConstraints parameter. The pitfall is that the methods CellConstraints.xy*(...) just set the coordinates but do not create a new instance. And so the second invocation of xy*(...) overrides the settings performed in the first invocation before the object is cloned by the FormLayout.

Wrong:

 builder.addLabel(
     "&Name:",            // Mnemonic is 'N'
     cc.xy(1, 7),         // will be modified by the code below
     nameField,
     cc.xy(3, 7)          // sets the single instance to (3, 7)
 );
 

Correct:

 builder.addLabel(
     "&Name:",
     CC.xy(1, 7),         // creates an instance
     nameField,
     CC.xy(3, 7)          // creates another instance
 );
 

Parameters:

textWithMnemonic - the label's text - may contain an ampersand (&) to mark a mnemonic

labelConstraints - the label's cell constraints

component - the component to add

componentConstraints - the component's cell constraints

Returns:

the added label

Throws:

IllegalArgumentException - if the same cell constraints instance is used for the label and the component

See Also:

JLabel.setLabelFor(java.awt.Component), ComponentFactory, DefaultFormBuilder

     CC.xy(3, 7)          // creates another instance
 );
 

Parameters:

label - the label to add

labelConstraints - the label's cell constraints

component - the component to add

componentConstraints - the component's cell constraints

Returns:

the added label

Throws:

IllegalArgumentException - if the same cell constraints instance is used for the label and the component

JLabel.setLabelFor(java.awt.Component), DefaultFormBuilder

add

public Component add(Component component,
                     CellConstraints cellConstraints)

Adds a component to the panel using the given cell constraints. In addition to the superclass behavior, this implementation tracks the most recently added label, and associates it with the next added component that is applicable for being set as component for the label.

Overrides:

add in class AbstractFormBuilder

Parameters:

component - the component to add

cellConstraints - the component's cell constraints

Returns:

the added component

See Also:

Checks and answers whether the given component shall be set as component for a previously added label using JLabel.setLabelFor(Component). This default implementation checks whether the component is focusable, and - if a JComponent - whether it is already labeled by a JLabel. Subclasses may override.

Parameters:

label - the candidate for labeling component

component - the component that could be labeled by label

Returns:

true if focusable, false otherwise

setLabelFor

protected void setLabelFor(JLabel label,
