Class AbstractI15dPanelBuilder

public abstract class AbstractI15dPanelBuilder extends PanelBuilder

An abstract panel builder class that uses the FormLayout to lay out JPanels. In addition to its superclass PanelBuilder this class provides convenience behavior to map resource keys to their associated internationalized (i15d) strings when adding labels, titles and titled separators.

The localized texts used in methods #addI15dLabel and #addI15dTitle 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".

For debugging purposes you can automatically set a tooltip for the created labels that show its resource key. In case of an inproper resource localization, the label will show the wrong text, and the tooltip will help you identify the resource key with the broken localization. This feature can be enabled by calling setDebugToolTipsEnabled. If you want to enable it in a deployed application, you can set the system parameter I15dPanelBuilder.debugToolTipsEnabled to "true".

Subclasses must implement the conversion from resource key to the localized string in #getI15dString(String). For example class I15dPanelBuilder gets a ResourceBundle on construction, and requests strings from that bundle.

Constructor Detail

AbstractI15dPanelBuilder

protected AbstractI15dPanelBuilder(FormLayout layout)
Constructs an AbstractI15dPanelBuilder for the given layout. Uses an instance of JPanel as layout container.

Parameters: layout the FormLayout used to layout the container

AbstractI15dPanelBuilder

protected AbstractI15dPanelBuilder(FormLayout layout, JPanel panel)
Constructs an AbstractI15dPanelBuilder for the given FormLayout and layout container.

Parameters: layout the FormLayout used to layout the container panel the layout container

Method Detail

addI15dLabel

public final JLabel addI15dLabel(String resourceKey, CellConstraints constraints)
Adds an internationalized (i15d) textual label to the form using the specified constraints.

Parameters: resourceKey the resource key for the label's text constraints the label's cell constraints

Returns: the added label

addI15dLabel

public final JLabel addI15dLabel(String resourceKey, String encodedConstraints)
Adds an internationalized (i15d) textual label to the form using the specified constraints.

Parameters: resourceKey the resource key for the label's text encodedConstraints a string representation for the constraints

Returns: the added label

addI15dLabel

public final JLabel addI15dLabel(String resourceKey, CellConstraints labelConstraints, Component component, CellConstraints componentConstraints)
Adds an internationalized (i15d) label and component to the panel using the given cell constraints. Sets the 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.add("name.key", 
             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.add("name.key", 
             cc.xy(1, 7).clone(), // cloned before the next modification 
             nameField, 
             cc.xy(3, 7)          // sets this instance to (3, 7)
            );
 

Parameters: resourceKey the resource key for the label 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)

addI15dSeparator

public final JComponent addI15dSeparator(String resourceKey, CellConstraints constraints)
Adds an internationalized (i15d) titled separator to the form using the specified constraints.

Parameters: resourceKey the resource key for the separator title constraints the separator's cell constraints

Returns: the added titled separator

addI15dSeparator

public final JComponent addI15dSeparator(String resourceKey, String encodedConstraints)
Adds an internationalized (i15d) titled separator to the form using the specified constraints.

Parameters: resourceKey the resource key for the separator titel encodedConstraints a string representation for the constraints

Returns: the added titled separator

addI15dTitle

public final JLabel addI15dTitle(String resourceKey, CellConstraints constraints)
Adds a title to the form using the specified constraints.

Parameters: resourceKey the resource key for the separator title constraints the separator's cell constraints

Returns: the added title label

addI15dTitle

public final JLabel addI15dTitle(String resourceKey, String encodedConstraints)
Adds a title to the form using the specified constraints.

Parameters: resourceKey the resource key for the separator titel encodedConstraints a string representation for the constraints

getI15dString

protected abstract String getI15dString(String resourceKey)
Looks up and returns the internationalized (i15d) string for the given resource key from the ResourceMap.

Parameters: resourceKey the key to look for in the resource map

Returns: the associated internationalized string, or the resource key itself in case of a missing resource
