@DefaultProperty("buttonTypes") public class DialogPane extends Pane
DialogPane should be considered to be the root node displayed within a Dialog instance. In this role, the DialogPane is responsible for the placement of headers, graphics, content, and buttons. The default implementation of DialogPane (that is, the DialogPane class itself) handles the layout via the normal Parent.layoutChildren() method. This method may be overridden by subclasses wishing to handle the layout in an alternative fashion).

In addition to the header and content properties, there exists header text and content text properties. The way the *Text properties work is that they are a lower precedence compared to the Node properties, but they are far more convenient for developers in the common case, as it is likely the case that a developer more often than not simply wants to set a string value into the header or content areas of the DialogPane.

It is important to understand the implications of setting non-null values in the header and headerText properties. The key points are as follows:

  1. The header property takes precedence over the headerText property, so if both are set to non-null values, header will be used and headerText will be ignored.
  2. If headerText is set to a non-null value, and a graphic has also been set, the default position for the graphic shifts from being located to the left of the content area to being to the right of the header text.
  3. If header is set to a non-null value, and a graphic has also been set, the graphic is removed from its default position (to the left of the content area), and is not placed to the right of the custom header node. If the graphic is desired, it should be manually added in to the layout of the custom header node manually.

DialogPane operates on the concept of ButtonType. A ButtonType is a descriptor of a single button that should be represented visually in the DialogPane. Developers who create a DialogPane therefore must specify the button types that they want to display, and this is done via the getButtonTypes() method, which returns a modifiable ObservableList, which users can add to and remove from as desired.

The ButtonType class defines a number of pre-defined button types, such as ButtonType.OK and ButtonType.CANCEL. Many users of the JavaFX dialogs API will find that these pre-defined button types meet their needs, particularly due to their built-in support for default and cancel buttons, as well as the benefit of the strings being translated into all languages which JavaFX is translated to. For users that want to define their own ButtonType (most commonly to define a button with custom text), they may do so via the constructors available on the ButtonType class.

Developers will quickly find that the amount of configurability offered via the ButtonType class is minimal. This is intentional, but does not mean that developers can not modify the buttons created by the ButtonType that have been specified. To do this, developers simply call the lookupButton(ButtonType) method with the ButtonType (assuming it has already been set in the getButtonTypes() list. The returned Node is typically of type Button, but this depends on if the createButton(ButtonType) method has been overridden.

The DialogPane class offers a few methods that can be overridden by subclasses, to more easily enable custom functionality. These methods include the following:

  • createButton(ButtonType)
  • createDetailsButton()
  • createButtonBar()

These methods are documented, so please take note of the expectations placed on any developer who wishes to override these methods with their own functionality.

header

public final ObjectProperty<Node> headerProperty
Property representing the header area of the dialog pane. Note that if this header is set to a non-null value, that it will take up the entire top area of the DialogPane. It will also result in the DialogPane switching its layout to the 'header' layout - as outlined in the DialogPane class javadoc.
See Also:
  • getHeader()

Sets the dialog expandable content node, or null if no expandable content needs to be shown.
Parameters:
content - the dialog expandable content node

expandedProperty

public final BooleanProperty expandedProperty()
Represents whether the dialogPane is expanded.
Returns:
the property representing whether the dialogPane is expanded
See Also:
  • isExpanded()
  • setExpanded(boolean)

isExpanded

public final boolean isExpanded()
Returns whether or not the dialogPane is expanded.
Returns:
true if dialogPane is expanded.

setExpanded

public final void setExpanded(boolean value)
Sets whether the dialogPane is expanded. This only makes sense when there is expandable content to show.
Parameters:
value - true if dialogPane should be expanded.

getButtonTypes

public final ObservableList<ButtonType> getButtonTypes()
Observable list of button types used for the dialog button bar area (created via the createButtonBar() method). Modifying the contents of this list will immediately change the buttons displayed to the user within the dialog pane.
Returns:
The ObservableList of button types available to the user.

lookupButton

public final Node lookupButton(ButtonType buttonType)
This method provides a way in which developers may retrieve the actual Node for a given ButtonType (assuming it is part of the button types list).
Parameters:
buttonType - The ButtonType for which a Node representation is requested.
Returns:
The Node used to represent the button type, as created by createButton(ButtonType), and only if the button type is part of the button types list, otherwise null.

createButtonBar

protected Node createButtonBar()
This method can be overridden by subclasses to provide the button bar. Note that by overriding this method, the developer must take on multiple responsibilities:
  1. The developer must immediately iterate through all button types and call createButton(ButtonType) for each of them in turn.
  2. The developer must add a listener to the button types list, and when this list changes update the button bar as appropriate.
  3. Similarly, the developer must watch for changes to the expandable content property, adding and removing the details button (created via createDetailsButton() method).

The default implementation of this method creates and returns a new ButtonBar instance.

Returns:
the created button bar

createButton

protected Node createButton(ButtonType buttonType)
This method can be overridden by subclasses to create a custom button that will subsequently inserted into the DialogPane button area (created via the createButtonBar() method, but mostly commonly it is an instance of ButtonBar.
Parameters:
buttonType - The ButtonType to create a button from.
Returns:
A JavaFX Node that represents the given ButtonType, most commonly an instance of Button.

createDetailsButton

protected Node createDetailsButton()
This method can be overridden by subclasses to create a custom details button.

To override this method you must do two things:

  1. The button will need to have its own code set to handle mouse / keyboard interaction and to toggle the state of the expanded property.
  2. If your button changes its visuals based on whether the dialog pane is expanded or collapsed, you should add a listener to the expanded property, so that you may update the button visuals.
Returns:
the created details button

getClassCssMetaData

public static List<CssMetaData<? extends Styleable,?>> getClassCssMetaData()
Gets the CssMetaData associated with this class, which may include the CssMetaData of its superclasses.
Returns:
the CssMetaData
