style parameter.
For a higher level of control, you can use a custom XML item descriptor as specified through the ItemDescriptor
pseudo-
property (see below for more information).
The items are laid out in a grid, left-to-right and top-to-bottom. The number of columns is determined by the columns
style parameter.
If more galleries exist than fit in the available area, paging controls automatically appear at the bottom of the element. If you want to have complete control over
the appearance of the paging controls, you can specify a custom XML descriptor through the PagingControls
pseudo-property. The speed of the transition between
each page of gallery items is controlled by the scrollTime
parameter. The default status label (if not using a custom paging controls descriptor) is controlled
by the statusLabel
parameter.
By default, when an item in the GallerySelector is clicked the corresponding gallery is opened. If the hideOnSelection
style parameter is left at its default
value of true
, the actual GallerySelector element is hidden as well. You can set this parameter to false
to disable this behavior.
If you wish to use a more compact gallery selection element which appears on the same screen as the images, consider instead the GalleryBar element. It displays a small and unobtrusive bar at the top of the screen which lists the various gallery titles. When hovered over, it displays a tooltip with more information about the gallery.
Layout XML Syntax Example:
The GallerySelector class inherits all of the tag attributes of its superclass.
<GallerySelector Styles columns="2" spacing="10" outerSpacing="Value defined for spacing parameter" displayType="standard|images|imagesHoverTitle" imageHeight="100" transitionTime="1000" scrollTime="1000" statusLabel="Page {N} of {T}" hideOnSelection="true" selectionLayoutView="" selectionDelay="0|1100" Events event_galleryItemClick="Default handler" > Optional Child Descriptor Nodes: (see Pseudo-properties corresponding to node names below) <ItemDescriptor> ... Custom Descriptor Here ... </ItemDescriptor> <PagingControls> ... Custom Descriptor Here ... </PagingControls> </GallerySelector>

ItemDescriptor | property |
public var ItemDescriptor:XML
[Pseudo-property only!] Specifies the XML descriptor used for the creation of the item blocks which represent each gallery. A custom value can be used to customize the appearance of the 'clickable' items which are shown on the GallerySelector.
This is a pseudo-property; it is passed as a child node of the XML node, not as an element attribute. See the class description above for more information / example code.
There are two very important things to note about custom ItemDescriptor
's:
<ItemDescriptor>
node must have only one direct subnode. This container will have its dimensions automatically set based on the columns
style parameter; it is not necessary to specify any dimensions.currentLooperData
object. This provides
a reference to the <gallery>
node for the current gallery. For more information about the Eval{...}
attribute format, see the documentation for the EVAL_EXPRESSION
constant on the XMLAttributeFormats
class.If this property is not explicitly specified, there are three possible default descriptors based on the value of the displayType
style parameter: (1) The "standard"
display which
displays the gallery's thumbnail image, title, and description; (2) The "images"
view, which only displays a large version of the gallery's thumbnail image; (3) The "imagesHoverTitle"
view, which displays a larger gallery thumbnail (with each directly touching the next), and title text that pops up when hovering on an item. The descriptor for the "standard"
display is:

PagingControls | property |
public var PagingControls:XML
[Pseudo-property only!] Specifies the XML descriptor used for the creation of the paging controls (if there is more than one page of galleries to be shown). A custom value can be used to customize the appearance of the paging controls.
This is a pseudo-property; it is passed as a child node of the XML node, not as an element attribute. See the class description above for more information / example code.
If this property is not explicitly specified, the following default descriptor is used:
<PagingControls [Becomes HBox; see below...] paddingTop="10" paddingBottom="10" horizontalAlign="center" verticalAlign="middle" horizontalGap="24"> <Button name="previousButton" skin="ClassReference('com.dwuser.ss4.skins.PreviousButtonSkin')" styleName="GalleryPagingPreviousButton" /> <Label name="pagingLabel" text="statusLabel style value; default = Page {N} of {T}" /> <Button name="nextButton" skin="ClassReference('com.dwuser.ss4.skins.NextButtonSkin')" styleName="GalleryPagingNextButton" /> </PagingControls>
Either way, the descriptor must have at least one child element of the following structure:
<Button name="previousButton" ... />
- This button automatically becomes the "go to previous page" button.<Label name="pagingLabel" text="Page {N} of {T}" ... />
- The text
property on this label will have the following values replaced automatically:
{N}
becomes the current page number; {T}
becomes the total number of pages. Thus, if there were three pages and the first page was visible,
the example label shown above would read "Page 1 of 3". When you don't specify a custom paging controls descriptor, the status label displayed is controlled
by the value of the statusLabel
style parameter.<Button name="nextButton" ... />
- This button automatically becomes the "go to next page" button.Please note! To work properly, the elements must be exactly as shown: a <Button ... />
element named previousButton
, a
<Label ... />
element named pagingLabel
, and a <Button ... />
element named nextButton
.
If you don't use these special names, the correct values won't be automatically displayed.
All paging control elements are held in an HBox
element which is positioned at the bottom of the GallerySelector. Any attributes passed directly on a custom
<PagingControls ... >
descriptor node will be applied to this HBox. Thus, in the example above, custom padding, alignment and spacing has been set.
By default, if no custom descriptor is specified, the "Previous" button inherits any styles defined for the <GalleryPagingPreviousButton ... />
selector in the
<styles>
section of the XML configuration file. Likewise, the "Next" button inherits any styles defined for the <GalleryPagingNextButton ... />
selector, and the status label inherits any styles defined for the <GalleryPagingLabel ... />
selector. These custom style selectors can be used to define customized
styles for the buttons and status label without creating a custom descriptor. However, in some cases it may be easier to just
create a custom paging controls descriptor. For more information about creating these custom style selectors, see the GalleryPagingPreviousButton
, GalleryPagingNextButton
,
and GalleryPagingLable
style selector pseudo-classes; see links below.

galleryItemClick | event |
com.dwuser.ss4.events.SlideshowEvent
com.dwuser.ss4.events.SlideshowEvent.GALLERYITEM_CLICK
The SlideshowEvent.GALLERYITEM_CLICK
constant defines the value of the
type
property of the event object for a galleryItemClick
event.
Dispatched automatically by a GallerySelector
element instance when an item in it is clicked. To create a custom handler for this event,
add a listener for the event on the actual GallerySelector element; see the GallerySelector class for more information.
By default, the built-in handler on the GallerySelector handles the event, opening the corresponding gallery and, if the hideOnSelection
style
parameter is set to true
, hiding the GallerySelector element.
If you wish to prevent the default handler from processing the event, add a custom listener
and call the preventDefault()
method on the event. For example:
// Normally, a custom action would follow the preventDefault() call: <GallerySelector ... event_galleryItemClick="event.preventDefault();" />
Event type: on-globalNotification-only (see SlideshowEvent class description for more information)
The extraInfo
parameter on the event has the following parameters:
Property | Description | Always Present |
---|---|---|
id | The associated gallery's ID index number. This can be used to dispatch a IMAGES_REQUESTGALLERY control event to open the corresponding gallery. | Yes |
