Description

This plugin provides a coverflow component useful for displaying an image set. The component is based on Romain Guy's work explained at http://www.curious-creature.org/2005/07/09/a-music-shelf-in-java2d. In 2008 Kevin Long refactored the code to be more generic and component-like. See http://blog.codebeach.com/2008/02/imageflow-swing-component.html. Finally the components received another face lift in terms of observable properties and the usage of a ListModel to hold the items.

Installation

The current version of griffon-coverflow-plugin is 0.5

To install just issue the following command

Usage

The following nodes will become available on a View script upon installing this plugin

Node	Property	Type	Default	Required	Bindable	Notes
stackLayout [StackLayout]						exposes BOTTOM and TOP as constraints
gradientPanel [GradientPanel]	gradientStart	Color	Color(110, 110, 110)
	gradientEnd	Color	Color(0, 0, 0)
imageFlow [ImageFlow]	items	ImageFlowItem[]				alternate values may be of type List<ImageFlowItem>, ListModel or ImageFlow
	amount	int	5
	sigma	double
	itemFont	Font	Font("Dialog", Font.PLAIN, 24)
	itemTextColor	Color	Color.WHITE
	itemSpacing	double	0.4
imageFlowItem [ImageFlowItem]	file	File				value can be a String. Alternate to url:, image:, inputStream:, resource:
	url	URL				value can be a String. Alternate to file:, image:, inputStream:, resource:
	image	Image				value can be a String. Alternate to file:, url:, inputStream:, resource:
	inputStream	InputStream				Alternate to file:, url:, image:, resource:
	resource	String				Alternate to file:, url:, image:, inputStream:

imageFlowItem can be nested inside imageFlow if and only if the model is mutable.

ImageFlow exposes the following methods to help you navigate and keep track of the current selection:

• previous() - navigates one step backward.
• next() - navigates one step forward.
• getMinSelectionIndex() - returns the smallest selected cell index.
• getMaxSelectionIndex() - returns the largest selected cell index.
• getSelectedIndex() - returns the first selected index; returns -1 if there is no selected item.
• getSelectedValue() - returns the first selected value, or null if the selection is empty.
• isSelectedIndex(int) - returns true if the specified index is selected.
• setSelectedIndex(int) - selects a single cell.
• addListSelectionListener(ListSelectionListener) - adds a listener to the list that's notified each time a change to the selection occur.
• removeListSelectionListener(ListSelectionListener) - removes a listener to the list that's notified each time a change to the selection occur.

The following view script shows a basic usage. Not that imageFlow allows nesting of imageFlowItem given that its defualt model is mutable.
