Enclosing class:

ThumbnailPanel

public static class ThumbnailPanel.View
extends JPanel
implements Scrollable, DocumentPanelListener, Autoscroll, PropertyChangeListener, DropTargetListener, Runnable

This class is the JPanel containing all the thumbnails. It serves as a DropTarget or drag-and-drop, as a the Scrollable content of the SidePanel, and handles actions when the document is updated, when a popup has run on the selected panels, and when a keypress is received (by way of its InputMap and ActionMap. New actions may be registered with this class by adding ThumbnailPanel.ThumbnailSelectionActions to the viewer. These should respect this objects isEditable() flag if they're going to modify the file.

This class fires "selection" PropertyChangeEvents when the list of selected pages is changed, and "selected" events when the current page is changed.

There's no need to acccess this class unless you're implementing your own ThumbnailPanel.ThumbnailSelectionAction

Since:

2.12
