Class PrintPreviewTray

java.lang.Object
org.eclipse.jface.dialogs.DialogTray
de.cau.cs.kieler.klighd.ui.printing.dialog.PrintPreviewTray
public class PrintPreviewTray extends org.eclipse.jface.dialogs.DialogTray
A PrintPreview to be displayed as a dialog tray, e.g. used by KlighdPrintDialog.

The implementation is inspired by org.eclipse.gmf.runtime.diagram.ui.printing.internal.printpreview.PrintPreviewHelper of the GMF project, esp. PrintPreviewHelper.updateCompositeForNumberOfColumns(int, int).

Note: There's no method 'dispose()' or similar, since all required dispose routines are coupled to the disposal of the employed SWT widgets. Their disposal is invoked by TrayDialog#closeTray(), which is inherited by our KlighdPrintDialog.
