Class PreviewWrapper.PreviewWrapperInitializer

java.lang.Object

java.lang.Thread

org.wandora.application.gui.previews.PreviewWrapper.PreviewWrapperInitializer

All Implemented Interfaces:

java.lang.Runnable

Enclosing class:

PreviewWrapper

protected class PreviewWrapper.PreviewWrapperInitializer
extends java.lang.Thread

------------------------------------------------------------------------ PreviewWrapperInitializer is a Thread that solves the preview viewer class, instantiates preview viewer and initialized it. Downloading and initializing the preview in a thread of it's own, Wandora's user interface doesn't block and freeze if it takes longer. Notice, the thread exits once the preview is ready. If the user stops (exits) the preview for some reason, the isAborted variable is set true and the thread does as little as it can. The thread is never really killed (forced to abort) though. This is because the preview may become unstable if the initialization is stopped carelessly.
