Examples of java.awt.MediaTracker.waitForID()

java.awt.MediaTracker.waitForID()
Starts loading all images tracked by this media tracker with the specified identifier. This method waits until all the images with the specified identifier have finished loading.
If there is an error while loading or scaling an image, then that image is considered to have finished loading. Use the isErrorAny and isErrorID methods to check for errors. @param id the identifier of the images to check @see java.awt.MediaTracker#waitForAll @see java.awt.MediaTracker#isErrorAny() @see java.awt.MediaTracker#isErrorID(int) @exception InterruptedException if any thread hasinterrupted this thread.
