That is why I did not really= want to use a queue. That is because if a bunch of the thread that create = the images finish really close to one another (when they should be spread o= ut based on how the music is played), then there would be a larger "lag" in= the display. So displaying only the most recent image is preferred.=20 That is why I though Stack...but then that might mean that older images wil= l replace newer ones. The Workflow is as such: 1) Music is analyzed and streamed to the program. Note-by-Note. 2) The note is grabbed (same way as a Java Scanner class) 3) A new thread is created to call an OS command (Lilypond command) a) Thread waits until command is finished, and Lilypond creates an image= that I can define the filename for in a directory. >From here I want only the latest one (as close to the latest one at least) = to be displayed to the gtkImage object in the GUI I set up a class that would act as a directory monitor (just stubbed)...tha= t would do all the work I am asking for here Also, don't think this matters much, but I am using Windows (I seen someone= mention Linux)
