Status / progress indicator

A simple progress bar indicating the current status, the elapsed time and the remaining time.

Description

Statusbar is a simple GUI to display the progress of a lengthy computation. It displays the current state and the elapsed time as well as the estimated time to finish.

On confirmation, the user can interrupt the computation by closing the window. At every update, the application program is signaled if it should stop or continue.

Statusbar minimizes processor load by updating only if either the elapsed time or the progress changed (i.e. at most once per second or 0.4% advance).

Excellent

It's really good if you should run on values of a known vector in loop

Very Nice Job!

Works fine but occasionally, when hitting the Continue button, it throws the following exception:

I'm using Matlab v7.0.0 R14

Very nice. But as in the original waitbar if I switch to another window and then back to the statusbar window I don't see any content until the next update of statusbar in my programcode. In lengthy calculations this might take some time.

A great tool! I don't like how the close request function is set up to keep you from being able to close the status indicator though. Sometimes I interrupt my simulation and start it over again, and the old, defunct status bar won't go away automatically, so to get around not being able to close it i have to use delete(statusbar). But overall, great job!

[John Henkel]

Beautiful. Drop it in, and it works. Great job!

Well It would be Nice to show how to use the status bar, than just watching it
