ecflow standalone GUIs
Axel Bonet posted on Jan 22, 2014
Among reasons to use ecFlow is certainly its simplicity with simple Python clients.
Tkinter, as the graphical interface available with Python, may be used then, to customize simple GUIs.
Some time may be dedicated learning the basics (Tkinter)
Application skeleton starts with:
from Tkinter import * root = Tk() w = Label(root, text="Hello, world!") w.pack() root.mainloop()
There may be the remembering of the 'overview' interface: it displays current tasks in submitted, active and aborted states from a server.
To do so with ecFlow, Python and Tkinter, we may use a ScrolledList widget to list such tasks.
It is trivial to add an update button so that user can request most recent content.
A dedicated class is also created to cause regular refresh (PaceKeeper)
Queue module shall then be used to deal with the asynchronous aspect.

It is not really far ahead to provide a treeview display of the server content, using ttk.Treeview widget.
ecFlow is "destination agnostic": it just submits local commands that can lead to remote jobs submission. The Treeview interface may bridge the ecFlow tree understanding of the current situation with the system side. It can display the target node (HPC, linux_cluster, localhost, workstation), the id of the active job, or the identification of the submitted job (qid). Check command is then expected to validate and match the server information with the query from the queuing systems, or remote machine.
A contextual menu is added to display task manual, script, job, or output, when available.
