Extend the run file widget and use in the SANS GUI

[Steve Williams]

The run file widget must be able to optionally deal with multi-entry workspaces. If "-add" is added to the end of a run number this must be added to the end of the filename to load.

The SANS GUI will then beable to accept file names as well as run numbers. There will be an option for multi-period entry boxes.

[Steve Williams]

(In [9075]) The run files widget now has optional workspace entry selection boxes. It now checks if a non-run files exists and looks for files less frequently to lock the GUI less re #2337

(In [9084]) File widget improvements re #2337

[Nick Draper]

Bulk move of tickets at the end of iteration 27

[Steve Williams]

(In [9810]) File widget has new options to have a small browse for file icon instead of a button or neither one re #2337

[Steve Williams]

(In [9974]) Run numbers entered into a RunFile widget ending in "-add" will cause a file whose name ends in -add to be loaded. Fix system tests re #2612 and #2337

Steve, just a suggestion/comment.

At the moment we (as in the US) are in the position where all our files have custom suffixes. Up until now, we are just specifying them as part of the extension so the File Finder can locate them. It is probably better to handle them separately as you have, but wouldn't the list of allowed extensions be facility or even beamline specific? Might it be a good idea to have these extensions listed in the facilities XML file?

[Steve Williams]

Stuart's suggestion has moved into ticket #2674

[Michael Whitty]

when entering a run number with "-add", such as "54431-add" into the Sample box, I get the following error:

Sorry, MantidPlot has caught an unexpected exception:

bad lexical cast: source type value could not be interpreted as target

Would you like to terminate MantidPlot or try to continue working?
If you choose to continue it is advisable to save your data and restart the application.

It does give lots of nasty error messages if you facility is not set to ISIS before you launch the GUI.

Added some files together to produce a "-add" file. then reduced this. Seems to be ok.
