[Kst] Apply df1.kst for df1.dat to df2.dat from kst2 GUI

Sun Apr 19 19:36:09 UTC 2015

Hi Roger,

I'm not sure I understand what you want to do. Basically, changing the .kst files from an editor is not recommended, even though under most circumstances it will work. But it's not easier and it is less safe than using the Change Data File tool.

A few more hints:
- the .kst file does not store the data file, only pointers to it - as you have seen
- when data file changes, you can hit the "reload all data sources" button to force kst to re-read the data
- it would be feasible to teach the ASCII data source to re-read the data if the data file shrinks or gets a newer write date. It has already been discussed. One issue could be remote file systems or network mounts, where buffering and latency may break the detection though
- you have a -F switch for the command line which allows forcing the data file to something else. I.e. if the .kst file points to df1.dat you can call kst like this: "kst2 -F df2.dat" and it will read data from df2.dat instead of df1.dat
- your issue below seems to come from the fact that you have Qt installed for various applications, one of them being Kst. Apparently the OS gets confused, but it's not a Kst issue

Best regards,

Nicolas
