Persistent variables - save/restore variable value on restar

[TRIROG1]

Hi!

Is it possible to somehow save the value of a certain variable so that when i restart the EG, the state of variable is not lost?

e.g. if i assign a eg.globals.myVar = 1 and then restart the EG, the myVar variable no longer exists. What should i do to save that variable?
Is writing it to a file an only way?

Thanks!

Here are two of the ways to solve it:

• Check the file FindWindow.py (it's part of the plugin Window).
  There search for the keyword "eg.PersistentData" and see how it treats the variable "hideOnDrag".
• You can use the Webserver plugin or Tornado plugin (which actually no, if you do not like it)
  and actions "Set persistent value" and "Get persistent value".
  It is not necessary to use these your variables as well as inside Webserver/Tornado plugin.

I've done it like this:

eveything on the Auto Start (i have it in spanish, i don't know exactly the words so i'll try to explain myself).

1- Python Script:

Code: Select all

eg.globals.Dashboard_X1 = "0"

with each variable. IT CREATS THE VARIABLE.
2- Create a Folder and in it one file.txt for each variable. SOMETHING THAT IT'S NEEDED FOR THE NEXT STEP.
3- Python Program

Code: Select all

f0 = open("C:\...................\EG_variables-DASHBOARD_A1.txt","r")
data = f0.readlines(0)
eg.globals.Dashboard_A1 = data[0]
f0.close()

f1 = open("C:\...........\EG_variables-DASHBOARD_A2.txt","r")
data = f1.readlines(0)
eg.globals.Dashboard_A2 = data[0]
f1.close()

and so on.
IT READS THE 1ST LINE OF THE SPECIFIC FILE AND TURNS WHAT IT'S WRITTEN ON IT IN TO THE VARIABLE.

TO WRITE THE VARIABLE ON THE FILE Not in start up

Code: Select all

w = open("C:\.......................\EG_variables-DASHBOARD_B4.txt","r+")
w.write("THE VARIABLE")
w.close()

Hope it helped

Great!
Juanson:
thanks for this tip regarding the save to file method.

Pako:
I looked at the hideOnDrag, but unfortunately it doen't tell me much.

Would you be so kind and help me with an example please?

Btw:How can i remove/delete a persistent variable from the tornado?

Kind regards to all!

There you can see everything what is needed.
Maybe you are missing some python skills. This is not the appropriate place to address this problem.
