Dear Antonio,
this is looking very professional. Thank you.
I tested the code and the treeview is not only good looking but very speedy too.
Best regards,
Otto

Dear Antonio,
I get following error:
Error description: Error BASE/1004 Class: 'NIL' has no exported method: EVAL
Args:

Thank you in advance

Dear Otto,

But I do not understand why if this modification is in the repository, it is not included in the published version. Antonio?

Now you have

Code: Select all  Expand view

 
      Eval( bInit, oEditor1 )
 
 

Please put this code at end of Function SetupScint, and try

Code: Select all  Expand view

   if bInit != nil .and. Valtype( bInit ) == "B"
      Eval( bInit, oEditor1 )
   endif

 

[Carles]

Hi,

Code: Select all  Expand view

  if Valtype( bInit ) == "B"
     Eval( bInit, oEditor1 )
  endif

[cnavarro]

Carles, thanks

[cnavarro]

Better, replace this function
