Re: 4D Write Pro (WP) Area and ST INSERT EXPRESSION

2018-10-09 Thread Pat Bensky via 4D_Tech 
Something like ...

*ST INSERT EXPRESSION*(WriteProArea;"String(Current date;System date long)")


for example.

Re: 4D Write Pro (WP) Area and ST INSERT EXPRESSION

You can use the 4D formula editor with the EDIT FORMULA command.

I don't use 4D Write, but I implemented the formula editor for styled text 
fields (used to implement a markdown editor). 

Editing (by double click) or inserting a formula is something like this:

GET HIGHLIGHT(*;$edName;$start;$end)
Case of 
  : ($start=$end)
  : (ST Get content type(*;$edName)=ST Expression type)  //Formula is selected.
$formula:=ST Get expression(*;$edName)
End case 

If ($formula#"")
  $formula:=UI_Formula_editor ($formula)
  If ($formula#"")
ST INSERT EXPRESSION(*;$edName;$formula;$start;$end)
HIGHLIGHT TEXT(*;$edName;$start;$start+1)
  End if 
End if

4D Write Pro (WP) Area and ST INSERT EXPRESSION

2018-10-09 Thread David Ringsmuth via 4D_Tech 
Insert expression and Get expression seem to not be pre-implemented in the 4D 
v17 Write Pro area.

The documentation indicates this should be managed by the developer, along with 
“Allowed Methods”.

I think the UI for this provide access to allowed tables, fields, methods and 
commands.

If you have already implemented this for a 4D WP area, would you be willing to 
share how you did it?

Thanks!

David Ringsmuth
