I have to say it's annoying. What's even more annoying is that most of the time CALL FORM isn't enough. You have to use SET TIMER(-1) and set some info somewhere to let the timer know what to do when it triggers. I don't find it anwhere near as simple or intuitive as working with 4D Write was. I live in hope that things will become easier to manage as the product improves. Certainly there are steps forward with each new release. ** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
RE: Write Pro: programmatically manipulate text expertise needed
Hi Justin, Pat,
Using WP SELECT that is called in a method via CALL FORM seems to work, thanks
for that!
I must say, I can't believe it's 4D's intention that we constantly have to use
CALL FORM for thinks to work.
Maybe they implement a more sophisticated way for doing this.
Thanks again,
Piotr

WP SELECT is the way to go but, like many things in 4D Write Pro, you need to
do it in a separate execution cycle (from the ST SET TEXT).
CALL FORM will work in this instance (it doesn't work in most of the instances
where 4D Write Pro needs to complete the current execution cycle before any new
changes can be applied).
So, have a separate method to which you pass your 4D Write Pro object and your
$endpos and run the WP SELECT from there. Call the method after your ST SET
TEXT using CALL FORM.

Re: Write Pro: programmatically manipulate text expertise needed
Hi Piotr,
I think you can use WP SELECT to do this -
WP SELECT ( {* ;} wpArea {; targetObj} | {; startRange ; endRange} )
Let me know if you can't get that to work and I'll take a closer look at it.

Re: Write Pro: programmatically manipulate text expertise needed
Piotr, 1. I think you will need to use ST GET PLAIN TEXT to get all the text after the specified range and then look for the first return character in that selection. I believe this is the only way to get an accurate position with styled text. 2. Again, use ST GET PLAIN TEXT to get a range of text from the cursor position back n characters or to the beginning of the text.
