[Xerte] How do you detect someone clicking on text that has beenmarked with the hot text tags?

[Julian Tenney]

Good question.

I don't know. What I would try first of all is getting an event handling
myTextIcon.txt.onSetFocus. Then try using the Selection.getCaretIndex()
to get the position of the caret in the text, and figure things out from
there. You need to turn on selectableText on the LO icon to allow the
text field to have the caret placed into it. I've got it this far... see
attached.

Problem I get is Selection.getFocus() returns null, so might need a
short delay before looking for Selection.getBeginIndex(), and then using
substr / indexOf to find out where you are in the string.

There might be other approaches.

Subject: [Xerte] How do you detect someone clicking on text that has

Dear Xerte Team,

I have a text icon which contains text that is to long to fit in the
text box, so I am using a scroll bar. However I want to trap the user
clicking on sections of the text.

If I use a hot spot this becomes out of position when the user scrolls
the text icon, as the text moves but the hot spot does not.

Could I use the hot text tags to mark the text I want the user to click
on?

If so how would I then trap the event, distinguishing between one
section of text within the icon and another?

I am trying to avoid breakApart() as the text icon in question is being
used as a display area, being populated by script that reads the text
property of the appropriate text icon to be displayed and then using
setText() to set the text of the display text icon. If I can just put
tags in the text that would be ideal.

Kind regards

Johnathan
