Re: Field highlited
The effective attribute is what I was looking for. As Paul mentioned, if you just say “set the background of… to hiliteColor” you don’t get anything. But if you set it to the “effective hiliteColor” you get the system default (btw, I tried “system hiliteColor” but LC treats it as a syntax error. Pity, since “system” in this case makes more sense to me than effective. But that’s another story…) I was intrigued by Pauls example of trying to set some highlighting that “sticks” but that still gives the user the illusion that nothing unusual is going on ie. If you select another portion of text, the first selection unhighlights, of if you click in the field the highlighting goes away, but you can click in other fields and it doesn’t. I saw it as a challenge to try and get that working. He probably has more elegant code than I do but the following comes very close, I hope, to the solution he was describing. The biggest challenge I found is that when you have a selection in the field, and you go to change it to some other text the normal behaviour is to have the first selection immediately disappear. That doesn’t happen if you are depending on a selectionChanged message since you don’t actually get that until the end of the 2nd selection and you need the old one to disappear when you start the 2nd selection. I solved that by having an openField handler that just checks to see if there is a selection, and if there is, removes it. openField happens immediately and before selectionChanged is sent. I can’t remember at the moment why I left the removal in both handlers, but it seems it was necessary for some combination of clicks or selections. I’d have to go back and test that again. on openField -- a selection is potentially about to begin -- see if there is already a selection in the field and unhighlight it put the cpChunkExpression of field "fld1" into chunkExp if chunkExp is not empty then set the backgroundcolor of chunkExp to "" -- gets rid of our fake highlighting set the cpChunkExpression of field "fld1" to empty end if end openField on selectionChanged -- get the current highlight color put the effective hiliteColor of field "fld1" into tHiliteColor -- then initialize our new chunk expression put the selectedChunk of fld "fld1" into newChunkExp -- determine if there is an old chunk we need to unhighlight put the cpChunkExpression of field "fld1" into chunkExp if chunkExp is not empty then set the backgroundcolor of chunkExp to "" -- gets rid of our fake highlighting set the cpChunkExpression of field "fld1" to empty end if -- now, with regards to the new chunk expression there are 3 possibilities -- 1. its empty, in which case we do nothing -- 2. its just an insertion point, in which case we do nothing (ie. word 2 of newChunkExp > word 4) -- 3. But, if word 2 and word 4 of newChunkExp define a range of text, highlight it if word 2 of newChunkExp < word 4 of newChunkExp then set the backgroundcolor of newChunkExp to tHiliteColor -- and save it for future reference set the cpChunkExpression of field "fld1" to newChunkExp end if -- if we want to unhighlight everything we can just click anywhere in the field end selectionChanged > On 14 Jul 2023, at 9:39 pm, J.

Re: Field highlited
Use the effective keyword as in: put the effective hiliteColor of field X into tHiliteColor It will figure out the color by inheritance.

Re: Field highlited
Hi Paul, try “the selectedText". Create a scrolling text field, call it fld1, and put a large amount of text in it. Create 2 buttons: one with “on mouse down, answer “Hello World” and the other with “on mouse down, answer the selectedText of field “fld1” Now highlight an area of text in fld1. Click either button, the highlight in the text does not go away. The first button responds with “Hello World” and the second responds with the highlighted text in fld1. I am using LC 10 if that makes a difference, although just tested in 9.6.8 and it worked there as well.

Re: Field highlited
Paul. I think that Bob S. is correct. The change in focus is sort of built into the engine, and a field cannot “remember” such a thing. A fun kludge would be to create one or more overlays, however you like those to look, and apply them to the field of interest. These overlays can be managed in terms of their rects, depending on the formatted properties of the hilted line or lines. They can be shown and hidden as well. I am struggling not to do this just for fun. So you do it, because I bet that the team has bigger fish to fry.

Re: Field highlited
I do not see how that could work. In Windows, buttons can have the focus, which means a field would always lose it. What I do when I need something like this is I save the selection (or selectedChunk or some such thing) as a property of the field upon exitField. You could even put that in a frontScript and reference the target. Then in the field script re-select the text upon enterField.
