How to delete the selected text

[alemrantareq]

Hi everybody, I need a help. I have some contents in a scrolling field and I want to delete the selected from that list. I've tried a lot through delete, clear, put empty commands and also selectedtext, selection, selectedline and selectedchunk functions to do that but failed.

Code: Select all

on mouseUp
  put the selectedtext of fld "asd" into myvar
  delete myvar
end mouseUp

and also -

Code: Select all

on mouseUp
  put the selectedtext of fld "asd" into myvar
  put empty into myvar
end mouseUp

But all have failed. How to do that? Please help...

I tried this with a scrolling field called Field, putting the script in a Button, it worked for me:

Code: Select all

on mouseUp
  delete the selectedText of field "Field"
end mouseUp

try

put empty into the selectedText of field "Field"

Before my posting, I've tried all of these codes. And after your replies, I've tried both of them again renaming my field "asd" to "Field". But failed again. I tried this -

on mouseUp
delete the selectedText of field "Field"
end mouseUp

And got this error -
button "Button": execution error at line 2 (Handler: can't find handler) near "the", char 4

Then I tried this one -

on mouseUp
put empty into the selectedText of field "Field"
end mouseUp

And got this error -
button "Button": execution error at line 2 (Chunk: no target found), char 14

I'm using rev ent. 4. As far as I know, the aboves should work; but I'm afraid why they don't?

Alemantareq,

if you are on windows I think the field looses focus if you click a button. This is not the case on the mac.
To catch this put this into the field

Code: Select all

on focusOut -- for locked text fields
   set the cLastSelection of me to the selectedChunk
end focusOut

on exitfield -- for editable fields
     set the cLastSelection of me to the selectedChunk
end exitfield

this way you make a custom property of the field that gets filled with the last selection. This custom property you can access from your button.
Something like

Code: Select all

on mouseUp
   put the cLastSelection of field 1 into mySelection
   if word 4 of mySelection < word 2 of mySelection then exit mouseUp -- no text selected, just the insertion mark is in the field
   put the number of lines of char 1 to (word 2 of mySelection) of field 1 into tNumOfLines -- find out how many lines up to the begin of the selection
   delete line tNumOfLines of field 1
end mouseUp

If this is the problem then I can not really test it because I dont have access to a windows computer. You might want to experiment with this a bit.

Bernd

Yes, I'm using windows xp and its the text locked field. Thanks Bernd for your reply but it doesn't work for me. Oh ! its really making me disappointed.

Here just do it like this

Code: Select all

put empty into the selectedText

and it should work. I always forget that selectedText is its own container.

edit: at least this works on my win2k, don't have other test beds available.

Thanks a lot sturgis; your correction really works

[alemrantareq]

Putting empty into the selectedText deletes the text but that line turns to an empty line and still exists. Is there any way to delete that empty line?

[sturgis]

My apologies, I thought you were trying to delete part of a line that had been selected IE removing a portion of the text. If you just want to remove all hilited lines in a list field you can do this.

Code: Select all

on mouseUp
   repeat for each item tLine in the hilitedLines of field "Field"
      delete line tLine of field "Field"
   end repeat
end mouseUp

[alemrantareq]

Using repeat loop was in my mind but I didn't try it thinking that it'd not work as the selectedLine, selectedText of fld "Field" had failed.

However, Thanks a lot (u r great )

A slight variation may be required if you are deleting multiple lines, as when you delete the first line in the list, then every other line below it will be shuffled up one line, and the next delete will be offset by a line, and that can compound over the repeat loop too. If you sort the hilitedLines list first, so that you delete the highest line number then the next highest, etc, each line number in the list will still match the original selection:

Code: Select all

on mouseUp
   put the hilitedLines of field "Field" into tLines
   sort tLines descending
   repeat for each item tLine in tLines
      delete line tLine of field "Field"
   end repeat
end mouseUp

When applying this excellent tip in LC 9 I had to specify that the items were the subject of the sort e.g.

Code: Select all

put the hilitedLines of field "FullList" into tLines
   sort items of tLines descending
   repeat for each item tLine in tLines
      delete line tLine of field "FullList"
   end repeat

Hi,

Is there any way to delete that empty line?

Code: Select all

filter fld "myField" without empty

works (LC 9, OS X 10.13)
