SynEdit empty

[BubikolRamios]

1. create
Lines.count = 0;
text = '';
ALL OK

2. Put some text in it, delete all
Lines count = 1 // appears that is logical
text <> ''// as it seems as if sentence does not see empty SynAdit as ''

How to tell there is nothing in SynEdit ?

[Martin_fr]

SynEdit does currently not store line endings.
But, if you retrieve the text, it will add a line ending to each line. So if Lines.Count=1 (with one empty line) then you get a line-ending back in the Text.

As for the "how to test", good question.
Maybe
   (Lines.Count=0) or ( (Lines.Count=1) and (Lines[0]='') )
Not great, but...

If you don't care for spaces (which as synedit has arbitrary cursor positions you probably won't), this is the easiest:

Code: Pascal  [Select][+][-]

1. SynEdit1.Text.Trim.IsEmpty
