[SOLVED] Weird behaviour adding jListview item with brackets

Hi there!

I've just found a extrange behaviour when adding an item to a
jListview which contains brackets. You can reproduce it using, for
instance, the AppDemo1 inside Listview Module.

If you add an item with the text 'hello(there' the component only
displays 'there'
If you add an item with the text 'hello)there' it only displays hello
If you add an item with the text 'hello(t)here' the output is 't'
(and, to my astonishment, flipping the positions of the image and the
checkbox controls inside the item!!!)

Is it a bug or a hidden (to me) feature?

Hi, jluixjurado!


"("   and  ")"   are defaults left/right  item text
delimiter/separator ....


example:

'Hello(Android)World'    will produce:


Hello                   Android               World

Hi, jmpessoa! Thanks for your answer.

I didn't know about those left/right delimiter properties (and I can't
find them in the jListView Object Inspector Window) and, what most
struck me was the change of position between the row image and the
control when using both ( and ). I would like to disable the default
parenthesis behaviour, but I can't sort out how.

BTW: Have been you able to read my last post in this topic
(https://forum.lazarus.freepascal.org/index.php/topic,60560.0.html)? I
think there could be a problem with the new INSERT method you added to
jListview a week ago. If you don't have time to fix it I would like to
help but I need a bit of advice because I'm not sure how things behave
in LAMW (altough I have some experience in Pascal and Android Java)

Thanks again!

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.AndroidModule1JNIPrompt(Sender: TObject);begin 
 jListView1.SetLeftDelimiter('['); 
 jListView1.SetRightDelimiter(']');end;

Good!

You are welcome!

I can help you about how LAMW code works!

Oh!

I hadn't noticed those methods!

Thank you very much!
