Is there a way to set the jListView to a specific item that is
viewable, you can set it to an index but does not reflect visibly. The
jGridView component has .setSelection which works fine, but nothing
for jListView? is their a workaround for this?

Really appreciate the work done on LAMW btw

Hello, c4p!

Please,  update LAMW from github and try:

 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.jButton1Click(Sender: TObject);begin 
 jListView1.HighLightSelectedItemColor:= colbrRed;  //any color <>
default!   jListView1.SetItemChecked(5, True);  //some  valid index
.... 
 ShowMessage(IntToStr(jListView1.GetCheckedItemPosition()));end; 
Note: I will try some improvement to scroll to selected index...

Thank you!

This works, if I could get it to autoscroll to the position, that
would be great.
