需要实现:当窗口出现后自动选中索引项目第3项，当选择其它项目时取消索引项目的第3项，在线求助。

; 在窗口创建后默认选中索引3
_guictrllistview_setitemstate($hlistview, 3, $lvis_selected, $lvis_selected)

使用此项选中索引3后，当窗口出现鼠标悬停到选择的索引3条目时，文字会丢失不全，重新点击才正常显示

感谢回复，但是还是没达到要求，当点击了列表以外按钮焦点高亮消失，而原先的是不会失去高亮显示的
使用_guictrllistview_setitemdrophilited($clistview, 3, true) 此项可以保持高亮，现在有个问题就是，当点击其它项目后怎么取消已经选中的高亮项目3

代码如下

$gui = guicreate("listview custom draw", 400, 300)

$clistview = guictrlcreatelistview("column 1|column 2|column 3", 2, 2, 394, 150, -1, bitor($lvs_ex_gridlines, $lvs_ex_fullrowselect))
$hlistview = guictrlgethandle($clistview)

for $i = 1 to 30
      guictrlcreatelistviewitem("row" & $i & ": col 1|row" & $i & ": col 2|row" & $i & ": col 3", $clistview)
next
;~ guictrlcreateinput("click here to test focus", 50, 275, 200, 18)

;设置选中项目高亮显示
_guictrllistview_setitemdrophilited($clistview, 3, true)

$button1 = guictrlcreatebutton("测试按钮", 100, 154, 60, 27)
guiregistermsg($wm_notify, "wm_notify")
guisetstate()

do
until guigetmsg() = $gui_event_close

exit

需要实现以上第二张图片要求，点击按钮或者窗口外其它项目，列表框内选中的条目高亮不会消失
