can't click in listview area

[webber]

Trying to build an autocomplete script but finding that I can't click inside the listview box to select an item.

What am I missing ?

Thanks that helps some.

Unfortunately when I enter a value like "b" it selects the b_item and then when I click on the listview the value changes back to a_item

I don't understand how this listview is supposed to work.

is this a bug in Listview ?

[GaryFrost]

No bug, you have to tell it you want to be able to edit i.e. $LVS_EDITLABELS

I changed listview line to be :

$listView = GuiCtrlCreateListView("key|text",10, 45, 175,190,$LVS_EDITLABELS)

but it still behaves as before, and there seems to be no way to capture listview selection .

Each try tells me $listview has not been declared, but if I declare it then the click in listview doesn't work.

Isn't there someway to have a dynamic listview where the value can be clicked for selection and retrieved for use ?

I think it has something to do with the fact that you're recreating the listview everytime you call GetList. Create it in the beginning and use GetList to update it using GuiCtrlSetData.

Also, use something like this in your Do loop:

Do
    $msg = GUIGetMsg ()
    If $msg = $Input Then
        $testvalue = GUICtrlRead ($Input)
        if $testvalue <> $oldvalue then GetList($testvalue)
        $oldvalue = $testvalue
    EndIf
;MsgBox(0,"listview", "clicked="& GUICtrlGetState($listview),2)
Until $msg = $GUI_EVENT_CLOSE

my fault, commented out the wrong create.

did you try your suggestion? I think things are getting worse ?

[GaryFrost]

looks like $LVS_EDITLABELS doesn't work, it goes into edit mode but doesn't save what is typed.

DOA ............

No I didn't, but I'm pretty sure it would be more efficient and use less CPU to test for something happening in the input box before reading from it instead of just constantly reading from it.

All I did was add the "if" and have it check the new value against the old value. There's no need to do anything if the text hasn't changed. Clicking in the input box would trigger an $input event, but not change the value of it.
