Kill Drag Ability From Listview

duketrapp · April 14, 2006

Hi again...

I have a small prob with a listview item.. cant find any threads about that...maybe u can help me out..

prob is:

i have a listview filled with some listviewitems.. when the user select an item of the listview, different other controls get there specific settings.. = works great

..BUT.. when u click on an item in listview, than hold the mousebutton down and move the mouse in any direction (curser change to drag/drop icon) over the listview and release the selected item, the other controls DONT get there settings!!!..

i thnk the prob is that the listview dont send the id from the click on the listviewitem, when u click,drag and release the listviewitem... the listview thnks its an drag/drop action and dont notice the click...

..so i thinked about it and best possible choice for me is to completely DISABLE the DRAG ABILITY of the listview.. how can i do that???... i found some comands that set the ability to accept droped files but no comands for disable the ability of a control to be "draggable"... :think:

.. i hope u understand my prob.. maybe u know a hint...

thnks for help..

salute..

from styles

WS_EX_ACCEPTFILES 0x00000010 Allow an edit or input control within the created GUI window to receive filenames via drag and drop. The control must have also the $GUI_DROPACCEPTED state set by GUICtrlSetState.

make sure that this "WS_EX_ACCEPTFILES" is NOT in the create line

hey man.. ive seen that in docu but it says "Allow an edit or input control within the created GUI window to >>>!!!!"""RECEIVE"""!!!!<<< filenames".. Thats not my prob.....i want to kill the ability to GRAB an item out of the list....

check this out...

#include <GUIConstants.au3>

GUICreate("check", 300, 300, 1, 1)
    GUICtrlSetState( -1, $GUI_SHOW)
        
        $check_list = GUICtrlCreateListView("col1|col2|col3", 5, 5, 290, 150, $LVS_SHOWSELALWAYS+$LVS_SINGLESEL)
        $1 = GUICtrlCreateListViewItem ( "text1|text1|text1", $check_list )
        $2 = GUICtrlCreateListViewItem ( "text2|text2|text2", $check_list )
        
        $getit = GUICtrlCreateLabel("test", 5, 200, 290, 20)

GUISetState ()

Do
  $msg = GuiGetMsg ()
  
    Select
        Case $msg = $1
            GUICtrlSetData($getit, GUICtrlRead($1))
        Case $msg = $2
            GUICtrlSetData($getit, GUICtrlRead($2))
    EndSelect
     
Until $msg = $GUI_EVENT_CLOSE

..u see i try to create without "WS_EX_ACCEPTFILES" and it still not workin.... click on "text1" listviewitem, DONT release the mousebutton and pull the item under the list... label text will not change... voila... still shit..

.. other ideas?..

.. .. i thnk its a lot of goodlookin stuff over there but can u give ur hint a bit more transparency.. :think: .. im still learnin autoit.. so... beta is ok.. im usin it... and the code u posted... when i look at it i thnk my problem should be killed here :

Select
                    Case $event = $LVN_BEGINDRAG
                        ConsoleWrite("Drag Event:" & @LF)
                        ConsoleWrite("Item: " & _GUICtrlListViewGetItemText ($ListView, DllStructGetData($tagNMLISTVIEW,4)) & @LF)
                EndSelect

..but... ..i realy dont know what to do with this.. :"> .. so maybe u can give me a small advise...

..btw .. i thought this would be easy.. but.. when its that kínda difficult to kill the ability i thnk i can survive with this small bug in my script.. cause i dont want start and change anythng in the autoit standards or includes if this affects any other control devices... maybe i need drag and drop ability later in an listview...

I don't know how to kill the ability, maybe Holger does, but you said the info wasn't filling in when the user clicked and dragged, I was showing you that you could get the info, then it would be up to you to use that info to fill in what needs to be done.

y..... i knowed that u say somethng like that... .. i can do a lot with the autoit comands and scite till now... but this code above looks like chinese for me..

..but thnks a lot for ur hint... maybe ill find a way when im deeper in autoit :think:

Sorry it looks chinese for you, but you didn't provide any code to adapt it to.

debug or not to debug, just for testing, if you take it out, make sure you remove all references to it.
