Hover detection with listview .. is it posiible

6 posts in this topic

I would really like to detect when the mouse is hovering over a listview item. I have managed to get single and double click events to work but have failed to get the hover function running.

Here is my code

CODE
#include <GUIConstants.au3>

; Global constants for mousclick detection & ListView Events

Global Const $WM_NOTIFY = 0x004E

Global Const $NM_FIRST = 0

Global Const $NM_LAST = (-99)

Global Const $NM_OUTOFMEMORY = ($NM_FIRST - 1)

Global Const $NM_CLICK = ($NM_FIRST - 2)

Global Const $NM_DBLCLK = ($NM_FIRST - 3)

; Global Const $NM_RETURN = ($NM_FIRST - 4)

Global Const $NM_RCLICK = ($NM_FIRST - 5)

; Global Const $NM_RDBLCLK = ($NM_FIRST - 6)

; Global Const $NM_SETFOCUS = ($NM_FIRST - 7)

; Global Const $NM_KILLFOCUS = ($NM_FIRST - 8)

; Global Const $NM_CUSTOMDRAW = ($NM_FIRST - 12)

Global Const $NM_HOVER = ($NM_FIRST - 13)

; Global Const $NM_NCHITTEST = ($NM_FIRST - 14)

; Global Const $NM_KEYDOWN = ($NM_FIRST - 15)

; Global Const $NM_RELEASEDCAPTURE = ($NM_FIRST - 16)

; Global Const $NM_SETCURSOR = ($NM_FIRST - 17)

; Global Const $NM_CHAR = ($NM_FIRST - 18)

; Global Const $NM_TOOLTIPSCREATED = ($NM_FIRST - 19)

Global Const $LVN_FIRST = -100

Global Const $LVN_BEGINDRAG = ($LVN_FIRST - 9)

Global Const $LVN_ENDDRAG = ($LVN_FIRST - 21)

;endregion End Global variables

GUIRegisterMsg($WM_NOTIFY, "_WM_Notify_Events")

GUICreate("listview items",220,250, 100,200,-1)

$listview = GuiCtrlCreateListView ("col1|col2|col3 ",10,10,200,150);,$LVS_SORTDESCENDING)

$item1=GuiCtrlCreateListViewItem("Data|Data|Data",$listview)

$item2=GuiCtrlCreateListViewItem("Data|Data|Data",$listview)

$item3=GuiCtrlCreateListViewItem("Data|Data|Data",$listview)

$label = GUICtrlCreateLabel("Single,double or right Click any row", 10,210,230,20)

GuiSetState()

Do

$msg = GuiGetMsg ()

Until $msg = $GUI_EVENT_CLOSE

;----------------------------------------------------------------------------------------------

Func _WM_Notify_Events($hWndGUI, $MsgID, $wParam, $lParam)

;----------------------------------------------------------------------------------------------

#forceref $hWndGUI, $MsgID, $wParam

Local $tagNMHDR, $event, $hwndFrom, $code

$tagNMHDR = DllStructCreate("int;int;int", $lParam);NMHDR (hwndFrom, idFrom, code)

If @error Then Return

$event = DllStructGetData($tagNMHDR, 3)

if $wParam = $ListView then

;ConsoleWrite($Event&@crlf)

If $event = $NM_CLICK then GUICtrlSetData($label,"Single Click detected") ; Works

If $event = $NM_DBLCLK then GUICtrlSetData($label,"Double Click detected") ; Works

If $event = $NM_RCLICK then GUICtrlSetData($label,"Right Click detected") ; Works

If $event = $NM_HOVER then GUICtrlSetData($label,"Hover detected") ; Doesn't Work

EndIf

$tagNMHDR = 0

$event = 0

$lParam = 0

EndFunc ;_WM_Notify_Events

Any help would be greatly appreciated

:whistle:

Is there any way to make it so that the row is not selected when the hover occurs ?

I have tried using $LVS_EX_INFOTIP instaed of $LVS_EX_TRACKSELECT but can't get it to work
