using the __wm_notify function

2 posts in this topic

I admit that I do not understand the _wm_notify function. I created a treeview menu for server documentation:

+Server1

+backup

-filename

+baseline

-filename

+configuration

-filename

+Server2

+backup

-filename

+baseline

-filename

+configuration

-filename

+Server3

+backup

-filename

+baseline

-filename

+configuration

-filename

I only want the function to respond to a double click on the filenames. Any help would be greatly appreciated. Thank You.

Local $tNMHDR, $hWndFrom, $iCode

$tNMHDR = DllStructCreate($tagNMHDR, $lParam); creates a c/c++ style structure, structure is $tagNMHDR, $1Param is the pointer

$hWndFrom = DllStructGetData($tNMHDR, "hWndFrom");$tNMHDR is the structure created.

$iCode = DllStructGetData($tNMHDR, "Code"); get returned data

Switch $hWndFrom

Switch $iCode

Case $NM_CLICK ; The user has clicked the left mouse button within the control

Local $tPOINT = DllStructCreate("int X;int Y")

DllStructSetData($tPOINT, "X", MouseGetPos(0))

DllStructSetData($tPOINT, "Y", MouseGetPos(1))

_ScreenToClient($hTreeView, $tPOINT)

Local $iX = DllStructGetData($tPOINT, "X")

Local $iY = DllStructGetData($tPOINT, "Y")

Local $iItem = _GUICtrlTreeView_HitTestItem($hTreeView, $iX, $iY)

If $iItem <> 0 Then

$vSelected = _GUICtrlTreeView_GetText($hTreeView, $iItem) & ".pdf"

ToolTip($vSelected, 0, 0)

EndIf

EndSwitch

EndSwitch

Return $GUI_RUNDEFMSG

Return $aRet[0]

EndFunc ;==>_ScreenToClient

If you only want double-clicks, why select for $iCode = $NM_CLICK instead of $NM_DBLCLK?

After that, you have to see which item was clicked on, then determine if it was a "filename" type or not. The TreeView control doesn't know the difference, so you'll have to figure that out for yourself.

On receiving WM_NOTIFY from the TreeView's Hwnd, and with a Code of NM_DBLCLK, you want to get the handle of the selected item and see if that item is in you list of "filenames" or not.
