Ich möchte gern per GUIRegisterMsg die Änderung der Spaltenbreite eines Listviews erkennen. Ich finde aber keinen Notifywert, der das repräsentieren würde.
Aber mal der Reihe nach:
Ich habe das bisher so (naja, quick and dirty, aber funktioniert) gemacht:
Spoiler anzeigen
#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
Opt('GUIOnEventMode', 1)
$hGui = GUICreate('Test', 600, 400)
GUISetOnEvent($GUI_EVENT_CLOSE, '_End')
GUISetOnEvent($GUI_EVENT_PRIMARYUP, '_GetColWidth')
$hListView = GUICtrlCreateListView('A|B|C', 10, 10, 580, 200)
GUISetState()
$hLabel = GUICtrlCreateLabel('', 10, 230, 580, 100)
While Sleep(500)
WEnd
Func _End()
Exit
EndFunc ;==>_End
Func _GetColWidth()
Local $sColWidth = ''
For $i = 0 To 2
$sColWidth &= _GUICtrlListView_GetColumnWidth($hListView, $i) & @CR
Next
GUICtrlSetData($hLabel, $sColWidth)
Return $GUI_RUNDEFMSG
EndFunc
Ich hätte das aber lieber per WM_NOTIFY (oder gibt es da noch eine andere Möglichkeit?):

Hier bekomme ich aber keine Ausgabe von _DebugPrint, wenn ich die Spaltenbreite verändere. Eigentlich ja auch klar, da der iCode ja nicht dabei ist. Aber wie lautet der richtige Code?
Ich habe auch schon auf MSDN nachgesehen, aber nichts brauchbares gefunden.
Jemand eine Idee?
