Why doesnt GUICtrlCreateListView sho scrollbar?

4 posts in this topic

Why doesn't this code show scroll bars?

shouldn't $WS_HSCROLL tell it to draw scroll? That string obviously doesn't fit in that gui, and scroll bar is needed.

$Form1 = GUICreate("Task Manager pre alpha", @DesktopWidth, 443, 0, 0)
$ListView1 = GUICtrlCreateListView("Caption|CommandLine|CreationClassName|datetime CreationDate|CSCreationClassName|CSName|Description|ExecutablePath|uint16-ExecutionState|Handle|HandleCount|datetime InstallDate|KernelModeTime|MaximumWorkingSetSize|MinimumWorkingSetSize|Name|OSCreationClassName|OSName|OtherOperationCount|OtherTransferCount|PageFaults|PageFileUsage|ParentProcessId|PeakPageFileUsage|PeakVirtualSize|PeakWorkingSetSize|Priority|PrivatePageCount|ProcessId|QuotaNonPagedPoolUsage|QuotaPagedPoolUsage|QuotaPeakNonPagedPoolUsage|QuotaPeakPagedPoolUsage|ReadOperationCount|ReadTransferCount|SessionId|Status|TerminationDate|ThreadCount|UserModeTime|VirtualSize|WindowsVersion|WorkingSetSize|WriteOperationCount|WriteTransferCount", 0, 5, @DesktopWidth, 430,BitOR($LVS_REPORT,$LVS_SINGLESEL,$LVS_SHOWSELALWAYS,$WS_HSCROLL,$WS_VSCROLL))
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
     Case $GUI_EVENT_CLOSE
         Exit

    EndSwitch
WEnd

E1M1,

Because you need data in the ListView for the scrollbars to be activated: :)

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <ListviewConstants.au3>
$sData = "Caption|CommandLine|CreationClassName|datetime CreationDate|" & _
  "CSCreationClassName|CSName|Description|ExecutablePath|uint16-ExecutionState|" & _
  "Handle|HandleCount|datetime InstallDate|KernelModeTime|MaximumWorkingSetSize|" & _
  "MinimumWorkingSetSize|Name|OSCreationClassName|OSName|OtherOperationCount|" & _
  "OtherTransferCount|PageFaults|PageFileUsage|ParentProcessId|PeakPageFileUsage|" & _
  "PeakVirtualSize|PeakWorkingSetSize|Priority|PrivatePageCount|ProcessId|" & _
  "QuotaNonPagedPoolUsage|QuotaPagedPoolUsage|QuotaPeakNonPagedPoolUsage|" & _
  "QuotaPeakPagedPoolUsage|ReadOperationCount|ReadTransferCount|SessionId|" & _
  "Status|TerminationDate|ThreadCount|UserModeTime|VirtualSize|WindowsVersion|" & _
  "WorkingSetSize|WriteOperationCount|WriteTransferCount"
$Form1 = GUICreate("Task Manager pre alpha", @DesktopWidth, 443, 0, 0)
$ListView1 = GUICtrlCreateListView($sData, 0, 5, @DesktopWidth, 430, BitOR($LVS_REPORT,$LVS_SINGLESEL,$LVS_SHOWSELALWAYS,$WS_HSCROLL,$WS_VSCROLL))
GUICtrlCreateListViewItem($sData, $ListView1)
GUISetState(@SW_SHOW)
While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
    Case $GUI_EVENT_CLOSE
        Exit
    EndSwitch
WEnd

And note the best way to write long lines of code - the continuation operator is very useful! :)

All clear? :mellow:

These 2 styles ($WS_HSCROLL,$WS_VSCROLL) are windows GUI styles, and probably won't work as intended on a Listview. Also, you have nothing in your listview so there won't be a scrollbar on it until something is placed in to it.

Here's an example showing what I mean:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <ListviewConstants.au3>
$Form1 = GUICreate("Task Manager pre alpha", @DesktopWidth, 443, 0, 0)
$ListView1 = GUICtrlCreateListView("Caption|CommandLine|CreationClassName|datetime CreationDate|CSCreationClassName|CSName|Description|ExecutablePath|uint16-ExecutionState|Handle|HandleCount|datetime InstallDate|KernelModeTime|MaximumWorkingSetSize|MinimumWorkingSetSize|Name|OSCreationClassName|OSName|OtherOperationCount|OtherTransferCount|PageFaults|PageFileUsage|ParentProcessId|PeakPageFileUsage|PeakVirtualSize|PeakWorkingSetSize|Priority|PrivatePageCount|ProcessId|QuotaNonPagedPoolUsage|QuotaPagedPoolUsage|QuotaPeakNonPagedPoolUsage|QuotaPeakPagedPoolUsage|ReadOperationCount|ReadTransferCount|SessionId|Status|TerminationDate|ThreadCount|UserModeTime|VirtualSize|WindowsVersion|WorkingSetSize|WriteOperationCount|WriteTransferCount", 0, 5, @DesktopWidth, 430, BitOR($LVS_REPORT, $LVS_SINGLESEL, $LVS_SHOWSELALWAYS, $WS_HSCROLL, $WS_VSCROLL))
GUICtrlCreateListViewItem("1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16|17|18", $ListView1)
GUISetState(@SW_SHOW)
#endregion ### END Koda GUI section ###
While 1
 $nMsg = GUIGetMsg()
 Switch $nMsg
  Case $GUI_EVENT_CLOSE
   Exit
 EndSwitch
WEnd

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
