ListView scrollbar

5 posts in this topic

#1 ·  Posted (edited)

Is there any possibility to hide the listview vertical scrollbar, but be able to scroll? 

I've tried something with a listbox (the script below), but a listview gives more options (icons, multiple columns etc.):

#include <GUIConstantsEx.au3>
#include <GUIListBox.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

Global $hForm1, $hForm2, $hPic
$hForm1 = GUICreate("Form1", 150, 200,-1,-1,BitOR($WS_SYSMENU, $WS_POPUP), $WS_EX_LAYERED)

GUISetBkColor(0x000000)
$ListB = GUICtrlCreateList("", 10, 10, 130, 180, BitOR($LBS_NOTIFY,$LBS_SORT,$WS_BORDER), 0)
For $i = 1 To 50
    GUICtrlSetData(-1, "Line" & $i)
Next
GUICtrlSetFont(-1, 8, 400, 0, "Arial")
GUICtrlSetColor(-1, 0xFFCC00)
GUICtrlSetBkColor(-1,0x222222)

$hPic = GUICtrlCreatePic("", 100, 10, 50, 180)
WinSetTrans($hForm1,"",200)
GUISetState()

$pos1=WinGetPos($hForm1)
$hForm2 = GUICreate("Form2", 25, 49, $pos1[0]+$pos1[2]-40, $pos1[1]+60, BitOR($WS_SYSMENU,$WS_POPUP), $WS_EX_LAYERED)
GUISetBkColor(0x000000)
$hUp = GUICtrlCreateIcon(@ScriptDir & "\up.ico", -1, 4, 4, 16, 16)
GUICtrlSetCursor($hUp,0)
GUICtrlSetTip($hUp,"Up")
$hDown = GUICtrlCreateIcon(@ScriptDir & "\down.ico", -1, 4, 28, 16, 16)
GUICtrlSetCursor($hDown,0)
GUICtrlSetTip($hDown,"Down")
GUICtrlCreatePic("", 0, 0, 24, 48)
WinSetTrans($hForm2,"",50)
GUISetState(@SW_HIDE, $hForm2)

While 1
    Sleep(10)
    Local $mcur = GUIGetCursorInfo($hForm1)
    If $mcur[4] = $hPic then
        GUISetState(@SW_SHOW, $hForm2)
    Else
        GUISetState(@SW_HIDE, $hForm2)
    EndIf
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            GuiDelete()
            Exit
        Case $hDown
            While 1
                Sleep (10)
                Local $ind = _GUICtrlListBox_GetCurSel($ListB)
                _GUICtrlListBox_SetCurSel($ListB,$ind+5)
                ExitLoop
            WEnd
        Case $hUp
            While 1
                Sleep (10)
                Local $ind = _GUICtrlListBox_GetCurSel($ListB)
                If $ind<5 Then _GUICtrlListBox_SetCurSel($ListB,0)
                _GUICtrlListBox_SetCurSel($ListB,$ind-5)
                ExitLoop
            WEnd
    EndSwitch
WEnd

When you move the mouse over the right part of the listbox, it will appear a customized scrollbar that works with the listbox... Any chance with a listview? I've searched (and read and still do), but I didn't figure this out.

I've attached the icons used in the script, to see what I mean.

Thanks in advance! (for pointing me in the right direction)   :blink:

It's unfinished code and does not address several issues.

Next time try linking to the original post and/or accrediting the author.

ListView without ScrollBar ?


I see fascists...
