Scrollbars Made Easy - New version 27 Jan 22

HolmesShelock · May 2, 2011

Having seen the expertise of MVPs over here (which, of course, includes you), makes me suffer from inferiority complex. Only one word for you & your scrollbar control - mind blowing.

HolmesShelock,

makes me suffer from inferiority complex

Might I suggest using that feeling positively to spur you on to become a better AutoIt coder? That is certainly what I (and I am sure many of the others here) did. :unsure:

Surely I'll try to learn more & more. Posted Image

FMS,

Those constants are declared in WindowsConstants.au3 - if I redeclare them in the UDF we get a "previously declared as a 'Const'" error. I felt that most people who wanted to use scrollbars would also be using that #include file.

So just add #include <WindowsConstants.au3> to your script (as it is in the examples) and all will be well. :unsure:

Got 2 questions:

1) can you make scrolling by just moving a mouse cursor (with shift pressed) or just keys like up/down/left/right

2) how can i get X,Y coords from scrolled area ? (under the mouse cursor)

I tryed to get coords by

Enforcer,

And I have 2 answers! :alien:

- 1. Look for the mouse moving when "Shift" is pressed and then send a suitable message to the scrollbars.

- 2. You need to work out how much the underlying GUI has been scrolled and then add the mouse coordinates based on the client area. Fortunately the UDF already holds the necessary values to do the calculations.

I hope this short example will show you how to amend your own script - I have used GUIRegisterMsg to look for the mouse moving: :huh2:

[New Version] - 20 Jan 12

Added functions to restore scrollbar position after a minimize/restore cycle:

For GUIScrollbars_Ex there are 2 functions: _GUIScrollbars_Minimize and _GUIScrollbars_Restore - called on the relevant events occurring. This is needed because of the way the UDF deals with the scrollbars it generates.

For GUIScrollbars_Size there is a single function: _GUIScrollbars_Restore.

The second example for each UDF has been modified to use these new functions. Thanks to rover and czardas for developing the code.

New UDFs, examples and zip file in first post.

Thanks for the latest update Melba23! That problem with the minimizing and restoring destroyed my feeble mind.

LaCastiglione,

Thank rover and czardas - all I did was incorporate their code.

Thank you for easy using of wide window with help your UDF.

Script "Beyond 256" is showing unicode chars with code more than $CodeShift. It's good idea to shift area of view by $CodeShift.

#include <GUIConstantsEx.au3>
#include "StaticConstants.au3"
#include "GUIScrollbars_Ex.au3"
Global $nX = 32, $nY = 40, $nDX = 50, $nDY = 25
Global $CodeShift = 0x300
Global $hLabel[$nX+1][$nY+1]
$hGUI = GUICreate("Beyond 256", 500, 500)
GUISetBkColor(0xFFFFFF, $hGUI)
for $i = 1 to $nX
for $j = 1 to $nY
  $hLabel[$i][$j] = GUICtrlCreateLabel(ChrW($CodeShift+($j-1)*$nX+$i), ($i-1)*$nDX, ($j-1)*$nDY, 40, 20, BitOr($SS_CENTER,$SS_SUNKEN))
GUICtrlSetBkColor(-1, 0xFFFFAA)
GUICtrlSetColor(-1, 0x000088)
next
next
_GUIScrollbars_Generate($hGUI, $nX*$nDX, $nY*$nDY)
GUISetState()
While 1
  $Msg = GUIGetMsg()
  Switch $Msg
  Case $GUI_EVENT_CLOSE
   Exit
  Case $GUI_EVENT_RESTORE
   _GUIScrollbars_Restore($hGUI)
  Case $GUI_EVENT_MINIMIZE
   _GUIScrollbars_Minimize($hGUI)
  Case Else
   for $i = 1 to $nX
    for $j = 1 to $nY
     if $Msg = $hLabel[$i][$j] then
      MsgBox(0,"","You click char: "& @CrLf & ChrW($CodeShift+($j-1)*$nX+$i) & @CrLf & 'Hex code = ' & '0x' & Hex($CodeShift+($j-1)*$nX+$i,4) )
      ExitLoop(2)
    endif
   next
   next
EndSwitch
WEnd

Thanks, Just what I was looking for.

Is there a way to remove or disable the scrollbar?

So that in the GUIScrollbars_Size_Example_2.au3 script the scrollbar would just disappear when we would have less than 6 labels. We only need the vscroll when a control really goes over the clientarea.

I skimmed the UDF and this thread but couldn't find information.

Hawk,

You just need to check if the required scrollbar size is less than the height of the GUI:

Case $hButton
    Do
        $iCount = Number(InputBox("Resize scroll area", "Select number of labels to display (min 5)", "", "", 240, 130))
    Until $iCount > 4

    _Draw_labels($iCount)

    If ($iCount + 1) * 50 <= 300 Then
        _GUIScrollBars_ShowScrollBar($hGUI, $SB_VERT, False)
    Else
        _GUIScrollBars_ShowScrollBar($hGUI, $SB_VERT, True)
        $aRet = _GUIScrollbars_Size(0, ($iCount + 1) * 50, 300, 300)
        _GUIScrollBars_SetScrollInfoPage($hGUI, $SB_VERT, $aRet[2])
        _GUIScrollBars_SetScrollInfoMax($hGUI, $SB_VERT, $aRet[3])
    EndIf

All clear?

Hawk · February 15, 2012

Yes thanks, everything clear.

I was looking for something like _GUIScrollBars_HideScrollBar() >_> Didn't know about the third parameter.

Edit: What I want to do is dynamically change the number of controls as well as their position and readjust the scrollbar to the correct size. I noticed that when I use ControlMove() or GUICtrlSetPos(), that controls will be moved to the current visible coordinates, not to the absolute GUI's coordinates.

Example: A control is at 0,500. The Vscrollbar is moved down, so that the visible clientarea starts at 0,400. If I do GUICtrlSetPos($control, 0, 0), the control will actually be moved to 0,450 because it takes the currently visible clientarea.

Taking your GUIScrollbars_Size_Example_2.au3, it can be reproduced by scrolling down, then pressing ENTER to activate the button, instead of clicking. Everything afterwards will be funny

Edit3: _GUIScrollBars_SetScrollInfoPos($hGUI, $SB_VERT, 0) before any moving fixes it for me.

Edit2: Also it seems that in any purpose just using _GUIScrollBars_ShowScrollBar($hGUI, $SB_VERT, False) is not enough. The window can still be scrolled with the mousewheel even when the scrollbar is hidden. Setting it to size 1 or so should hopefully fix that.

Edit4:

_GUIScrollBars_SetScrollInfoPage($hGUI, $SB_VERT, 0)

_GUIScrollBars_SetScrollInfoMax($hGUI, $SB_VERT, 0)

along with hiding it works for me.

Hawk,

Already solved here. But note that you need to use the GUIScrollbars_Ex UDF to create the scrollbars for this function work.

I also need ways to hide Scrollbars
