Any more precise slider?

[E1M1]

When I click on slider, it always overruns the right position. I was wondering if there's any more precise slider available. Like UDF or something.

GUICreate("slider", 220, 100, 100, 200)

$slider1 = GUICtrlCreateSlider(10, 10, 200, 30)
GUICtrlSetLimit(-1, 200, 0) ; change min/max value
GUICtrlSetData($slider1, 45) ; set cursor

GUISetState()

Do
$msg = GUIGetMsg()
Until $msg = -3

Looks fine to me

I mean when you don't drag it but click it.

E1M1,

It is a feature/bug (you decide which) of the slider control - this article explains why.

Perhaps someone versed in C might try to convert the suggested subclass procedure into AutoIt code.

Thanks.

E1M1,

Does this get the thumb close enough to the mouse for you?

#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>

$iSlider_X = 10
$iSlider_W = 400
$iMargin = 8 ; This value works for me - you may have to adjust it

$hGUI = GUICreate("Test", 500, 500)

$cSlider = GUICtrlCreateSlider($iSlider_X, 10, $iSlider_W, 20)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $GUI_EVENT_PRIMARYDOWN
            $aInfo = GUIGetCursorInfo($hGUI)
            If $aInfo[4] = $cSlider Then
                $iX = ($aInfo[0] - $iSlider_X - $iMargin) * 100 / ($iSlider_W - ($iMargin * 2))
                GUICtrlSetData($cSlider, $iX)
            EndIf
    EndSwitch

WEnd

Much simpler than subclassing.

And you should remember this when working with sliders:

QSlider only provides integer ranges. Note that although QSlider handles very large numbers, it becomes difficult for users to use a slider accurately for very large ranges.

(from here)
 
Though the description is for a QSlider control, it applies to all sliders (that I have seen).
