How to synch two sliders smoothly and continuously?

4 posts in this topic

Hello,

trying to set up a multizone audio solution für MediaPortal that ist controllable via a PC based radio controlled remote, I came to AutoIt - and I got hooked :D

As the "kx Mixer" I need to control with the remote doesn't seem to be entirely standard window and even with the help the forum it was not possible to find a way to get the checkbox status (http://www.autoitscript.com/forum/index.php?showtopic=39203&hl=), I decides to make an own GUI to mirror the settings of the kxM Mixer.

Taking into account that I have almost no idea of programming (except some lines of perl and word5 macros 20 years ago), it was a hard job for me - but thanks to the excellent documentation and the information I found in the forum, I've managed to get the basic things working (see below).

When you are finished laughing at my code :P, I have three question left:

I would love to learn how to

a) send the {UP} and {DOWN} commands to the kx volume sliders while moving the AutoIt GUI sliders, and

:) to do this smoothly and in a reliable manner (i.e. in a way that even when messing around with the GUI slider, no up or down is forgotten.) This is important because the idea depends on having the slider position in the kx mixer and the GUI always synchronized, and

c) as I want to use the GUI for a little touchscreen, the volume buttons should work like "Send UPs or DOWNs while pressed, stop when released". But in spite of profound searching, I couldn't find something like "GUIbutton presses"

Fot :D I have tried a modified version of a script I found in the forum (for testing purposes I put the standard windows mixer instead of the kx mixer - I know that normally one would control the standard windows mixer with SoundSetWaveVolume...):

#include <GUIConstants.au3>

GUICreate("Test")

$Zahlenbox = GUICtrlCreateSlider ( "0000", 100, 300,40,-1,$ES_NUMBER)
$Textbox = GUICtrlCreateInput ( "This is a test", 2, 30,70,-1) 
$Textanzeige = GUICtrlCreateLabel ( "text", 100, 2, 100, -1)

GUISetState()

$changed = GUICtrlRead ($Textanzeige)

While 1
   $msg = GUIGetMsg()
   If $msg = $GUI_EVENT_CLOSE Then ExitLoop
   If $changed <> GUICtrlRead ($Zahlenbox) & " - " & GUICtrlRead ($Textbox) Then
      GUICtrlSetData ($Textanzeige, GUICtrlRead ($Zahlenbox) & " - " & GUICtrlRead ($Textbox))
      IF $changed > GUICtrlRead ($Zahlenbox) Then
          $move_slider_down = ($changed - GUICtrlRead($Zahlenbox) ) * 5
          ControlSend ( "Lautstärkeregelung", "", 2001, "{DOWN " & $move_slider_down & "}")
          SLEEP(250)
      EndIf
      If $changed < GUICtrlRead ($Zahlenbox) Then
          $move_slider_up = (GUICtrlRead($Zahlenbox) -$changed) * 5
          ControlSend ( "Lautstärkeregelung", "", 2001, "{UP " & $move_slider_up & "}")
          SLEEP(250)
        EndIf
      EndIf

So my question: Is there any way to get this working with AutoIt?

Unfortunately I don't believe that it's possible to do this.

I would suggest writing a loop that checks the status of the sliders on the AutoIt window every 100ms (for example) and updates the sliders on the other window if the AutoIt slider has changed. (I'm quite certain that I've been able to adjust external sliders without sending keystrokes to them, but I don't remember how at this moment.)

ok, that might be an idea. I have already experimented with little "sleeps" to give the external slider some time to crawl up or down, but the results have not been satisfactory.

I think that I had better forget the idea of the synching sliders and concentrate on the normal buttons. However, my initial question concerning their behaviour hasn't found an answer either: the volume buttons should work like "Send UPs or DOWNs while pressed, stop when released", or in other words: as I want tu use the GUI on a little touchscreen, volume should go continuously up while the big UP button is pressed and should go down while the DOWN button is pressed.

Hey, is this http://en.wikipedia.org/wiki/Heidelberg_Heights,_Victoria ? How did it get its name? Perhaps I have some family over there which I don't know :)

Best regards
