Marty's slider

[conde]

Hi,
I'm using Marty's horizontal slider in 2 cards. After moving the slider knob "k" from 100 to i.e. 40 and going to card 2 the value is 40 but the knob is on position 100. What can I do to move the knob on card 2 to the pos of 40?

Thanks for helping.

Hi conde,

EDIT:
Ah, found it, will take a look...

Whatever Marty's slider is, can you store the thumbPosition (or whatever so corresponds) in a custom property and reset it on opencard?

Hi,

It is possible using group to do that ( tested with Marty Slider)

1. Set the sharedText of fld "theValue_h" to true
2. Select btn "k", img "Hsliderbar", fld "theValue_h of the horizontal Slider
3. Clic at "Group" on the toolbar
4. Set the name of the group to "myScrollbar"
5. Set the behaviorBackground of group "myScrollbar" to true
6. Type "new cd" in the messagesBox, the new cd have the group "myScrollbar"
and it keep the value and position of the slider

Best regards

Many, many thanks to Jean-Marc. As a newbie I would never have thought with the behaviorBackground.
Today my trial period is over and I'm going now to order Livecode. Then I will try Jean-Marc's suggestion.

This forum here is a nice comuntity with many helpful people. I hope that someday I can help others.

Kind regards,

Sorry - I'm too stupid for math.
The script of Marty’s horizontal slider:

Code: Select all

on mouseDown
  # INSERT YOUR MINIMUM (LEFT) VALUE
  put 2000 into minValue --in my case = wait 2000 milliseconds (30 BPM)
  # INSERT YOUR MAXIMUM (RIGHT) VALUE
  put 200 into maxValue --in my case = wait 200 milliseconds (300 BPM)
  
  # GET THE OFFSET OF THE CLICK SPOT AND CENTER OF THE BTN
  # THIS WILL PREVENT THE BTN FROM JUMPING WHEN YOU START TO DRAG
  put (the mouseH - item 1 of the loc of me) into cX
  
  # the number you see added or subtracted at the end of the next 3 lines
  # is to tweak the position of the slider button so it stops where you want
  # THIS IS IN ADDITION TO ADDING THE VALUE OF cX
  put (the left of image "BGSliderRate")+(the width of me/2)+cX -12 into Lstop
  put (the right of image "BGSliderRate")-(the width of me/2)+cX +12 into Rstop
  put item 2 of the loc of image "BGSliderRate" into yLoc
   put (maxValue-minValue)/(Rstop-Lstop) into scaleFactor
  put true into canMove
end mouseDown

on mouseMove x,y
  if not canMove then exit mouseMove
  put min(Rstop,max(Lstop,x)) into xLoc
  set loc of me to xLoc-cX,yLoc
  # you may need to add values to following: xLoc and yLoc
  # to position the value fld where you want
  set loc of fld "theValue_h" to xLoc-cX,yLoc+20
  # The following line calculates the value which you would want to
  # also put into use for the actual functioning of the slider
  put round((xLoc-Lstop)*scaleFactor)+minValue into fld "theValue_h"
  put round((xLoc-Lstop)*scaleFactor)+minValue into pBPM
end mouseMove

Now I would like to see the BPMs in the fld "theValue_h" ???

Thanks for helping.

It's a pity. No response? Or is this posting in the wrong category?

Hi Conde,

I don't really understand what you want. Your script should work in the context of Marty's Slider.

Here is a version of the horizontal slider with min 200 and max 2000 that displays the value below the slider in field "theValue_h"

Bernd - danke for your answer and stack.
My problem is: in the script I've modified (code see above) the minValue = 2000 and maxValue = 200. The variable pBPM goes to a wait command. Wait 2000 milliseconds (30 BeatsPerMinute - slider knob left = slow) and wait 200 milliseconds (300 bpm - slider knob on the right = fast). The slider works fine in the wait command. What I mean is that I can see in “the_Value_h“ the real beats per minute.

Danke für Deine Mühe.

Hi Guera,

I did not get that you wanted the "real" beats to show up in the field.

try to replace the last lines of the mouseMove handler with this:

Code: Select all

     put round((xLoc-Lstop)*scaleFactor)+minValue into tRawValue
     put round(60000/tRawValue) into fld "theValue_h"
     put round((xLoc-Lstop)*scaleFactor)+minValue into pBPM
end mouseMove

The beats should be in field "theValue_h"

Kind regards and greetings to Stuttgart
