B4A Class Input Slider Class

stevel05 · Jun 18, 2012

I'm not quite sure where to post this, but while testing the beta, I came up with an input slider class that allows simple use of images to create interesting sliders similar to the seek bars we are used to.

I thought it may be useful to share as it's using a few of the new functions (all without problems I should say). And obviously you can tailor it to your needs.

If you get a chance to have a look, let me know how it works for you.

V1.00 attached

@Erel. perhaps we should have a new section in the forum for shared classes/code modules as I think these will far outnumber libraries in the future.

19/6/2012 - V1.01 attached
07/02/2014 V1.02 - Added released callback, called when the slider is released.
07/02/2014 Added InputSlider CustomView V1.00 (iscv.zip) see post #7
15/02/2015 Added InputSlider CV1-1 minor updates required for MidiSystem, Download and compile to library.
NOTE: This will break existing code as it uses get/setters for most variables, so if you have an existing app, use the old version. If you have compiled it to a library, give this one a different name before compiling.

3/4/2017 - InputSlider1-2 : Added a Steps options to allow discrete value changes. see post #22

"Y" And how to change the axis. To the upper position and the maximum value was at minimum lower. For vertical slider ...

Hi all,

I like very much this Slider Class and I tried to do a change I need without success , I'd like to use a discrete value different than 1.

For example I want a slider with values from 0 to 20 every 5.

Someone can help me?

Thanks

EDIT: I realized it's an abovious question, I simply set the range from 0 to 4 and then multiply by 5 all the results...

@SandroB4A Check InputSlider1-2.zip in the first post. I have added a Steps method, it should do what you want.

If you are using a different version, you should be able to copy the relevant code to that version.

Thank you, works fine!

Hi
This is a great slider !! I am having one small problem, I have set the maxval to 100 however when I slide the slider to the right the value shows as 577.
I need the slider to go from 0 to 100...
Regards

Duncan

Can you post your code

Duncan H Williamson · Jun 26, 2017

B4X:

InputSlider1.SetSliderColor(Colors.blue)
    InputSlider1.SetMaxVal(100)
    InputSlider1.SetValue(0)
    InputSlider1.SetDiscrete(True)
    InputSlider1.SetPointerCount(1)

this is in activity create

B4X:

Sub inputslider1_ValuesChanged(Values() As Float)
   Label1.Text = NumberFormat(Values(0), 1, 0)
End Sub

end this sub should display 0 to 100

OK, you are using DaveW's version. I think you need to set the number of pointers before anything else try changing your code to:

B4X:

    InputSlider1.SetPointerCount(1)
    InputSlider1.SetSliderColor(Colors.blue)
    InputSlider1.SetMaxVal(100)
    InputSlider1.SetValue(0)
    InputSlider1.SetDiscrete(True)

Thanks Steve, that has sorted the problem
