Print array index

Dan Korneff

I'm trying to get familiar with using an index to show/hide controls, but it's not clicking in my brain yet... Also my first time using radiogroups.
As a test, I have a simple instrument with 2 samplers. The user interface has buttons (in radiogroup) to select each sampler, and a second set of buttons (in separate radiogroup) to show/hide controls of the samplers.

All buttons have been put into associated arrays, I've created a Callback function for the buttons, and I'm using the onControl section to show/hide content.

What I'm attempting to do is use the index of my SamplerSelectButtonArray to show/hide knobs in the GainSliderArray or PanSliderArray.
Any thoughts are appreciated.

@dustbro

This line var y = ControlSelectButtonArray.indexOf(component); You should use local rather than var.

This line GainSliderArray.showControl(index); Where is index coming from?

Dan Korneff

@d-healey said in Print array index:

This line GainSliderArray.showControl(index); Where is index coming from?

I thought:

local index = SamplerSelectButtonArray.indexOf(component);

Is that only available in my buttonCallback function?

d.healey

@dustbro Ya, that's why it's local :) post a HISE snippet, I think I will be able to help you more then.

looks like this is causing it:

if(x == true)
                
            {
                showPageGain(y);}
            else
                {showPageGain(2);
            }
            
            
            if(y == true)
            {
                showPagePan(y);}
                
            else
                {showPagePan(2);
            }

Which HISE version are you using? I remember fixing a crash a few weeks ago that happened when you try to iterate over an object that isn't iteratable (eg. a module reference obtained by Content.getComponent() et al.), which is exactly what you trying to do with:

for(k in GainSliderArray[0]) 
{
    k.showControl(pageIndex == 0);
}

This is not how the for(... in ...) loop works. You want to iterate over the array, not the first element of it, so you need to remove the array subscription from the iterated object:

for(k in GainSliderArray) 
{
    k.showControl(pageIndex == 0);
}

Dan Korneff

I've gotten much closer to the goal.... just one thing left. Switching between Sampler1 and Sampler2 doesn't update my display until I select the Gain/Pan button. Any suggestions?

@christoph-hart The build is May3 2018. I'll update to the latest today.

@dustbro The latest is in the develop branch but there might be bugs.

@d-healey Overall functionality of the newest version is quite more stable than what I was using. Keeping my eyes open for bugs as you suggested.
