Expansions / Combo Box + SampleMaps

[DanH]

@d-healey ok thanks.

So I'm looking in PresetBrowser.cpp line 616 and 691 as places of interest...

I've just realised that if I don't have the Expansion Column enabled in the Preset Browser then the presets won't switch at all when selecting expansions with the combo box (but I can set the column width to zero so I don't have to see it)

[DanH]

@d-healey Are either of these sections of use to me do you think?

[d.healey]

@DanH oh I thought you'd solved it by hiding the columns. I'll take a look when I'm back at my computer.

[d.healey]

You might just need a wrapper around this function - void PresetBrowser::rebuildAllPresets() - you might also need to include the set root file thingy but I don't know.

[DanH]

@d-healey ok thanks :) I'll come back to that in a sec.

I'm currently trying to get my combobox (SAMPLEBOX) to update with the samplemaps available in either an expansion or Factory mode. It's not really working however! I've tried to bend one of @Christoph-Hart's expansions examples to this purpose.

Any insight would be hugely welcome :)

const var expHandler = Engine.createExpansionHandler();

const var expansions = expHandler.getExpansionList();

const var expansionNames = [];

expansionNames.push("FACTORY");

for(e in expHandler.getExpansionList())
    expansionNames.push(e.getProperties().Name);
    

const var ExpansionSelector = Content.getComponent("ExpansionSelector");
ExpansionSelector.set("items", expansionNames.join("\n"));


inline function onExpansionSelectorControl(component, value)
{
	//Engine.setCurrentExpansion(component.getItemText());
	expHandler.setCurrentExpansion(component.getItemText());
};

Content.getComponent("ExpansionSelector").setControlCallback(onExpansionSelectorControl);

// Implement the expansion switch

inline function onExpansionSelectorControl(component, value)
{
	local expansionToLoad = component.getItemText();
	
	// We want the first item to reset the current expansion
	// so we need to change it to an empty string
	if(expansionToLoad == expansionNames[0])
        expansionToLoad = "";
    
	expHandler.setCurrentExpansion(expansionToLoad);
};

Content.getComponent("ExpansionSelector").setControlCallback(onExpansionSelectorControl);

inline function newcombobox(newExpansion)
{
    
    
    if(isDefined(newExpansion))
    {

        local cx = expHandler.getCurrentExpansion();
        local xs = cx.getSampleMapList();
        SAMPLEBOX.set("items", xs.join("\n"));

    }
    else
    {

        SAMPLEBOX.set("items", mySampleMapNames.join("\n"));
    }
    
    
}


expHandler.setExpansionCallback(newcombobox);

// Call it once with undefined so that it loads the root images
newcombobox(undefined);

You have to clear the items before you can replace them - not sure why, just a HISE quirk.

@d-healey lovely, seems to work so far, thanks!

@d-healey

So below is the combox box callback for selecting a sample map. I was hoping that 'sampleMaps' would update when switching between expansions but it doesn't (I don't think).

The combox displays the available sample maps, however it continues to select the corresponding sample maps from the factory list. The sampler in Hise even has the expansion's sample maps in its menu, but obviously the callback is processing the original 'sampleMaps' list. So I guess I need to make 'sampleMaps' dynamic somehow...

Any clues welcome

const var sampleMaps = Sampler.getSampleMapList();

inline function onSAMPLEBOXControl(component, value)
{
  Sampler1.asSampler().loadSampleMap(sampleMaps[value-1]);
};

Content.getComponent("SAMPLEBOX").setControlCallback(onSAMPLEBOXControl);

@DanH said in Expansions / Combo Box + SampleMaps:

It will if you use the previous example you posted

        local cx = expHandler.getCurrentExpansion();
        local xs = cx.getSampleMapList();

[DanH]

@d-healey I've done that (if that's what you mean). It feels like I need to push the list into 'sampleMaps' each time I switch expansion

[d.healey]

@DanH

I need to push the list into 'sampleMaps' each time I switch expansion

Instead of local xs = cx... you need sampleMaps = cx..

[DanH]

@d-healey hmmmm, getting the error:

Can't assign to this expression!

[d.healey]

@DanH Need more info.

[DanH]

@d-healey What would help?

[d.healey]

@DanH Seeing the error message :) What is the expression that can't be assigned?

[DanH]

@d-healey oh ha.... the expression is

sampleMaps = cx.getSampleMapList();

as suggested

[d.healey]

@DanH sampleMaps is a const, you can't overwrite a const.

[DanH]

@d-healey doh

[DanH]

@d-healey right, so now I need to get the factory sample maps back for the else statement, they currently stay in the expansion!

Is there a way to call 'factory' sample maps?

I've tried:

sampleMaps = Sampler1.asSampler().getSampleMapList();

[d.healey]

sampleMaps = Sampler.getSampleMapList();

Doesn't that work?
