[feature request] Preset Browser broadcasters

[d.healey]

@Christoph-Hart I think I was getting the segfault because my ScriptEditors were missing the new ScriptFile tag. I've added this into the XML and HISE is opening now.

A little example for anyone who wants to use this. fltPresetBrowser is the id of my preset browser floating tile.

    // Broadcaster
    const bc = Engine.createBroadcaster({"id": "PresetBrowser", "args": [component, obj]});
    
    bc.attachToComponentMouseEvents(["fltPresetBrowser"], "Clicks Only", "");
    
    bc.addListener("mouseAction", "Mouse action for preset browser", function(component, obj)
    {
        Console.print(trace(obj));
    });

I've added a couple of properties:

int selectedRow = lb->getSelectedRow();
String file = column->getFileForIndex(rowNumber).getFileName();

For file I had to add the getFileForIndex() function in presetBrowserComponents.h.

This works, but what I'd really like is for the file to actually be the file object instead of a filename/path. But when I try that I get an error:

error: cannot convert ‘juce::File’ to ‘const juce::var&’
  955 |                                 dyn->setProperty("file", file);
      |                                                          ^~~~
      |                                                          |
      |                                                          juce::File

Any idea how I can handle the conversion?

[Christoph Hart]

@d-healey the preset browser can't create scripting file objects (also the JSON object should only contain Strings or primitive values), but if you use File::getFullPathName() you can create a file object with FileSystem.fromAbsolutePath() in your script function.

[d.healey]

@Christoph-Hart Ah that's a good idea, thanks for the explanation.

[d.healey]

@Christoph-Hart bool selected = lb->isRowSelected(rowNumber); is always returning true, even for the expansion column, any suggestion?

[Christoph Hart]

@d-healey well after you clicked on it, it‘s selected, no?

[d.healey]

@Christoph-Hart Not for the expansions column, you can click again to deselect

[DanH]

@d-healey didn't we discuss having a 'Factory' folder in the Expansions column so users could navigate back to the 'Factory' presets rather than clicking the expansion name again?

[d.healey]

@DanH Yeah that's another way to do it. But in my case I don't want any factory presets.

[Christoph Hart]

Actually I'm not sure if the juce::ListBox class can have a "deselect" action, so you would need to hack around in there.

[d.healey]

@Christoph-Hart I think I'll just track the selected index in my script and if the index is the same as the last index I know it's been deselected :)

[d.healey]

Am I being silly or is the favourite button state obj.buttonState inverted? Aha! It triggers on mouse up not mouse down :)
