[feature request] Preset Browser broadcasters

[DanH]

@d-healey crossed wires I think - I just want the brower's functionality (so save, new, import etc) to be available outside of the browser window, so we can have the equivalent buttons wherever we like on the ui.

[Christoph Hart]

@DanH There should be enough API calls to create, save and import user presets using the file API.

[David 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.

[David Healey]

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.

[David Healey]

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

[David 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?

[David 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?

[David 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.

[David 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 :)

[David Healey]

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