[Q] Is accessible (get/set) for Brush Settings' Lock features?

What do I think about locks. You can use the "reset_tool ()" function after you receive the "currentToolOptions" descriptor. It will reset all locks. After that you can change only the necessary required parameters and call the "set" command as usual.

function reset_tool()
    {
    try {
        var desc = new ActionDescriptor();
        var ref = new ActionReference();
        ref.putProperty( charIDToTypeID( "Prpr" ), charIDToTypeID( "CrnT" ) );
        ref.putEnumerated( charIDToTypeID( "capp" ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) );
        desc.putReference( charIDToTypeID( "null" ), ref );
        executeAction( charIDToTypeID( "Rset" ), desc, DialogModes.NO );
        }
    catch (e) {}
    }

Thank you very much for tips.

> It's not entirely clear what you are looking for.

Main purpose is increment/decrements brush values on UI for Opacity, Flow, Exposure, and Strength as similar the code you provided on following thread for Brush's Hardness.

I tried to apply similar way to Opacity, Flow, Exposure, and Strength.

But it did not work well with 2 following issues.

1) Brush Settings' Checkboxes get reset (green rectangle area of original post above)

2) Brush Settings Details get reset (red rectangle area of original post above)

I think this is descriptors structure is different and reset unset properties to default.

One finding is that if the Brush Setting's Lock Icon is locked (yellow area on original post) , it does not get effected by resetting.

But Opacity, Flow, Exposure setting get effected.

So I tried to lock the setting before set Opacity etc values.

The object properties seems not contain the Lock icon values.
