MinimalComps2 v1.4.0

minimalcomps

I gotta admin, I’m not crazy about how the 2 in MinimalComps2 works with the semantic versioning. Version 1.4 of version 2? Whatever.

Anyway… VERSION 1.4.0!!!

No new components this time, but some super useful features, as well as a bunch of bug fixes.

Defaults

There are some new defaults in the Defaults object. These are mostly useful if you are creating a bunch of components that need some specific property that is not settable in the constructor. Like HSlider’s text position. Rather than doing something like:

const hs1 = new HSlider(panel, x, y, "one", 0, 0, 100);
hs1.textPosition = "left";
const hs2 = new HSlider(panel, x, y, "two", 0, 0, 100);
hs2.textPosition = "left";
const hs3 = new HSlider(panel, x, y, "three", 0, 0, 100);
hs3.textPosition = "left";

You can do:

Defaults.hslider.textPosition = "left";
const hs1 = new HSlider(panel, x, y, "one", 0, 0, 100);
const hs2 = new HSlider(panel, x, y, "two", 0, 0, 100);
const hs3 = new HSlider(panel, x, y, "three", 0, 0, 100);

You can see all the properties that use this technique here.

Chainable setters

Another ease of use improvement. Basically, all settable properties now have a setter method that returns the current instance of the component. This lets you set a bunch of properties in a row and assign the result back to a variable that holds the instance. Especially useful for those properties that aren’t in the constructor, but some people don’t like the long constructors either. Along with this work, I made sure that just about all the constructor parameters are optional and have sensible defaults.

So now, if you want, you can do stuff like this:

const velSlider = new HSlider(panel)
  .setText("velocity")
  .move(x, y)
  .setSize(200, 30)
  .setHandleSize(30)
  .setMin(50)
  .setMax(200)
  .setValue(175)
  .setTextPosition("left")
  .setDecimals(2)
  .addHandler(handleSlider);

Maybe a little overboard with that example, but you get the idea.

Binding

Binding is one of my favorite features. It turns this:

new HSlider(panel, 20, 20, "velocity", 0, 0, 100, event => model.velocity = event.target.value;

to this:

new HSlider(panel, 20, 20, "velocity", 0, 0, 100)
  .bind(model, "velocity");

I wrote about this in a lot more detail here: https://www.minimalcomps2.com/docs/bind/ . So I’ll leave you with that.

Other stuff

I also upgraded the API docs a bit, both in style and content.

A bunch of bug fixes, more demos

Also, check my last few posts here for some more examples of the components in action.

I hope to get a showcase up eventually, linking to other real world uses of the library beyond my own. So if you do something with these, let me know!
