solid-nodegui

A solidjs renderer for NodeGui.

This is just a proof-of-concept with just some Qt widgets implemented and flex layout powered by facebook's Yoga layout engine (the same one used by react-native).

This shows just how simple it would be to create a solid-native renderer. That runs right on top of a native renderer like Qt.

---

Most nodegui renderers implement react-native-style components like view, text, and button. solid-nodegui stays close to Qt and nodegui and simply wraps existing widgets in solid components.

There is no event delegation and events are attached to the specific widget, solid-nodegui follows solid's style with on:* prop style. QPushButton's click event is clicked so solid-nodegui's is on:clicked.

Widgets and their solid wrappers are registered in the WidgetRegistry. solid-nodegui delegates widget-specific work to the registry making it easily extensible. See below.

Set up

Run npm install to download and install the dependencies.

Building

Build solid-nodegui

cd packages/solid-nodegui && npm run build

Build the calculator app

npm run build will build the code in src and produce a bundle file in dist.

cd packages/calculator && npm run build

Running the calculator app

npm run run will run the bundled application. Note, you will have to build it first.

Packaging the calculator app

npm run package will run Jam Pack NodeGui with a configuration file to create the relevant packages for the current operating system this is running on. The output appears in tmp-jam-pack-nodegui/jam-pack-nodegui-work/.

Configured Scripts

• build - Runs all of the build steps.
• run - Runs the application from the dist folder.
• package - Build packages for the application. The output appears in tmp-jam-pack-nodegui/jam-pack-nodegui-work/

Widget wrappers

import * as gui from "@nodegui/nodegui";
import {
  EventProps,
  WidgetEventProps,
  handleEvents,
  WidgetRegistry,
} from "solid-nodegui";

// make the wrapper
function QDateTimeEdit(
  props: {
    id?: string;
    dateTime: gui.QDateTime;
  } & EventProps<gui.QDateTimeEditSignals> &
    WidgetEventProps
) {
  let node: gui.QDateTimeEdit;
  // events are automatically handled
  const local = handleEvents(() => node, props);
  return <q-date-time-edit ref={node} {...local} />;
}

// register the widget
WidgetRegistry.registerWidget("q-date-time-edit", {
  widget: gui.QDateTimeEdit,
  setProperty(node, name, value, prev) {
    if (name === "dateTime") {
      node.setDateTime(value as gui.QDateTime);
      return true;
    }
  },
});

// render it
const dateTime = new gui.QDateTime();
<QDateTimeEdit
  dateTime={dateTime}
  on:dateTimeChanged={(qDateTime) => {
    console.log(
      qDateTime.date().year(),
      qDateTime.date().month(),
      qDateTime.date().day(),
      qDateTime.time().hour(),
      qDateTime.time().minute(),
      qDateTime.time().second()
    );
  }}
/>;
