Examples

Example 1: Add a simple goniometer

Goal: Add a goniometer in the center of the screen and toggled on and off.

To start, add a container layer to the layout and insert the goniometer.

{
  "name": "container",
  "type": "container",
  "classes": [
    "fullSize"
  ],
  "children": [
    {
      "name": "goniometer",
      "dataKey": "goniometer",
      "type": "goniometer",
      "rotation": "portrait",
      "lineSize": 4,
      "dotSize": 10,
      "staticLineColor": "#77b400",
      "referenceLineColor": "#F07D00",
      "centerDotColor": "#3CA937",
      "fontSize": "30dp",
      "textAlign": "alignCenter",
      "classes": [
        "textWhite"
      ],
      "constraints": [
        {
          "type": "pos",
          "x": "0",
          "y": "0"
        },
        {
          "type": "size",
          "width": "100%"
        },
        {
          "type": "aspectRatio",
          "ratio": "1.0"
        }
      ]
    }
  ]
}

A goniometer was added to the layout with a portrait rotation. The client_template will be created in the next step.

Result:

A goniometer has been created.

Add the buttons and corresponding actions under the goniometer layer.

  "name": "buttonContainer",
  "dataKey": "buttonContainer",
  "type": "container",
  "constraints": [
    {
      "type": "pos",

          "params": {
            "layerName": "goniometer",
            "actions": [
              {
                "type": "reset"
              }
            ]
          }
        }
      ]
    },
    {
      "name": "calibrate",
      "dataKey": "calibrate",
      "type": "image",
      "value": "internal://check",
      "tint": "34a7c9",
      "scaleType": "scaleAspectFit",
      "constraints": [
        {
          "type": "pos",
          "anchor": "se",
          "relativeAnchor": "se",
          "x": "-5%",
          "y": "-5%"
        },
        {
          "type": "size",
          "width": "25%",
          "height": "150dp"
        }
      ],
      "actions": [
        {
          "type": "layerAction",
          "params": {
            "layerName": "goniometer",
            "actions": [
              {
                "type": "toggleGoniometer"
              }
            ]
          }
        }
      ]
    }
  ]
}

The buttons with toggleGoniometer and reset actions are created.

Result:

A goniometer layer with actions has been created.
