Create Textbox with Wait Cursor on Moving Objects using Fabric.js
In this article, we are going to create a Textbox with a wait cursor on moving objects using FabricJS. wait is one of the native cursor styles available which can be used in the FabricJS canvas too. FabricJS provides various types of cursors like default, all scroll, crosshair, col-resize, row-resize etc which are reusing the native cursor underhood. The moveCursor property sets the style of the cursor when the object is moved around in the canvas.
Syntax
new fabric.Textbox(text: String, { moveCursor: String }: Object)
Parameters
text This parameter accepts a String which is the text string that we want to display inside our textbox.
options (optional) This parameter is an Object which provides additional customizations to our textbox. Using this parameter colour, cursor, stroke width and a lot of other properties can be changed related to the object of which moveCursor is a property.
Options Keys
moveCursor This property accepts a String which allows us to set the default cursor value when moving this textbox object on the canvas. The value determines the type of the cursor to be used on moving the canvas object.
Example 1
Default cursor value when object is moved around the canvas
By default when we move around a textbox object in the canvas, the cursor type is move. Let’s see a code example to understand this.
<!DOCTYPE html>
<html>
<head>
<!-- Adding the Fabric JS Library-->
<script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/510/fabric.min.js"></script>
</head>
<body>
<h2>Default cursor value when object is moved around the canvas</h2>
<p>You can move around the textbox object around to see that the default cursor style is “move”</p>
<canvas id="canvas"></canvas>
<script>
// Initiate a canvas instance
var canvas = new fabric.Canvas("canvas");
canvas.setWidth(document.body.scrollWidth);
canvas.setHeight(250);
// Initiate a textbox object
var textbox = new fabric.Textbox("Add Sample Text Here", {
backgroundColor: "#fffff0",
width: 300,
left: 110,
top: 70,
fill: "#e1a95f",
strokeWidth: 2,
stroke: "#a40000",
textAlign: "center",
});
// Add it to the canvas
canvas.add(textbox);
</script>
</body>
</html>
Example 2
Passing the moveCursor property as key with a value
In this example, we are passing the moveCursor key to the textbox class with the value as “wait”. This will make sure that as we move around our object in the canvas, the cursor value is wait. This is illustrated in the code example below
<!DOCTYPE html>
<html>
<head>
<!-- Adding the Fabric JS Library-->
<script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/510/fabric.min.js"></script>
</head>
<body>
<h2>Passing the moveCursor property as key with a value</h2>

<canvas id="canvas"></canvas>
<script>
// Initiate a canvas instance
var canvas = new fabric.Canvas("canvas");
canvas.setWidth(document.body.scrollWidth);
canvas.setHeight(250);
// Initiate a textbox object
var textbox = new fabric.Textbox("Add Sample Text Here", {
backgroundColor: "#fffff0",
width: 300,
left: 110,
top: 70,
fill: "#e1a95f",
strokeWidth: 2,
stroke: "#a40000",
textAlign: "center",
moveCursor: "wait",
});
// Add it to the canvas
canvas.add(textbox);
</script>
</body>
</html>
