Fabric.js Textbox lockMovementX Property

  • Last Updated : 22 Jan, 2021

In this article, we are going to see how to lock the horizontal movement of the canvas Textbox using Fabric.js. The Textbox in Fabric.js is movable and can be stretched according to requirement. Further, the Textbox can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.

To make it possible, we are going to use a JavaScript library called Fabric.js. After importing the library, we will create a canvas block in the body tag which will contain the Textbox. After this, we will initialize instances of Canvas and Textbox provided by Fabric.js, lock the horizontal movement of the canvas Textbox using lockMovementX property and render the Textbox on the Canvas as given in the below example.

Syntax:

fabric.Textbox('text', {
   lockMovementX: boolean
});

Parameters: This function accepts a single parameter as mentioned above and described below:

  • lockMovementX: It specifies whether to lock horizontal movement of canvas.

Example: This example uses Fabric.js to lock the horizontal movement of the Textbox as given below.

        var text = new fabric.Textbox(
            'A Computer Science Portal', {
            width: 500,
            lockMovementX: true
        });
  
        // Render the Textbox in canvas 
        canvas.add(text);
        canvas.centerObject(text);
    </script>
