Fabric.js Textbox selectionBackgroundColor Property

Last Updated : 20 Jan, 2021

In this article, we are going to see how to change the selected background color of a canvas Textbox using FabricJS. The canvas Textbox means Textbox 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 FabricJS. 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 FabricJS and change the selected background color of the Textbox using selectionBackgroundColor property and render the Textbox on the Canvas as given in the example below.

Syntax:

fabric.Textbox('text', {
   selectionBackgroundColor: string
});

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

selectionBackgroundColor: It specifies the color of selection background.

Example: This example uses FabricJS to change selected background color of a canvas textbox. Note that you have to click on the object to see its selection background color.
