In this article, we are going to see how to disable the manipulation of a canvas Textbox using FabricJS. The canvas means the Textbox is movable and can be stretched according to requirement. Further, the Textbox can be customized when it comes to initial stroke color, fill color, stroke width, or radius.
Approach: To make it possible, we are going to use a JavaScript library called FabricJS. After importing the library using CDN, we will create a canvas block in the body tag which will contain our Textbox. After this, we will initialize instances of Canvas and Textbox provided by FabricJS and disable the manipulation of the Textbox using hasControls property and render the Textbox on the Canvas as given in the example below.
Syntax:
fabric.Textbox('text', {
hasControls: boolean
});
Parameters: This function accepts one parameter as mentioned above and described below:
- hasControls: It specifies whether to disable the controls or not.
Example: This example uses FabricJS to disable the manipulation of a canvas textbox. Note you have to click on the object to see the corners.
