In this article, we are going to see how to set the selectable property that is used to select the object for editing of a rectangle canvas using FabricJS. The canvas rectangle means rectangle is movable and can be stretched according to requirement. Further, the rectangle 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 rectangle. After this, we will initialize instances of Canvas and Rectangle provided by FabricJS and set the selectable of canvas rectangle to select the canvas object using selectable property and render the Rectangle on the Canvas as given in the below example.
Syntax:
fabric.Rect({
width: number,
height: number,
selectable: Boolean
});
Parameters: This function accepts three parameters as mentioned above and described below:
- width: It specifies the width of rectangle.
- height: It specifies the height of rectangle.
- selectable: It specifies that the object is selectable or not.
Example: This example uses FabricJS selectable property to create non-selectable object canvas rectangle.
