Question

我需要将光标类型更改为＆＃34;手写＆＃34;在悬停形状...

var canvas = window._canvas = new fabric.Canvas('ImgCanvas');
function changeCursor(cursorType) {
canvas.defaultCursor = "Handwriting";
}

我试过这个但没有工作

Answer 1

Surendhar，

要将光标更改为您需要定义为的形状：

canvas.hoverCursor = 'cursor type'

这是游标的list

如果您需要自定义光标，则必须使用自定义光标在结构画布上创建 div 元素。当你有'mouseover'事件时，刚刚指定的形状为canvas.hoverCursor ='none'，并显示自定义的一个。

您可以查看fiddle这是自定义光标的简单示例。您必须重新访问此代码才能在不刷新自定义光标的情况下工作。这是关于自定义光标的鼠标悬停事件。您必须禁用自定义光标的每个 div 元素的鼠标悬停事件。

您可以将hoverCursor直接更改为单个形状，也可以全局更改为整个画布。看看下面的片段。

＆＃13;

var canvas = this.__canvas = new fabric.Canvas('c');
// pointer for all
canvas.hoverCursor = 'pointer';

var rect = new fabric.Rect({
  left: 50,
  top: 30,
  width: 100,
  height: 100,
  fill: 'green',
  angle: 20,
});
var rect2 = new fabric.Rect({
  left: 180,
  top: 30,
  width: 100,
  height: 100,
  fill: 'green',
  angle: 20,
});
canvas.add(rect);
canvas.add(rect2);
canvas.renderAll();

var canvas2 = this.__canvas = new fabric.Canvas('c2');
var rect = new fabric.Rect({
  left: 120,
  top: 30,
  width: 100,
  height: 100,
  fill: 'green',
  angle: 20,
  // pointer for the selected shape
  hoverCursor: "pointer"
});
canvas2.add(rect);
canvas2.renderAll();

要更改fabric.js对象的光标，可以将hoverCursor或moveCursor设置为您自己的图像。例如：

object.set({hoverCursor: 'url("https://s3-us-west-2.amazonaws.com/s.cdpn.io/9632/happy.png"), auto'});
