问题描述

在FabricJs中使用FreeDrawing绘制某些东西之后，您可以选择绘制的内容并将其移动.有没有办法禁用此选择?

After you draw something with FreeDrawing in FabricJs, you are able to select what was drawn and move it. Is there a way to disable this selection?

推荐答案

如果画布上不需要任何交互性，则可以使用 StaticCanvas

In case you don't need any interactivity on your canvas, you can use StaticCanvas

var canvas = this.__canvas = new fabric.StaticCanvas('c');

或者，如果您只想禁用对特定对象(即最后的笔刷笔触)的选择，则可以在每次创建笔触时尝试调用以下代码:

Or, in case you want to disable selection only for specific objects, i.e. the last brush stroke, you can try calling the following code every time the stroke is created:

canvas.item(0).selectable = false;
canvas.renderAll();

如果您需要与其他对象进行交互，则还可以在画布初始化后立即定义

---

If you need interactivity for other objects, you can also define this right after canvas initialization

fabric.Object.prototype.selectable = false;

所有新对象都是不可选择的，除非您要创建可选择对象时另行指定

all new objects will be non-selectable, unless you specify otherwise when you want to create a selectable object

var text = new fabric.Text('Honey,\nI\'m subtle', {
    fontSize: 250,
    left: 50,
    top: 0,
    selectable: true // make this object selectable
});
canvas.add(text);
