fabricjs对象/画布手动触发事件 [英] fabricjs object / canvas fire an event manually

问题描述

我想手动触发* 在画布事件上选择对象* -在对象区域中单击鼠标并选中对象时触发的同一事件-控件变为可见

i want to manually trigger *select object on the canvas event * - the same event that fires when a mouse click was made within an object area, and the object become selected - the controls become visible.

因此，换句话说，我想手动显示画布上指定对象的控件，而无需用户/鼠标交互.有帮助吗?

so in other words, i want to show controls for a specified object on the canvas MANUALLY, without user/mouse interaction. any help ?

推荐答案

解决方案.

如果有人在寻找答案-

fabric.Canvas.setActiveObject(fabric.Object) ...

如何找到解决方案: 我知道错误的想法是照顾'object:selected'之前的事件，但是没有这样的事件！所以我意识到我所要做的只是看'object:selected'的代码，这就是我发现哪个方法触发它的方法……在

how the solution was found: i understood that the wrong thinking was to look after the event that precedes the 'object:selected', but there is no such event !!! so i realized that all what i had to do is just look in the code for 'object:selected' and that's how i found which method fires it ... also it is well documented here, in docs .

建议:很高兴在文章中-getActiveObject / Group旁边注明.当前仅显示在此处- http://fabricjs.com/customization/

suggestion: would be great to note about it in the articles - next to getActiveObject / Group . currently it appears only here - http://fabricjs.com/customization/
