scala的鼠标事件有效吗?如何?

问题描述

我正在尝试在Scala中创建类似链接的标签.但是没有鼠标事件对我有用.他们应该如何工作?

I'm trying to create link-like label in scala. But no mouse events works for me. How are they supposed to work?

class Hyperlink extends Label{
text = "hyperlink"
reactions += {
    case MouseClicked(_,_,_,_,_) =>
        println("mouse clicked")}}

我将其放在某个面板中，然后像专业扫雷机一样单击标签...，控制台中没有任何显示.为什么?

I put this in some panel and click over the label like a pro minesweeper player... and nothing shows up in console. Why?

推荐答案

您需要listenTo相关内容，例如:

You need to listenTo the relevant thing, something like:

listenTo(this.mouse.clicks)

由于不推荐使用2.8.0鼠标，请改用鼠标

since 2.8.0 Mouse is deprecated, use mouse instead
