I loaded this listener in the created hook of the vue component:

($electron points to require ("electron"), which is a function of the vue-electron package)

created () {
    this.$electron.remote.getCurrentWindow.on("close", (e) => {
        e.preventDefault()
    }
}

according to the official document, e.preventDefault () will prevent the window from closing, but the window is still closed.

did not find the reason, what is the possible reason?

the project is built with electron-vue template and runs in development mode

• electron: 1.8.7
• vue: 2.5.13
• vue-router: 3.0.1
