nw.js 如何禁止双击最大化？
如题：frame设置false后，用-webkit-app-region: drag;实现的拖动，但是如何禁止双击最大化
回复内容：
很多时候，我们觉得系统的Frame框很难看，于是想自定义。
自定义Frame的第一步是在package.config文件中将frame选项设置为false。
{
"name": "1",
"main": "index.html",
"nodejs": true,
"single-instance": false,
"chromium-args" : "--enable-webgl --ignore-gpu-blacklist",
"window": {
"show":true,
"title": "AxeSlide",
"toolbar": true,
"width":1000,
"height":400,
"resizable":true,
"show_in_taskbar":true,
"frame":false,
"kiosk":false,
"icon": "resources/img/axeslide.png",
"position":"center"
},
"webkit":{
"plugin":true
}
}
修改配置文件之后，我们看到的是下面的窗口。
无frame窗口是没有办法进行拖拽的，这肯定很不爽了，下面我们可以添加下面的样式到body上，实现整个窗口的拖动。
body {
-webkit-app-region: drag;
}
到此，我们的无边框窗体已经建成了，拖拽窗口的问题已经解决了，一切似乎完美了，就这么简单。不过当我们“手贱”地去双击下窗口的时候，窗口自动最大化了。其实这是nw.js优化过后的一个功能，在早期版本的时候，无边框窗口，双击是没有任何反应的，很多用户提了bug，作者于是添加了这个功能。但是不是任何时候，我们都需要最大化的，比如自定义了一个登录窗，我们想保持固定的大小怎么办？
我首先想到的是监听Click事件，如下：
document.onclick = function (e) {
e.preventDefault();
}
添加之后呢，然而并没有卵用，现在已经确认是nw.js的一个bug，据说在0.13版本修复了，不过还处于beta阶段。
一招不行，再来一招，可不可以通过设置最大，最小宽高都一样的方式解决呢？
继续修改配置文件。
此时我们再次测试，发现双击之后确实没有最大化了，不过窗口的位置却偏移到了屏幕的左上角。
这当然也不是我们需要的，那么就没办法处理了吗？既然默认的处理方式不行，自己动手丰衣足食吧，捕获Click和MouseMove事件，自己实现拖拽也不是很困难的，说干就干。先去掉原来用于body上执行拖拽的样式，然后添加下面的代码。
<script></script>
var gui = require('nw.gui')
var win = gui.Window.get()
var $win = window
var $nav = document.body;
var dragging = false
var mouse_x, mouse_y
var win_x, win_y;
$nav.onmousedown= function (e) {
e = e.originalEvent || e
var isbg = $(e.target).closest('.navbar-nav, #form-user').length
if (!isbg) return
dragging = true
mouse_x = e.screenX
mouse_y = e.screenY
win_x = win.x
win_y = win.y
};
$win.onmousemove=function (e) {
if (!dragging) return
win.x = win_x + (e.screenX - mouse_x)
win.y = win_y + (e.screenY - mouse_y)
};
$win.onmouseup=function () {
dragging = false
};
拖拽前窗口在左上角。
拖拽后。
ok，是不是完美的解决问题了呢？
