推荐答案
此脚本将窗口移动到另一个屏幕的中心(如果有).
This script moves the window to the center of the other screen (if there is one).
var gui = require('nw.gui');
// initialize the Screen singleton
gui.Screen.Init();
// get the current window
var win = gui.Window.get();
function moveToOtherWindow() {
for(var i = 0; i < gui.Screen.screens.length; i++) {
var screen = gui.Screen.screens[i];
// check if the window is horizontally outside the bounds of this screen
if (win.x < screen.bounds.x || win.x > screen.bounds.x + screen.bounds.width) {
// move the window to this screen
win.x = screen.bounds.x + (screen.bounds.width - win.width) / 2;
win.y = screen.bounds.y + (screen.bounds.height - win.height) / 2;
break;
}
}
}
moveToOtherWindow();
