Get XWindow ID of a GTK WIndow

immjs commented 2 years ago

Hello, How can I get the XWindow ID of a GTK window? I can only seem to find information about getting the XWindow ID of a GDK window.

On Linux like suggested here https://stackoverflow.com/questions/14732838/how-to-get-xwindow-id-in-gtk3

const gi = require('node-gtk')
const Gtk = gi.require('Gtk', '3.0')
// Importing 'GdkX11' adds .getXid()
gi.require('GdkX11')

gi.startLoop()
Gtk.init()

const win = new Gtk.Window({title: 'Hello', window_position: Gtk.WindowPosition.CENTER})
win.on('show', () => {
    const xid = win.getWindow().getXid();
    console.log(`xid: 0x${Number(xid).toString(16)}`)
    Gtk.main()
})
win.on('destroy', Gtk.mainQuit)
win.showAll()

$ node index.js 
xid: 0x6200003

$ xwininfo -name Hello

xwininfo: Window id: 0x6200003 "Hello"
