     Form newForm = new Form();
     newForm.Text = "It's a new Window!";

E

Java AWT/Swing

Implementation: E-on-Java

when (currentVat.morphInto("awt")) -> {
    def w := <swing:makeJFrame>("Window")
    w.setContentPane(<swing:makeJLabel>("Contents"))
    w.pack()
    w.show()
}

IDL

With some example values filled in:

Id = WIDGET_BASE(TITLE='Window Title',xsize=200,ysize=100)
WIDGET_CONTROL, /REALIZE, id

Java

Library: Swing

   import javax.swing.JFrame;
   import javax.swing.WindowConstants;
   
   public class SimpleWindow {
   
   	public static void main(String[] args) {
   
   		JFrame window = new JFrame("This is a title!");
   		
   		window.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
   		window.setSize(800, 600);
   		window.setVisible(true);
   	}
   
   }

JavaScript

   window.open("webpage.html", "windowname", "width=800,height=600");

mIRC Scripting Language

Interpreter: mIRC

Switches: C = Center Window p = Picture Window d = Desktop Window

alias CreateMyWindow {
 .window -Cp +d @WindowName 600 480
}

Perl

Interpreter: Perl 5.8.8

Using Tk:

 use Tk;
 
 $mw = MainWindow->new();
 MainLoop;

Python

Interpreter: Python 2.4, 2.5

Tkinter

 import Tkinter
 
 w = tkinter.Tk()
 w.mainloop()

wxPython

 from wxPython.wx import *
 
 class MyApp(wxApp):
   def OnInit(self):
     frame = wxFrame(NULL, -1, "Hello from wxPython")
     frame.Show(true)
     self.SetTopWindow(frame)
     return true
 
 app = MyApp(0)
 app.MainLoop()

Pythonwin

 import win32ui
 from pywin.mfc.dialog import Dialog
 
 d = Dialog(win32ui.IDD_SIMPLE_INPUT)
 d.CreateWindow()

PyGTK

 import gtk
 
 window = gtk.Window()
 window.show()
 gtk.main()

Ruby

Interpreter: Ruby 1.8.5

Tk

require 'tk'

window = TkRoot::new()
window::mainloop()

GTK

require 'gtk2'

window = Gtk::Window.new.show
Gtk.main

RapidQ

  create form as qform
     center
     width=500
     height=400
  end create
  form.showModal

Tcl

Loading the "Tk" package is all that is required to get an initial window:

  package require Tk

If you need an additional window:

  toplevel .top

If you are using the increasingly popular tclkit under MS Windows, all you have to do is associate the tcklkit with the extension ".tcl" and then create an empty file with the name (e.g.) nothing.tcl. Douple-clicking that will "open a window" (an empty one).

Toka

Library: SDL

Toka does not inherently know about graphical environments, but can interact with them using external libraries. This example makes use of the SDL library bindings included with Toka.

 needs sdl
 needs case

 sdl_event_size malloc is-data event
 800 600 sdl_setup drop

 #! Process events, exiting when the window is closed
 [
   event SDL_WaitEvent drop

   event sdl_event_type switch    
   SDL_QUIT [ bye ] case

   TRUE
 ] keep whileTrue

Visual Basic .NET

Framework: .NET

   Dim newForm as new Form
   newForm.Text = "It's a new window"
  
       newForm.Show()
