Task
Mouse position
You are encouraged to solve this task according to the task description, using any language you may know.

Get the current location of the mouse cursor relative to the active window. Please specify if the window may be externally created.

ActionScript

This shows the mouse position in a text field at the bottom-right corner and updates when the mouse is moved. <lang ActionScript3> package { 

   import flash.display.Sprite;
   import flash.events.Event;
   import flash.text.TextField;
   import flash.text.TextFieldAutoSize;
   import flash.text.TextFormat;

   public class MousePosition extends Sprite {
       
       private var _textField:TextField = new TextField();
       
       public function MousePosition() {
           if ( stage ) init();
           else addEventListener(Event.ADDED_TO_STAGE, init);
       }
       
       private function init(e:Event = null):void {
           removeEventListener(Event.ADDED_TO_STAGE, init);
           
           _textField.autoSize = TextFieldAutoSize.RIGHT;
           _textField.x = stage.stageWidth - 10;
           _textField.defaultTextFormat = new TextFormat(null, 15);
           _textField.text = "Mouse position: X = 0, Y = 0";
           _textField.y = stage.stageHeight - _textField.textHeight - 14;
           addChild(_textField);
           
           addEventListener(Event.ENTER_FRAME, _onEnterFrame);
       }
       
       private function _onEnterFrame(e:Event):void {
           _textField.text = "Mouse position: X = " + stage.mouseX + ", Y = " + stage.mouseY;
       }
       
   }

Ada

Library: GTK version GtkAda
Library: GtkAda
Library: GLib

The GTK procedure is Get_Pointer. It returns mouse coordinates relatively to a window (internally created). The following program shows a button, which when pressed indicates coordinates of the mouse pointer relatively to the main window: <lang Ada>with GLib; use GLib; with Gtk.Button; use Gtk.Button; with Gtk.Label; use Gtk.Label; with Gtk.Window; use Gtk.Window; with Gtk.Widget; use Gtk.Widget; with Gtk.Table; use Gtk.Table;

with Gtk.Handlers; with Gtk.Main;

procedure Tell_Mouse is 

  Window : Gtk_Window;
  Grid   : Gtk_Table;
  Button : Gtk_Button;
  Label  : Gtk_Label;

  package Handlers is new Gtk.Handlers.Callback (Gtk_Widget_Record);
  package Return_Handlers is
     new Gtk.Handlers.Return_Callback (Gtk_Widget_Record, Boolean);

  function Delete_Event (Widget : access Gtk_Widget_Record'Class)
     return Boolean is
  begin
     return False;
  end Delete_Event;

  procedure Destroy (Widget : access Gtk_Widget_Record'Class) is
  begin
     Gtk.Main.Main_Quit;
  end Destroy;

  procedure Clicked (Widget : access Gtk_Widget_Record'Class) is
     X, Y : GInt;
  begin
     Get_Pointer (Window, X, Y);
     Set_Text (Label, "At" & GInt'Image (X) & GInt'Image (Y));
  end Clicked;

begin 

  Gtk.Main.Init;
  Gtk.Window.Gtk_New (Window);
  Gtk_New (Grid, 1, 2, False);
  Add (Window, Grid);
  Gtk_New (Label);
  Attach (Grid, Label, 0, 1, 0, 1);
  Gtk_New (Button, "Click me");
  Attach (Grid, Button, 0, 1, 1, 2);
  Return_Handlers.Connect
  (  Window,
     "delete_event",
     Return_Handlers.To_Marshaller (Delete_Event'Access)
  );
  Handlers.Connect
  (  Window,
     "destroy",
     Handlers.To_Marshaller (Destroy'Access)
  );
  Handlers.Connect
  (  Button,
     "clicked",

  );
  Show_All (Grid);
  Show (Window);

AppleScript

The window can be any window on the system, externally created or otherwise, provided it can acquire focus. Mouse location is retrieved with help from AppleScriptObjC.

<lang AppleScript>use application "System Events"

property process : a reference to (first process whose frontmost = true) property window : a reference to front window of my process


set [Wx, Wy] to my window's position set [Cx, Cy] to {x, y} of the mouse's coordinates()


script mouse use framework "Foundation"

property this : a reference to current application property NSEvent : a reference to NSEvent of this property NSScreen : a reference to NSScreen of this

on coordinates() -- Screen dimensions set display to NSDeviceSize of deviceDescription() ¬ of item 1 of NSScreen's screens() as record

-- Mouse position relative to bottom-left of screen set mouseLoc to (NSEvent's mouseLocation as record) -- Flip mouse y-coordinate so it's relative to top of screen set mouseLoc's y to (display's height) - (mouseLoc's y)

mouseLoc end coordinates end script </lang>

Output:

<lang AppleScript>-- Cursor position relative to active window

[Cx - Wx as integer, Cy - Wy as integer]</lang>

AutoHotkey

c_sharp

Writes the absolute Mouse Position of the Screen into the Console <lang csharp> using System; using System.Windows.Forms; static class Program { 

   [STAThread]
   static void Main()
   {
       Console.WriteLine(Control.MousePosition.X);
       Console.WriteLine(Control.MousePosition.Y);
   }

} </lang>

Clojure

<lang lisp>(let [point (.. java.awt.MouseInfo getPointerInfo getLocation)] [(.getX point) (.getY point)])</lang>

Common Lisp

With the ltk library.

<lang lisp> (ql:quickload "ltk") (in-package :ltk-user) (defun motion (event) 

   (format t "~a x position is ~a~&" event (event-x event)))

(with-ltk () 

   ;; create a small window. Enter the mouse to see lots of events.
   (bind *tk* "<Motion>" #'motion))

</lang> This prints a lot of events of the form 


 #S(EVENT
  :X 0
  :Y 85
  :KEYCODE ??
  :CHAR ??
  :WIDTH ??
  :HEIGHT ??
  :ROOT-X 700
  :ROOT-Y 433
  :MOUSE-BUTTON ??)

The #S indicates we get a structure, so we can access the x position with (event-x event).

Delphi

Shows mouse-position on a label on the form.

<lang Delphi>procedure TForm1.FormMouseMove(Sender: TObject; Shift: TShiftState; X, 

 Y: Integer);

begin 

  lblMousePosition.Caption := ('X:' + IntToStr(X) + ', Y:' + IntToStr(Y));

end;</lang>


Delphi Console Program

The following program will help capture the mouse position with the help of Windows and classes units.

<lang Delphi>program Project1; {$APPTYPE CONSOLE} uses 

 SysUtils, Controls, Windows;

var 

 MyMouse : TMouse;

begin 

 MyMouse := TMouse.Create;
 While True do
 begin
   WriteLn('(X, y) = (' + inttostr(TPoint(MyMouse.CursorPos).x) + ',' + inttostr(TPoint(MyMouse.CursorPos).y) + ')');
   sleep(300);
 end

end.</lang>

EasyLang

Run it

<lang>on mouse_move 

 clear
 text mouse_x & " " & mouse_y

.</lang>

EchoLisp

When the plot library is loaded, the mouse position - relative to the plotting area coordinates, is displayed inside the info panel. <lang lisp> (lib 'plot) (plot-x-minmax 10) ; set logical dimensions of plotting area (plot-y-minmax 100) 

 → (("x" 0 10) ("y" 0 100))
press ESC to see the canvas
the mouse position is displayed as , for example, [ x
5.6 y : 88.7]
0 <= x <= 10, 0 <= y <= 100

Emacs Lisp

For Emacs' own frames (which is what Emacs calls its window system windows), the frame the mouse is over and where the mouse is within that frame can be obtained with

<lang Lisp>(mouse-pixel-position) => (FRAME . (X . Y))</lang>

Or mouse-position for characters instead of pixels. Works when the mouse is over any Emacs frame, not just when that frame is the active focused window.

There's no particularly easy way to inquire about a non-Emacs focused window, only generic X11 or similar approaches run externally.

F#

Have to do a lot of interop here. Primarily because the active window may not be a .NET form/control. If the question was for the point relative to the current window, life would be much simpler. <lang fsharp>open System.Windows.Forms open System.Runtime.InteropServices

Gambas

In gambas, the position of the pointer can only be determined when the click button is held down. A window with a drawing area is required, because this is the only widget that can track pointer movement within gambas.

Go

Library: RobotGo


The active window may be externally created. <lang go>package main

import ( 

   "fmt"
   "github.com/go-vgo/robotgo"

)

func isInside(x, y, w, h, mx, my int) bool { 

   rx := x + w - 1
   ry := y + h - 1
   return mx >= x && mx <= rx && my >= y && my <= ry

}

func main() { 

   name := "gedit" // say
   fpid, err := robotgo.FindIds(name)
   if err == nil && len(fpid) > 0 {
       pid := fpid[0]
       robotgo.ActivePID(pid) // make gedit active window
       x, y, w, h := robotgo.GetBounds(pid)
       fmt.Printf("The active window's top left corner is at (%d, %d)\n", x, y)
       fmt.Printf("Its width is %d and its height is %d\n", w, h)
       mx, my := robotgo.GetMousePos()
       fmt.Printf("The screen location of the mouse cursor is (%d, %d)\n", mx, my)
       if !isInside(x, y, w, h, mx, my) {
           fmt.Println("The mouse cursor is outside the active window")
       } else {
           wx := mx - x
           wy := my - y
           fmt.Printf("The window location of the mouse cursor is (%d, %d)\n", wx, wy)
       }
   } else {
       fmt.Println("Problem when finding PID(s) of", name)
   }

}</lang>

Output:

A first run after placing mouse cursor inside active window: 

The active window's top left corner is at (547, 167)
Its width is 792 and its height is 506
The screen location of the mouse cursor is (949, 446)
The window location of the mouse cursor is (402, 279)

A second run after moving mouse cursor outside active window: 

The active window's top left corner is at (547, 167)
Its width is 792 and its height is 506
The screen location of the mouse cursor is (334, 639)
The mouse cursor is outside the active window

Groovy

Based on Java solution: <lang groovy>1.upto(5) { 

   Thread.sleep(1000)
   def p = java.awt.MouseInfo.pointerInfo.location
   println "${it}: x=${p.@x} y=${p.@y}"

}</lang>

Sample output: 

1: x=857 y=0
2: x=765 y=447
3: x=0 y=535
4: x=715 y=283
5: x=1335 y=83

HicEst

Mouse click positions for windows created internally. X and Y are in units of current xy axes (optional: invisible). <lang hicest> WINDOW(WINdowhandle=handle) 

  AXIS(WINdowhandle=handle, MouSeCall=Mouse_Callback, MouSeX=X, MouSeY=Y) 
END

SUBROUTINE Mouse_Callback() 

  WRITE(Messagebox, Name) X, Y
END</lang>

Icon and Unicon

In Icon/Unicon the mouse position may be tracked between button presses for any window created by the program. The following code snippet taken from the Icon Graphics Book on page 197-198 shows how to track the mouse. <lang Icon>until *Pending() > 0 & Event() == "q" do { # loop until there is something to do 

  px := WAttrib("pointerx")
  py := WAttrib("pointery")
  #  do whatever is needed
  WDelay(5)  # wait and share processor
  }

</lang>

Java

Works with: Java version 1.5+

The mouse position can be checked at any time by calling <lang java5>Point mouseLocation = MouseInfo.getPointerInfo().getLocation();</lang> This returns a point on the entire screen, rather than relative to a particular window. This call can be combined with getLocation() from any Component (including a Frame, which is a window) to get the location relative to that Component.

JavaScript

In a browser environment, it's impossible to actually get the cursor position at the specific moment. You must wait for user input (movement, click, etc). One of many ways to add an event listener:

<lang javascript>document.addEventListener('mousemove', function(e){ 

 var position = { x: e.clientX, y: e.clientY }

}</lang>

In the above example, the window may not be external. It must in fact be a web browser window, which runs the script.

Julia

<lang julia>using Gtk

const win = GtkWindow("Get Mouse Position", 600, 800) const butn = GtkButton("Click Me Somewhere") push!(win, butn)

callback(b, evt) = set_gtk_property!(win, :title, "Mouse Position: X is $(evt.x), Y is $(evt.y)") signal_connect(callback, butn, "button-press-event")

showall(win)

c = Condition() endit(w) = notify(c) signal_connect(endit, win, :destroy) wait(c) </lang>

Kotlin

Translation of: Groovy

fun main(args: Array<String>) { 

   (1..5).forEach {
       Thread.sleep(1000)

       println("${it}: x = ${"%-4d".format(p.x)} y = ${"%-4d".format(p.y)}")
   }

}</lang> Sample output:

2: x = 1112 y = 478
3: x = 1331 y = 511
4: x = 269  y = 562
5: x = 247  y = 505

Perl

Library: Perl/SDL

The following code will use the SDL module, a wrapper for the libSDL C-library. When you move the mouse over the created window, the mouse position get printed and the program terminates. <lang Perl>use SDL; use SDL::Events; use SDLx::App;

my $app = SDLx::App->new; $app->add_event_handler( sub { my $event = shift; if( $event->type == SDL_MOUSEMOTION ) { printf( "x=%d y=%d\n", $event->motion_x, $event->motion_y ); $app->stop } } ); $app->run; </lang>

Output:
x=15 y=304

Phix

The following example shows three labels being updated with the mouse position.
The globalmotion label is updated whenever the mouse moves anywhere within the window, but not outside it.
The canvasmotion label is updated whenever the mouse moves within the canvas, but not elsewhere in the window (or beyond).
The timer label is updated every three seconds and gets mouse positions anywhere on the whole screen, whether it moves or not.
Note that canvasmotion coordinates are relative to the top left of the canvas, whereas the other two are absolute.

Tcl

Library: Tk

<lang tcl>package require Tk 8.5 set curWindow [lindex [wm stackorder .] end]

  1. Everything below will work with anything from Tk 8.0 onwards

set x [expr {[winfo pointerx .] - [winfo rootx $curWindow]}] set y [expr {[winfo pointery .] - [winfo rooty $curWindow]}] tk_messageBox -message "the mouse is at ($x,$y) in window $curWindow"</lang>

Visual Basic

There are two methods for determining where the mouse pointer is. The first only works when the pointer is actually over the window containing the code. This actually works for any control that has a MouseMove event, but it doesn't work if the pointer is over anything else, including controls on the form (so if the pointer is over a button on the current form, the event will only fire for the button, not the form). <lang vb>Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) 

   'X and Y are in "twips" -- 15 twips per pixel
   Me.Print "X:" & X
   Me.Print "Y:" & Y

End Sub</lang>

The second method uses the Windows API, and can be easily translated to any language that can make API calls. This example uses a Timer control to check the mouse position. <lang vb>Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long

Private Type POINTAPI 

   'X and Y are in pixels, with (0,0) being the top left corner of the primary display
   X As Long
   Y As Long

End Type

Private Pt As POINTAPI

Private Sub Timer1_Timer() 

   GetCursorPos Pt
   Me.Cls
   Me.Print "X:" & Pt.X
   Me.Print "Y:" & Pt.Y

End Sub</lang>

XPL0

GetMousePosition(0) = X coordinate; 1 = Y coordinate. For video modes $0..$E and $13 the maximum coordinates are 639x199, minus the size of the pointer. For modes $F..$12 the coordinates are the same as the pixels. VESA graphic modes are (usually) 639x479 regardless of the resolution. For 80-column text modes divide the mouse coordinates by 8 to get the character cursor position.

The mouse cursor location is always relative to the upper-left corner of the screen. A window may be externally created ... using a fair amount of code because the version of XPL0 used with these Rosetta Code examples does not make Windows applications (however see "Simple windowed application").

<lang XPL0>include c:\cxpl\stdlib; if not OpenMouse then Text(0, "A mouse is required") else [ShowMouse(true); 

     IntOut(0, GetMousePosition(0));  ChOut(0, ^,);
     IntOut(0, GetMousePosition(1));  CrLf(0);
    ]</lang>
