GUI/Maximum window dimensions
You are encouraged to solve this task according to the task description, using any language you may know.
The task is to determine the maximum height and width of a window that can fit within the physical display area of the screen without scrolling.
This is effectively the screen size (not the total desktop area, which could be bigger than the screen display area) in pixels minus any adjustments for window decorations and menubars.
The idea is to determine the physical display parameters for the maximum height and width of the usable display area in pixels (without scrolling).
The values calculated should represent the usable desktop area of a window maximized to fit the the screen.
- Considerations
- --- Multiple Monitors
For multiple monitors, the values calculated should represent the size of the usable display area on the monitor which is related to the task (i.e.: the monitor which would display a window if such instructions were given).
- --- Tiling Window Managers
For a tiling window manager, the values calculated should represent the maximum height and width of the display area of the maximum size a window can be created (without scrolling). This would typically be a full screen window (minus any areas occupied by desktop bars), unless the window manager has restrictions that prevents the creation of a full screen window, in which case the values represent the usable area of the desktop that occupies the maximum permissible window size (without scrolling).

EGL
To get the size of the window in a RuiHandler a JavaScript function is needed that is not natively supported by EGL. Therefore an external type is created to wrap the JavaScript function.
File 'Browser.js' in folder 'utils' in the WebContent folder of a rich UI project.
egl.defineClass(
'utils', 'Browser',
{
"getViewportWidth" : function () {
return window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
},
"getViewportHeight" : function(){
return window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;
}
});

In the graphics mode, Windows does it all automatically and displays a form that fills the entire area not obscured by the taskbar on your primary monitor:
#INCLUDE <Include\Windows.inc>
ShowWindow(ME, SW_MAXIMIZE)

Alternatively, one can obtain the unobscured area's dimensions using the following console script:
#APPTYPE CONSOLE
#INCLUDE <Include\Windows.inc>

Gambas
Overview
In gambas, the trick to determining the maximum window size that will fit on the screen is to create a form that is maximized and then query its dimensions from within a Form_Resize() event. Note that the form can be invisible during this process, and typically we would use the main modal window (FMain in this example).
Creating the form
From with the project create a form (FMain) with the following properties set:
FMain.Maximized = True
FMain.Visible = False ' The form can be invisible
From within the projectview, rightclick the FMain form and select Edit class from the contextmenu. This will display a form class file (FMain.class) as follows:
PUBLIC SUB _new()
END
PUBLIC SUB Form_Open()
END
Adding the form resize event
We can now add a Form_Resize() event to the class file with the necessary code to obtain the screen dimensions as follows:
PUBLIC SUB Form_Resize()
PRINT "The maximum window size that can be used without scrolling is "; FMain.Width; " x "; FMain.Height
END
Gambas
Public Sub Form_Open()
Print Desktop.Width
Print Desktop.Height
End
Output:
1920 1055

For this task, we can create a temporary window, and subtract its usable area from its size. This gives us the size (in pixels) used for decorations. Then we can query the screen size and subtract the size of those decorations.
For example:
(".wd 'qscreen') -&(2 3&{) (wd'pclose') ]-/".'qform',:&wd 'pc a; cc g isidraw; pshow; qchildxywh g'
1348 750
Here, we had a screen with 1366 by 768 pixels (width and height), and space for decorations subtract 18 from each of those dimensions.

Nim
With Gtk2
Getting the screen size, ignoring borders, is as easy as:
import
gtk2, gdk2
nim_init()
var w = gdk2.screen_width()
var h = gdk2.screen_height()
echo("WxH=",w,"x",h)
- Output:
WxH=1920x1080
But getting the real size excluding borders is more difficult, at least with Gtk. We need to draw a window at maximum size and wait enough time before asking for its size. The following program does the job:
import glib2, gtk2
proc printSize(window: PWindow): guint {.cdecl.} =
var width, height: gint
window.get_size(addr(width), addr(height))
echo "W x H = ", width, " x ", height
main_quit()
nim_init()
let window = window_new(WINDOW_TOPLEVEL)
window.maximize()
window.show_all()
discard g_timeout_add(100, printSize, addr(window[]))
main()
- Output:
W x H = 1920 x 1031
With Gtk3 (gintro)
This is the translation of Gtk2 program to Gtk3 using “gintro” bindings.
import gintro/[glib, gobject, gtk, gio]
var window: ApplicationWindow
#---------------------------------------------------------------------------------------------------
proc printSize(data: pointer): gboolean {.cdecl.} =
var width, height: int
window.getSize(width, height)
echo "W x H = ", width, " x ", height
window.destroy()
#---------------------------------------------------------------------------------------------------
proc activate(app: Application) =
## Activate the application.
window = app.newApplicationWindow()
window.maximize()
window.showAll()
discard timeoutAdd(PRIORITY_DEFAULT, 100, SourceFunc(printSize), nil, nil)
#———————————————————————————————————————————————————————————————————————————————————————————————————
let app = newApplication(Application, "Rosetta.ScreenSize")
discard app.connect("activate", activate)
discard app.run()

Raku
(formerly Perl 6)
This is kind-of a silly task. The maximum window size is going to depend on your OS, hardware, display server and graphics toolkit, not your programming language. Taken at face value, using a Linux system running an X11 display server, the maximum displayable window size is the resolution of your monitor. Basically, the size of your desktop viewport. The Raku module X11::libxdo returns the desktop viewport size for get-desktop-dimensions which is the effective maximum window size.
use X11::libxdo;
my $xdo = Xdo.new;
my ($dw, $dh) = $xdo.get-desktop-dimensions( 0 );
say "Desktop viewport dimensions: (maximum-fullscreen size) $dw x $dh";
- On my system returns:
Desktop viewport dimensions: (maximum-fullscreen size) 1920 x 1080
REXX
Most REXX interpreters essentially run "inside" a DOS window, and any attempts to find the (maximum) size of that
window is limited to that (current) window, not the maximum.
Furthermore, the maximum size would depend on the smallest font supported by that window, which is dependent
upon which code page is being used (and what font sizes it supports). On this author's system, it's a (fixed) font
size of 5 (which is barely readable, but it's useful for X,Y plotting or for cut─n─paste).
It should be noted that DOS doesn't support a window that extends to other monitors.

Run BASIC
Run Basic uses javaScript to return the width of the browser window. IE browser uses different functions than everyone else. So you write code for the world, and also for IE
html "<INPUT TYPE='HIDDEN' id='winHigh' name='winHigh' VALUE='";winHigh;"'></input>"
html "<INPUT TYPE='HIDDEN' id='winWide' name='winWide' VALUE='";winWide;"'></input>"
html "<script>
<!--
function winSize()
{
var myWide = 0, myHigh = 0;
if( typeof( window.innerWidth ) == 'number' ) {
//Non-IE
myWide = window.innerWidth;
myHigh = window.innerHeight;
} else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
//IE 6+ in 'standards compliant mode'
myWide = document.documentElement.clientWidth;
myHigh = document.documentElement.clientHeight;
} else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
//IE 4 compatible
myWide = document.body.clientWidth;
myHigh = document.body.clientHeight;
}
// window.alert( 'Width = ' + myWide + ' Height = ' + myHigh );
document.getElementById('winHigh').value = myHigh;
document.getElementById('winWide').value = myWide;
}
window.onresize = function()
{
var x = winSize();
}
var x = winSize();
//--></script>
"Scala
import java.awt.{Dimension, Insets, Toolkit}
import javax.swing.JFrame
class MaxWindowDims() extends JFrame {
val toolkit: Toolkit = Toolkit.getDefaultToolkit
val (insets0, screenSize) = (toolkit.getScreenInsets(getGraphicsConfiguration), toolkit.getScreenSize)
println("Physical screen size: " + screenSize)
System.out.println("Insets: " + insets0)

Sidef
Using the Tk library:
require('Tk')
func max_window_size() -> (Number, Number) {
%s'MainWindow'.new.maxsize;
}
var (width, height) = max_window_size();
say (width, 'x', height);
- Output:
1905x1050
Tcl
package require Tk
proc maxSize {} {
# Need a dummy window; max window can be changed by scripts
set top .__defaultMaxSize__
if {![winfo exists $top]} {
toplevel $top
wm withdraw $top
}
# Default max size of window is value we want
return [wm maxsize $top]
}
On this system, that returns 1440 836. Further discussion of related matters, including platform limitations, is on the Tcler's Wiki.
Visual Basic
Method 1
The first method involves querying the screen dimensions and then subtracting pixels used by the frame and desktop bars:
TYPE syswindowstru
screenheight AS INTEGER
screenwidth AS INTEGER
maxheight AS INTEGER
maxwidth AS INTEGER
END TYPE
DIM syswindow AS syswindowstru
' Determine the height and width of the screen
syswindow.screenwidth = Screen.Width / Screen.TwipsPerPixelX
syswindow.screenheight=Screen.Height / Screen.TwipsPerPixelY
' Make adjustments for window decorations and menubars
Method 2
The alternative method is to create a form that is maximized and then query its dimensions (similar to the method used in gambas).
Visual Basic .NET
Compiler: Roslyn Visual Basic (language version >= 14, e.g. with Visual Studio 2015)
(simple enough that it should probably work on every Framework version--.NET Core 3.0 will support Windows Forms on Windows only)
Must be referenced:
(managed interface) [System.Drawing] [System.Windows.Forms]Bounds are the screen's dimensions; working area is the is the region that excludes "taskbars, docked windows, and docked tool bars" (from Framework documentation).
Imports System.Drawing
Imports System.Windows.Forms
Module Program
Sub Main()
Dim bounds As Rectangle = Screen.PrimaryScreen.Bounds
Console.WriteLine($"Primary screen bounds: {bounds.Width}x{bounds.Height}")
Dim workingArea As Rectangle = Screen.PrimaryScreen.WorkingArea
Console.WriteLine($"Primary screen working area: {workingArea.Width}x{workingArea.Height}")
End Sub
End Module
- Output:
Primary screen bounds: 1714x1143 Primary screen working area: 1714x1103
Alternatively, use the dimensions of a borderless form with WindowState set to FormWindowState.Maximized (i.e. a full-screen window that is shown above the taskbar).
Imports System.Drawing
Imports System.Windows.Forms
Module Program
Sub Main()
Using f As New Form() With {
.WindowState = FormWindowState.Maximized,
.FormBorderStyle = FormBorderStyle.None
}
f.Show()
Console.WriteLine($"Size of maximized borderless form: {f.Width}x{f.Height}")
End Using
End Sub
End Module
- Output:
Size of maximized borderless form: 1714x1143

XPL0
GetFB is a built-in function available on the Raspberry Pi that returns information about the current frame buffer.
int A;
[A:= GetFB;
Text(0, "Width = "); IntOut(0, A(0)); CrLf(0);
Text(0, "Height = "); IntOut(0, A(1)); CrLf(0);
]- Output:
Width = 1280 Height = 720
