Output (on a 1280 x 800 screen with Windows XP):

<pre>Maximum dimensions of window : W 1280 x H 734

This is a modified example taken from the AutoHotkey documentation for the [http://ahkscript.org/docs/commands/SysGet.htm SysGet] command.

Also, the built in variables [http://ahkscript.org/docs/Variables.htm#Screen A_ScreenHeight] and [http://ahkscript.org/docs/Variables.htm#Screen A_ScreenWidth] contain the width and height of the primary monitor, in pixels.

. "`nRight:`t" MonitorRight " (" MonitorWorkAreaRight " work)"

. "`nBottom:`t" MonitorBottom " (" MonitorWorkAreaBottom " work)"

'''Output:'''

Because Axe is currently (6/22/2015) only available on the TI-83/84 black and white calculators, the screen dimensions are fixed at 96 by 64 pixels.

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:

ShowWindow(ME, SW_MAXIMIZE)

BEGIN EVENTS

 

Alternatively, one can obtain the unobscured area's dimensions using the following console script:

#INCLUDE <Include\Windows.inc>

 

PRINT "width = ", rc.Right - rc.Left, ", height = ", rc.Bottom - rc.Top

 

 

A typical output for a 1680x1050 primary monitor will be:

=== Overview ===

From with the project create a form (FMain) with the following properties set:

 

 

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:

 

 

END

PUBLIC SUB Form_Open()

 

 

=== 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:

 

PRINT "The maximum window size that can be used without scrolling is "; FMain.Width; " x "; FMain.Height

proc maxSize {} {

# Need a dummy window; max window can be changed by scripts

# Default max size of window is value we want

On this system, that returns <code>1440 836</code>. Further discussion of related matters, including platform limitations, is on [http://wiki.tcl.tk/10872 the Tcler's Wiki].

 

 

=== Method 1 ===

The first method involves querying the screen dimensions and then subtracting pixels used by the frame and desktop bars:

 

screenheight AS INTEGER

screenwidth AS INTEGER

syswindow.screenheight=Screen.Height / Screen.TwipsPerPixelY

 

 

=== 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).
