The Cwind Tcl extension written by Satoshi Imai was last updated to version 1.4 in 2003. It is surprising that the [original project is still accessible.

The original extension was compatible up to windows xp. It turned out to be very easy to port to a more modern version &ndash; specifically windows 7. The compilers used were the 32- and 64-bit gcc provided by the project. This repository contains:

+ the original (for posterity) source and binary zip files distributed by Satoshi Imai
+ updated source which compiles successfully using gcc version 6.3.0
+ a GNUmakefile which can be tailored for the compile
+ both 32- and 64-bit binaries

## New for Version 1.5 (August 2017)

New commands:<br>

+ getrect: Return a four-element list with the client rectangle for the active window
+ getwrect: Return a four-element list with the screen coordinates of the active window
+ dragl: Simulate a mouse drag with the left-button to a screen coordinate
+ dragm: Simulate a mouse drag with the middle-button to a screen coordinate
+ dragr: Simulate a mouse drag with the right-button to a screen coordinate
+ wdragl: Simulate a mouse drag with the left-button to a window coordinate
+ wdragm: Simulate a mouse drag with the middle-button to a window coordinate
+ wdragr: Simulate a mouse drag with the right-button to a window coordinate

Document previously undocumented commands:

+ top: Places the window at the top of the Z order.
+ bottom: Places the window at the bottom of the Z order.
+ topmost: Places the window above all non-topmost windows. The window maintains its topmost position even when it is deactivated.
+ notopmost: Places the window above all non-topmost windows (that is, behind all topmost windows).

## New for Version 1.5.1 (September 2017)

New command:<br>

+ version: Return a version string for Cwind.

Changes:

+ The drag functions seemed to be unreliable at times so they now do a drag
as a series of smaller moves. This seems to have fixed the problem.
