Yahoo! Widgets

These programs are distributed in the hope that they will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Most are made available under the terms of the GNU General Public License as published by the Free Software Foundation, either version 2 of the License, or (at your option) any later version, but see the License conditions for each individual program.

Almost all of these programs are in the form of Yahoo! Widgets which require installation of the Yahoo! (Konfabulator) Widget Engine. Yahoo! Widgets are coded in XML and javascript.

They are packaged as zipped Widgets (with extension .widget) inside a zipped folder. The code can be examined by unzipping the .widget files.

Download figures are the final download counts at the close of the Yahoo! Widget Gallery.

N.B. The Widget Engine runs fully correctly on OS X versions up to and including 10.10.5 (Yosemite). It does not run fully correctly on OS X 10.11 (El Capitan), on macOS 10.12 (Sierra), on macOS 10.13 (High Sierra) or on macOS 10.14 (Mojave).
It does not run on macOS 10.15 (Catalina)

On Windows, the Widget Engine is known to run correctly on Windows XP and versions up to and including Windows 10.

On the later versions of macOS (10.11, 10.12, 10.13 and 10.14), almost all of the functions of the Widget Engine can be used successfully, if the Widget Dock is kept closed.
If the dock cannot be closed from the menubar, the Yahoo! Widgets preference file can be edited (while the Engine is not running) to set DockOpen to false, so that the dock does not open when the Widget Engine is started.
The preference file is normally at ~/Library/Preferences/com.yahoo.widgetengine.plist and can be edited using BBEdit, TextWrangler and Xcode.
The canvas context.drawImage(...) function no longer works. It is also not possible to run Widgets with an open debug window on El Capitan and Sierra.
Nevertheless, most/many Widgets can be used successfully.

Widget Vault - with Dean Beedell: Version 1.1.6

This Yahoo widget acts as a Widget 'AppStore' listing all the current widgets that are available from Dean Beedell and Harry Whitfield.

Wiring Calculator: This is a special purpose calculator which performs simple wiring calculations for copper wires used in low voltage circuits. Given three of the four quantities circuit length, current, wire cross section and voltage drop, the Widget calculates the value of the fourth.

WARNING: The calculator was designed to calculate the voltage drop in low voltage (12/24 volt) marine circuits where the voltage drop due to long wire circuits is more often a problem than the current carrying capacity of the wires. No attempt has been made to ensure that the results of any of the Widget's calculations conform to current electrical codes, such as the NEC or IEC codes. Users must check these and other safety matters for themselves.

The user can choose to work in SI units or USA units.
