%SHORTDESCRIPTION%

---++ Introduction

This TWiki plugin packages the [[http://acko.net/dev/farbtastic][Farbtastic color picker]], which is a jQuery plugin developed by Steven Wittens of Acko.net. The package adds a color picker to TWiki forms and TWiki applications.

---++ Using the color picker in !TWikiForms

This package adds a =color= type to %SYSTEMWEB%.TWikiForms:

| *Type* | *Description* | *Size* | *Value* |
| =color= | %IF{ "'%BASETOPIC%'!='%TOPIC%'" then="<img src='%PUBURLPATH%/%WEB%/ColorPickerPlugin/screenshot-small.png' alt='screenshot-small' width='150' height='170' align='right' /> " }%Single-line text box and a color picker to pick a color. The color can also be typed into the text box, such as =#123456=. %IF{ "'%BASETOPIC%'='TWikiForms'" then="[[ColorPickerPlugin][See details]]." }% | Text box width in number of characters | Initial (default) color |

Example form definition:

| *Name:* | *Type:* | *Size* | *Values:* | *Tooltip message:* |
| Background color | color | 12 | | Select color |

---++ Using the color picker in an HTML form

You can also use the color picker directly in your HTML forms, without having to write any code. Just include this in the topic text:
<verbatim>
<form action="...">
%COLORPICKER{ name="text_color" size="12" value="#123456" class="twikiInputField" }%
<form>
</verbatim>
This will show an HTML input field named "text_color" and a color picker tied to it.

%INCLUDE{ "VarCOLORPICKER" section="parameters" }%

Test: (this only works if the !ColorPickerPlugin is installed and enabled)

<form>
%COLORPICKER{ name="text_color" size="12" value="#123456" class="twikiInputField" }%
</form>

---++ Using the color picker with disabled plugin

It is also possible to use the color picker in HTML forms with _disabled_ !ColorPickerPlugin:

<verbatim>
%INCLUDE{ "%SYSTEMWEB%.ColorPickerPlugin" section="code" }%
<form action="...">
%INCLUDE{ "%SYSTEMWEB%.ColorPickerPlugin" section="picker" NAME="demo_color" SIZE="12" VALUE="#123456" EXTRA="class=\"twikiInputField\"" }%
</form>
</verbatim>
This will show an HTML input field named "demo_color" and a color picker tied to it. The ="code"= section should be included once per topic, the ="picker"= section can be included as many times as needed. The =NAME= parameter is required; =SIZE=, =VALUE= and =EXTRA= parameters are optional. Use the =EXTRA= parameter to add additional parameters to the HTML input field.

Test: (this works only if the !ColorPickerPlugin is installed and disabled)

<!--
%STARTSECTION{code}%<script type="text/javascript" src="%PUBURL%/%SYSTEMWEB%/ColorPickerPlugin/farbtastic.js"></script> <link rel="stylesheet" href="%PUBURL%/%SYSTEMWEB%/ColorPickerPlugin/farbtastic.css" type="text/css" />%ENDSECTION{code}%
%STARTSECTION{picker}%<input type="text" id="%NAME%" name="%NAME%" value="%IF{ "defined VALUE" then="$percntVALUE$percnt" else="#808080" }%" size="%IF{ "defined SIZE" then="$percntSIZE$percnt" else="12" }%" %IF{ "defined EXTRA" then="$percntEXTRA$percnt" }% /> <div id="%NAME%picker"></div> <script type="text/javascript"> $(document).ready(function() { $('#%NAME%picker').farbtastic('#%NAME%'); }); </script>%ENDSECTION{picker}%
-->
%INCLUDE{ "%TOPIC%" section="code" }%
<form>
%INCLUDE{ "%TOPIC%" section="picker" NAME="demo_color" SIZE="12" VALUE="#ff6611" EXTRA="class=\"twikiInputField\"" }%
</form>
