Color picker for use in TWiki forms and TWiki applications

Introduction

This TWiki plugin packages the 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 TWikiForms:

Type Description Size Value

color 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. Text box width in number of characters Initial (default) color

Type	Description	Size	Value
`color`	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`.	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

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:

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

This will show an HTML input field named "text_color" and a color picker tied to it. The size, value and class parameters are optional. Additional parameters can be supplied; they will be added to the HTML input field.

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

Using the color picker with disabled plugin

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

%INCLUDE{ "%SYSTEMWEB%.ColorPickerPlugin" section="code" }%
<form action="...">
%INCLUDE{ "%SYSTEMWEB%.ColorPickerPlugin" section="picker" NAME="demo_color" SIZE="12" VALUE="#123456" EXTRA="class=\"twikiInputField\"" }%
</form>

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)
