Color Picker Plugin

screenshot-edit.png Color picker for use in TWiki forms and TWiki applications


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.
An attribute of type="popup" shows a button that, when clicked, opens a color picker popup.
Text box width in number of characters Initial (default) color

Example form definition:

Name: Type: Size Values: Tooltip message: Attributes:
Background color color 12   Select color type="popup"

Note: The type="popup" attribute requires TWiki-6.0.2 or later.

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" }%
This will show an HTML input field named "text_color" and a color picker tied to it.

Parameter Description Default Example
name Name of input field (required) name="text_color"
value Initial color value, in hexadecimal notation for the combination of Red, Green, and Blue color values (RGB). (none) value="#0000ff"
size Size of input field, in number of characters (browser default) size="8"
class CSS class of input field or the rectangular color block (none) class="twikiInputField"
style Style of input field or the rectangular color block (none) style="width: 190px; height: 32px"
type Type of color widget:
"below" - color picker is located below the input field;
"popup" - pop-up a color picker window when clicking the button next to the input field
    (this uses very little vertical space);
"view" - a read-only rectangular block colored in the color value (no color picker);
"view-hex" - like view, in addition shows the color value as an RGB hexadecimal code (no color picker);
type="below" type="view-hex"
Additional parameters can be supplied; they will be added to the HTML input field or the rectangular color block.

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\"" }%
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)
