Extensions: INX widgets and parameters

Here you will find the different parameter elements you may use in your .inx files (Inkscape Extensions)

Introduction

Use parameter elements to capture user input for further use by a script. The basic structure of the element is:

<param name="some_name" type="some_type">default value</param>

The default value is the value that is shown in the input control the first time the user opens the dialog window. Inkscape automatically displays the values used last time when the dialog window is opened again.

Common attributes

type

Gives the type of parameter (int|float|string|boolean|enum|notebook|description|optiongroup|color).

name

Identifier of the parameter.

gui-text

Label of the parameter.

Not used by the notebook parameter (you can set the attribute, but it doesn't show in the dialog).

gui-description

Tooltip of the parameter.

gui-hidden

If true, hide the parameter in the GUI (default to false).

Types

Type	Code	Result
string	A textbox to capture a character string. <param name="some_name" type="string" _gui-text="Some text label">Some default text</param> To limit the number of characters the user is allowed to enter use the max_length attribute.
int	To get a textbox for an integer number. Limit the input range with the min and max attributes. By default, min=0 and max=10. <param name="some_name" type="int" min="1" max="100" _gui-text="Some label text">1</param>
float	To get a textbox for a float number. Limit the input range with the min and max attributes. To set the number of decimal places, use the precision attribute. By default, min=0, max=10, and precision=1 <param name="some_name" type="float" precision="3" min="0" max="9999" _gui-text="Some label text">1.234</param>
boolean	Gives a checkbox. Set the default value to true or 1, false or 0. <param name="some_name" type="boolean" _gui-text="Some label text">false</param>
enum	Creates a list of choices where the user can only select one option using a drop down select list. Create the different choices with <item> elements. The first item is selected by default. The returned value for the optiongroup element is the value attribute of the selected item. <param name="some_name" type="enum" _gui-text="Some label text"> <_item value="1">First option</_item> <_item value="2">Second option</_item> </param>
optiongroup	Creates a list of choices where the user can only select one option. By default this is displayed as radiobuttons. Set the attribute appearance="minimal" to display a drop down select list instead. <param name="some_name" type="optiongroup" _gui-text="Some label text"> <_option value="1">First option</_option> <_option value="2">Second option</_option> </param> Create the different choices with <option> elements. The first option is selected by default. The returned value for the optiongroup element is the value attribute of the selected option.
color	Creates a control to select a color. The returned value is a RGBA-value. <param name="some_name" type="color"></param>
description	To show some text in the dialog window, for example as "help" text. <param name="some_name" type="description">Some text here.</param> When additionally setting the attribute appearance="header" the text is styled as a heading. <param name="some_name" type="description" appearance="header">Header</param>
notebook	Creates a set of pages or tab-sheets. Create individual pages with the <page> element. The returned value for the notebook parameter element is the name of the selected page/tab. <param name="some_name" type="notebook"> <page name="name_page_1" _gui-text="First page"> <param>...</param> </page> <page name="name_page_2" _gui-text="Second page"> <param>...</param> </page> </param>
