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.

string

A textbox to capture a character string.

Example:

<param name="some_name" type="string" _gui-text="Some text label">Some default text</param>

int

To get a textbox for an integer number. Input to the textbox is limited to integer numbers with up and down buttons at the right-hand side.

Limit the input range with the min and max attributes.

Example:

<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. Input to the textbox is limited to numbers with up and down buttons at the right-hand side.

Limit the input range with the min and max attributes. To set the number of decimal places, use the precision attribute.

Example:

<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.

Example:

<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.

Example:

<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.

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.

Example:

<param name="some_name" type="optiongroup" appearance="minimal" _gui-text="Some label text">
   <_option value="1">First option</_option>
   <_option value="2">Second option</_option>
</param>

color

Creates a control to select a color.

The returned value is a RGBA-value.

Example: <param name="some_name" type="color"></param>

description

To show some text in the dialog window, for example as "help" text.

Example:

<param name="some_name" type="description"">Some text here.</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.

Example:

<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>
