Shelf configuration file format shelf tool

On this page

Note

It is much easier to edit the shelf in Houdini. However, in a large site it may be useful at times to batch edit/replace shelf files directly.

Overview

Houdini loads any files with a .shelf extension in the path specified by the TOOLBAR_PATH environment variable. By default this is HOUDINI_PATH/toolbar, so for example you can override the "factory" files in $HFS/houdini/toolbar using files in $HOME/houdiniX.x/toolbar.

Shelf configuration files are in XML format. See below for information about each tag. There is also an XSD schema file, $HFS/houdini/toolbar/shelf.xsd, you can use to validate your own XML shelf definition files.

Tags

<shelfDocument>

This is the top-level element for a shelf configuration file. This element can contain any number of shelfSet, toolshelf, and/or tool elements.

<shelfSet>

Defines a set of shelf tabs the user can load as a group. Contains memberToolshelf elements.

name attribute

The internal name of the set. If a file later in the path has a set with the same name, it will replace this one.

label attribute

The human-readable label for the set in the user interface.

You can optionally add a <readOnly/> sub-element to prevent users from editing the tab set in Houdini.

<memberToolshelf>

(zero or more sub-elements of shelfSet) Specifies a shelf tab as part of a set.

name attribute

The name of a shelf tab defined by a toolshelf. The named tab can be in this file or any other shelf configuration file on the path.

<toolshelf>

Defines the tools on a shelf tab. Contains memberTool elements.

name attribute

The internal name of the shelf tab. If a file later in the path has a tab with the same name, it will replace this one.

label attribute

The human-readable label for the tab in the user interface.

You can optionally add a <readOnly/> sub-element to prevent users from editing the shelf tab in Houdini.

<memberTool>

(zero or more sub-elements of toolshelf) Specifies a tool as part of a shelf tab.

name attribute

The name of a tool defined by a tool element. The named tool can be in this file or any other shelf configuration file on the path.

<tool>

Defines a shelf tool.

name attribute

The internal name of the tool. If a file later in the path has a tool with the same name, it will replace this one.

label attribute

The human-readable label for the tool in the user interface.

icon attribute

(optional) The path to an image file (or an internal Houdini icon reference such as SOP_copy).

This element must have a script sub-element specifying the script to run when the user clicks the tool.

You can optionally add a <readOnly/> sub-element to prevent users from editing the tool in Houdini.

If you don’t specify any contextNetType or contextOpType elements inside a toolMenuContext element inside the tool, the tool will not appear on any ⇥ Tab menu.

<script>

(required sub-element of tool) A Python script or HScript to run when the user clicks the tool.

It’s usually a good idea to wrap the script in a CDATA tag to prevent <, >, and & characters in the script from causing XML errors.

scriptType attribute

Either python or hscript.

<shelfDocument>
    <tool name="sample_tool" label="Sample Tool" icon="PLASMA_App">
        <script scriptType="python"><![CDATA[

        hou.ui.displayMessage("Hello world!")

        ]]></script>
    </tool>
</shelfDocument>

<helpText>

(optional sub-element of tool) Wiki-formatted or HTML help to display in the browser when the user asks for help for the tool. This will be overridden by the helpURL tag.

It’s usually a good idea to wrap the help text in a CDATA tag to prevent <, >, and & characters in the help from causing XML errors.

<helpText>

(optional sub-element of tool) Wiki-formatted or HTML help to display in the browser when the user asks for help for the tool. This will be overridden by the helpURL tag.

It’s usually a good idea to wrap the help text in a CDATA tag to prevent <, >, and & characters in the help from causing XML errors.

<helpURL>

(optional sub-element of tool) A URL to load in the browser when the user asks for help for the tool. If both helpURL and helpText are present and not empty, Houdini uses the helpURL.

<toolSubmenu>

(optional sub-element of tool) A list of menu labels, separated by / characters, specifying which sub-menu of the ⇥ Tab menu the tool will appear in.

For example, if <toolSubmenu>My Tools/Shaping</toolSubmenu> will make the tool appear in a My Tools ▸ Shaping submenu on the ⇥ Tab menu.

<shelfDocument>
    <tool name="sample_tool" label="Sample Tool" icon="PLASMA_App">
        <script scriptType="python">...</script>
        <toolSubmenu>Fee/Fi/Fo/Fum</toolSubmenu>
        <toolMenuContext name="network">
                <contextNetType>OBJ</contextNetType>
        </toolMenuContext>
    </tool>
</shelfDocument>

  • Note that the tool must also have a toolMenuContext if you want the tool to appear in the ⇥ Tab menu.

  • The label matching is case-sensitive.

  • Sub-menus that do not exist will be created.

<toolMenuContext>

(zero or more sub-elements of tool) Specifies in which contexts this tool should appear in the ⇥ Tab menu.

name attribute

Which pane type whose ⇥ Tab menu the tool will appear in. Valid values are viewer (user presses ⇥ Tab in the viewer), network (user presses ⇥ Tab in the network editor), pop_viewer (the viewer when viewing a particle network), or cop_viewer (the viewer when viewing a compositing network).

Note that you need separate toolMenuContext elements for each pane type (specified by the name attribute) you want the tool to appear in. For example, if you want the tool to appear in the ⇥ Tab menu in both the 3D viewer and the network editor, you need a <toolMenuContext name="viewer"> element and a <toolMenuContext name="network"> element.

<contextNetType>

(zero or more sub-elements of toolMenuContext) The tool appears in the ⇥ Tab menu only in networks of this type. You can specify multiple contextNetType elements to have the tool appear in multiple network types.

The text of this element is a network type. Acceptable values are OBJ (the scene level), SOP (a geometry network), POP (particle network), DOP (dynamics network), CHOP, ROP (render network), SHOP (material network), COP2 (compositing network), VOP, or VOPNET.

For example, to make the tool appear in the network editor’s ⇥ Tab menu, but only when viewing an object, geometry, or particle network:

<toolMenuContext name="network">
    <contextNetType>OBJ</contextNetType>
    <contextNetType>SOP</contextNetType>
    <contextNetType>POP</contextNetType>
</toolMenuContext>

<contextOpType>

(zero or more sub-elements of toolMenuContext) If you specify this as a sub-element of toolMenuContext, the tool will only appear in the ⇥ Tab menu in networks where it is valid to create a node of this type.

The text of this element is a node specification, such as Object/geo or Sop/copy.

contextOpType overrides contextNetType if you specify both. In the example below, the tool would not appear in the ⇥ Tab menu in a geometry (SOP) network, because even though the contextNetType matches, the contextOpType does not match.

<toolMenuContext name="network">
    <contextOpType>Object/my_asset</contextOpType>
    <contextNetType>OBJ</contextNetType>
    <contextNetType>SOP</contextNetType>
    <contextNetType>POP</contextNetType>
</toolMenuContext>

<readOnly>

You can add this as an empty element to a shelfSet, toolshelf, or tool element to prevent users from editing the tab set. 

<?xml version="1.0" encoding="utf-8" ?>
<shelfDocument>
    <tool name="scribble" label="Scribble">
        <readOnly/>
        <script scriptType="python">
        ...
        </script>
    </tool>
</shelfDocument>

Changing the default shelf tabs

Shelf sets, shelves, and tools from files later in the path will replace earlier definitions by the element’s name attribute. The file name of the shelf configuration file makes no different.

You can only replace a default shelf tab (by specifying a shelf tab with the same name in a user configuration file). It’s not possible specify that certain tools should be added or removed from a default shelf tab.

To modify one of the default shelf tabs:

  1. Find the default shelf file containing the <toolshelf> element defining the tab, either in $HFS/houdini/toolbar/ShelfDefinitions.shelf or $HFS/houdini/toolbar/ShelfDefinitions.master_shelf. Open the file in a text editor.

  2. Select the <toolshelf> element defining the shelf tab and copy it to the clipboard.

  3. Start a new file, fill in the XML declaration and the <shelfDocument> element, and paste in the copied <toolshelf> element.

  4. Remove or add <memberTool> elements to change which tools are on the shelf tab.

  5. Save the file somewhere in the Houdini toolbar path, for example $HOME/houdiniX.x/toolbar/mytools.shelf.
