Scheme XML files.

Author

Paul D Turner

A Scheme file is a largely means to group other data files and resources together, and to define some of their interactions, and form a single point to load what might be considered a 'skin' for CEGUI's windows and widgets.

Scheme Element List:

<FalagardMapping> Element
<Font> Element
<GUIScheme> Element
<Imageset> Element
<ImagesetFromImage> Element
<LookNFeel> Element
<WindowAlias> Element
<WindowFactory> Element
<WindowRendererFactory> Element
<WindowRendererSet> Element
<WindowSet> Element

Overview

The reference for each element is arranged into sections, as described below:

• Purpose:
  • This section describes what the elements general purpose is within the specifications.
• Attributes:
  • This section describes available attributes for the elements, and whether they are required or optional.
• Usage:
  • Describes where the element may appear, whether the element may have sub-elements, and other important usage information.
• Examples:
  • For many elements, this section will contain brief examples showing the element used in context.

<GUIScheme> Element

• Purpose:
  • The <GUIScheme> element is the root element of the scheme file.
• Attributes:
  • version: specifies the version of the resource file. Should be specified for all files, current CEGUI scheme version is: 5
  • name: Specifies the name that the scheme will be known by within the system. Required attribute.
• Usage:
  • The <GUIScheme> element is the root element for scheme files.
  • The <GUIScheme> element may contain the following sub-elements (in any sequence):
    • Any number of <Imageset> elements.
    • Any number of <ImagesetFromImage> elements.
    • Any number of <Font> elements.
    • Any number of <LookNFeel> elements.
    • Any number of <WindowSet> elements.
    • Any number of <WindowRendererSet> elements.
    • Any number of <WindowAlias> elements.
    • Any number of <FalagardMapping> elements.
  • No element may contain a <GUIScheme> element as a sub-element.
• Examples:

<FalagardMapping> Element

• Purpose:
  • Specifies a mapping that ties together a concrete CEGUI::Window based object, a concrete CEGUI::WindowRenderer based object, and a WidgetLook definition to create a specified window type that can then be instantiated via the CEGUI::WindowManager.
• Attributes:
  • windowType: Specifies a name for the mapping / window type being created. Required attribute.
  • targetType: Specifies the name of the concrete CEGUI::Window based object that contains the logic for the window type being specified. Required attribute.
  • renderer: Specifies the name of the concrete CEGUI::WindowRenderer based object that contains the rendering specific code for the window type being specified. Required attribute.
  • lookNFeel: Specifies the name of the Falagard WidgetLook definition that contains imagery and other definitions for the window type being specified. Required attribute.
  • renderEffect: Specifies the name of a registered RenderEffect of which an instance will be created to be associated with each created window of WindowType. As the use of a RenderEffect requires an underlying RenderingWindow, if this is not automaticaly created by the TargetType, Renderer or LookNFeel the AutoRenderingSurface will be enabled prior to creating and assigning the RenderEffect. If the specified RenderEffect is not registered with the system when instantiation of TargetType is attempted, creation will not fail solely for lack of the effect - rather the window will be created with no effect set (the missing RenderEffect will be logged). Optional attribute.
• Usage:
  • The <FalagardMapping> element may only appear as a sub-element of the <GUIScheme> element.
  • The <FalagardMapping> element may not contain any sub-elements.
• Examples:

<Font> Element

• Purpose:
  • Specifies a Font to be loaded as part of the scheme. If a font with the requested name already exists, the file specified is not loaded.
• Attributes:
  • name: Specifies the name of the font as specified in the font xml file. This is a validation check; if this name is specified it must match the name given in the font xml file or an exception will be thrown. If this name is not given, the name is extracted from the font xml the first time it is loaded. Optional attibute.
  • filename: Specifies the path to the font XML file. Required attribute.
  • resourceGroup: Specifies the resource group identifier to pass to the ResourceProvider when loading the file specified in the Filename attribute. Optional attribute, if this is not specified the default resource group for Font files is used.
• Usage:
  • The <Font> element may only appear as a sub-element of the <GUIScheme> element.
  • The <Font> element may not contain any sub-elements.
• Examples:

<Imageset> Element

• Purpose:
  • Specifies an imageset to be loaded as part of this scheme. If an imageset with the requested name already exists, the file specified is not loaded.
• Attributes:
  • name: Specifies the name of the imageset as specified in the imagseset xml file. This is a validation check; if this name is specified it must match the name given in the imageset xml file or an exception will be thrown. If this name is not given, the name is extracted from the imageset the first time it is loaded. Optional attibute.
  • filename: Specifies the path to the imageset XML file. Required attribute.
  • resourceGroup: Specifies the resource group identifier to pass to the ResourceProvider when loading the file specified in the Filename attribute. Optional attribute, if this is not specified the default resource group for Imageset files is used.
• Usage:
  • The <Imageset> element may only appear as a sub-element of the <GUIScheme> element.
  • The <Imageset> element may not contain any sub-elements.
• Examples:

<ImagesetFromImage> Element

• Purpose:
  • Specifies an imageset to be created directly from an image file as part of this scheme. If an imageset with the requested name already exists, the file specified is not loaded.
• Attributes:
  • name: Specifies the name to be used for the imageset. If this attribute is not given, the imageset is given the name of it's file. Optional attibute.
  • filename: Specifies the path to the image file that will be loaded for this imageset (also used as the name of the Imageset if the Name attribute is not given). Required attribute.
  • resourceGroup: Specifies the resource group identifier to pass to the ResourceProvider when loading the file specified in the Filename attribute. Optional attribute, if this is not specified the default resource group for Imageset files is used.
• Usage:
  • The <ImagesetFromImage> element may only appear as a sub-element of the <GUIScheme> element.
  • The <ImagesetFromImage> element may not contain any sub-elements.
• Examples:

<LookNFeel> Element

• Purpose:
  • Specifies a LookNFeel file - containing WidgetLook definitions - to be parsed as part of this scheme.
• Attributes:
  • filename: Specifies the path to the looknfeel xml file that will be parsed. Required attribute.

• Usage:
  • The <LookNFeel> element may only appear as a sub-element of the <GUIScheme> element.
  • The <LookNFeel> element may not contain any sub-elements.
• Examples:

<WindowAlias> Element

• Purpose:
  • Specifies an alias for a given window type.
• Attributes:
  • alias: Specifies the name of the alias; this is an alternative name by which the window type specified by the Target attribute will be known.
  • target: Specifies the window type that will be created when a window of the type specified by the attribute Alias is specified.
• Usage:
  • The <WindowAlias> element may only appear as a sub-element of the <GUIScheme> element.
  • The <WindowAlias> element may not contain any sub-elements.

• Examples:

<WindowRendererSet> Element

• Purpose:
  • Specifies the name of a loadable module containing concrete CEGUI::WindowRenderer based entities and their factories. If one or more <WindowRendererFactory> elements are given, only the specified factories will be registered with the system; if no <WindowRendererFactory> elements are specified, all available factories from the module will be registered.
