Customizing Sigma Web Framework

This section discusses the customization features of the Sigma Framework, which enables you to change the look and feel of the program. This is an essential aspect of the Framework, mainly of interest to developers looking to adapt the system for OEM purposes or to conform with corporate website standards.

• Customizable HTML—Sigma includes header and footer files, and other HTML files, which can be modified and tailored to display headers and footers on each page, or display content affecting look and feel.
• Cascading style sheet (CSS)—The generic Sigma Framework header references a style sheet that can be used to change various CSS styles, including fonts and colors.
• Screen colors—Sigma permits modification of tab and screen colors, and includes other more obscure parameters that are useful for customizing the Sigma Framework appearance.
• Customizable install files—Sigma provides hooks into its install and uninstall dialogs, to permit users to customize these functions, especially useful in certain OEM applications.

These features and the application features combine to enable a high degree of customization. These customizable aspects of the Sigma Framework are introduced and discussed in the paragraphs that follow.

Additional notes

• Sigma Framework permits customization at various levels, including HTML files, style sheets, screen colors, and extension of the Install and Uninstall programs.
• Sigma can be repackaged with different screens. Existing screens can be re-arranged, disabled or deleted by simply re-arranging the contents of the "sigma-web" directory.
• The initial Sigma login screen can be selected by placing a custom executable or file as the first file in the "sigma-web" directory.
• The standard Sigma Framework application is quite simple and generic. The Framework is designed to express the look and feel required by a particular developer.
• Sigma Framework is an ideal candidate for OEM applications, since the customization permits repackaging of the system with large amounts of custom software, specific for a particular application.
