Available datatypes for XML contents

When creating XML contents, different data types can be used according to the requirements of the desired content. To each data type, a default widget is mapped which creates the input element (e.g. a text input field) for the form based XML content editor.

OpenCms provides the following data types for XML contents:

Data type Description Default widget
OpenCmsBoolean Used to store a boolean value like true or false. If not set, the default value returned is false. BooleanWidget
OpenCmsColor Used to store a color value in the hexadecimal HTML format #RRGGBB. ColorpickerWidget
OpenCmsDateTime Used to store a date/time information. DateTimeWidget
OpenCmsHtml Fields of this type provide the possibility to store text including HTML markup code formatting. HtmlWidget
OpenCmsLocale Stores Locale information, possible values are e.g. "en" or "de". StringWidget
OpenCmsString Stores short Strings which need no HTML formatting. StringWidget
OpenCmsVfsFile Stores links to other files in the VFS of OpenCms as absolute paths. VfsFileWidget

For each of the above described data types, a default widget is mapped. There are several other widgets available for usage in the XML content editor.

Editor widgets for the different data types

BooleanWidget Generates a check box input element to change the value of a boolean data type.
ColorpickerWidget Provides a text input field for manual input and a color picker popup to select the color with the mouse.
