Provider definition
Specifies the name and the Java class for the
provider. A provider is a template used to
generate content, which is displayed in the
channel.
Channel definition
Specifies the run time configuration of an
instance of the provider class. A channel is a unit
of content, often arranged in rows and columns.
You can also have channels of channels, called
container channels.
Provider and channel property definitions
Specify the values for provider and channel
properties. Properties defined in a provider
usually specify default values for the channels
that are derived from the provider. The display
configurations for the channels include
properties such as the title, description, channel
width, and so on. The properties defined in the
channel usually specify the specific value for that
channel that is different from the default value.
Container properties define the display
definition about how to display the contained
channels in the container, including: the layout
of the container (thin-wide, wide-thin, or
thin-wide-thin); a list of the contained channels;
the position of the channel (the row and column
number); and the window state of the contained
channels (minimized or detached).
The display profile exists only to provide property values for channels. It does not actually
define the overall layout or organization of what users see on their Desktops. However, the
display profile does indirectly control some aspects of channel presentation, such as column
layout for a table container or how the table container draws channels in a table.
The system reports errors when you try to save a display profile document containing invalid
XML. The error messages appear as a title, a message, and a sub-message. The title of the
message box is “Invalid XML document.” The message appears as one of the following:
■
■
■
■
Failed to parse XML...
Missing doctype in the XML
Failed to sore DP...
Invalid XML input...
If you receive an “Invalid XML document” error, you must correct the error to be able to save
the XML document.
