In-Depth Information
•
Text
: Text sections contain text that is easily formatted. Links to other con-
tent and images are embedded within the text by using very simple markup
syntax.
•
Navigation
: Navigation sections help you navigate through your hierarchy
of pages. Creating these sections requires very little thought or effort on
your part. You can also set up navigation within a long page by using sec-
tion navigation.
•
Data
: Data sections are used to display data in a row and column format
that is similar to a spreadsheet. There are two types of data sections: report
and data grid. A report is used to display read-only data from outside your
websheet. Data grids are spreadsheet-like objects that you build. You're
responsible for defining the columns, adding data-entry business rules,
providing default values, and so on. If you've used spreadsheets, you'll find
this work relatively easy to do.
•
Chart
: Chart sections are used to display graphs. Chart sections get their
data from data sections. You link a chart section to a data section by using
a simple intuitive wizard.
•
PL/SQL
: Users with PL/SQL knowledge can create PL/SQL sections and
write their own code against the associated schema. PL/SQL sections are
available only if the websheet application developer has enabled the Allow
SQL and PL/SQL attribute on the Websheet Properties page.
Navigation
We speak of websheet navigation in two contexts. First, we discuss navigating through
a websheet's content. Second, we discuss navigating through the pages that are used to
build a websheet. Be mindful that, in practice, you frequently flip back and forth
between these two contexts.
In both contexts, there are usually several ways to navigate to a given page or sec-
tion. The duplicate navigation choices might cause you a bit of confusion at first.
However, after you work with websheets for a while, the navigation choices become
helpful and intuitive. This chapter doesn't document every possible navigation path; in-
stead, it shows you where to look for navigation links so that you can quickly find a
comfortable navigation style that works for you.
