Page
Zero
Page Zero is a special application page that must
be deliberately created by the developer. It is not created by
default when using the Create Application wizards.
The intended purpose of Page Zero is that any
items created on Page Zero will be rendered on every other page of the
application. The only restriction is Page Zero will only render the
following types of components:
An example use for Page Zero would be for a
banner, footer, or a sidebar table of contents the developer wants
displayed on every page of their application.
In the HTML DB development environment Page Zero
is used to display the main tab list you see at the top of every page
in the Application Builder, SQL Workshop,
and Administration applications.
Creating a Page Zero
1.
From the application builder page click the Create Page button.
2.
Choose Blank Page, click Next.
3.
On the Page Attributes page enter 0 in the Page field, click
Next.
4.
On the Page Name page, enter Page Zero for Name, click Next.
5.
On the Tabs page, select the No option, click Next.
6.
Click Finish.
There, now the application will have a Page Zero.
Any item placed on this page will be rendered on every other page in
the application. Viewing the page definition of Page Zero will
display a page as shown below.
