Creating the Render Function
Just like the other plug-ins, this plug-in will store its PL/SQL code in the
pkg_apress_plugins
package. To
start, get the region plug-in render function template and paste it into
pkg_apress_plugins
spec. Name
the render function as f_render_rss_reader. Your
pkg_apress_plugins
package specification should now
look like Figure 5-17.
■
Hint
To get the render function spec template, click render function label and view the help file.

The next thing you'll need to do is register the render function with the plug-in. Edit the plug-in and
scroll down to the Callbacks region. Set the
Render Function Name
to
pkg_apress_plugins.f_render_rss_reader, as shown in Figure 5-18.
