| ReadmeFilePropertyPage2 | | public class ReadmeFilePropertyPage2 extends PropertyPage (Code) | | This page will be added to the property page dialog
when "Properties..." popup menu item is selected
for Readme files.
This page demonstrates conditional property pages which look
different depending on the state of the element. In this example,
the arbitrary condition chosen is whether the Readme file is
greater than 256 bytes in length. If it is smaller than 256 bytes
in length, this will be a placeholder page containing
a simple message. If it is 256 bytes or larger, additional
information will be provided. This information is determined at
runtime.
This class may be reused to implement a conditional property page.
The getPageIndex() method tests the condition and returns the
index of the page to create. The createPage*() methods are called
upon to create the actual pages.
