Depending on which of the three options you use to access information using your Java classes, this information must at some point be saved back to a file (probably to the one from which it was read). When the user of your application invokes a File->Save action, the information in the application must be written out to an ApplicationML file. Now this information is stored in memory, either as a (DOM) tree of nodes, or in your own proprietary object model. Also note that most DOM XML parsers can generate XML code from DOM document objects (but its quite trivial to turn a tree of nodes into XML by writing the code to do it yourself). There are 2 basic ways to get this information back into an ApplicationML file:

There are advantages and disadvantages to using some of the strategies to import and export XML. The complexity of your application data and available system resources are factors that would determine what strategy should be used.

content edge of the ancestor. In left-to-right languages, the top andleft of the containing block are the top and left content edges ofthe first box in the ancestor, and the bottom and right edges are thebottom and right content edges of the last box. In right-to-leftlanguages, the right edge of the containing block corresponds to theright content edge of the first box, and the left is taken from thelast box. The top and bottom are the same.

If there is no such ancestor, then the content edge of the root

11.2.5. Getting Full Content Backgrounds in Navigator

We covered this in Chapter 6, "Colors and Backgrounds", but it bears some repetition. We assume you want people using Navigator 4.x to see full background colors in text elements, not just behind the text. If you've applied a background color to a text element, add the following declaration: border: 0.1pxsome reason, the user agent will use the background color specifiedin place of the image. Consider how the "starryparagraph" example would look if the background image failed toload, as in Figure 6-26.

Figure 6-26. The consequences of a missing background image

Given this reason alone, it's always a good idea to specify abackground color when using a background image, so that your whitetext will at least be visible:
