|
|
<p>This
|
|
figure illustrates how the elements of the Graphical Toolbox runtime environment
|
|
interact with application code.</p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Description</h4><p>The figure is composed of several boxes
|
|
of differing shapes, sizes, and colors that are connected to each other by
|
|
lines terminated by arrowheads at one or both ends.</p>
|
|
<p>In order to visualize
|
|
the figure, it is useful to divide it into three columns and four rows, numbering
|
|
the areas in sequence from top left to bottom right. fo example, The first
|
|
row contains areas 1, 2, and 3; the second row contains areas 4, 5, and 6;
|
|
and so on:</p>
|
|
<ul><li>The image of a dialog box that occupies areas 2 and 5 represents the GUI
|
|
interface for your Java program. The dialog box features a
|
|
variety of options, like check boxes, text fields, and so on.</li>
|
|
<li>Two tan cylinders at the top of area 1 are labeled PDML Source and Resource
|
|
Bundle. These cylinders represent PDML source and Java resource files that reside on a storage
|
|
medium.</li>
|
|
<li>One tan cylinder in area 10 labeled PDML Serialized represents one or
|
|
more serialized PDML files that reside on a storage medium.</li>
|
|
<li>Five blue rectangles that surround the bottom portion of the dialog box
|
|
represent components of the Graphical Toolbox. Starting at the leftmost rectangle
|
|
and moving counter-clockwise, they are labeled: <ul><li>XML Parser (Pure Java) in area 4, which represents the IBM XML
|
|
Parser.</li>
|
|
<li> Runtime Managers (Pure Java) in area 7. Your Java program
|
|
is a client of one or more of the objects contained in Runtime Managers:
|
|
Panels, Property sheets, Wizards, and Layout.</li>
|
|
<li>Common Data Exchanger (Pure Java) in area 8.</li>
|
|
<li>Common Formatters (Pure Java) in area 9.</li>
|
|
<li>Common Handlers (Pure Java) in area 6.</li>
|
|
</ul>
|
|
</li>
|
|
<li>Three green rectangles represent code provided by the application programmer
|
|
and are labeled: <ul><li>Custom Handlers (Java Application) in area 3</li>
|
|
<li>Custom Formatters (Java Application) in are 12</li>
|
|
<li>User Interface Data Beans (Pure Java) in area 11</li>
|
|
</ul>
|
|
</li>
|
|
<li>Lines connect many of the shapes: <ul><li>A line that has a single arrowhead (on one end) indicates an action.
|
|
Single arrowhead lines point toward a function or component that uses the
|
|
object from which the line originates. In the following description, the
|
|
word "use" means that a line with a single arrowhead points toward an object
|
|
from the component that acts upon it.</li>
|
|
<li>A line that has a double arrowhead (one at each end) indicates an interaction.
|
|
These lines connect objects that share a two-way exchange of information.
|
|
In the following description, the word "interact" means that the components
|
|
are connected by a line with a double arrowhead. </li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
<p>The GUI interface for your Java program (the image of the dialog in
|
|
areas 2 and 5) interacts with the Runtime Managers for the Graphical Toolbox
|
|
(the blue rectangle in area 7).</p>
|
|
<p>The Runtime Managers, which are pure Java,
|
|
contain panels, property sheets, wizards, and the GUI layouts. To generate
|
|
the GUI, the Runtime Managers use a Java resource bundle (one of two tan cylinders
|
|
in area 1) and PDML data. Runtime Managers can process PDML data in one of
|
|
two ways:</p>
|
|
<ul><li>Using serialized PDML files (the tan cylinder in area 10)</li>
|
|
<li>Using the IBM iSeries™ XML
|
|
Parser (the blue rectangle in area 4), which in turn uses (parses) the PDML
|
|
source files (one of two tan cylinders in area 1)</li>
|
|
</ul>
|
|
<p> Your GUI-enabled Java program operates on data in one of
|
|
the following ways:</p>
|
|
<ul><li>Having the GUI interface interact with custom handlers (the green rectangle
|
|
in area 3) and common handlers (the blue rectangle in area 6)</li>
|
|
<li>Having the common data exchanger (the blue rectangle in area 8) use the
|
|
GUI interface to obtain information</li>
|
|
</ul>
|
|
<p>The custom handlers, common handlers, and the common data exchanger
|
|
all interact with the user interface data beans (the green rectangle in area
|
|
11), passing information back and forth. The common data exchanger interacts
|
|
with common formatters (the blue rectangle in area 9) and custom formatters
|
|
(the green rectangle in area 12) to convert the data into appropriate formats
|
|
for the user interface data beans.</p>
