| Sample JSP: Building &
Using Component Factory for Air Traffic Monitoring |
| |
| This
simple JSP file demos, how one may use a Component factory
for the Air Traffic Control System using the Raju’s
GUI-Class for the Airline. This demo shows, how one
may use the CF to build one more layer of hierarchy. |

| |
| The
following JSP-code presents the above SVG-component.
The JSP code is in one file, but it is dived into sections
to explain then in parts. To inspect the SVG-code of
the AC’s, please select right mouse button and
select “View Source” in the pop-up menu. |

| The
JSP file to present the Above SVG-Component |
| |
Note:
Please click on this link (ATC_CF.java) to see quick
and dirty/lazy code for the CF, to build given City’s
Air Traffic monitoring component. The ATC_CF-Class takes
a City’s Airport code (e.g. SFO for San
Francisco or LAX for Las Angeles
International) as input and generates the AC to present
the Air traffic-monitoring component. |
| |
Please
review the Section-3 code to see, how one could use
the Raju’s “Component Factories” for ATC-system may
be used to build subcomponents for a container-component
(e.g. Rotate Banner). |
| |
//
Instantiate the ATC for each City.
ATC_CF Atc1 = new ATC_CF (aci, "SFO",
data_url);
ATC_CF Atc2 = new ATC_CF (aci, "LAX",
data_url);
ATC_CF Atc3 = new ATC_CF (aci, "JFK",
data_url);
// One may use
each of the above Objects to build subcomponents.
// Pass the City-CF-Object
information to a Rotate banner Component
ATC_CF City_list[] = {Atc1, Atc2, Atc3};
RotateBanner3 RB = new RotateBanner3(aci, City_list,
3);
RB.CGM(pw); |

The
final section contains Radio-buttons to switch between
the cities to monitor the Air Traffic. This demo is
showing just one layer or hierarchy, but this kind of
hierarchy can go on for many layers. For example, yet
another container component’s Object may use the Rotate-Banner
object to build its subcomponent; and so on. There is
no limitation, and this process can be repeated for
many layers. Likewise, a taxi-company may monitor taxi-movements
and status in different sections of the town. The City
map may be obtained using Google’s map API. |

The
online GUI-Classes could offer every thing one might
expect from traditional GUI-classes (e.g. Java/Swing
or Windows-API) and lot more. In many aspects, Raju’s
GUI-classes may be simple to use, more flexible and
superior to traditional GUI-classes. |
