Description:
In this assignment you will construct one class called "SimpleBrowser".
SimpleBrowser is a JFrame and must meet the following requirements:
1) Render HTML Pages
- To render HTML, SimpleBrowser will use the HTMLViewer class,
"HTMLViewer.java".
This class renders the html page, in a JEditorPane. To construct
an HTMLViewer, you must pass a reference to your SimpleBrowser
class as follows:
HTMLViewer htmlViewer
= new HTMLViewer( this );
2)
File Menu - Your application must provide a file menu, called
"File", with one menu item for exiting the browser, called
"Exit".
The file menu should look like:
The exit menu item must terminate the program
when a user clicks on the "Exit" menu item.
2)
About Menu - Your application must provide an help menu,
called
"Help", with one menu item for
displaying information about the program. The help menu must
contain one menu item, called "About".
The file menu should look like:
The about menu item must display a dialog when
the user clicks on the menu item that states "Simple Browser"
and your name. For my application it looks as follows:
3) URL Label and
Text Field - Your program must provide an area for the user
to type
the url they would like to view. This
text field needs to be labeled as "Address:".
In addition, your text field must allow the user to type a
url and press the
enter key, then change the page. To change the page in the
HTMLViewer,
you need to call the "setWebPage(String
url)" method. So you
need to listen for the "Enter Key" in
the text field and call "setWebPage(String
url)". Your program must also check the make
sure that the url starts with "http://".
If the url the user typed doesn't contain "http://",
you must add it to the user's url.
htmlViewer.setWebPage(newURL);
The URL area looks
as follows:
4)
Status Bar - Your application must have a status bar in the
bottom of the application. The status bar does not have any
functionality, just presentation appeal. The status bar is
created with a JPanel and added to the main application frame.
5)
Changing the address - Your application must implement the
URLSetable interface. This interface has one method which
allows the user to change the text in the address text field.
HTMLViewer uses this method when a user clicks a link on
a page to display the appropriate web address. You will need
URLSetable.java
