Notes Regarding This Applet

Note: Depending on the platform and browser you are using you may receive a security error when attempting to view and modify this demo on a local computer. In Internet Explorer the applet will simply not run without indicating a security error, even though it is most likely the cause, Netscape will show the error message in the Java console. To avoid this error place all your files (class, text, and HTML) in the same folder or configure the applet on the web server. This error will not occur once the applet and text files are placed on the internet.

Note: When uploading your class files and HTML document to the sever make certain that the class files are uploaded in binary format and the codebase value in the applet tag appropriately point to the location of the class file (If the class file is in the same folder as the HTML document containing the applet leave the codebase command out of the applet tag).

Applet Tag Templates

Template One - Based on above sample

Information about the applet and its parameters

Required Parameters

Parameter 1 (the "notice" tag) must be included in the applet tag in order for the applet to work. Most of the parameters will default if you fail to define them, at a minimum you must include the notice tag and billboard images.

Defining Colors

This applet uses a simple RGB or Hexadecimal color definition scheme. On most systems (depending on the software being used to choose a color) its easier to define a color using RGB, however since most web pages define colors using a HEX value we have allowed for both methods of color definition. To define a color using RGB use commas to separate the values such as 255,255,255 (White). To define a color using a hexadecimal value use a pound sign ('#') followed by a 6 digit hex value in the rage of 000000 - FFFFFF (e.g. #FFFFFF is equal to the color White).

Color Definition with RGB: To define a color in one of the color parameters using RGB choose a value between 0 - 255 for the red, green, and blue components separated by commas and typed out in the correct r,g,b order. Below is a sample of how a color parameter using RGB should look, the example specifies several different sample colors for the "bgcolor" parameter.

WHITE: <param name="bgcolor" value="255,255,255">
GREEN: <param name="bgcolor" value="0,255,0">
BLACK: <param name="bgcolor" value="0,0,0">
YELLOW: <param name="bgcolor" value="255,255,0">
OFF WHITE: <param name="bgcolor" value="240,239,234">

The best way to choose the exact color you are looking for without having to guess the numbers is to access your systems Color Picker. Color Pickers usually allow you to drag the mouse over a rainbow type color grid to select a color, and show you the appropriate RGB values. In windows the Color Picker is accessible through MS Paint as well as a majority of the popular Imaging and HTML Authoring Software.

Defining Multiple Attributes with the same parameter name

Parameters used to customize a specific message are indicated using a range, such as "desc0" - "descN". To define a parameter for a specific message (available when noted as above), use "textcolor0" to define, in this case, the text color for the first message - "textcolor3" would define the text color for the fourth message, etc., etc.

Applet Parameters

General Settings

param name = "stallmover"
Value = true or false, true = yes, stall the billboard when the mouse is located over the image, false = no, transition the billboards regardless of where the mouse is.
DEFAULT: true

Parameter 5
Attribute: Mouse Off Billboard Delay if Time Expired
param name = "offdelay"
Value = X where x is the amount of time in seconds to transpire before switching to the next billboard once the mouse moves off the image,
DEFAULT: 2

The Image Files

Attribute: Default Delay Timing
param name = "delay"
value="X", where X is the default time to display each billboard image in seconds.
DEFAULT: 3

Parameter 8
Attribute: Specific Delay Timing

Parameter 19
Attribute: Default Load Destination Image URL Where?
param name="loadwhere"
The "loadwhere" tag specifies where the document specified in the "URL" value should be loaded. The default is "_self". A value equal to the name (case sensitive) of a frame will load the document in that frame.
