gov.sandia.ccaffeine.dc.user_iface.MVC.event.ParamDefaultEvent
public class ParamDefaultEvent
Cca components contain ports. Some of the ports contain data fields. This event can be used to notify components that the cca server is sending the default value of one of these data fields. A view entity might respond by checking the state of a data field; if the data field does not have a current value then the default value is displayed on the screen.
Possible Scenario:
An end-user clicks on a blue port inside of a component
client sends "parameters" to server
serer- sends "ParamDialog" to client
client responds by creating an empty dialog box
server sends "ParamTab" to client
client responds by inserting a new tab in the dialog box
server sends "ParamField" to client
client responds by inserting a blank data line into the dialog box
server sends "ParamCurrent" to client
client responds by inserting the data's value into the dialog box
server sends "ParamHelp" to client
client responds by setting the text that is displayed if the help button is clicked
server sends "ParamPrompt" to client
client responds by displaying a prompt to the left of the data's value
server sends "ParamDefault" to client
client responds by setting the data's default value
server sends "ParamStringChoice" to client
client responds by setting an item in the value's choice box
server sends "ParamNumberRange" to client
client responds by setting the data value's range of allowed values
server sends "ParamEndDialog" to client
client responds by displaying the dialog box on the screen
