Re: [vtp-dev] Browser API Tutorial

[Brent D Metz <bdmetz@xxxxxxxxxx>]

For #1, sorry for the confusion. I think
this needs to be clearer in the tutorial. setDefaults()/initializeFrom()
are concepts lifted from Eclipse's ILaunchConfigurationTab. There is a
tutorial that talks about the APIs here:

http://www.eclipse.org/articles/Article-Launch-Framework/launch.html

Its description of the two functions
is:

"In general terms, the first two
methods copy values from the tab to a working copy, while the third method
copies values from a working copy to the tab.  The setDefaults() method
is called when a new config is created. "

"The initializeFrom() method does
the opposite of the performApply() method.  It reads attribute values
out of the config argument, and sets these values in the corresponding
GUI widgets"

#2: Right now isValid is a simple boolean
function and error messages would have to be inserted as widgets inside
the configuration pane. This is something that I think needs better integration
with the launch configuration UI, and I'd suggest you write the code with
this in mind so that it would be simple to change the return type later
as we modify the interface. I've created a bugzilla to track the enhancement:

Hi all,

here are some more questions regarding the 'Getting Started' manual.

1. What is the difference between IBrowserConfigurationUI.setDefaults()
and IBrowserConfigurationUI.initializeFrom()?

As far as I understand the javadoc, the configuration values should be
stored in setDefault() whereas in initializeFrom() these values are
taken and displayed in the UI.

The example shows a simple copy of that.

I need an answer if I got it right to finish my work on the JVoiceXml
integration.

2. Unfortunately the isValid() has very little interaction capabilities
and is not explained in the example.

My main problem is how to provide the information about the cause of a
failed validation to the user.

Is there a common concept for this?
