First Attempt at Pivot 2.0
Hi
I'm trying to convert from Pivot 1.5 and I'm trying to use the Bindable
interface, but I'm obviously missing something as the initialize() method is
never being called. Sorry, I know that the code is a mess, but I'm just
trying to get things working at this stage.
Any suggestions? This is my first and only Pivot application so please keep
it simple :)
Regards

Re: First Attempt at Pivot 2.0

Due to the @DefaultProperty annotation on most Pivot WTK classes, you
can simplify your BXML quite a lot now.
See the section titled 'Default Properties' in the BXML Primer
http://pivot.apache.org/tutorials/bxml-primer.html
In the BXML below, it means you no longer need to specify these tags
<content></content>
<view></view>
Unfortunately the annotation won't usually show up in the Javadoc for
the class, but can be seen in the source code.
For example, you can see that 'content' is set as the default property
in the source for Border
@DefaultProperty("content")
http://svn.apache.org/repos/asf/pivot/trunk/wtk/src/org/apache/pivot/wtk/Border.java
The full source can be downloaded here, or grabbed from SVN
http://pivot.apache.org/download.cgi#2.0
http://pivot.apache.org/svn.html
The FAQ explains how to reference the source in Eclipse

Re: First Attempt at Pivot 2.0
Posted by Chris Bartlett <cb...@gmail.com>.
Have a quick look at the section titled 'The Bindable Interface' in
this if you haven't already
http://pivot.apache.org/tutorials/bxml-primer.html
The initialize method will be called on *just* the root object of the
BXML file, not on the Application. In your case the root object is a
standard org.apache.pivot.wtk.Frame.
So BXMLSerializer will attempt to call initialize on the 'window' variable here
BXMLSerializer wtkxSerializer = new BXMLSerializer();
window = (Window) wtkxSerializer.readObject(Example.class,
"GenesisClientStarter.wtkx");
Instead of using a Frame, you can extend Frame and implement Bindable.
Then when the BXML is loaded by BXMLSerializer, it will call the
initialize method on that custom subclass of Frame.
Here is an example from the 'examples' project in the Pivot SVN repository.
http://svn.apache.org/repos/asf/pivot/trunk/examples/src/org/apache/pivot/examples/scripting/JavaWindow.java
http://svn.apache.org/repos/asf/pivot/trunk/examples/src/org/apache/pivot/examples/scripting/java_window.bxml
Don't hesitate to ask if you have more questions.
