How to dynamically add component to window
Hi,
I must say I'm totally new to Pivot. I'm trying add a box pane to my window's scroll pane but even the code compiled properly, the box pane just doesn't show up.
Here is the snippet from my main program.
@Override
public void startup(Display display, Map<String, String> properties) throws Exception {
String language = properties.get(LANGUAGE_KEY);
Locale locale = (language == null) ? Locale.getDefault() : new Locale(language);
Resources resources = new Resources(ClientWindow.class.getName(), locale);
BXMLSerializer bxmlSerializer = new BXMLSerializer();
window = (ClientWindow)bxmlSerializer.readObject(getClass().getResource("client_window.bxml"),
resources);
ScrollPane rightScrollPane = (ScrollPane) bxmlSerializer.getNamespace().get("rightScrollPane");
BoxPane commentPane = null;
try {
commentPane = (CommentPane)bxmlSerializer.readObject(getClass().getResource("thumbnail/comment_pane.bxml"),
resources);
} catch (IOException e) {
e.printStackTrace();
} catch (SerializationException e) {
e.printStackTrace();
}
rightScrollPane.add(commentPane);
window.open(display);(display);
What do you recommend to do this job in pivot?
Thanks in advance!
Brendan

Can you show me an example?How do you modify you Web Queries example to achieve?I'm not clear where to the serializer. Do you use bxml:include like this:<itemRenderer><bxml:inlcude src = "ResultItemRenderer.bxml"/></itemRenderer>

Yes, you can easily create a list item renderer whose structure is defined in BXML by using a root element that implements the ListView.ItemRenderer interface. For example, you could create a subclass of TableView called CommentItemRenderer that implements this interface. You could use @BXML annotations to get access to the dateLabel, authorLabel, and summaryLabel elements so you can set their values in the render() method.

Sounds like this might be a good use case for a custom list view item renderer. Here is an example:

if I use BXML serializer, i can load one into my scroll pane with setView. but when I load a second one, I have an error message "ID dateLabel is already in use".
I can't use bxml:include in bxml file because I don't know until I read the database.
Hopefully, that's clear.

This example show the format of ListView is created inside java code, so that to change the style of the list may have to change the code.But I want to make use of BXML file for the ListView, is that possible to achieve in Pivot?

My program need to show a series of comment displayed in a sroll pane somewhere in my main window.I created a bxml file called CommentPane which take three variables Date, Author and comment.And the list of comments stored in database.
so my CommentPane code like this:<thumbnail:CommentPane

<TablePane.Row height="-1">

Re: How to dynamically add component to window

I don't really understand what you are trying to do, and I can't tell
if you have code that doesn't work or if you are just asking a
question about how to 'inject a series of box pane from the bxml
files'.
If you are seeing Exceptions thrown somewhere, please post them to the
list, and if possible, include a small example application
demonstrating the problem.

Are you talking about using BXML's 'include' functionality?
http://pivot.apache.org/tutorials/bxml-primer.html
If you are, then you can include the same BXML fragments multiple
times (or any fragments, including ones where the BXML IDs of
Components might clash) by using the inline flag
<bxml:include src="foo.bxml" inline="true"/>

Or are you talking about loading BXML files in your Java code (using
BXMLSerializer) and then doing something with them?
Here is an old mailing list thread which talks about reusing
BXMLSerializer to load multiple BMXL files.

Chris,
Thanks so much and it works!
Actually, I was trying to inject a series of box pane from the bxml files. Do I have to use the bxml Serializer repeatedly?Or do I have to use java code instead of? how to handle the variables in BXML because they have the same names.?

Brendan,
I think this is your problem.
> rightScrollPane.add(commentPane);
Try replacing it with
rightScrollPane.setView(commentPane);
Some background if you are interested ...
ScrollPane is an instance of ViewPort, which is in turn an instance of
Container. http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/ScrollPane.html
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/Viewport.html
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/Container.html
Some Containers (like BoxPane) simply display whatever child
Components were added to the Sequence<Component> that Container
provides.
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/BoxPane.html
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/collections/Sequence.html
Others Containers (like ScrollPane) are a little more complex and can
display additional UI elements. In the case of ScrollPane, it can
display a 'rowHeader', 'columnHeader', and 'corner' as well as a
'view'.
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/ScrollPane.html#setRowHeader(org.apache.pivot.wtk.Component)
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/ScrollPane.html#setColumnHeader(org.apache.pivot.wtk.Component)
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/ScrollPane.html#setCorner(org.apache.pivot.wtk.Component)
http://pivot.apache.org/2.0/docs/api/org/apache/pivot/wtk/Viewport.html#setView(org.apache.pivot.wtk.Component)
ScrollPane therefore needs to manage the Sequence<Component> provided
by Container, so you need to tell it what to do with the Components
that you give to it, rather than adding them to the
Sequence<Component> directly (which is what
rightScrollPane.add(commentPane) looks to be doing).
In your example you want to show your 'rightScrollPane' Component as
the ScrollPane's 'view'.
'view' is the default property of ScrollPane (inherited from
ViewPort). This is defined via the @DefaultProperty annotation.
http://svn.apache.org/repos/asf/pivot/trunk/wtk/src/org/apache/pivot/wtk/Viewport.java
Unfortunately, the DefaultProperty annotation is not shown in the
Pivot 2.0 Javadocs, but it is always visible in the source code. From
2.0.1 (which will hopefully be released soon) the DefaultProperty
annotation *will* be visible in the Javadocs.
