Tutorial Runtime Error
Hello,
I am up to the part of the tutorial: http://cwiki.apache.org/PIVOT/labels-
image-views.html and am doing something wrong but can't figure it out.
Instead of just using the tutorial code as is I like to change things slightly
so that I get a better feel for the toolkit. So I changed the location of the
clock.png file but I get a "Null Image Alert" from the following code:
<Window title="Labels" maximized="true"
xmlns:wtkx="http://incubator.apache.org/pivot/wtkx/1.1" xmlns="pivot.wtk">
<content>
<FlowPane styles="{padding:4, verticalAlignment:'center'}">
<ImageView image="/home/scott/devel/src/clock.png"
cursor="crosshair"/>
<Label text="What time is it?"/>
</FlowPane>
</content>
</Window>
The file does exist in that location as I can take the path and paste it into a
graphics editor. Any help appreciated.
Cheers,
Scott.

Thanks for the link I will have a look.

Thanks. Sounds like I had better change over to 1.3.

The "deploy" target will build a set of jar files (our libraries) and war
files (our demos and tutorials) into the lib directory. To build the
javadocs, run the "doc" target. Alternatively, it's not linked to yet, but
you can get fairly up-to-date javadocs for the 1.3 snapshots at
http://incubator.apache.org/pivot/1.3/docs/api/

Ah. That's probably because the deploy target runs the clean target,
which deletes the docs. Maybe deploy should also run the doc target
(or not run clean beforehand). For now, you can just re-run the doc
target to get the Javadoc back.

The code from SVN built okay but when I ran the deploy target the API docs
went missing.

As Todd mentioned earlier, you may be better off working through the
tutorials from SVN. Quite a few things have changed between 1.2 and
1.3, particularly in the area of WTKX.
I'd recommend that you get the latest source and run the deploy
target, since that will build the latest version of the tutorial apps
and documentation. However, if you just want to read the WTKX Primer,
you can get it here:
http://svn.apache.org/repos/asf/incubator/pivot/trunk/tutorials/www/wtkx_primer.template.html

Actually, in case you haven't read it yet, the WTKX primer on the Wiki is a
really good resource. It can be found at

Re: Tutorial Runtime Error

Hi Scott,
<ImageView image="..." /> translates to ImageView.setImage(String) (
http://incubator.apache.org/pivot/1.3/docs/api/org/apache/pivot/wtk/ImageView.html#setImage(java.lang.String)),
where the string is a resource name as per ClassLoader.getResource(String) (
http://java.sun.com/javase/6/docs/api/java/lang/ClassLoader.html#getResource(java.lang.String)
).
Thus, the path to your image must be found on your classpath.
Alternatively, you can prepend the string with "@" and use a relative path,
in which case the value will be converted to a URL relative to your WTKX
file, and Imageview.setImage(URL) will be called.
Hope that helps,
