[JELLY] - how to enable logging? (SWT specific)
-----BEGIN PGP SIGNED MESSAGE-----

Hi, I'm experimenting with Jelly / SWT and JFace, with some success. That's a
good thing :-0
However; I *think* Im having problems with a Jexl expression, except I'm not
sure. That's a bad thing.
I'm guessing that my expression is incorrect, and is not being evaluated (I
can use a very simple version of this expression and it works, so I know that
the execution of my script is proceeding to that point at least).
The script is as follows (this sits inside a window tag):
<fillLayout type="vertical"/>
<sashForm type="horizontal" var="sash">
<label text="This would be a tree" parent="${sash}"/>
<scrolledComposite var="scrolled" parent="${sash}" type="V_SCROLL, BORDER"
background="132,251,232">
<fillLayout/>
<composite var="grid">
<fillLayout/>
<label text="yay" background="12,12,12"/>
</composite>
<onEvent type="Resize" var="resizeEvent">
${ grid.computeSize(scrolled.getBounds().width,
org.eclipse.swt.SWT.DEFAULT) }
</onEvent>
${grid.setSize(10, 10) }
</scrolledComposite>
The idea is that when the scrolled-composite is resized, the grid is resized
to fit inside (well, height can vary, width will always be fixed to the width
of the parent).... except nothing happens.
If I change the <onEvent> content to be ${grid.setSize(100,100)} it is shown
larger than the default of 10,10... so I know the event handler is being
called.
Weird thing is, if I put an invalid expression in there, Jelly doesn't fail
with any exception - is this normal behavior? Also, is there a way to enable
more logging (I get *none*), so that I can see what's going on in more
detail?
Lastly, I have a default log4j.properties in the root of the cp, with
log4j.logger.org.apache.commons.jelly.tags.swt=DEBUG
log4j.logger.org.apache.commons=DEBUG
but this appears to have no effect - e.g: I dont see the text "Running
script!", mentioned below in main(). Perhaps log4j is not being used or
initialized?
I am starting the script using:
public static void main(String[] args) {
log.debug("Running script!");
JellyContext context = new JellyContext();
XMLOutput output;
try {
output = XMLOutput.createXMLOutput(System.out);
} catch (UnsupportedEncodingException e) {
throw new RuntimeException("died creating output", e);
}
try {
context.runScript("src/JFaceThumbnailer.jelly", output);
output.flush();
} catch (Throwable e) {
e.printStackTrace();
}
}
