Thanks Yair,

An axis is ultimately what I wanted to add to to a
JPanel
but I figured that a uicontanier or uipanel in which an
axis
can sit might be more native to the Java environment.

The short answer to the posted question is you can't do
that.

The uicontainers and uipanels and axes, for that matter,
just can't be put in arbitrary Java components. It's not
that we don't want to make it possible, it's just a
ton of
work and other priorities keep coming up.

As for putting an axes in a Java container, you can
use the
print or imwrite commands to dump the contents of a
figure
into a bitmap then shove that into any Java canvas which
can show a bitmap. We've done some hackery where you
take
the output from imwrite and stuff it onto a JButton for
example.

As for putting non-bitmap axes into Java containers,
could
you tell me more about why you want to do it? What is
the
MATLAB thing you can't do without this capability?

Thanks,

Bill


Thanks a lot for your comment Bill. It is sometimes
important to place Matlab axes in Java containers, since
Java (Swing in particular) enables richer GUI than Matlab
enables. For example, if I need JSplitPane functionality I
have to rely on Java, not Matlab, but then I cannot add a
Matlab axes to either side of the split-pane, which is a
major drawback. You'll agree with me, I hope, that
reprogramming a JSplitPane from scratch in Matlab just to
solve the axes issue would be a shameful waste...

Remember that Matlab axes (& children) are rich objects
themselves, and simple imwrite falls far short of the needs
(callbacks and online data updates are just two examples).

If only an axes could be placed within a JContainer, that
would automatically solve all these issues, for all Swing
components.

Bill,

At the time of posting I was looking for the same
functionality that Yair Altman has mentioned, that of a
JSplitPane. It is not a trivial exercise to code one up
from scratch. Also the results will never be as robust,
fluid or aesthetically pleasing as a JSplitPane.

Thanks for your suggestion of using imwrite or some other
such method but as Yair has pointed out, I also want to
maintain the functionality of an axis object i.e callbacks
and what not.

Bill,

As you know from our past correspondence, there are ways (at
least two I'm aware of) to make a java/matlab figure hybrid
that have java GUI and matlab graphic (aka "the holly
grail"). However, both are non-trivial, non-intuitive, have
limitations (for example, making sure the java components
resize after the user resize the matlab figure) and require
heavy usage of undocumented features. Moreover, it seems
that new Matlab version frequently break such hacks that
worked in the previous version (no real complains here, as
those hacks use UNDOCUMENTED features). However, one gets
tired from using those hacks and want to just implement the
needed business logic instead of fighting with Java/Matlab
integration issues.

Can you comment on when (if at all) will Mathwork be able to
implement a java wrapper around matlab axis that extends
java.com.Component, so we could just drop it inside our
favorite java container as god intended and go on with our
lives.
