Thread Subject: add a uicontainer or uipanel to a JPanel

I would like to add either a uipanel or uicontainer that has
MATLAB graphics children to a JPanel. After an evening of
playing around with this but to no avail I thought I'd open
it up to a wider audience. Any suggestions would be very
much appreciated.

Thanks in advance

Andrew

Hi Andrew,
I've tried this too but got nowhere. It really does look
like the matlab graphics are in some sort of Java
containers (you can see this by running Yair Altman's find
Obj
http://www.mathworks.com/matlabcentral/fileexchange/loadFile
.do?objectId=14317&objectType=file)
But they seem to be weird Mathworks wrappers for the java
objects rather than the 'real' thing. My hope was that I
could plot a Matlab graph (hidden), and then just grab the
relevant content pane and put that in a java frame. But I
got nowhere unfortunately.
I'm currently resorting to doing all the plotting in Java
(using JFreeChart), which isn't quite as nice.
If you do find out how to do this, it would be very useful
for lots of people I think.
Cheers
Arwel

That's my experience too. I, and several others, have
asked/pleaded/begged MathWorks to enable Matlab components
(most importantly an axis) to be added to a Java container
(there are other Matlab/Java integration issues, but this is
topmost). We hit a blank wall - MathWorks simply does not
want to do this for reasons which were undisclosed. The
official answer is that this is currently unsupported and
will be added to the list of possible future enhancements
and have a nice day...

Hi Arwel,

I thought as much. I saw your original posting and Yair
Altman's comments and was hoping to do something similar.
I'm sure this must be possible but it's starting to feel
akin to banging my head against a brick wall.

Going down the Java route for plotting isn't something I
really want to do as MATLAB is so good at this. I'm just
disappointed that I will have to resort to creating a
"second class" GUI.

Thank you very much for your reply and I agree that this
would be very useful to a lot of people.

Kind Regards

Andrew

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.

Thanks for the response and all the matlab/java functions on
FEX.

Kind Regards

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.

For those interested, I've just uploaded a new contribution to the File Exchange called UISplitPane (http://www.mathworks.com/matlabcentral/fileexchange/23073), which mimics JSplitPane behavior with full Matlab support. This means that you can add axes and controls to the split-panes (2 uipanels), and they resize automatically when the split-pane divider is moved interactively or programatically. Feedback is most welcome.

Behind the scenes, the basis is much as Amir has hinted, and similar to the uitab/uitabgroup implementation: I've taken the divider portion of the JSplitPane and coupled it to 2 standard Matlab uipanels as sub-panes. Matlab axes and controls can now easily be added to the uipanels. Property listeners and schema property set-function setup then ensure consistency between the Java and Matlab parts. Special handling was added to ensure usability even in non-Java-enabled Matlabs (e.g., Matlab 6.0 aka R12).

I assume this alleviates a major need in Matlab-Java integration but the basic request from all responders in this thread remains unchanged, quoting Amir: *PLEASE* "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"
