In reply to Yiftach. Thanks Yair! I will give it a try Yiftach

@Yiftach – you can use App Designer and related uifigures/controls – this displays the GUI in a webpage which does not use Java Swing or EDT.

Hi Yair,
Thanks a lot for all the examples and information. I have a short question – is there a way to create a matlab GUI off the EDT, i.e. make a matlab GUI which runs on a different thread? I’m using matlab as an interface to a 3rd party application (MicroManager), which uses EDT according to its developers. It seems like matlab’s GUI is interfering with their GUI. Is there a way to bypass this problem somehow? I would greatly appreciate your reply

Thank you very much in advance,
Yiftach

Hi Yair,

I’m interested in the last little bit on the callbackOnEDTQueue() function at the end. In testing this seems to solve my problem of trying to delay running a computation until some later point in time, allowing the rest of the axes to render following a xlim change.
https://www.mathworks.com/matlabcentral/answers/368964-queue-addlistener-events-or-place-event-on-edt

This seems like an alternative to the following post: http://undocumentedmatlab.com/blog/matlab-callbacks-for-java-events#comment-418911

Where my general use case would be to call the notify event (in the linked blog post) directly from Matlab: i.e. evt.notifyMyTest rather than from Java as the linked post is really about.

Am I understanding the callbackOnEDTQueue() function correctly, that it appears to serve the same functionality as the evt class in the link, without the need for writing a Java class and adding it to the Matlab path?

I guess I am confused by this statement:

%Note that the function is still executing on the main Matlab thread. This
%function just delays when it will be called.

What are the practical implications of that statement?

Thanks as always,
Jim

In reply to Peter. Hi Peter May I ask if you found a solution to the tab-completion issue ?

In reply to Peter. I have no immediate answer on this

Hi Yair,
I am building a pure Java Swing GUI for our backend Matlab application. Matlab starts the GUI using the javaObjectEDT() method. Unfortunately, running the GUI in this thread makes Matlab’s tab-completion unresponsive. Do you have an idea where this might come from and how to circumvent it?
Thank you very much for your help
Regards,
Peter

Hello Yair,
Is there a chance to create a table with one image icon type (or button like, if possible) column using javaObjectEDT and some default table/cell renderers and editors?
I implemented my own Image Renderer derived from DefaultTableCellRenderer java class (with one label and one imageIcon attributes), compiled & tested it using simple java program, zipped the .java and .class files (+ added one .png icon) but javaObjectEDT function ignores it completely and throws an exception : “No class ImageRenderer can be located on the Java class path”.
What would you recommend me?
Many thanks
