Dear Yair

This looks like a great utility. Unfortunately it does not work properly on my system (Matlab 2010a, Windows XP, Java 1.6.0_12-b04). To start with I call

hIcon = systray('C:\Program Files\MATLAB\R2010a\toolbox\matlab\icons\help_ex.png');

Afterwards, the only command that works is the set command for deletion. Setting message pop-ups and the like does not work (does not yield any error messages, but does not affect the icon).

Furthermore, if I click the icon in the system tray I get the exception pasted below.

Have you any suggestions on how to get around this. I have tried the exception fix you link to on the uisplitpane post, but that does not help either. Thanks for a great site and lots of cool applications

Peter

@andandgui – did you even read the SoundVolume help?

SoundVolume is not a variable that you can assign like SoundVolume=10, but a function that accepts input parameters like SoundVolume (1.0) and it only accepts values between 0.0-1.0 so 10 is not a valid value.

Also, next time, please post the question in the relevant page (http://undocumentedmatlab.com/blog/updating-speaker-sound-volume/) – your question has nothing to do with this page.

i couldn’t run SoundVolume function on Matlab.. When i write SoundVolume=10; then nothing happens .. How can i run the SoundVolume function which is written at

Albert – it should work on Matlab installations that run JVM 1.6+. To determine your JVM version, type the following in your Command Window:

version -java

If this is not helpful, try to inspect the trayIcon object using the methodsview function, to see why the getClass method fails:

methodsview(trayIcon);

On the version (R2007b) of Matlab I use this statement does not work:
trayIconClasses = trayIcon.getClass.getClasses;
??? No method ‘getClass’ with matching signature found for class ‘java.awt.TrayIcon’.

Is it supprted on later versions?

[...] Unfortunately, Matlab prevents using Java classnames containing a period (e.g., Port.Info) or static Interface values, so we cannot directly access Port.Info.SPEAKER or FloatControl.Type.VOLUME. I’ve reported this bug to Mathworks earlier this year, and I do not know in which Matlab release (if at all) they intend to fix it. Until then we need to use workarounds, as in the code above. I posted a similar issue (and its workaround) earlier in this blog, when setting system-tray popup message. [...]

Yair,
Thanks again for this utility, just thought I would let you know that I’m using this to replace any helpdlg boxes that I previously used to give process direction during a program, like click here, or define this range. Using this, a user can breeze through a program if they know what to do, or go slowly and read the pop-ups.
