@Mike – thanks – couldn’t ask for anything more

That looks like a “bug.” I’ll ask them to fix it, but the earliest it would be done would be 12b, if at all…

@Alexander – using menuItem.setEnabled() is indeed safe and valid, and in fact better than using set(…). Your fix for using CallbackProperties is also correct – this is described in another article.

Unfortunately, I do not have a solution for the popup message errors at this time. If I do, I will post it on this page.

Update:

Going through the implementation in 2010b I found a second problematic point. In line 232, the “ActionPerformedCallback” is set. This also drops an warning. Now I found on of your infos on using set/get with core java object in the entry on Uicontrol callbacks. Is it thus reasonable to change

set(menuItem,'ActionPerformedCallback',get(thisItem,'Callback'));

set(handle(menuItem,'CallbackProperties'),'ActionPerformedCallback',get(thisItem,'Callback'));

If so, I’d suggest to make an update of the FileExchange version (also including the comments made in the uisplitpanel entry). If not, I’m really interested in a workaround.

Dear Yair,

as all the others I’d like to thank you for the wonderful systray tool. It’s really great.

While I implemented it these days in an old 2007b installation, it worked without any problem. (At least after having included the solution for the messages as pointed out in your uisplitpane entry).

Now I’m trying to migrate to 2010bSP1 and stumbled over two problems:

a) Java complained about setting the popup entry enabled using your line

set(menuItem,'Enabled',get(thisItem,'Enable'));

As I’m not familiar with java: Is the workaround

menuItem.setEnabled(strcmp(get(thisItem,'Enable'),'on'));

valid?

b) I get the same error message as Peter mentioned above when trying to access the popup menu:

As I learned, this is an Java 1.6 issue. Is there a workaround on the Matlab-level for systray available? Or what else could be done?

Best wishes,

Alexander

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
