Yerlan – either use menuItem1.setEnabled(0) or set(menuItem1,'Enabled',0)

how can I disable menu items in the context menu?

E.g. when I am trying to do this:

menuItems = jmenu.getSubElements;
menuItem1 = menuItems(1); 
set(menuItem1,'setEnabled',0);

I get an error: “The name ‘setEnabled’ is not an accessible property for an instance of class ‘javax.swing.JMenuItem’.”

Thank you.

Best regards,
Yerlan

@Hironori – callback functions run asynchronously, not synchronously, so they do not return any value. You can save the results in some persistent place (like a global variable or the figure’s UserData property) and in your main program you can later access this data. You can read about Matlab callbacks and how to use them in Matlab’s standard documentation.

Thank you for this variable informations

How could I get the Output variable from the function “myFunc2” using the command
“set(menuItem2,'ActionPerformedCallback',{@myFunc2,data1,data2});” at this case?

% -- Example
function output = myFunc2(hObject, eventData, myData1, myData2)
output = myData1 + myData2;
end

I need to get the variable “output” into my main function after the mouse right button action was performed.

Will you please advise me for this?

Thanks in advance

@Ian – try to call the Java object’s repaint() method (function), after adding it to the panel (presumably using a call to javacomponent)

I am trying to create a uitree one a resizable panel created with your uisplitpane() function.

The tree won’t show up at all in the figure until I drag the divider around with the mouse to resize the panes, and then it shows up like it should. Do you have any suggestions on how I could fix this?

I am using MATLAB 2011a, if it matters.

The name 'MousePressedCallback' is not an accessible property for an instance of class 'com.mathworks.hg.peer.utils.UIMJTree

Any Ideas how I can do this: i noticed that the jtree.getTree is also not present.
I just have the following.
jtree.getTreeSelectionListeners
Help will be appreciated

I’m not sure it’s an application bug. Before subimage I actually target both the figure and the axes by using “figure(handle); axes(axeshandle)”. I have not used gcf or gca at all. Thanks anyway,
best

It sounds like you have updated the GUI using gcf, gca, or direct plotting (via plot or image), without directly specifying the target container handle. Since you use hidden handles in your code, the function targets whatever GUI container that has a non-hidden handle was last made active. By setting the ShowHiddenProperties of the root you simply made all handles visible, but this merely hides the root cause of your problem, which is the fact that you have not directly specified the target handle. Once you do that, there will no longer be a need for setting ShowHiddenProperties.

In short, it’s an application bug, not a Matlab bug.
