Thank Joan You may find my Java-based data table utility (on the Matlab File Exchange) useful as a general-purpose sortable Java table. My PlotData utility also uses a Java table, in this case to display the raw data of figure plots. With the knowledge that you have displayed in your question, it should be fairly easy for you to modify the code in these two utilities to fit your purposes.

First of all, congratulations for your excellent site.
I looked for a place where to post this idea, but I didn’t know where to.
I do not like Matlab uitable, and in GUI I use the java table. However, java table is difficult for me to program, specially the Callbacks when someone edits a cell value. Is there a way I could use the table in the ArrayEditor to edit data from a GUI?. The table in the ArrayEditor looks like the java table, and has many features when right-click, and also updates the value of the matrix when I edit a cell value. My idea is to have a button in my main GUI that says “Edit”. When clicked, it opens the ArrayEditor in a separate window. This window should also have buttons Accept, Cancel. In Accept, it collects the data from the ArrayEditor and closes window. When cancel, it simply closes the windows. To put it in a nutshell… is there a way to put the ArrayEditor table in a new figure window, with room left for adding buttons? (I can do all the rest). Thank you very much and congratulations again.

@wei – I believe (not sure) that the dotted line is OS-generated. I do not know of a way to control it with PLAF – you may need to hack some really internal Java/OS function for this…

If you don’t wish the control selection to become visible, perhaps you should simply set the control to be non-focusable or disabled?

@Yair, Thank you for the help. I tried and it worked with second command below:

jButton.setBorder('empty'); %no visible effect
jButton.setBorder([]);

Another (plaf?) question: after a jbutton is pressed, there is a dotted rectangular line on the button icon indicating the latest focused object. Could this line be removed or set to the same background color so it is invisible?

My uicomponent utility (and similarly Matlab’s javacomponent function) returns the Java reference. This can be used to update the component’s Border property. The default component border is set at creation-time based on the currently-active Look-and-Feel (L&F), but can always be overridden. You can’t pre-lock a property value. But you can modify it immediately following creation, which is essentially the same thing.

Alternately, you can create your component with some specific predefined L&F, regardless of the system’s L&F, as follows:

import javax.swing.UIManager;
originalLnF = UIManager.getLookAndFeel;
UIManager.setLookAndFeel('javax.swing.plaf.metal.MetalLookAndFeel');
   % Create your GUI here...
UIManager.setLookAndFeel(originalLnF);

Here are two official documentation references for the Java L&F system:

@Yair,
I’m using your uicomponent for such button. there is java component border which, depending on desktop’s appearance, is either com.sun.java.swing.plaf.windows.XPStyle$XPEmptyBorder or javax.swing.plaf.BorderUIResource$CompoundBorderUIResource

Not sure how to proceed to lock onto one style or the other.

@Wei – First you need to get the underlying Java handle of the Matlab uicomponent (this is done using my FindJObj utility on the File Exchange). Then set the java handle’s Border property as explained here: http://java.sun.com/docs/books/tutorial/uiswing/components/border.html
Some useful examples: http://www.java2s.com/Code/Java/Swing-JFC/Border.htm

Yair,
This is about uicomponent (e.g. JButton). How does one set button’s Border property so button’s appearance is isolated from PC desktop appearance Windows XP vs. Classic styles?
