It helps a lot. Thank you !
Does it work in MATLAB Compiler ? I do not see a reason why it should not but I would like to have your confirmation.

In reply to Mhyd. @Mhyd - simple: Google "java border" and the very first search result is Java's official tutorial on how to use Java borders, and this includes a short discussion of various predefined border styles, including LineBorder which is the simplest border.

Hi Yair, Thanks for sharing this info. I was wondering how would one potentially remember these commands :

jNewBorder = javax.swing.border.LineBorder(jColor, 1, true);  % red, 1px, rounded=true
jPanel.getBorder.setBorder(jNewBorder);

as in how would one know to look specifically into javax.swing.border.LineBorder to create the new java border.. seems a long name to commit to memory

In reply to lsh. @LSH - this is probably an EDT timing issue. Add a call to drawnow before requesting the PrintableComponent.

Hi Yair,

I found that when I invoke jpanel.JavaFrame.getPrintableComponent in my script, it will return something like this:
com.mathworks.hg.peer.ui.UIPanelPeer$UIPanelJPanel[,0,0,0x0,invalid,layout=...]

However when I invoke this in the command window, it will return normal value:
com.mathworks.hg.peer.ui.UIPanelPeer$UIPanelJPanel[,0,0,300x300,layout=...]

Why does this happen?
I was using MATLAB 2014b.

I have experienced the same problem with position values getting reset for controls within panels. I believe that this does not happen if the figure is changed to be non-resizable.

@Tom – …or to hire a professional Matlab expert to do it for you… 🙂

I have found that GUIDE graphics are impossibly broken in 2014b. In the guide designer, controls disappear and cannot be made to reappear only with great effort and luck. In addition, controls with normalized units sometimes have their position values reset to all zeros or to 0 and 1.

The only workaround I have gotten from Mathworks is to convert to a programmatic interface.

In reply to Julien. @Julien - I assume this is done for performance reasons, graphics being drawn by native C code. However I don't know this for a fact.

Thanks… I was dreaming to a world where axes would have their own containers so that they could be added to any Java container, or could be scrolled.
So, there are still 2 overlayed content panes, one for uicontrols and uipanels and another for graphics (actually 2, depending on renderer). Do you have an idea of the reason why graphics is drawn like this at the canvas level ?
