Hi Yair,

Sorting of numeric values in UITable is not working . Any workaround or fix?

In reply to Eddie. @Eddie - try to download the latest version of findjobj and then try again, it works well on all Matlab versions, including 18a and 18b.

I just downloaded 2018b and findjobj does not work on uicontrol anymore 🙁

For example,
u=uicontrol;
jobj=findjobj(u);

Returns an empty handle in 2018b, but in 2018a that is not a problem.

In reply to Omar. Omar - findjobj is not a built-in Matlab function, it is a function that you need to download from the Matlab File Exchange, as the article clearly states (read it!)...

Hello Yair,

I am using MATLAB R2017a and I get an “Undefined function or variable ‘findjobj’.”-Error when using findjobj(text). findobj(text) works tho.
Is this no longer supported?

Hi Yair,
Just in case you don’t know, Matlab Central web update likely breaks pattern search in checkVersion(). I use the similar method to your code, and realized this problem.
My current solution is to search ‘user_version’, which seems reliable.

Hello,

Hope you are doing fine. I have went through the document for customizing the border.
Let me rephrase again to have we both on the same page, I need your help in understanding how to override the default Push Button border properties in java and refer the same in Matlab (need to override the default border function).

I am quite new to MATLAB and don’t know how these two languages are exchanging their objects. I would really appreciate if you provide me the more details.

Thanks for your time and support as always! 🙂

In reply to Akshay. @Ashkay - did you bother to read what I just sent you? You need to read the material and then search online to see how to create a rounded Java Border.

In reply to Akshay. Hi, Ok. Can I customize default square pushbutton to have circular border?

In reply to Akshay.

findjobj can be used to find the underlying Java control of an existing Matlab GUI control (e.g., pushbutton). You can then modify the control’s Border as explained here: http://undocumentedmatlab.com/blog/customizing-uicontrol-border
