To anybody attempting this in R2019b (and later?): unless you specify the image size, nothing will be shown!. A solution is presented in this answer

str = [''];

In reply to Sneha. You need to use findjobj, not findobj. Read the post (and the other articles on this blog) carefully.

In reply to Sneha. Hi Yair, Tried enlarging my image and added empty space on top of the image and this worked. Thank you for the help. I wanted to align my text and tried using the following lines

jButton = findobj(hObject);
jButton.setVerticalAlignment(javax.swing.SwingConstants.BOTTOM);
but got an error stating:
No appropriate method, property, or field 'setVerticalAlignment' for class 'matlab.ui.control.UIControl'.

Error in MSCT>pushbutton2_CreateFcn (line 812)
jButton.setVerticalAlignment(javax.swing.SwingConstants.BOTTOM);

Error in gui_mainfcn (line 95)
        feval(varargin{:});

Error in MSCT (line 44)
    gui_mainfcn(gui_State, varargin{:});

Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)MSCT('pushbutton2_CreateFcn',hObject,eventdata,guidata(hObject))

Can you please help me with this.

In reply to Sneha. @Sneha - either enlarge your image by adding empty space at the top, or use Java by accessing the button's underlying Java control and then calling setVerticalAlignment(javax.swing.SwingConstants.BOTTOM).

Hi Yair
I added image to my push button using the CData property but was not able to set its position.
The image added by me is positioned at the center of the button by default. Is there any way to change its position to bottom of the push button

In reply to Ronit. @Ronit - you can update the button's CData property. Read the Matlab documentation for the uicontrol function for details/examples.

Do you know a way to show images on push buttons via GUIDE?
Thanks in advance!

In reply to Klaus. @Klaus - not directly, but you can create a small image and add it to the button's CData. As long as you don't resize the button too much in either direction, this should work nicely.

Dear Yair,

thank you for the detailed description. Do you see a chance to put a 90 deg rotated text on a uicontrol (pushbutton)?

Best regars
