@Jan – undecorate only works with legacy (Java-based) figures, not the new App-designer-created uifigures (which use a completely different technology).

My idea was to include the undecorate.m file in the start up function but it produces the following error:

Cannot undecorate a docked figure.

Note that I am not too familiar with handling MATLAB figures so this might be easy to fix but I just don’t know how.

Regards, Jan

@David – you will need to do this programmatically: this is typically handled by the window frame but without the frame it doesn’t happen automatically. So trap a mouse click event and then move the figure as per subsequent mouse-movement events.

Is it possible to grab and drag a ‘frameless’ figure without the title bar? I would like to click somewhere in the frameless figure area, and drag it around.

Kind regards

I remembered that this issue was discussed in your blog before. I must’ve hidden the warning in the past…

I started seeing the following warning when trying to access the JavaFrame property:

Warning: figure JavaFrame property will be obsoleted in a future release. For more information see the JavaFrame resource on the MathWorks web site.

I might be mistaken here, but I don’t think I saw this before R2015a. Should we be worried?

I mainly use it to maximize figures, as per your tip from long ago, and did not look into new methods since the introduction of HG2. Is there another way to maximize figures now without getting warnings?

Thanks!

I’ve tried both the code above and the functions you submitted. I’ve got 2 areas of feedback:

1. The figure sizing isn’t quite correct. It was a bit large and I had to remove the “+mjr.getY” term to get it to fit properly.
2. There are focus traversal problems with the current function. When I use it, I’m unable to input any text or use any of the UI elements inside as the focus keeps transferring elsewhere before any text can be input.

On a side note, I’m using this to generate a popup menu inside of another GUI. It works pretty well, and I don’t think it would be too much work to clean it up. I think it would do well as a MATLAB file submission if labeled as a ‘popup’ menu template.

By the way, I’m using 2014a.

@Yair – Thank you for your speedy response. I have tired your suggestion, but it doesn’t work,and remains the previous status, 20 pixels isn’t increased, I don’t why.

@Cheung – you can increase the figure’s height by 20 pixels to take into account the titlebar (i.e., screen(4)+20).

As for your OK button, you should review how to specify Matlab callbacks.

% the function can display two images. when the 'OK' button is pressed, the second image would appear.  
function display_img 
   screen = get(0,'ScreenSize');
   H1=figure('menubar','none');
   set(H1,'Position',[0, 0, screen(3),screen(4)]);
   img1 = imread('peppers.png'); 
   subplot(1,2,1);
   subimage(img1);
   axis off;
   H2 = uicontrol('Style','pushbutton','String','OK','Position',[200,100,100,40],'Fontsize',12);
   set(H2,'callback','my_callbacks');
   jFrame = undecorateFig(H1);

function my_callbacks
   img2 = imread('peppers.png'); 
   subplot(1,2,2);
   subimage(img2);
   axis off;

However, after I use ‘undecorateFig’ tool, the ‘OK’ button doesn’t work .

Best regards!
