Hello, I have noticed when I open up an old matlab GUI (created using GUIDE) from back in 2015, some of the components are missing near the top of the figure.

I noticed that their y-position has somehow changed to be > 1 as shown below (1.16). Is there a way to correct & stop this?

n

Thanks

Jason

i wonder what causes them to have a normalised position > 1. Back in 2015 it was fine . All ive done is upgraded to the latest version of matlab and changed my pc (and screen)

Before opening the hood, I'd open the GUI in matlab 2015 again (if possible) to confirm that this is a problem with the matlab version. I'd also confirm that the units are normalized. Sometimes merely closing and restarting matlab will fix these quirks. You mentioned that the screen was affected too which suggests a bigger problem.

This solution is based on Rik Wisselink's suggestion in the comments under the quesiton.

The idea is to find objects within the GUI whose positions are outside of the GUI frame. The code below should be run from within the GUI within any callback function or at the end of the initializer function and requires the 'handles' vector which is a structure listing all handles within the GUI.

handleVec = struct2array(handles);       %handles is the handles structure
positions = get(handleVec, 'Position'); 
xPos = cellfun(@(x)x(1), positions); 
yPos = cellfun(@(x)x(2), positions); 
isout = xPos > 0.99 | yPos > 0.99;
handleVec(isout)                        %this lists all handles outside of the GUI frame

The next step depends on how many objects you have to move. If it's just a few, it might be best to just get the names of each object and then make the adjustments from within guide. If there are lots of objects, you'll need to manually place each of them from within the initializer function.
