How can I reopen or re-run a GUI figure once I closed the window?

Hello,

I created a very simple GUI using GUIDE, every time I want to run it I go to the generated .m file and press the “Run” button in the editor. The problem is that if I close the GUI window, I am not able to reopen it. When I press “Run” again, I can see the right command on the “command window” but nothing happens, the GUI is not launched.

The only solution I have so far is to close MATLAB completely and then open my files again, but this is of course very annoying.

Do you have any suggestions?

Thanks for the help!

What happens if you instead run it from command line as e.g.

myGui = GUIName

where GUIName is obviously whatever you named your GUI.

Do you get an output on command line showing that myGUI is a figure? It is possible it is opening the figure off-screen though why it would do this only after closing it rather than always would be a mystery.

This is not normal behaviour. It sounds like there may be an infinite loop somewhere in your code. Does it say "busy" in the bottom left corner of the command window? If so, press CTRL+C to cancel any running code execution.

Marc,

Thanks for your answer. It does not say busy, anyway I tried the CTRL+C command but nothing changed. Do you have any other suggestion?

I don't have any idea of what it could be, but I can try and help you debug.

Create a new (dummy) GUI. It doesn't have to do much. Then run it by pressing "run" in the .m file and see if it causes the same issue. If it does, then we know it's a problem with your Matlab installation. If it doesn't, it has to be something to do with your GUI.

I have the same issue here... any ideas or help on this?

@Shae Morgan: Please open a new thread and explain the problem again. How do you close the figure? What do you observe, when you set a breakpoint in the OpeningFcn and start the M-file?
