I believe the answer to this question already exists several times online, but everything I tried failed.
I got in a GUI-figure the option to open an other GUI-figure. In the second GUI I got plots and the first one can update these plots. Therefore its interesting to know if the second GUI is already/still open when I activate the update.
but I get the same result no matter if figure2 is open or not.
Is there an other way to get this information? I think of eventlisteners: figurehasbeenopened, figurehasbeenclosed
Thanks for help.
