How do I set the getkey figure as invisible?

I'm using getkey to record responses to stimuli, but it currently pops up in the bottom corner which creates a distraction. I'm new to matlab and I've had a play around with the figure settings but haven't been able to stop it from appearing.

The code for the figure window is:

% Set up the figure
% May be the position property should be individually tweaked to avoid visibility
fh = figure('keypressfcn',callstr, ... 'windowstyle','modal',... 'position',[0 -40 1 1],... 'Name','GETKEY', ... 'userdata','timeout') ;

The full code is available here: https://uk.mathworks.com/matlabcentral/fileexchange/7465-getkey

Any help would be really appreciated! Thanks.

What is the actual problem you want to solve? What does "record repsonses to stimuli" exactly mean?

Dear LJM,

I am the author of this function. Unfortunately you cannot hide the figure completely as it requires to be modal. However, if you have created your own figure and want to use GETKEY, you can incorporate the code of my function into your own figure to receive key presses.

Take care, Jos

Hi, I'm creating a speed control for a car for my final degree project and I'm using the getkeywait (extremely useful btw) inside a for loop. The trouble I have is that it keeps opening and closing its own figure delaying the simulation. At the end of the loop i use a subplot (2,2,p) to create a figure with different variables (instant speed vs time, gravity acceleration vs time, etc). Is it possible to add the annoying getkeywait figure inside the subplot so that it won't delay the simulation opening and closing its own figure?

Thanks in advance and congrats for your amazing work,

Ricardo
