Recording and saving a GUI experiment in Guide?

Hello ,

I would like to be recording and saving the screen each time i am doing an experiment in Guide (GUI). I do not how to start any information concerning that?

Should i create a new pushbutton? If yes, which callback should i use .

@Franck paulin Ludovig pehn Mayo - is there a particular part of the screen that you want to record/save? An axes? If the user starts the recording, how often do you expect to "take a picture" of the screen? Please provide more details.

@Geoff Hayes basically i would like to record/save what is happening in the "figure" when running the GUI. I would like to record the whole experiment that is taking place there.I have different set of experiments that is happening each time i click on a "Next" button.

I would like to record each set of experiments. They are all happening in the "Figures"

@Franck paulin Ludovig pehn Mayo - if you want to record what is happening in the figure and/or the whole experiment, then you would need to use a timer to periodically get a snapshot of what is happening on the figure, and then save it to a file either as an image or to update a video file. It might actually be easier to use third party software (maybe QuickTime) to record the screen session.

I understand you want to capture and save the screen while running a GUI created with GUIDE in MATLAB, for this you can create a new push button and use its callback to capture the screen. You can follow these steps for the same:

1. Create a New Push Button: Open your GUI in GUIDE, and from the "Tools" menu, select "Insert Standard Components" and then choose "Push Button." Place the button where you want it in your GUI.
2. Create Callback Function: In the Callback Editor, create a new callback function for the 'ButtonDownFcn' event. This function will be called when the button is pressed.
3. Capture and Save Screen Function: Now, you need to create the function captureAndSaveScreen that captures the screen and saves it. You can use the ‘getframe’ and ‘imwrite’ functions for this.
