Guidata not updating handles

08-Nov-2019 04:42

This is only a test, I want to do some stuff and then send the result to the static test.When I run the GUI and click on the image, the image closes, the GUI closes, then the GUI open again and appears 'Has clicado en la imagen' in the statictext, but the video is closed.I do see your tests against handles.port_stt which suggest that you might be doing so (if you do have something going on in the background like that, you need to worry that it is maximizing your figure).If you do have a control that is determining the state of port_stt then it might make sense to fetch the updated guidata, but it would be more efficient to make the state a property of a control and only check the property (even if it is a User Data property): every time you fetch guidata() you are fetching all of the structure.Imagine if you had to input text commands to operate your web browser (yes, your web browser is a GUI too! This tutorial is written for those with little or no experience creating a MATLAB GUI (Graphical User Interface).Basic knowledge of MATLAB is not required, but recommended.Bytes Available); disp(a) lastcommand = sprintf('Recieved a message from robot: %s', char(data)); append_commandlog(h Object, handles, lastcommand) guidata(h Object, handles); when a tcpip, serial, or similar object triggers a callback in Matlab the first argument passed is always the handle to the communication object.

For the purposes of this tutorial, we are primarily concerned only with the MATLAB GUI Tutorial - Slider MATLAB GUI Tutorial - Pop-up Menu MATLAB GUI Tutorial - Plotting Data to Axes MATLAB GUI Tutorial - Button Types and Button Group MATLAB GUI Tutorial - A Brief Introduction to handles MATLAB GUI Tutorial - Sharing Data among Callbacks and Sub Functions Video Tutorial: GUIDE Basics More GUI Tutorial Videos From Doug Hull This is the end of the tutorial.Instead, you should use the handles structure for its namesakes (grpahics and object handles) only and then use either getappdata and setappdata or else some Object. The appdata approach lets you set however many variables of whatever type you want to any object that you want, and it is more efficient and responsive than the handles structure since you can query and set one thing at a time.The User Data approach only allows storage of a single variable, but it can be a struct (like handles) or cell array... Bytes Available Fcn, ); %have also tried handles.socket.Bytes Available); disp(a) lastcommand = sprintf('Recieved a message from robot: %s', char(data)); append_commandlog(h Object, handles, lastcommand) guidata(h Object, handles); I know this question is a little old but just in case it is still troubling you or for anyone else who comes across it, I will answer it anyways.

Looking past the errors in the code, I would advise not using handles for storing or passing anything that is either large or frequently changing.
