Hello there,
I have the below test GUI .m file which takes three user inputs, outputs 1 value, and graphs a surface.
Here's where I need help:
1) Is there a way to remove/replace the matlab logo in the top left of the window of this GUI program?
2) Is there a way to make the blue textbox uneditable and still maintain its blue color? I tried disabling it, but that grays it out and I want to keep its blue color.
3) Is there a way to mark a point on the surface for the given user input values for X and Y? So I want to put a red dot at the X,Y from the user and have a tiny textbox next to it which says "X = this, Y = this, Z = this".
I hope I am not asking for too much.
Thank you
function varargout = TestInterface(varargin)
% TESTINTERFACE Application M-file for TestInterface.fig
% TESTINTERFACE, by itself, creates a new TESTINTERFACE or raises the existing
% singleton*.
%
% H = TESTINTERFACE returns the handle to a new TESTINTERFACE or the handle to
% the existing singleton*.
%
% TESTINTERFACE('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in TESTINTERFACE.M with the given input arguments.
%
% TESTINTERFACE('Property','Value',...) creates a new TESTINTERFACE or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before two_axes_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to TestInterface_OpeningFcn via varargin.
%
% *See GUI Options - GUI allows only one instance to run (singleton).

"I tried disabling it" is not unique. Please post the code, because it matters if you set 'Enable' to 'off' or to 'inactive'.

Sorry about that. I have fixed these issues. Thank you.

With regards to the Mathworks logo: No, it is a violation of license to replace the logo in an interactive MATLAB session. If you are compiling using MATLAB Compiler then deploytool has an option to put in a different image.

Thank you. Is deploytool part of the MatLab compiler or is it something separate I need to download?
