GUI Interface: Need advice on a few things

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

    %   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

    %   unrecognized property name or invalid value makes property application
    %   stop.  All inputs are passed to TestInterface_OpeningFcn via varargin.

I have no idea. You didn't attach the fig file so we can't run it and it's impossible to tell what it looks like just from the source code. But I would guess the answer is "Yes - there's a way to do it."

[Jan]

"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?
