Creating functional menu (guide)

Question

0 个投票

I created a menu using guide

and I created their callbacks

For the save, I have a matrix inside a uitable (also created using guide) that I want to export .. how can I program that?

For the reset, I need all edit boxes to be blank again.. how can I program that?

thanks

Here is the code I am working on

function varargout = LRT(varargin)
 
 
%LRT MATLAB code file for LRT.fig
%      LRT, by itself, creates a new LRT or raises the existing
%      singleton*.
%
%      H = LRT returns the handle to a new LRT or the handle to
%      the existing singleton*.
%
%      LRT('Property','Value',...) creates a new LRT using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to LRT_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      LRT('CALLBACK') and LRT('CALLBACK',hObject,...) call the
%      local function named CALLBACK in LRT.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

% See also: GUIDE, GUIDATA, GUIHANDLES

I need to get the reset and save to work.. but I can't find any help on that

Rik 2020-3-20

Isn't a reset just closing and opening your GUI? (unless you only want to empty some of your components, in which case you could either create a separate function that creates them, or a separate function that will clear the contents, whatever that means for your context) And what variable do you need to save?

I sugest you move away from GUIDE. As you have noticed it creates a wall of code that nobody wants to dig through, and you still need the fig file to run it properly.

This time I'll edit your code for you. Next time, please use the tools explained on this page to make your comments more readable.
