MATLAB to write a simple Gui__gui

As a convenient and easy to use tool, MATLAB is often used to show the results of related projects.

This blog explains how to create a simple GUI

First, start Matlab, enter guide in the command Window

Select the Blank GUI in the pop-up window

In the window that pops up, the left side is the toolbar, which you can drag

On the right is the display interface

Describes the following three features for this secondary use:

Left-click to edit Text,

Change the caption of the button and editable text as shown in the picture

Then the button event response edit, double-click the button, which is the selected picture in the above image

Click the icon shown in the above image to edit the event response.

The function pushbutton1_callback is found in the subsequent. m file.

Add the following below it

function Pushbutton1_callback (hobject, EventData, handles)
axis  off%% axis display
%%filename store open file name  Pathname Store path percent
% For example open F:\data\1.jpg
%%filename=1.jpg pathname=f:\data\
[filename pathname] =uigetfile ({' *.jpg '; ' *.bmp '; ' *.* '}, ' open picture ');
%-percent string splicing assembly path in the above example said at this time srt=f:\data\1.jpg
str=[pathname filename];
%% Open Image
Im=imread (str);
%% open Axes1 handle for axes1 operation
axes (handles.axes1);
Percent% in axes1 display image
imshow (IM);
path1= ' F:\result\ ';
Percent% in Axes2 display results Image results folder
%% When original image is F:\data\1.jpg percent
% This time axes2 will show F:\result\1.jpg
str1=[path1 FileName]
im1=imread (str1);
Axes (handles.axes2);
Imshow (IM1);

As shown in the figure

Then run the GUI

After execution, as shown in the figure

Click to select a picture to select the image can

Axes event editing like button editing
