mfile中带工具栏的MatlabGUI

我正在构建一个MatlabGUI，它允许用户使用一些交互式工具进行图像处理（一个没有fig文件的mfile），
类似于使用

imrotate

和角度参数旋转图像，以及使用

bwareaopen

和区域参数清除像素

起初，我想用我的mfile绘制工具，比如

function myGUI( grayI )

h_fig = figure;
h_ax = imshow( grayI );
title('Drag line and press button to rotate image');

ImgSize = size(grayI);
h_lev = imline(gca, [ 0.2*ImgSize(2), 0.1*ImgSize(1); ...
0.8*ImgSize(2) 0.1*ImgSize(1) ] );
h_lev.addNewPositionCallback( @LineUpdateFcn );

% text for the angle
h_txt = uicontrol('Style','text','String','Angle = []', 'unit', 'norm', ...
'pos',[0 0.9 .1 .05]);

%add rotate button
h_btn = uicontrol('unit','norm','pos',[0 0.95 .1 .05]);
set(h_btn,'string','Rotate','callback',@RotateImageWithLever);

% save the elements data in figure
setappdata(h_fig,'h_lev',h_lev);
setappdata(h_fig,'h_ax',h_ax);
setappdata(h_fig,'h_txt',h_txt);

% wait for user to close figure
waitfor( h_fig );

但后来，我在中遇到了工具栏作为内置类的设计，并认为可能我缺少了使用类和内置

uitoolbar

命令设计工具栏的正确而简洁的方法

关于从单个mfile设计我的工具栏的任何建议？

对于您描述的工具，使用自定义工具栏可能是一个很好的解决方案。分别使用和创建工具栏和添加按钮或切换按钮。这可以在GUI m文件的初始化阶段轻松完成

下面我给出了一个简单的例子。一些警告：

切换按钮与按钮的逻辑未正确实现，因为反转图像、翻转图像然后再次反转将不会给出正确的结果。然而，我只是想展示如何对工具栏按钮进行编码，而不是如何处理图像

您可能希望使用比我在CData属性中提供的更具创造性的图标

尽管有我的过程示例，我还是鼓励使用面向对象的方法来解决这个问题

这是：

function myGUI(grayI)

persistent grayICopy;

%# Keep a persistent copy of the image data to be used in the toolbar tool
%# callbacks. Other possibilities here are to not store this data
%# persistently and instead read it from the plotted values or restructure
%# this whole code as a class and store the raw image data in a class
%# property.
grayICopy = grayI;

%# Create the figure window and show the image.
hFigure = figure;
hAxes = axes('Parent', hFigure);
image(grayI, 'Parent', hAxes); %# I don't have the Image processing Toolbox

%# Create toolbar
hToolbar = uitoolbar('Parent', hFigure);

%# Add a toolbar button for 90deg clockwise rotation
uipushtool('Parent', hToolbar, ...
    'ClickedCallback', @flipVertical, ...
    'CData', ...
