matlabgui按钮组怎么设置(MATLABGUI设计)

Gui中添加图标,能很大程度上提高用户的友好度,显得格外舒适。

MATLAB 官方并没有提供向菜单栏中添加图标的直接方法,基于figure设计的GUI中,可以通过JaveFrame属性间接设置图标。基于uifigure设计的GUI目前还没有间接的方法,相信后续版本会解决这个问题吧。

今天介绍一个在Matlab File Exchange/Github上公开的很实用的工具: setMenuIcon,我们可以很方便的向菜单选项中添加图标了。

以下为核心源码:

function setMenuIcon(menuObject,iconFile) % SETMENUICON Add icons to UIMENU items. % SETMENUICON(MENUOBJECT,ICONFILE) sets the icon of MENUOBJECT to % ICONFILE. MENUOBJECT is a menu item created with MATLAB's own UIMENU. % ICONFILE denotes the path to an image file containing the desired icon. % This should work with GIF, JPEG and PNG images. % Copyright (C) 2020 Florian Rau % % setMenuIcon is free software: you can redistribute it and/or modify it % under the terms of the GNU General Public License as published by the % Free Software Foundation, either version 3 of the License, or (at your % option) any later version. % % setMenuIcon is distributed in the hope that it will be useful, but % WITHOUT ANY WARRANTY; without even the implied warranty of % MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU % General Public License for more details. % % You should have received a copy of the GNU General Public License along % with setMenuIcon.

示例代码:

效果如下:
