如何通过功能单选按钮，在MATLAB使用指南创建一个按钮组中？ [英] How to pass function to radio button in a button group created using guide in MATLAB?

问题描述

我创建四个单选按钮和使用指南一个按钮一个按钮组。

有四个功能，一个用于分别写入每个单选按钮。

1. 如何从各自的单选按钮调用这些功能。


2. 当一个按钮为pressed，与活动单选按钮应该执行相关的功能。

解决方案

：一种为按钮组回调的解决方案：SelectionChangeFCN

使用的选择更改的回调属性（右键点击按钮组，选择的查看Callbacks-> SelectionChangeFcn 的）的 uipanel 。在 EVENTDATA 的参数包含手柄pviously选择单选按钮当前和$ P $。在 EVENTDATA 的参数是具有以下字段的结构：

• 事件名称


• 的OldValue


• 的NewValue

因此​​，根据 eventdata.NewValue 的值;例如：

 函数uipanel1_SelectionChangeFcn（hObject，EVENTDATA，把手）
...
newButton = GET（eventdata.NewValue，'标签'）;
切换newButton
     案radiobutton1
         ％code为1单选框这里
     案radiobutton2
         ％code为单选2在这里
     ...
结束
...
 

一种按钮回调的解决方案

回调您的按钮的可能沿东西线

 函数button1_Callback（hObject，EVENTDATA，把手）
h_selectedRadioButton = GET（handles.uipanel1，'SelectedObject'）;
selectedRadioTag = GET（h_selectedRadioButton，'标签'）
切换selectedRadioTag
   案radiobutton1   案radiobutton2
   ...
结束
 

我也请您看看MATLAB文档的详细信息，处理图形和建筑图形用户界面。

I have created a button group with four radio buttons and a push button using guide.

There are four functions, one for each radio button written separately.

1. How do you to call these functions from respective radio buttons.
2. When a push button is pressed, the function associated with the active radio button should execute.

解决方案

A solution for the Button Group Callback: SelectionChangeFCN

Use the Selection Change callback property (right click on the Button Group and select View Callbacks->SelectionChangeFcn) of the uipanel. The eventdata argument contains the handles to the current and previously selected radiobutton. The eventdata argument is a structure with the following fields:

• EventName
• OldValue
• NewValue

So, depending on the value of eventdata.NewValue; for example

function uipanel1_SelectionChangeFcn(hObject,eventdata,handles)
...
newButton=get(eventdata.NewValue,'tag');
switch newButton
     case 'radiobutton1'
         % code for radiobutton 1 here
     case 'radiobutton2'
         % code for radiobutton 2 here
     ...
end
...

A solution for the push button callback

The callback for your push button could have something along the lines of

function button1_Callback(hObject,eventdata,handles)
h_selectedRadioButton = get(handles.uipanel1,'SelectedObject');
selectedRadioTag = get(h_selectedRadioButton,'tag')
switch selectedRadioTag
   case 'radiobutton1'

   case 'radiobutton2'
   ...
end

I also refer you to the MATLAB documentation for more information on Handle Graphics and building graphical user interfaces.
