Button Callback - Matlab Issue

PinkLab — Thu, 22 Oct 2009 14:35:13 -0400

I am trying to create a callback on push button,

If radio1 is selected then run case 1
If radio2 is selected then run case 2
If radio3 is selected then run case 3

Any hint how to write this code??

Straight off of the top of my head (meaning there is probably a lot slicker ways of doing it)

1) Define yourself a handles variable say handles.Case_Select

2) In your radio1 button callback insert something like
handles.CaseSelect = 1;
% Update handles structure
guidata(hObject, handles);

3) In your radio2 button callback
handles.CaseSelect = 2;
% Update handles structure
guidata(hObject, handles);

etc.

Now your switch statement looks like
switch handles.CaseSelect
   case(1)
      --- do case1 things---
  case(2)
     ---do case2 things

end

Its rather crude, but should do what you want. If I think of a better idea, I will come back.

Have all three call the same callback:

function []=radio_callback(hObject,EventData,handles)

switch hObject
    case handles.radio1
        % run case 1
    case handles.radio2
        % run case 2
    case handles.radio3
        % run case 3
    otherwise
        % Whatever
end

If I understood right you want to implement a callback of a pushbutton.
That can mean the action occurs not by selecting a radio button?

In this case a variable like "handles.myCaseId" is a good solution.

If action shall occure by clicking a radio button AND they are exclusive, meaning activating one radio will deactivate the other(s), then a buttonGroupBox is the solution. In this case you can implement the selectionChanged-function of the buttonGroupBox.

Yes, you are right, i need callback in Button1 so when radio1 is selected do that task otherwise depending on which radio is selected do that particular task.... the task is to create a plot on axes so please help.........
