Select multiple radiobutton at the same time

I have a matlab gui that when it opens has 9 radiobutton i use this to be able to select only one at a time :

switch get(gcbo,'Tag')
case {'Norme0','Norme1022'}
 set(gcbo,'Value',1)
case 'NormeEm'
 set(gcbo,'Value',1),enable(hno(3))
case 'NormeG53'
 set(gcbo,'Value',1),enable(hno(4))
case 'NormeCh'
 set(gcbo,'Value',1),enable(hno(5))
case 'NormeUsrV'
 set(gcbo,'Value',1),enable(hno(6))
case 'NormeUsrI'
 set(gcbo,'Value',1),enable(hno(7))
case 'Norme50160'
 set(gcbo,'Value',1),enable(hno(8))
case {'Norme519','Param519-1'}
 set(hrb(9),'Value',1)
 end

for each case we can select one radiobutton and if we select another it will deselect the one that was selected.

Now i would like if one is selected to be able to select another one if i am on a specific radiobutton

switch get(gcbo,'Tag')
 case {'Norme0','Norme1022'}
 set(gcbo,'Value',1)
case 'NormeEm'
 set(gcbo,'Value',1),enable(hno(3))
 if get(gcbo,'Value') ==1
     switch get(gcbo,'Tag')
     case 'Norme1022'
      set(gcbo,'Value',1)
     case 'NormeUsrV'
      set(gcbo,'Value',1),enable(hno(6))
     case 'Norme50160'
      set(gcbo,'Value',1),enable(hno(8))
     end
 end
case 'NormeG53'
 set(gcbo,'Value',1),enable(hno(4))
case 'NormeCh'
 set(gcbo,'Value',1),enable(hno(5))
case 'NormeUsrV'
 set(gcbo,'Value',1),enable(hno(6))
case 'NormeUsrI'
 set(gcbo,'Value',1),enable(hno(7))
case 'Norme50160'
 set(gcbo,'Value',1),enable(hno(8))
case {'Norme519','Param519-1'}
 set(hrb(9),'Value',1),Scr519(hno(9:12))
end

but when launch it it won't work if anyone could help me on this.

Please mention, what "it won't work" means.

It is the natur of radio buttons, that only one of a group is selected. If you want to allow multiple selections, use check boxes.

[Walter Roberson]

If they are in a uibuttongroup then only one can be active, and that is enforced by the container.

[Ali]

ok i will try with checkboxes because when i say it won't work it means that i can still only select one and not two

[Walter Roberson]

The problem is not radio button, it is the fact that you are controlling them by a button container. The exact same thing happens with checkboxes if you put them in a uibuttongroup

[Ali]

I didn't put them in a uibuttongroup they are just all in the same figure that's all. But even with checkboxes it still doesn't work.

[dpb]

Think it'll take a minimum working example here to figure out just what the gui is for anybody to try to reproduce/debug. Only 2 or 3 is as good as 20...

[Ali]

Here is an exemple we have the gui which is exemple one which posses 3 checkboxes and the other function exemple2 which run the gui and what i want it to do is if UsrV is selected UsrI can't be selected and i want IEEE519 to be checkable at all times so that i select at least two checkboxes at all time. But on this exemple i get the following error

SWITCH expression must be a scalar or string constant.

Error in exemple2 (line 11)
switch get(gcbo,'Tag');

Hi Ali,

use uipanel() for the checkboxes and uibuttongroup() for the radiobuttons:

myGUI;

Kind regards,

[Ali]

thank you i will try that

[Ali]

I tried to set up two uipanels so that i can only select one checkbox in each of one but when i put them in place when i launch my programm matlab gives me this code error :

??? Warning: Struct field assignment overwrites a value with class "double".
 See MATLAB 7.0.4 Release Notes, Assigning Nonstructure Variables As Structures Displays Warning for details.

ligne 17 of kgexec4n is

   hf=kgui4n;

ligne 133 of kgui4n is

   h0.c=uipanel('Unit','Pixels')

with h0 being my figure

and ligne 247 of kgui4n is :

   ho.t=uipanel('Unit','Pixels')

[Robert U]

You should not assign the handle of uipanel to the figure handle. I use "gui" as structure array to collect and organize handles of different graphical objects.

[Ali]

ok thx for the answer

Answer 2

[Walter Roberson]

hf=exemple;

You run the code in exemple and it returns. You are no longer running any code inside exemple but it set up several graphics objects that are sitting around displaying things or waiting for something to happen.

switch get(gcbo,'Tag');  %l'objet ayant provoqué l'appel

gcbo is the current callback object. You are not executing a callback, so gcbo will be empty.

In order to use that switch statement you would need to configure several controls with the same callback function, and the code would need to be inside that callback. (In which case you should probably use the handle automatically passed in as the first parameter of the callback instead of gcbo)

[Ali]

The problem came from the exemple i gave, in the program i use i have no problems with this line as i have differents checkboxes and pushbutton having the same callback function which is kgexec4n
