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.

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...

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;
function myGUI(~)
gui.fh = figure;
% button group 1 with entry window
gui.btnGrp1.fh = uibuttongroup('Visible','off',...
'Unit','Pixels',...
'Position',[10 10 120 160 ],...
'SelectionChangedFcn',@buttonSelection);
gui.btnGrp1.btn(1).fh = uicontrol(gui.btnGrp1.fh,...
'Style','radiobutton',...
'String','button 1',...
'Visible', 'on',...
'Position',[10 75 100 30]);
gui.btnGrp1.btn(2).fh = uicontrol(gui.btnGrp1.fh,...
'Style','radiobutton',...
'String','button 2',...
'Position',[10 50 100 30]);
gui.btnGrp1.edit.fh = uicontrol(gui.btnGrp1.fh,...
'Style','edit',...
'String','Entry',...
'Position',[10 25 100 30]);
gui.btnGrp1.fh.Visible = 'on';
% button group 2 with entry window
gui.btnGrp2.fh = uibuttongroup('Visible','off',...
'Unit','Pixels',...
'Position',gui.btnGrp1.fh.Position + [ gui.btnGrp1.fh.Position(3)+10 0 0 0],...
'SelectionChangedFcn',@buttonSelection);
gui.btnGrp2.btn(1).fh = uicontrol(gui.btnGrp2.fh,...
'Style','radiobutton',...
'String','button 3',...
'Visible', 'on',...
'Position',[10 75 100 30]);
gui.btnGrp2.btn(2).fh = uicontrol(gui.btnGrp2.fh,...
'Style','radiobutton',...
'String','button 4',...
'Position',[10 50 100 30]);
gui.btnGrp2.edit.fh = uicontrol(gui.btnGrp2.fh,...
'Style','edit',...
'String','Entry',...
'Position',[10 25 100 30]);
gui.btnGrp2.fh.Visible = 'on';
drawnow();
% checkbox group 1 with entry window
gui.chkPanel.fh = uipanel('Unit','Pixels',...
'Position',gui.btnGrp2.fh.Position + [ gui.btnGrp2.fh.Position(3)+10 0 0 0]);
gui.chkBGrp2.btn(1).fh = uicontrol(gui.chkPanel.fh,...
'Style','checkbox',...
'String','checkbox 1',...
'Visible', 'on',...
'Position',[10 75 100 30]);
gui.chkBGrp2.btn(2).fh = uicontrol(gui.chkPanel.fh,...
'Style','checkbox',...
'String','checkbox 2',...
'Position',[10 50 100 30]);
gui.chkBGrp2.edit.fh = uicontrol(gui.chkPanel.fh,...
'Style','edit',...
'String','Entry',...
'Position',[10 25 100 30]);
gui.chkBGrp2.fh.Visible = 'on';
drawnow();
resize();
set(gui.fh,'ResizeFcn',@resize);
function resize(~,~)
% Set all units to normalized
set( findall(gui.fh ,'Units','pixels'),'Units','normalized');
set( findall(gui.fh ,'FontUnits','points'),'FontUnits','normalized');
end
function buttonSelection( ~, event )
disp(['Previous: ' event.OldValue.String]);
disp(['Current: ' event.NewValue.String]);
end
end
Kind regards,
Robert

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.

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)

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
