MATLAB: Replace buttons

deleteguipush button

Hello,
I have a function which creates buttons in my gui when I load data. The number of buttons depend on the size of the XTickLabels and YTickLabels. If I load some other data I want that the buttons from the first data disappear and are replaced by the new amount of buttons. Don't now how I can remove the buttons and how the function knows if there are buttons or not. Here is the code of the button-creation:
s = size(x,2);
breiteQuadrat = 625/s
for n=1:s
handles.b{n}=uicontrol('Style','PushButton','Units','pixels', 'Position',[125-breiteQuadrat/2-5+breiteQuadrat*n 40 10 10],'Visible','on','Callback',@(obj,event)msgbox(num2str(n),num2str(n)));
end
t = size(y,2);
hoeheQuadrat = 625/t
for n=1:t
handles.c{n}=uicontrol('Style','PushButton','Units','pixels', 'Position',[40 125-hoeheQuadrat/2-5+hoeheQuadrat*n 10 10],'Visible','on','Callback',@(obj,event)msgbox(num2str(n),num2str(n)));
end

Best Answer

To detect if the buttons are in the figure
all(cellfun(@ishandle,handles.b))
To remove all the buttons
delete(handles.b{:})
Also look at your previous question, if the answer is what you wanted (seems to be) please accept it.
