  • How can I get the texts, that i have created in the function handles to the function checkboxValue. I want to delete them in the second function. The two functions are not in the same script? Thanks
function handles = plotCAT(vaargin)
text(data(ObstPedestFlag, 1)- 0.5, data(ObstPedestFlag, 2) + 0.5, cellstr('PED-TP'));
text(data(ObstMovInvFlag, 1)- 0.5, data(ObstMovInvFlag, 2) + 0.5, cellstr('INV-TP'));
text(data(ObstStatFlag, 1)- 0.5, data(ObstStatFlag, 2) + 0.5, cellstr('STAT-TP'));
text(data(ObstMovFlag, 1)- 0.5, data(ObstMovFlag, 2) + 0.5, cellstr('MOV-TP'));
end
function checkboxValue= enter_call(hObject, eventdata, handles)
handles = guidata(hObject);
handles.checkboxValue= cell2mat(get(handles.h_checkbox, 'Value'));
handles.checkboxValue
guidata(hObject,handles);
close(gcf)
end

Store their handles in a variable and pass it as output from the first function and input to the second. Alternatively you could use findobj in the second function to grab their handles. If you prefer the latter, then I would set a 'tag' on all the objects that you want to delete, so that you can use:
% First function
text(x,y,'mytext','tag','mytag')
% Second function
delete(findobj(groot,'tag','mytag'))

"I have tried your solution but it showed me an error"
What I wrote was a comment to jonas, it was not a complete answer to your question.
To use it you would still need to pass the variable c from one function to the other. Three hours ago I gave you links that explain how to pass data from one function to another:

Read those links. If you are sensibly writing your own GUI then I recommend using nested functions. If you are unfortunately using GUIDE, then use guidata.

Oh, thanks Stephan! I missed your message to read. I am going to read the links.
