Thread Subject: problem with selection in GUI

We are currently using a 'selectdata' function in our GUI program.
We want to use pushbutton to activate the function to select points from a
axes.But after we clicked the button,it said "error in figure:requested figure
handle use in another object".
Can anyone tell us what may be the problem?
Cheers

can you post the line of code where you call the figure function? you very probably have the same error as the following:

Hello qooroo,
actually we saw that thread and use what he said and added that.
This is the lines of code we add to the pushbutton call back:

function start_select_Callback(hObject, eventdata, handles)
% hObject handle to start_select (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)

figure(get(handles.strikrplot,'parent'))
[pl,x,y] = selectdata('selectionmode','Closest','Label','on');

we want to select point from axes strikeplot

but it still said:
??? Error using ==> figure
Requested figure handle in use by another object

Error in ==> selectdata at 299
figure(fighandle)

Error in ==> test1>start_select_Callback at 907
[pl,x,y] = selectdata('selectionmode','Closest','Label','on');

Error in ==> gui_mainfcn at 96
        feval(varargin{:});

Error in ==> test1 at 42
    gui_mainfcn(gui_State, varargin{:});

Error in ==>
@(hObject,eventdata)test1('start_select_Callback',hObject,eventdata,guidata(hObject))


??? Error while evaluating uicontrol Callback

I have exactly the same problem and i've tried the same things. Any solution?

A hunch: your GUI figure window was created but left in an interim hidden state. Then when you rerun, it complains that the figure already exists or something similar. To fix this, type the following in the command Window

close all

Now rerun your GUI and everything should be ok

with GUI with many axes defined in the display you can use function like :

plot( handles.axes1, bla bla bla )

and it will select the right display zone. but for function not accepting handle like image() you must use something to select it. something like

figure( the right handle corresponding to axes1)
image(bla bla bla)

if you feed the axes handle instead of the figure handle it gives the very frustrating unhelpfull message : Requested figure handle in use by another object.
what I found is that there is only one figure (handles.figure1) in the GUI but many axes zones.

instead of using this to get the parent figure handle :

figure(get(handles.axes1,'Parent'))
image(bla bla bla)

which always select the overall figure and not the wanted axes1, I use this:

subplot(handles.axes1)
image(bla bla bla)

which seems to select a unknown figure handle related for my axes1 area.
This time I can play with as many display. I do not use subplot to split the figure but it seems to find the right axes1 figure and it is valid syntax in the help.
it solved the problem for me.
