Programatically getting contents from an edit box.

sorry to raise another thread, I had previously closed with an accepted answer, but this was by mistake. I have tried all suggestions but not getting this to work, even with the handles.figure1 suggestion. To simplify, I programmatically create a checkbox and edit box via:

checkboxCumsum= uicontrol('Style', 'checkbox',...
           'String', {'Cum Sum'},...
           'Position', [620 0 80 30],...
           'Callback',  @(src,evt) CumSum( src, evt, ax1,handles.figure1 ));        

edx = uicontrol('Style', 'edit',...
           'String', {'95'},...
           'Position', [700 5 40 20]);

I then create a function Cumsum as:

function CumSum(source,event,ax,handles)
         val = source.Value
         h=getappdata(0,'histog')  %previously drawn histogram
         if val==1
              hline = findall(gca, 'type', 'line');
              delete(hline);
              counts=h.Values;
              edges=h.BinEdges;
              width=h.BinWidth;
              ctrs=edges(1:end-1)+width/2;    
              %integrate histogram using cumsum
              cs=cumsum(counts)
              l=cs(end)
              l1=0.95*l
              [ii]=find(cs>l1)
              ct=ctrs(ii(1))
              hold on
              lineH1=plot([ct ct],ylim,'b--','LineWidth',0.7);
              text(ct+5,0.90*max(ylim),  ['CumSum95=',num2str(ct,'%.0f')],'Fontsize',8,'Color','k','FontWeight','normal')
             hold off
             x=str2num(get(handles.edx,'String'))
         end

I still get the error

No appropriate method, property, or field 'edx' for class 'matlab.ui.Figure'.

How are you passing edx to the function CumSum ?

I thought through passing the handles structure?

[Jason]

yes...done it, I have used the Tag property. So in the edit box creation:

edx = uicontrol('Style', 'edit',...
           'String', {'95'},...
           'Tag','editCumSum',...
           'Position', [700 5 40 20]);

And then in the function

               hedit = findobj('Tag','editCumSum')
               I=cell2mat(hedit.String)
