Hi, I have more questions? When you load paintings (DICOM) in the list box will display the first list, but when I select another from the listbox does not appear. Thanks a lot in advance.
h1=figure;
handles.ListBox=uicontrol('Units','Normalized','Position',[0.01 0.1 0.1 0.15],...
'Style','List');
P=fileparts(mfilename('fullpath'));
nfolder=uigetdir(P,'cokoliv');
handles.dfolder=nfolder;
dfiles=dir(handles.dfolder);
dfiles=dfiles(3:end);
nfiles=length(dfiles);
if nfiles<1
disp('no files availabel.')
return;
end
set(handles.ListBox,'String',char(dfiles.name),'value',1);
s = [num2str(nfiles) ' files in: ' handles.dfolder];
fname=get(handles.ListBox,'String');
fname=fname(get(handles.ListBox,'value'),:);
info=dicominfo([handles.dfolder '\' fname]);
Y1=dicomread(info);
imshow(Y1)
clims = [10 1800];

Your part from 'fname=' onward should be in a separate routine that you have set as being the Callback for the uicontrol. This will probably require that you wrap your original code inside a function
function dilist
h1 = figure;
handles.ListBox=uicontrol('Units','Normalized','Position',[0.01 0.1 0.1 0.15],...
'Style','List', 'Callback', @dilist_callback);
P=<etc>
[...]
s = [num2str(nfiles) ' files in: ' handles.dfolder];
end
function dilist_callback(src, evt)
fname=get(handles.ListBox,'String');
fname=fname(get(handles.ListBox,'value'),:);
info=dicominfo([handles.dfolder '\' fname]);
Y1=dicomread(info);
imshow(Y1)
clims = [10 1800];
end
