Thread Subject: uigetdir in a gui

I'm having a little trouble implementing a "browse button" in my gui. The button
should allow the user to select a directory and, after this is done, to return the
directory to an "edit text" box also in the gui, which in turn, returns the entire
string to my image analysis function.

Another "browse button" should perform the same function, only for an output
"edit text" box, so the user can select which directory to ouput the analysis file
into.

However, whenever I click on the browse buttons, nothing happens. No error
message or anything. Here is the code for the input browse button:

function input_browse_Callback(hInbrowse,eventdata,handles)
indir=uigetdir;
handles.input=char(indir)
function input_browse_CreateFcn(hInbrowse,eventdata,handles)

If the edit box you want to place the directory text into
has the tag edit1 for example then replace the statement:

handles.input=char(indir);

with:

set(handles.edit1, 'String', indir);

to see your selected directory show up in the edit box.

Thanks Donn, but I also have the problem that when I click on the browse
button, the uigetdir box doesn't even appear. Nothing happens (I've checked
the tag links, too, and they match up).

This example gui does some of what you want. I think you'll
get the idea.



function [] = mygui_s()
% The basic layout of this GUI was made with the help of
% guidegetter, available on the File Exchange at
% Mathworks.com

hf = figure('units','normalized','position',...
[0.3 0.5 0.3 0.1],...
'menubar','none','name',...
'mygui_s','numbertitle','off','color',...
    [0.831 0.816 0.784]);
edit1=uicontrol(hf,'style','edit','units','normalized',...
    'position',[0.1 0.5 0.8 0.4],'string','edit1',...
'backgroundcolor',...
    [1 1 1]);
pushbutton1 =
uicontrol(hf,'style','pushbutton','units','normalized',...
    'position',[0.1 0.1 0.8 0.2],'string','pushbutton1',...
    'backgroundcolor',[0.831 0.816 0.784],'callback',...
    {@input_browse_Callback,edit1});


function input_browse_Callback(hand,eventdata,edit1)
indir=uigetdir;
set(edit1,'string',indir)
set(hand,'userdata',indir)

Thanks for all your help, but for some reason, my pushbuttons are still
unresponsive. The problem isn't so much that they're calling an erroneous
function, but that they aren't calling a function at all.

I'm an idiot. I got it fixed.

Turns out I had set the tag for each browse button, but I hadn't typed anything
in the "callback" or "createfcn" zones.

Thanks for your help.

Post your code nd I will have a look.

Sounds like you were using GUIDE or some other GUI constructor.
That would have been a useful fact for the problem-solvers to know.

I am having a similar problem (using GUIDE by the way). I have a "browse" button...

% --- Executes on button press in ExBrowse.
function ExBrowse_Callback(hObject, eventdata, handles)
% hObject handle to ExBrowse (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
[FileEx,PathEx] = uigetfile('*.xls','Select the Excitation Correction File');
ExPath = [PathEx FileEx];

handles.ExPath = ExPath;
guidata(hObject,handles);
set(handles.ExLoc,'String',ExPath);

and would like the path to be displayed in a text field that has its tag as ExLoc, but nothing appears in the field.
