How can I avoid displaying "0" in my text box when cancel is pressed using UIGETDIR

2 views (last 30 days)
Hi,
The dialog box UIGETDIR returns either the selected folder name as a string if OK is pressed or the number 0 if Cancel is pressed. In my application I have an edit box with a callback function that calls UIGETDIR and then displays the selected folder string, something like this:
editboxhandle.callbackfcn = @set(editboxhandle,'String',uigetdir);
However, when Cancel is pressed, "0" is displayed in my edit box but while I would like the string to be empty in such case. I'm am restricted to a singel expression callback like the one above. How can I solve this?

k=uigetdir;
if k==0;
k=[];
end

Why do you need to do it in a single line?
k=uigetdir;
if k==0;
k=[];
end
editboxhandle.callbackfcn = @char(set(editboxhandle,'String',k))
