I have already found that the string property does not update as you type in an edit box. Therefore, is there any way I can make string property update each I press a key?
GUI the time set function works

A beginner just learning matlab gui. I'd like to change the string of an edit box when an key pressed to make the input to be numeric. And when testing this, I found I had to press Enter to make this set function work. And after commenting the set function, other works as expected. This is the code below.
function edit1_KeyPressFcn(hObject, eventdata, handles)
if ~ismember(eventdata.Key,'1234567890.')
origin = get(handles.edit1, 'string');
disp('error')
set(handles.edit1, 'string', origin(1:end-1));
else
disp('normal')
end
Each time I entered a number, it can show 'normal' each time. But when entering not a number, it just showed 'error' without setting the string until I pressed an 'Enter' to make it work. I'd like to know the time set function works in this case
