Update slider value after enter a value in editbox.

I have a slider that I can use to increment an editbox. However I also need to be able to enter a value in the editbox. If I enter a value in editbox and them I cick on the slider it not work properly (if before I don’t press enter). I try to update the value of the slider on the editbox callback by doing something like:

set(hslider, 'value', val);

But this don’t work properly which I believe is related with the need to add an enter after add the value to a editbox.

Why you don't want to use enter button?

Correct. The Callback of the Edit box is not invoked until an enter is received.

But there is now way to update the slider? Or programmatically add an enter?

How would you know that it was needed?

Take a look at my FEX submission "Regular Expression Helper", it uses the key-press function to update strings used in regexp (and displays the output). This would be easy to adapt to update a slider value.

Thank you Walter and Stephen. In fact I have been looking to the example of Matt Fig (using keypress) reported here: http://www.mathworks.com/matlabcentral/answers/8921-pull-string-out-of-edit-text-without-user-hitting-enter

Which is similar to what Stephen was suggesting. However until now I was unable to update the slider properlly.

The is any chance that you can show me and example about how to perform this?

Thank you for the help .

The problem with using the KeyPressFcn is that you do not know whether the user is finished typing unless you see the user type a particular character such as return.

Yes indeed. That is a big issue. Thank you for all the help.
