I want to select a file using uigetfile and then display the name in a Edit Field (text) window, What is the best way to do this in Appdesigner?

I have done a similar function in an app that I had designed in Guide. There, I could call uigetfile as soon as I clicked in the Edit Field (text) window using the Callback function, in which I called the uigetfile function.

In appdesigner I see only ValueChanged and ValueChanging function for the Edit Field (text) Component, neither of which seems to tbe the right Callback to use.

Can you replace the edit field with a button? Then you can use a ButtonPusedCallback or whatever.

But you could do ValueChanged function, then put uigetfile in there, so when you edit (and i think you have to click away or press enter to satify conditions for ValueChanged) the text the same thing happens.
