Subject Re: TextInput can't be made programmatically editable while it already has focus
Date Thu, 19 Sep 2013 16:40:36 GMT
Thank you Alex, but unfortunately the text input has to be focusable
because it is part of a complex search component: it accept a query text
and, on return, display a popup list of results, once selected the text
input become not editable and display the selected item. In other words,
the user move focus to the non editable text field, hit DELETE button to
clear the current value, and starts typing to search for another value.

In a previous approach I was using different skin parts for the display of
the selected value and for entering the query text, but this was leading to
other focus problem when the skinState of the component was switching
between the two (needed to "refocus" with mouse after clear/selection via
keyboard shortcuts).

With the current approach the component works perfectly, except when it is
initially loaded with a value already set... I was hoping to find a way to
trick it into initializing as an editable field in advance, to gain full
keyboard operativity.
