[Qt-interest] Initial text selection in dialogs

[Kyle Alons]

On Windows, when a dialog is displayed and an edit or editable combo control 
is the first focused field, that field's text is selected.  With a Qt 
application (using 4.5.1), it isn't selected (although it is when tabbing 
away and back to that field).  For instance, see the findfiles example.  How 
to get the proper initial selection behavior on Windows?  Or how to manually 
select the text of an editable QComboBox?  Thanks.
