File/directory picker controls with wxFLP_FILE_MUST_EXIST/wxDIRP_DIR_MUST_EXIST style simply ignored any value entered by user if it didn't correspond to an existing file/directory. This meant that the program didn't use the value that was shown on the screen resulting in very confusing UI -- e.g. a program could complain that no value was entered when actually it was and just corresponded to a non-existing file. As we can't prevent the entry of arbitrary strings in the text field of the file picker control, stop pretending that we can validate it and just update the control value, and send the corresponding event, whenever the text control value changes. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@72475 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
