/**
|
|
\class Fl_File_Input
|
|
\brief This widget displays a pathname in a text input field.
|
|
|
|
A navigation bar located above the input field allows the user to
|
|
navigate upward in the directory tree.
|
|
You may want to handle FL_WHEN_CHANGED events for tracking text changes
|
|
and also FL_WHEN_RELEASE for button release when changing to parent dir.
|
|
FL_WHEN_RELEASE callback won't be called if the directory clicked
|
|
is the same that the current one.
|
|

|
\image latex Fl_File_Input.eps "Fl_File_Input" width=6cm
|
|
\note As all Fl_Input derived objects, Fl_File_Input may call its callback
|
|
when loosing focus (see FL_UNFOCUS) to update its state like its cursor shape.
|
|
One resulting side effect is that you should call clear_changed() early in your callback
|
|
to avoid reentrant calls if you plan to show another window or dialog box in the callback.
