typedef struct NumericalEntry_struct NumericalEntry;
Short form for a NumericalEntry_struct structure.
struct NumericalEntry_struct;
Private structure to store informations of a NumericalEntry object.
GtkWidget* numericalEntry_new (double value);
A NumericalEntry widget is like a GtkEntry widget, but it only accepts double precision values (written in plain format, e.g. 1.23456, or scientific notation, e.g. 1.2345e6). The widget can(t be blank and there is always a value printed in it. If the user erase the current value or enter something that is not a recognised double precision value, the widget returns to its previous valid value.
