Description

Details

NumericalEntry

typedef struct NumericalEntry_struct        NumericalEntry;

Short form for a NumericalEntry_struct structure.


struct NumericalEntry_struct

struct NumericalEntry_struct;

Private structure to store informations of a NumericalEntry object.


numericalEntry_new ()

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.

value : the initial value.
Returns : a newly created NumericalEntry widget.

numericalEntryGet_value ()

double      numericalEntryGet_value         (NumericalEntry *numericalEntry);

You can get the value contained in the given numericalEntry using this method.

numericalEntry : a NumericalEntry widget.
Returns : the double precision value printed in the NumericalEntry.

numericalEntrySet_value ()

void        numericalEntrySet_value         (NumericalEntry *numericalEntry,
                                             double value);

Use this method to set the value for the given numericalEntry widget.

numericalEntry : a NumericalEntry widget ;
value : a double precision value.
