VisuUiNumericalEntry implements AtkImplementorIface, GtkBuildable, GtkEditable and GtkCellEditable.
This widget is based on the GtkEntry widget but behaves more like a GtkSpinButton is fact. It is designed to enter numerical values, but without any boundary or precision constrains. One can use either plain or scientific notations.
typedef struct _VisuUiNumericalEntry VisuUiNumericalEntry;
Short form for a VisuUiNumericalEntry_struct structure.
typedef struct _VisuUiNumericalEntryClass VisuUiNumericalEntryClass;
Opaque structure.
double visu_ui_numerical_entry_getValue (VisuUiNumericalEntry *numericalEntry
);
You can get the value contained in the given numericalEntry
using this method.

a VisuUiNumericalEntry widget. |
Returns : |
the double precision value printed in the VisuUiNumericalEntry. |
GtkWidget * visu_ui_numerical_entry_new (double value
);
A VisuUiNumericalEntry 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.
|
the initial value. |
Returns : |
a newly created VisuUiNumericalEntry widget. |
void visu_ui_numerical_entry_setValue (VisuUiNumericalEntry *numericalEntry
,double value
);
Use this method to set the value for the given numericalEntry widget.
|
a VisuUiNumericalEntry widget ; |
|
a double precision value. |
