## Description

## Details

### GimpNumberPairEntry

    typedef struct _GimpNumberPairEntry GimpNumberPairEntry;

### enum GimpAspectType

    typedef enum
    {
      GIMP_ASPECT_SQUARE,    /*< desc="Square"    >*/
      GIMP_ASPECT_PORTRAIT,  /*< desc="Portrait"  >*/
      GIMP_ASPECT_LANDSCAPE  /*< desc="Landscape" >*/
    } GimpAspectType;

### gimp_number_pair_entry_new ()

    GtkWidget*          gimp_number_pair_entry_new          (const gchar *separators,
                                                             gboolean allow_simplification,
                                                             gdouble min_valid_value,
                                                             gdouble max_valid_value);

Creates a new GimpNumberPairEntry widget, which is a GtkEntry that accepts two numbers separated by a separator. Typical input example with a 'x' separator: "377x233".

The widget supports simplification of the entered ratio when the input ends in '=', if "allow-simplification" is TRUE.

The "separators" property contains a string of characters valid as separators when parsing input. The first separator is used when displaying the current values.

It is possible to specify what range of values that shall be considered as valid when parsing user input, by changing "min-valid-value" and "max-valid-value".

The first separator of `separators` is used to display the current value.

`separators` : |
`allow_simplification` : |
`min_valid_value` : |
`max_valid_value` : |
Returns : | The new GimpNumberPairEntry widget.
