## Functions

### 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.

#### Parameters

separators | The allowed separators. |
allow_simplification | Whether to do simplification on the entered term. |
min_valid_value | The minimum allowed result value. |
max_valid_value | The maximum allowed result value. |

#### Returns

The new GimpNumberPairEntry widget.

                                       GimpAspectType aspect);

Sets the aspect of the ratio by swapping the left_number and right_number if necessary (or setting them to 1.0 in case that `aspect` is `GIMP_ASPECT_SQUARE`).

#### Parameters

entry | A GimpNumberPairEntry widget. |
aspect | The new aspect. |

Since: 2.4

### gimp_number_pair_entry_get_ratio ()

                                      gdouble ratio);

Sets the numbers of the GimpNumberPairEntry to have the desired ratio. If the new ratio is different than the previous ratio, the "ratio-changed" signal is emitted.

An attempt is made to convert the decimal number into a fraction with left_number and right_number < 1000.

#### Parameters

entry | A GimpNumberPairEntry widget. |
ratio | Ratio to set in the widget. |

Since: 2.4

### gimp_number_pair_entry_get_user_override ()

    gboolean
    gimp_number_pair_entry_get_user_override
                                   (GimpNumberPairEntry *entry);

#### Parameters

#### Parameters

entry | A GimpNumberPairEntry widget. |
string | Default string. |

Since: 2.4
