void Gtk::Range::set_adjustment | ( | Gtk::Adjustment& | adjustment | ) |

Sets the adjustment to be used as the "model" object for this range widget.

The adjustment indicates the current range value, the minimum and maximum range values, the step/page increments used for keybindings and scrolling, and the page size. The page size is normally 0 for Gtk::Scale and nonzero for Gtk::Scrollbar, and indicates the size of the visible area of the widget being scrolled. The page size affects the size of the scrollbar slider.

Parameters

  adjustment | A Gtk::Adjustment.

void Gtk::Range::set_fill_level | ( | double | fill_level | ) |

Set the new position of the fill level indicator.

The "fill level" is probably best described by its most prominent use case, which is an indicator for the amount of pre-buffering in a streaming media player. In that use case, the value of the range would indicate the current play position, and the fill level would be the position up to which the file/stream has been downloaded.

This amount of prebuffering can be displayed on the range's trough and is themeable separately from the trough. To enable fill level display, use set_show_fill_level(). The range defaults to not showing the fill level.

Additionally, it's possible to restrict the range's slider position to values which are smaller than the fill level. This is controller by set_restrict_to_fill_level() and is by default enabled.

Since gtkmm 2.12:

Parameters

  fill_level | The new position of the fill level indicator.

void Gtk::Range::set_flippable | ( | bool | flippable = `true` | ) |

If a range is flippable, it will switch its direction if it is horizontal and its direction is Gtk::TEXT_DIR_RTL.

See Gtk::Widget::get_direction().

Since gtkmm 2.18:

Parameters

  flippable | `true` to make the range flippable.

void Gtk::Range::set_increments | ( | double | step,
|  | double | page
| ) |  |

Sets the step and page sizes for the range.

The step size is used when the user clicks the Gtk::Scrollbar arrows or moves Gtk::Scale via arrow keys. The page size is used for example when moving via Page Up or Page Down keys.

Parameters

  step | Step size.
  page | Page size.

void Gtk::Range::set_inverted | ( | bool | setting = `true` | ) |

Ranges normally move from lower to higher values as the slider moves from top to bottom or left to right.

Inverted ranges have higher values at the top or on the right rather than on the bottom or left.

Parameters

  setting | `true` to invert the range.

void Gtk::Range::set_lower_stepper_sensitivity | ( | SensitivityType | sensitivity | ) |

Sets the sensitivity policy for the stepper that points to the 'lower' end of the GtkRange's adjustment.

Since gtkmm 2.10:

Parameters

  sensitivity | The lower stepper's sensitivity policy.

void Gtk::Range::set_min_slider_size | ( | bool | min_size = `true` | ) |

Sets the minimum size of the range's slider.

This function is useful mainly for Gtk::Range subclasses.

Since gtkmm 2.20:

Parameters

  min_size | The slider's minimum size.

void Gtk::Range::set_range | ( | double | min,
|  | double | max
| ) |  |

Sets the allowable values in the Gtk::Range, and clamps the range value to be between min and max.

(If the range has a non-zero page size, it is clamped between min and max - page-size.)

Parameters

  min | Minimum range value.
  max | Maximum range value.

void Gtk::Range::set_restrict_to_fill_level | ( | bool | restrict_to_fill_level = `true` | ) |

Sets whether the slider is restricted to the fill level.

See set_fill_level() for a general description of the fill level concept.

Since gtkmm 2.12:

Parameters

  restrict_to_fill_level | Whether the fill level restricts slider movement.

void Gtk::Range::set_show_fill_level | ( | bool | show_fill_level = `true` | ) |

Sets whether a graphical fill level is show on the trough.

See set_fill_level() for a general description of the fill level concept.

Since gtkmm 2.12:

Parameters

  show_fill_level | Whether a fill level indicator graphics is shown.

void Gtk::Range::set_slider_size_fixed | ( | bool | size_fixed = `true` | ) |

Sets whether the range's slider has a fixed size, or a size that depends on it's adjustment's page size.

This function is useful mainly for Gtk::Range subclasses.

Since gtkmm 2.20:

Parameters

  size_fixed | `true` to make the slider size constant.

void Gtk::Range::set_update_policy | ( | UpdateType | policy | ) |

Sets the update policy for the range.

Gtk::UPDATE_CONTINUOUS means that anytime the range slider is moved, the range value will change and the value_changed signal will be emitted. Gtk::UPDATE_DELAYED means that the value will be updated after a brief timeout where no slider motion occurs, so updates are spaced by a short time rather than continuous. Gtk::UPDATE_DISCONTINUOUS means that the value will only be updated when the user releases the button and ends the slider drag operation.

Deprecated: 2.24: There is no replacement. If you require delayed updates, you need to code it yourself.

Parameters

  policy | Update policy.

void Gtk::Range::set_upper_stepper_sensitivity | ( | SensitivityType | sensitivity | ) |

Sets the sensitivity policy for the stepper that points to the 'upper' end of the GtkRange's adjustment.

Since gtkmm 2.10:

Parameters

  sensitivity | The upper stepper's sensitivity policy.

void Gtk::Range::set_value | ( | double | value | ) |

Sets the current value of the range; if the value is outside the minimum or maximum range values, it will be clamped to fit inside them.

The range emits the Gtk::Range::signal_value_changed() signal if the value changes.

Parameters

  value | New value of the range.

Glib::SignalProxy< void,double > Gtk::Range::signal_adjust_bounds | ( |  | ) |

Slot Prototype:
  `void on_my_adjust_bounds(double new_value)`

Glib::SignalProxy< bool,ScrollType,double > Gtk::Range::signal_change_value | ( |  | ) |

The change_value signal is emitted when a scroll action is performed on a range.

It allows an application to determine the type of scroll event that occurred and the resultant new value. The application can handle the event itself and return true to prevent further processing. Or, by returning false, it can pass the event to other handlers until the default GTK+ handler is reached.

The value parameter is unrounded. An application that overrides the change_value signal is responsible for clamping the value to the desired number of decimal digits; the default handler clamps the value based on range->round_digits.

It is not possible to use delayed update policies in an overridden change_value handler.

Parameters

  scroll | the type of scroll action that was performed.
  new_value | the new value resulting from the scroll action.

Returns
  true to prevent other handlers from being invoked for the signal, or false to propagate the signal further.

Slot Prototype:
  `bool on_my_change_value(ScrollType scroll, double new_value)`

Glib::SignalProxy< void,ScrollType > Gtk::Range::signal_move_slider | ( |  | ) |

Slot Prototype:
  `void on_my_move_slider(ScrollType scroll)`

Glib::SignalProxy< void > Gtk::Range::signal_value_changed | ( |  | ) |

Slot Prototype:
  `void on_my_value_changed()`

void Gtk::Range::unset_adjustment | ( |  | ) |
