LevelBar

Required methods

fn add_offset_value(&self, name: &str, value: f64)

Adds a new offset marker on self at the position specified by value. When the bar value is in the interval topped by value (or between value and LevelBar:max-value in case the offset is the last one on the bar) a style class named level-``name will be applied when rendering the level bar fill. If another offset marker named name exists, its value will be replaced by value.

name

the name of the new offset

value

the value for the new offset

fn get_inverted(&self) -> bool

Return the value of the LevelBar:inverted property.

Returns

true if the level bar is inverted

fn get_max_value(&self) -> f64

Returns the value of the LevelBar:max-value property.

Returns

a positive value

fn get_min_value(&self) -> f64

Returns the value of the LevelBar:min-value property.

Returns

a positive value

fn get_mode(&self) -> LevelBarMode

Returns the value of the LevelBar:mode property.

Returns

a LevelBarMode

fn get_offset_value(&self, name: Option<&str>) -> Option<f64>

Fetches the value specified for the offset marker name in self, returning true in case an offset named name was found.

name

the name of an offset in the bar

value

location where to store the value

Returns

true if the specified offset is found

fn get_value(&self) -> f64

Returns the value of the LevelBar:value property.

Returns

a value in the interval between LevelBar:min-value and LevelBar:max-value

fn remove_offset_value(&self, name: Option<&str>)

Removes an offset marker previously added with LevelBarExt::add_offset_value.

name

the name of an offset in the bar

fn set_inverted(&self, inverted: bool)

Sets the value of the LevelBar:inverted property.

inverted

true to invert the level bar

fn set_max_value(&self, value: f64)

Sets the value of the LevelBar:max-value property.

You probably want to update preexisting level offsets after calling this function.

value

a positive value

fn set_min_value(&self, value: f64)

Sets the value of the LevelBar:min-value property.

You probably want to update preexisting level offsets after calling this function.

value

a positive value

fn set_mode(&self, mode: LevelBarMode)

Sets the value of the LevelBar:mode property.

mode

a LevelBarMode

fn set_value(&self, value: f64)

Sets the value of the LevelBar:value property.

value

a value in the interval between LevelBar:min-value and LevelBar:max-value

fn connect_offset_changed<F: Fn(&Self, &str) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

Emitted when an offset specified on the bar changes value as an effect to LevelBarExt::add_offset_value being called.

The signal supports detailed connections; you can connect to the detailed signal "changed::x" in order to only receive callbacks when the value of offset "x" changes.

name

the name of the offset that changed value

fn connect_property_inverted_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_max_value_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_min_value_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_mode_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_value_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId
