Trait containing all ScaleButton methods.

Implementors

ScaleButton, VolumeButton

Required methods

fn get_adjustment(&self) -> Adjustment

Gets the Adjustment associated with the ScaleButton’s scale. See RangeExt::get_adjustment for details.

Returns

the adjustment associated with the scale

fn get_minus_button(&self) -> Option<Button>

Retrieves the minus button of the ScaleButton.

Returns

the minus button of the ScaleButton as a Button

fn get_plus_button(&self) -> Option<Button>

Retrieves the plus button of the ScaleButton.

Returns

the plus button of the ScaleButton as a Button

fn get_popup(&self) -> Option<Widget>

Retrieves the popup of the ScaleButton.

Returns

the popup of the ScaleButton

fn get_value(&self) -> f64

Gets the current value of the scale button.

Returns

current value of the scale button

fn set_adjustment<P: IsA<Adjustment>>(&self, adjustment: &P)

Sets the Adjustment to be used as a model for the ScaleButton’s scale. See RangeExt::set_adjustment for details.

adjustment

a Adjustment

fn set_icons(&self, icons: &[&str])

Sets the icons to be used by the scale button. For details, see the ScaleButton:icons property.

icons

a None-terminated array of icon names

fn set_value(&self, value: f64)

Sets the current value of the scale; if the value is outside the minimum or maximum range values, it will be clamped to fit inside them. The scale button emits the ScaleButton::value-changed signal if the value changes.

value

new value of the scale button

fn get_property_icons(&self) -> Vec<GString>

The names of the icons to be used by the scale button. The first item in the array will be used in the button when the current value is the lowest value, the second item for the highest value. All the subsequent icons will be used for all the other values, spread evenly over the range of values.

If there's only one icon name in the icons array, it will be used for all the values. If only two icon names are in the icons array, the first one will be used for the bottom 50% of the scale, and the second one for the top 50%.

It is recommended to use at least 3 icons so that the ScaleButton reflects the current value of the scale better for the users.

fn get_property_size(&self) -> IconSize

fn set_property_size(&self, size: IconSize)

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

The ::popdown signal is a [keybinding signal][BindingSignal] which gets emitted to popdown the scale widget.

The default binding for this signal is Escape.

fn emit_popdown(&self)

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

The ::popup signal is a [keybinding signal][BindingSignal] which gets emitted to popup the scale widget.

The default bindings for this signal are Space, Enter and Return.

fn emit_popup(&self)

fn connect_value_changed<F: Fn(&Self, f64) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

The ::value-changed signal is emitted when the value field has changed.

value

the new value

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

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

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

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