Struct gtk4::ScaleButtonBuilder

pub struct ScaleButtonBuilder { /* fields omitted */ }

A builder-pattern type to construct ScaleButton objects.

Implementations

impl ScaleButtonBuilder

pub fn new() -> Self

Create a new ScaleButtonBuilder.

pub fn build(self) -> ScaleButton

Build the ScaleButton.

pub fn adjustment<P: IsA<Adjustment>>(self, adjustment: &P) -> Self

The Adjustment that is used as the model.

pub fn icons(self, icons: Vec<String>) -> Self

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.

pub fn value(self, value: f64) -> Self

The value of the scale.

pub fn can_focus(self, can_focus: bool) -> Self

Whether the widget or any of its descendents can accept the input focus.

This property is meant to be set by widget implementations, typically in their instance init function.

pub fn can_target(self, can_target: bool) -> Self

Whether the widget can receive pointer events.

pub fn css_classes(self, css_classes: Vec<String>) -> Self

A list of css classes applied to this widget.

pub fn css_name(self, css_name: &str) -> Self

pub fn cursor(self, cursor: &Cursor) -> Self

The cursor used by widget.

pub fn focus_on_click(self, focus_on_click: bool) -> Self

Whether the widget should grab focus when it is clicked with the mouse.

This property is only relevant for widgets that can take focus.

pub fn focusable(self, focusable: bool) -> Self

This property is meant to be set by widget implementations, typically in their instance init function.

pub fn margin_bottom(self, margin_bottom: i32) -> Self

Margin on bottom side of widget.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from WidgetExt::set_size_request() for example.

pub fn margin_end(self, margin_end: i32) -> Self

pub fn opacity(self, opacity: f64) -> Self

The requested opacity of the widget.

pub fn overflow(self, overflow: Overflow) -> Self

How content outside the widget’s content area is treated.
