Struct gtk4::CellRendererSpin

#[repr(transparent)]
pub struct CellRendererSpin { /* private fields */ }

Renders a spin button in a cell

CellRendererSpin renders text in a cell like CellRendererText from which it is derived. But while CellRendererText offers a simple entry to edit the text, CellRendererSpin offers a SpinButton widget. Of course, that means that the text has to be parseable as a floating point number.

The range of the spinbutton is taken from the adjustment property of the cell renderer, which can be set explicitly or mapped to a column in the tree model, like all properties of cell renders. CellRendererSpin also has properties for the GtkCellRendererSpin:climb-rate and the number of GtkCellRendererSpin:digits to display. Other SpinButton properties can be set in a handler for the GtkCellRenderer::editing-started signal.

The CellRendererSpin cell renderer was added in GTK 2.10.

Implementations

impl CellRendererSpin

pub fn new() -> CellRendererSpin

Creates a new CellRendererSpin.

Returns

a new CellRendererSpin

pub fn builder() -> CellRendererSpinBuilder

Creates a new builder-pattern struct instance to construct CellRendererSpin objects.

This method returns an instance of CellRendererSpinBuilder which can be used to create CellRendererSpin objects.

pub fn adjustment(&self) -> Option<Adjustment>

The adjustment that holds the value of the spinbutton. This must be non-None for the cell renderer to be editable.

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

The adjustment that holds the value of the spinbutton. This must be non-None for the cell renderer to be editable.

pub fn climb_rate(&self) -> f64

The acceleration rate when you hold down a button.

pub fn set_climb_rate(&self, climb_rate: f64)

The acceleration rate when you hold down a button.

pub fn digits(&self) -> u32

The number of decimal places to display.

pub fn set_digits(&self, digits: u32)

The number of decimal places to display.

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

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