CellRendererSpinnerProtocol

public protocol CellRendererSpinnerProtocol : CellRendererProtocol

Renders a spinning animation in a cell

GtkCellRendererSpinner renders a spinning animation in a cell, very similar to GtkSpinner. It can often be used as an alternative to a GtkCellRendererProgress for displaying indefinite activity, instead of actual progress.

To start the animation in a cell, set the GtkCellRendererSpinner:active property to true and increment the GtkCellRendererSpinner:pulse property at regular intervals. The usual way to set the cell renderer properties for each cell is to bind them to columns in your tree model using e.g. gtk_tree_view_column_add_attribute().

The CellRendererSpinnerProtocol protocol exposes the methods and properties of an underlying GtkCellRendererSpinner instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see CellRendererSpinner. Alternatively, use CellRendererSpinnerRef as a lighweight, unowned reference if you already have an instance you just want to use.

    target

    the target object to bind to
    target_property

    the target property to bind to
    flags

    the flags to pass to the Binding

  • get(property:) Extension method

    Get the value of a CellRendererSpinner property

    Declaration

    Swift

    @inlinable
func get(property: CellRendererSpinnerPropertyName) -> GLibObject.Value

    Parameters

    property

    the property to get the value for

    Return Value

func set(property: CellRendererSpinnerPropertyName, value v: GLibObject.Value)

    Parameters

    property

    the property to get the value for

    Return Value
