CellRendererSpinRef Structure Reference
CellRendererSpinRef
public struct CellRendererSpinRef : CellRendererSpinProtocol, GWeakCapturingRenders a spin button in a cell
GtkCellRendererSpin renders text in a cell like GtkCellRendererText from
which it is derived. But while GtkCellRendererText offers a simple entry to
edit the text, GtkCellRendererSpin offers a GtkSpinButton 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. GtkCellRendererSpin
also has properties for the GtkCellRendererSpin:climb-rate and the number
of GtkCellRendererSpin:digits to display. Other GtkSpinButton properties
can be set in a handler for the GtkCellRendererediting-started`` signal.
The GtkCellRendererSpin cell renderer was added in GTK 2.10.
The CellRendererSpinRef type acts as a lightweight Swift reference to an underlying GtkCellRendererSpin instance.
It exposes methods that can operate on this data type through CellRendererSpinProtocol conformance.
Use CellRendererSpinRef only as an unowned reference to an existing GtkCellRendererSpin instance.
