class Gtk::CustomLayout

Overview

Gtk::CustomLayout uses closures for size negotiation.

A Gtk::CustomLayout uses closures matching to the old Gtk::Widget virtual functions for size negotiation, as a convenience API to ease the porting towards the corresponding `Gtk::LayoutManager virtual functions.

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/custom_layout.cr

Constructor Detail

def self.new(request_mode : Gtk::CustomRequestModeFunc | Nil, measure : Gtk::CustomMeasureFunc, allocate : Gtk::CustomAllocateFunc) : self #

Creates a new legacy layout manager.

Legacy layout managers map to the old Gtk::Widget size negotiation virtual functions, and are meant to be used during the transition from layout containers to layout manager delegates.
