struct Gtk::PrintOperation::CustomWidgetApplySignal

Overview

Emitted right before ::begin-print if you added a custom widget in the ::create-custom-widget handler.

When you get this signal you should read the information from the custom widgets, as the widgets are not guaranteed to be around at a later time.

Defined in:

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