pub struct PrintOperationPreview { /* private fields */ }
Expand description
PrintOperationPreview
is the interface that is used to
implement print preview.
A PrintOperationPreview
object is passed to the
preview
signal by
PrintOperation
.
§Signals
§got-page-size
Emitted once for each page that gets rendered to the preview.
A handler for this signal should update the @context
according to @page_setup and set up a suitable cairo
context, using PrintContext::set_cairo_context()
.
§ready
The ::ready signal gets emitted once per preview operation, before the first page is rendered.
A handler for this signal can be used for setup tasks.
§Implements
GLib type: GObject with reference counted clone semantics.
