PrintOperation.connectPaginate

gulong connectPaginate(T)(T callback,  Flag!"After" after =  No.After) if (isCallable!T
    &&  is(ReturnType!T ==  bool)
   && (Parameters!T.length <  1 || (ParameterStorageClassTuple!T[0]  ==  ParameterStorageClass.none &&  is(Parameters!T[0] :  gtk.print_context.PrintContext)))

Connect to Paginate signal.

Emitted after the ::begin-print signal, but before the actual rendering starts.

It keeps getting emitted until a connected signal handler returns true.

The ::paginate signal is intended to be used for paginating a document in small chunks, to avoid blocking the user interface for a long time. The signal handler should update the number of pages using [gtk.print_operation.PrintOperation.setNPages], and return true if the document has been completely paginated.

If you don't need to do pagination in chunks, you can simply do it all in the ::begin-print handler, and set the number of pages from there.

Parameters

`callback`	signal callback delegate or function to connect `bool callback(gtk.print_context.PrintContext context, gtk.print_operation.PrintOperation printOperation)` `context` the [gtk.print_context.PrintContext] for the current operation (optional) `printOperation` the instance the signal is connected to (optional) `Returns` true if pagination is complete
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
