tmplPrintOperationPreviewT()

Functions

void endPreview()

Ends a preview.

This function must be called to finish a custom print preview.

bool isSelected(int pageNr)

Returns whether the given page is included in the set of pages that have been selected for printing.

Parameters

pageNr a page number

Returns

true if the page has been selected for printing

void renderPage(int pageNr)

Renders a page to the preview, using the print context that was passed to the #GtkPrintOperation::preview handler together with preview.

A custom iprint preview should use this function in its ::expose handler to render the currently selected page.

Note that this function requires a suitable cairo context to be associated with the print context.

Parameters

pageNr the page to render

gulong connectGotPageSize(T)(T callback, Flag!"After" after = No.After) if (isCallable!T && is(ReturnType!T == void) && (Parameters!T.length < 1 || (ParameterStorageClassTuple!T[0] == ParameterStorageClass.none && is(Parameters!T[0] : gtk.print_context.PrintContext))) && (Parameters!T.length < 2 || (ParameterStorageClassTuple!T[1] == ParameterStorageClass.none && is(Parameters!T[1] : gtk.page_setup.PageSetup))) && (Parameters!T.length < 3 || (ParameterStorageClassTuple!T[2] == ParameterStorageClass.none && is(Parameters!T[2] : gtk.print_operation_preview.PrintOperationPreview))) && Parameters!T.length < 4)

Connect to GotPageSize signal.

The ::got-page-size signal is 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 [gtk.print_context.PrintContext.setCairoContext].

Parameters

`callback`	signal callback delegate or function to connect `void callback(gtk.print_context.PrintContext context, gtk.page_setup.PageSetup pageSetup, gtk.print_operation_preview.PrintOperationPreview printOperationPreview)` `context` the current #GtkPrintContext (optional) `pageSetup` the #GtkPageSetup for the current page (optional) `printOperationPreview` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID

gulong connectReady(T)(T callback, Flag!"After" after = No.After) if (isCallable!T && is(ReturnType!T == void) && (Parameters!T.length < 1 || (ParameterStorageClassTuple!T[0] == ParameterStorageClass.none && is(Parameters!T[0] : gtk.print_context.PrintContext))) && (Parameters!T.length < 2 || (ParameterStorageClassTuple!T[1] == ParameterStorageClass.none && is(Parameters!T[1] : gtk.print_operation_preview.PrintOperationPreview))) && Parameters!T.length < 3)

Connect to Ready signal.

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.

Parameters

`callback`	signal callback delegate or function to connect `void callback(gtk.print_context.PrintContext context, gtk.print_operation_preview.PrintOperationPreview printOperationPreview)` `context` the current #GtkPrintContext (optional) `printOperationPreview` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
