class (GObject o, IsDescendantOf PrintOperationPreview o) => IsPrintOperationPreview o

Type class for types which can be safely cast to PrintOperationPreview, for instance with toPrintOperationPreview.

endPreview

printOperationPreviewEndPreview

Arguments

:: (HasCallStack, MonadIO m, IsPrintOperationPreview a)

=> a

preview: a PrintOperationPreview

-> m ()

Ends a preview.

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

Since: 2.10

isSelected

printOperationPreviewIsSelected

Arguments

:: (HasCallStack, MonadIO m, IsPrintOperationPreview a)

=> a

preview: a PrintOperationPreview

-> Int32

pageNr: a page number

-> m Bool

Returns: True if the page has been selected for printing

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

Since: 2.10

renderPage

printOperationPreviewRenderPage

Arguments

:: (HasCallStack, MonadIO m, IsPrintOperationPreview a)

=> a

preview: a PrintOperationPreview

-> Int32

pageNr: the page to render

-> m ()

Renders a page to the preview, using the print context that was passed to the 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.

Since: 2.10

Signals

gotPageSize

type C_PrintOperationPreviewGotPageSizeCallback = Ptr () -> Ptr PrintContext -> Ptr PageSetup -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type PrintOperationPreviewGotPageSizeCallback

Arguments

 = PrintContext

context: the current PrintContext

-> PageSetup

pageSetup: the PageSetup for the current page

-> IO ()

The gotPageSize signal is emitted once for each page that gets rendered to the preview.

A handler for this signal should update the context according to pageSetup and set up a suitable cairo context, using printContextSetCairoContext.

afterPrintOperationPreviewGotPageSize :: (IsPrintOperationPreview a, MonadIO m) => a -> PrintOperationPreviewGotPageSizeCallback -> m SignalHandlerId

Connect a signal handler for the gotPageSize signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after printOperationPreview #gotPageSize callback

genClosure_PrintOperationPreviewGotPageSize :: MonadIO m => PrintOperationPreviewGotPageSizeCallback -> m (GClosure C_PrintOperationPreviewGotPageSizeCallback)

Wrap the callback into a GClosure.

mk_PrintOperationPreviewGotPageSizeCallback :: C_PrintOperationPreviewGotPageSizeCallback -> IO (FunPtr C_PrintOperationPreviewGotPageSizeCallback)

Generate a function pointer callable from C code, from a C_PrintOperationPreviewGotPageSizeCallback.

noPrintOperationPreviewGotPageSizeCallback :: Maybe PrintOperationPreviewGotPageSizeCallback

A convenience synonym for Nothing :: Maybe PrintOperationPreviewGotPageSizeCallback.

onPrintOperationPreviewGotPageSize :: (IsPrintOperationPreview a, MonadIO m) => a -> PrintOperationPreviewGotPageSizeCallback -> m SignalHandlerId

Connect a signal handler for the gotPageSize signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on printOperationPreview #gotPageSize callback

wrap_PrintOperationPreviewGotPageSizeCallback :: PrintOperationPreviewGotPageSizeCallback -> C_PrintOperationPreviewGotPageSizeCallback

Wrap a PrintOperationPreviewGotPageSizeCallback into a C_PrintOperationPreviewGotPageSizeCallback.

ready

type C_PrintOperationPreviewReadyCallback = Ptr () -> Ptr PrintContext -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type PrintOperationPreviewReadyCallback

Arguments

 = PrintContext

context: the current PrintContext

-> IO ()

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.

afterPrintOperationPreviewReady :: (IsPrintOperationPreview a, MonadIO m) => a -> PrintOperationPreviewReadyCallback -> m SignalHandlerId

Connect a signal handler for the ready signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after printOperationPreview #ready callback

genClosure_PrintOperationPreviewReady :: MonadIO m => PrintOperationPreviewReadyCallback -> m (GClosure C_PrintOperationPreviewReadyCallback)

Wrap the callback into a GClosure.

mk_PrintOperationPreviewReadyCallback :: C_PrintOperationPreviewReadyCallback -> IO (FunPtr C_PrintOperationPreviewReadyCallback)

Generate a function pointer callable from C code, from a C_PrintOperationPreviewReadyCallback.

noPrintOperationPreviewReadyCallback :: Maybe PrintOperationPreviewReadyCallback

A convenience synonym for Nothing :: Maybe PrintOperationPreviewReadyCallback.

onPrintOperationPreviewReady :: (IsPrintOperationPreview a, MonadIO m) => a -> PrintOperationPreviewReadyCallback -> m SignalHandlerId

Connect a signal handler for the ready signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on printOperationPreview #ready callback

wrap_PrintOperationPreviewReadyCallback :: PrintOperationPreviewReadyCallback -> C_PrintOperationPreviewReadyCallback

Wrap a PrintOperationPreviewReadyCallback into a C_PrintOperationPreviewReadyCallback.
