Exported types
newtype PrintOperationPreview Source #
Memory-managed wrapper type.
Constructors
| PrintOperationPreview (ManagedPtr PrintOperationPreview) |
Instances
noPrintOperationPreview :: Maybe PrintOperationPreview Source #
A convenience alias for Nothing :: Maybe PrintOperationPreview.
class GObject o => IsPrintOperationPreview o Source #
Type class for types which can be safely cast to PrintOperationPreview, for instance with toPrintOperationPreview.
Instances
toPrintOperationPreview :: (MonadIO m, IsPrintOperationPreview o) => o -> m PrintOperationPreview Source #
Cast to PrintOperationPreview, for types for which this is known to be safe. For general casts, use castTo.
Methods
endPreview
printOperationPreviewEndPreview Source #
Arguments
| :: (HasCallStack, MonadIO m, IsPrintOperationPreview a) | |
| => a |
|
| -> m () |
Ends a preview.
This function must be called to finish a custom print preview.
Since: 2.10
isSelected
printOperationPreviewIsSelected Source #
Arguments
| :: (HasCallStack, MonadIO m, IsPrintOperationPreview a) | |
| => a |
|
| -> Int32 |
|
| -> m Bool | Returns: |
Returns whether the given page is included in the set of pages that have been selected for printing.
Since: 2.10
renderPage
printOperationPreviewRenderPage Source #
Arguments
| :: (HasCallStack, MonadIO m, IsPrintOperationPreview a) | |
| => a |
|
| -> Int32 |
|
| -> m () |
Renders a page to the preview, using the print context that
was passed to the PrintOperation::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 () Source #
Type for the callback on the (unwrapped) C side.
type PrintOperationPreviewGotPageSizeCallback Source #
Arguments
| = PrintContext |
|
| -> PageSetup |
|
| -> IO () |
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 pageSetup and set up a suitable cairo
context, using printContextSetCairoContext.
afterPrintOperationPreviewGotPageSize :: (IsPrintOperationPreview a, MonadIO m) => a -> PrintOperationPreviewGotPageSizeCallback -> m SignalHandlerId Source #
Connect a signal handler for the “got-page-size” signal, to be run after the default handler.
When overloading is enabled, this is equivalent to
after printOperationPreview #gotPageSize callback
genClosure_PrintOperationPreviewGotPageSize :: PrintOperationPreviewGotPageSizeCallback -> IO Closure Source #
Wrap the callback into a Closure.
mk_PrintOperationPreviewGotPageSizeCallback :: C_PrintOperationPreviewGotPageSizeCallback -> IO (FunPtr C_PrintOperationPreviewGotPageSizeCallback) Source #
Generate a function pointer callable from C code, from a C_PrintOperationPreviewGotPageSizeCallback.
noPrintOperationPreviewGotPageSizeCallback :: Maybe PrintOperationPreviewGotPageSizeCallback Source #
A convenience synonym for Nothing :: Maybe PrintOperationPreviewGotPageSizeCallback
onPrintOperationPreviewGotPageSize :: (IsPrintOperationPreview a, MonadIO m) => a -> PrintOperationPreviewGotPageSizeCallback -> m SignalHandlerId Source #
Connect a signal handler for the “got-page-size” 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 Source #
ready
type C_PrintOperationPreviewReadyCallback = Ptr () -> Ptr PrintContext -> Ptr () -> IO () Source #
Type for the callback on the (unwrapped) C side.
type PrintOperationPreviewReadyCallback Source #
Arguments
| = 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 Source #
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 :: PrintOperationPreviewReadyCallback -> IO Closure Source #
Wrap the callback into a Closure.
mk_PrintOperationPreviewReadyCallback :: C_PrintOperationPreviewReadyCallback -> IO (FunPtr C_PrintOperationPreviewReadyCallback) Source #
Generate a function pointer callable from C code, from a C_PrintOperationPreviewReadyCallback.
noPrintOperationPreviewReadyCallback :: Maybe PrintOperationPreviewReadyCallback Source #
A convenience synonym for Nothing :: Maybe PrintOperationPreviewReadyCallback
onPrintOperationPreviewReady :: (IsPrintOperationPreview a, MonadIO m) => a -> PrintOperationPreviewReadyCallback -> m SignalHandlerId Source #
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
