Constructor Details

PrintOperationPreview

public PrintOperationPreview(PointerContainer pointer)

Method Details

getClassHandler

public static ClassHandler getClassHandler()

endPreview

public void endPreview()

Ends a preview.

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

isSelected

public boolean isSelected(int page_nr)

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

Parameters:

page_nr - a page number

Returns:

%TRUE if the page has been selected for printing

renderPage

public void renderPage(int page_nr)

Renders a page to the preview.

This is using the print context that was passed to the
[signal@Gtk.PrintOperation::preview] handler together
with @preview.

A custom print preview should use this function to render
the currently selected page.

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

Parameters:

page_nr - the page to render

onGotPageSize

public SignalHandler onGotPageSize(PrintOperationPreview.OnGotPageSize signal)

Connect to signal "got-page-size".
See PrintOperationPreview.OnGotPageSize.onGotPageSize(ch.bailu.gtk.gtk.PrintContext, ch.bailu.gtk.gtk.PageSetup) for signal description.
Field SIGNAL_ON_GOT_PAGE_SIZE contains original signal name and can be used as resource reference.

Parameters:

signal - callback function (lambda).

Returns:

SignalHandler. Can be used to disconnect signal and to release callback function.

onReady

public SignalHandler onReady(PrintOperationPreview.OnReady signal)

Connect to signal "ready".
See PrintOperationPreview.OnReady.onReady(ch.bailu.gtk.gtk.PrintContext) for signal description.
Field SIGNAL_ON_READY contains original signal name and can be used as resource reference.

Parameters:

signal - callback function (lambda).

Returns:

SignalHandler. Can be used to disconnect signal and to release callback function.

getTypeID

public static long getTypeID()

getParentTypeID

public static long getParentTypeID()

getTypeSize

public static TypeSystem.TypeSize getTypeSize()

getParentTypeSize

public static TypeSystem.TypeSize getParentTypeSize()

getInstanceSize

public static int getInstanceSize()
