| 38 | * @Title: CtkPrintOperation | |||
| 39 | * @Short_description: High-level Printing API | |||
| 40 | * @See_also: #CtkPrintContext, #CtkPrintUnixDialog | |||
| 41 | * | |||
| 42 | * CtkPrintOperation is the high-level, portable printing API. | |||
| 43 | * It looks a bit different than other CTK+ dialogs such as the | |||
| 44 | * #CtkFileChooser, since some platforms don’t expose enough | |||
| 45 | * infrastructure to implement a good print dialog. On such | |||
| 46 | * platforms, CtkPrintOperation uses the native print dialog. | |||
| 47 | * On platforms which do not provide a native print dialog, CTK+ | |||
| 48 | * uses its own, see #CtkPrintUnixDialog. | |||
| 49 | * | |||
| 50 | * The typical way to use the high-level printing API is to create | |||
| 51 | * a CtkPrintOperation object with ctk_print_operation_new() when | |||
| 52 | * the user selects to print. Then you set some properties on it, | |||
| 53 | * e.g. the page size, any #CtkPrintSettings from previous print | |||
| 54 | * operations, the number of pages, the current page, etc. | |||
| 55 | * | |||
| 56 | * Then you start the print operation by calling ctk_print_operation_run(). | |||
| 57 | * It will then show a dialog, let the user select a printer and | |||
| 58 | * options. When the user finished the dialog various signals will | |||
| 59 | * be emitted on the #CtkPrintOperation, the main one being | |||
| 60 | * #CtkPrintOperation::draw-page, which you are supposed to catch | |||
| 61 | * and render the page on the provided #CtkPrintContext using Cairo. | |||

| 95 | * | |||
| 96 | * By default CtkPrintOperation uses an external application to do | |||
| 97 | * print preview. To implement a custom print preview, an application | |||
| 98 | * must connect to the preview signal. The functions | |||
| 99 | * ctk_print_operation_preview_render_page(), | |||
| 100 | * ctk_print_operation_preview_end_preview() and | |||
| 101 | * ctk_print_operation_preview_is_selected() | |||
| 102 | * are useful when implementing a print preview. | |||
