Those property features don't seem to be in use anywhere. They are redundant since the docs cover the same information and more. They also created unnecessary translation work. Closes #4904

/**
|
||
* GtkPrintOperation:
|
||
*
|
||
* `GtkPrintOperation` is the high-level, portable printing API.
|
||
*
|
||
* It looks a bit different than other GTK dialogs such as the
|
||
* `GtkFileChooser`, since some platforms don’t expose enough
|
||
* infrastructure to implement a good print dialog. On such
|
||
* platforms, `GtkPrintOperation` uses the native print dialog.
|
||
* On platforms which do not provide a native print dialog, GTK
|
||
* uses its own, see [class@Gtk.PrintUnixDialog].
|
||
*
|
||
* The typical way to use the high-level printing API is to create
|
||
* a `GtkPrintOperation` object with [ctor@Gtk.PrintOperation.new]
|
||
* when the user selects to print. Then you set some properties on it,
|
||
* e.g. the page size, any [class@Gtk.PrintSettings] from previous print
|
||
* operations, the number of pages, the current page, etc.
|
||
*
|
||
* Then you start the print operation by calling [method@Gtk.PrintOperation.run].
|
||
* It will then show a dialog, let the user select a printer and options.
|
||
* When the user finished the dialog, various signals will be emitted on
|
||
* the `GtkPrintOperation`, the main one being
|
||
* [signal@Gtk.PrintOperation::draw-page], which you are supposed to handle
|
||
* and render the page on the provided [class@Gtk.PrintContext] using Cairo.
|
||
*
|
||
* # The high-level printing API
|
||
*
|
||
* ```c
|
||
* static GtkPrintSettings *settings = NULL;
|
||
*
|
||
* static void
|
||
* do_print (void)
|
||
* {
|
||
* GtkPrintOperation *print;
|
||
* GtkPrintOperationResult res;
|
||
*
|
||
* print = gtk_print_operation_new ();
|
||
*
|
||
* if (settings != NULL)
|
||
* gtk_print_operation_set_print_settings (print, settings);
|
||
*
|
||
* g_signal_connect (print, "begin_print", G_CALLBACK (begin_print), NULL);
|
||
* g_signal_connect (print, "draw_page", G_CALLBACK (draw_page), NULL);
|
||
*
|
||
* res = gtk_print_operation_run (print, GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG,
|
||
* GTK_WINDOW (main_window), NULL);
|
||
*
|
||
* if (res == GTK_PRINT_OPERATION_RESULT_APPLY)
|
||
* {
|
||
* if (settings != NULL)
|
||
* g_object_unref (settings);
|
||
* settings = g_object_ref (gtk_print_operation_get_print_settings (print));
|
||
* }
|
||
*
|
||
* g_object_unref (print);
|
||
* }
|
||
* ```
|
||
*
|
||
* By default `GtkPrintOperation` uses an external application to do
|
||
* print preview. To implement a custom print preview, an application
|
||
* must connect to the preview signal. The functions
|
||
* [method@Gtk.PrintOperationPreview.render_page],
|
||
* [method@Gtk.PrintOperationPreview.end_preview] and
|
||
* [method@Gtk.PrintOperationPreview.is_selected]
|
||
* are useful when implementing a print preview.
