The GVariant we are getting here might not be coming from GTK+, but rather from some other source. Best to be forgiving and deal with missing data without crashing. This was causing the GTK+ portal backends to crash on print requests from Qt.

|
* @Short_description: Stores page setup information
|
|
* @Title: GtkPageSetup
|
|
*
|
|
* A GtkPageSetup object stores the page size, orientation and margins.
|
|
* The idea is that you can get one of these from the page setup dialog
|
|
* and then pass it to the #GtkPrintOperation when printing.
|
|
* The benefit of splitting this out of the #GtkPrintSettings is that
|
|
* these affect the actual layout of the page, and thus need to be set
|
|
* long before user prints.
|
|
*
|
|
* ## Margins ## {#print-margins}
|
|
* The margins specified in this object are the “print margins”, i.e. the
|
|
* parts of the page that the printer cannot print on. These are different
|
|
* from the layout margins that a word processor uses; they are typically
|
|
* used to determine the minimal size for the layout
|
|
* margins.
|
|
*
|
|
* To obtain a #GtkPageSetup use gtk_page_setup_new() to get the defaults,
|
|
* or use gtk_print_run_page_setup_dialog() to show the page setup dialog
|
|
* and receive the resulting page setup.
