Remove a boatload of "or %NULL" from nullable parameters and return values. gi-docgen generates suitable text from the annotation that we don't need to duplicate. This adds a few missing nullable annotations too.

/**
|
||
* GtkMessageDialog:
|
||
*
|
||
* `GtkMessageDialog` presents a dialog with some message text.
|
||
*
|
||
* 
|
||
*
|
||
* It’s simply a convenience widget; you could construct the equivalent of
|
||
* `GtkMessageDialog` from `GtkDialog` without too much effort, but
|
||
* `GtkMessageDialog` saves typing.
|
||
*
|
||
* The easiest way to do a modal message dialog is to use the %GTK_DIALOG_MODAL
|
||
* flag, which will call [method@Gtk.Window.set_modal] internally. The dialog will
|
||
* prevent interaction with the parent window until it's hidden or destroyed.
|
||
* You can use the [signal@Gtk.Dialog::response] signal to know when the user
|
||
* dismissed the dialog.
|
||
*
|
||
* An example for using a modal dialog:
|
||
* ```c
|
||
* GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT | GTK_DIALOG_MODAL;
|
||
* dialog = gtk_message_dialog_new (parent_window,
|
||
* flags,
|
||
* GTK_MESSAGE_ERROR,
|
||
* GTK_BUTTONS_CLOSE,
|
||
* "Error reading “%s”: %s",
|
||
* filename,
|
||
* g_strerror (errno));
|
||
* // Destroy the dialog when the user responds to it
|
||
* // (e.g. clicks a button)
|
||
*
|
||
* g_signal_connect (dialog, "response",
|
||
* G_CALLBACK (gtk_window_destroy),
|
||
* NULL);
|
||
* ```
|
||
*
|
||
* You might do a non-modal `GtkMessageDialog` simply by omitting the
|
||
* %GTK_DIALOG_MODAL flag:
|
||
*
|
||
* ```c
|
||
* GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT;
|
||
* dialog = gtk_message_dialog_new (parent_window,
|
||
* flags,
|
||
* GTK_MESSAGE_ERROR,
|
||
* GTK_BUTTONS_CLOSE,
|
||
* "Error reading “%s”: %s",
|
||
* filename,
|
||
* g_strerror (errno));
|
||
*
|
||
* // Destroy the dialog when the user responds to it
|
||
* // (e.g. clicks a button)
|
||
* g_signal_connect (dialog, "response",
|
||
* G_CALLBACK (gtk_window_destroy),
|
||
* NULL);
|
||
* ```
|
||
*
|
||
* # GtkMessageDialog as GtkBuildable
|
||
*
|
||
* The `GtkMessageDialog` implementation of the `GtkBuildable` interface exposes
|
||
* the message area as an internal child with the name “message_area”.

|

* Creates a new message dialog.
|
||
*
|
||
* This is a simple dialog with some text that is marked up with
|
||
* Pango markup. When the user clicks a button a “response” signal
|
||
* is emitted with response IDs from [enum@Gtk.ResponseType]. See
|
||
* [class@Gtk.Dialog] for more details.
|
||
*
|
||
* Special XML characters in the printf() arguments passed to this
|
||
* function will automatically be escaped as necessary.
|
||
* (See g_markup_printf_escaped() for how this is implemented.)
|
||
* Usually this is what you want, but if you have an existing
|
||
* Pango markup string that you want to use literally as the
|
||
* label, then you need to use [method@Gtk.MessageDialog.set_markup]
|
||
* instead, since you can’t pass the markup string either
|
||
* as the format (it might contain “%” characters) or as a string
|
||
* argument.
|
||
*
|
||
* ```c
|
||
* GtkWidget *dialog;
|
||
* GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT;
|
||
* dialog = gtk_message_dialog_new (parent_window,
|
