/**
|
||
* GtkDialog:
|
||
*
|
||
* Dialogs are a convenient way to prompt the user for a small amount
|
||
* of input.
|
||
*
|
||
* 
|
||
*
|
||
* Typical uses are to display a message, ask a question, or anything else
|
||
* that does not require extensive effort on the user’s part.
|
||
*
|
||
* The main area of a `GtkDialog` is called the "content area", and is yours
|
||
* to populate with widgets such a `GtkLabel` or `GtkEntry`, to present
|
||
* your information, questions, or tasks to the user.
|
||
*
|
||
* In addition, dialogs allow you to add "action widgets". Most commonly,
|
||
* action widgets are buttons. Depending on the platform, action widgets may
|
||
* be presented in the header bar at the top of the window, or at the bottom
|
||
* of the window. To add action widgets, create your `GtkDialog` using
|
||
* [ctor@Gtk.Dialog.new_with_buttons], or use
|
||
* [method@Gtk.Dialog.add_button], [method@Gtk.Dialog.add_buttons],
|
||
* or [method@Gtk.Dialog.add_action_widget].
|
||
*
|
||
* `GtkDialogs` uses some heuristics to decide whether to add a close
|
||
* button to the window decorations. If any of the action buttons use
|
||
* the response ID %GTK_RESPONSE_CLOSE or %GTK_RESPONSE_CANCEL, the
|
||
* close button is omitted.
|
||
*
|
||
* Clicking a button that was added as an action widget will emit the
|
||
* [signal@Gtk.Dialog::response] signal with a response ID that you specified.
|
||
* GTK will never assign a meaning to positive response IDs; these are
|
||
* entirely user-defined. But for convenience, you can use the response
|
||
* IDs in the [enum@Gtk.ResponseType] enumeration (these all have values
|
||
* less than zero). If a dialog receives a delete event, the
|
||
* [signal@Gtk.Dialog::response] signal will be emitted with the
|
||
* %GTK_RESPONSE_DELETE_EVENT response ID.
|
||
*
|
||
* Dialogs are created with a call to [ctor@Gtk.Dialog.new] or
|
||
* [ctor@Gtk.Dialog.new_with_buttons]. The latter is recommended; it allows
|
||
* you to set the dialog title, some convenient flags, and add buttons.
|
||
*
|
||
* A “modal” dialog (that is, one which freezes the rest of the application
|
||
* from user input), can be created by calling [method@Gtk.Window.set_modal]
|
||
* on the dialog. When using [ctor@Gtk.Dialog.new_with_buttons], you can also
|
||
* pass the %GTK_DIALOG_MODAL flag to make a dialog modal.
|
||
*
|
||
* For the simple dialog in the following example, a [class@Gtk.MessageDialog]
|
||
* would save some effort. But you’d need to create the dialog contents manually
|
||
* if you had more than a simple message in the dialog.
|
||
*
|
||
* An example for simple `GtkDialog` usage:
|
||
*
|
||
* ```c
|
||
* // Function to open a dialog box with a message
|
||
* void
|
||
* quick_message (GtkWindow *parent, char *message)
|
||
* {
|
||
* GtkWidget *dialog, *label, *content_area;
|
||
* GtkDialogFlags flags;
|
||
*
|
||
* // Create the widgets
|
||
* flags = GTK_DIALOG_DESTROY_WITH_PARENT;
|
||
* dialog = gtk_dialog_new_with_buttons ("Message",
|
||
* parent,
|
||
* flags,
|
||
* _("_OK"),
|
||
* GTK_RESPONSE_NONE,
|
||
* NULL);
|
||
* content_area = gtk_dialog_get_content_area (GTK_DIALOG (dialog));
|
||
* label = gtk_label_new (message);
|
||
*
|
||
* // Ensure that the dialog box is destroyed when the user responds
|
||
*
|
||
* g_signal_connect_swapped (dialog,
|
||
* "response",
|
||
* G_CALLBACK (gtk_window_destroy),
|
||
* dialog);
|
||
*
|
||
* // Add the label, and show everything we’ve added
|
||
*
|
||
* gtk_box_append (GTK_BOX (content_area), label);
|
||
* gtk_widget_show (dialog);
|
||
* }
|
||
* ```
|
||
*
|
||
* # GtkDialog as GtkBuildable
|
||
*
|
||
* The `GtkDialog` implementation of the `GtkBuildable` interface exposes the
|
||
* @content_area as an internal child with the name “content_area”.
|
||
*
|
||
* `GtkDialog` supports a custom `<action-widgets>` element, which can contain
|
||
* multiple `<action-widget>` elements. The “response” attribute specifies a
|
||
* numeric response, and the content of the element is the id of widget
|
||
* (which should be a child of the dialogs @action_area). To mark a response
|
||
* as default, set the “default” attribute of the `<action-widget>` element
|
||
* to true.
|
||
*
|
||
* `GtkDialog` supports adding action widgets by specifying “action” as
|
||
* the “type” attribute of a `<child>` element. The widget will be added
|
||
* either to the action area or the headerbar of the dialog, depending
|
||
* on the “use-header-bar” property. The response id has to be associated
|
||
* with the action widget using the `<action-widgets>` element.
|
||
*
|
||
* An example of a `GtkDialog` UI definition fragment:
|
||
*
|
||
* ```xml
|
||
* <object class="GtkDialog" id="dialog1">
|
||
* <child type="action">
|
||
* <object class="GtkButton" id="button_cancel"/>
|
||
* </child>
|
||
* <child type="action">
|
||
* <object class="GtkButton" id="button_ok">
|
||
* </object>
|
||
* </child>
|
||
* <action-widgets>
|
||
* <action-widget response="cancel">button_cancel</action-widget>
|
||
* <action-widget response="ok" default="true">button_ok</action-widget>
|
||
* </action-widgets>
|
||
* </object>
|
||
* ```
|
||
*
|
||
* # Accessibility
|
||
*
|
||
* `GtkDialog` uses the %GTK_ACCESSIBLE_ROLE_DIALOG role.
