class Gtk::Dialog

Overview

Dialogs are a convenient way to prompt the user for a small amount of input.

An example Gtk::Dialog

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 Gtk::Dialog is called the "content area", and is yours to populate with widgets such a Gtk::Label or Gtk::Entry, 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 Gtk::Dialog using Gtk::Dialog#new_with_buttons, or use Gtk::Dialog#add_button, Gtk::Dialog#add_buttons, or Gtk::Dialog#add_action_widget.

Gtk::Dialogs 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 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 Gtk::ResponseType enumeration (these all have values less than zero). If a dialog receives a delete event, the Gtk::Dialog::#response signal will be emitted with the %GTK_RESPONSE_DELETE_EVENT response ID.

Dialogs are created with a call to Gtk::Dialog.new or 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 Gtk::Window#modal= on the dialog. When using 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 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 Gtk::Dialog usage:

WARNING ⚠️ The following code is in c ⚠️

// Function to open a dialog box with a message
void
quick_message (Gtk::Window *parent, char *message)
{
 Gtk::Widget *dialog, *label, *content_area;
 Gtk::DialogFlags 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);
}

Gtk::Dialog as Gtk::Buildable

The Gtk::Dialog implementation of the Gtk::Buildable interface exposes the content_area as an internal child with the name “content_area”.

Gtk::Dialog 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.

Gtk::Dialog 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 Gtk::Dialog UI definition fragment:

WARNING ⚠️ The following code is in xml ⚠️

<object class="Gtk::Dialog" id="dialog1">
  <child type="action">
    <object class="Gtk::Button" id="button_cancel"/>
  </child>
  <child type="action">
    <object class="Gtk::Button" 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

Gtk::Dialog uses the %GTK_ACCESSIBLE_ROLE_DIALOG role.

def self.new : self #

Creates a new dialog box.

Widgets should not be packed into the Gtk::Window directly, but into the content_area and action_area, as described above.

Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def add_action_widget(child : Gtk::Widget, response_id : Int32) : Nil #

Adds an activatable widget to the action area of a Gtk::Dialog.

GTK connects a signal handler that will emit the Gtk::Dialog::#response signal on the dialog when the widget is activated. The widget is appended to the end of the dialog’s action area.

If you want to add a non-activatable widget, simply pack it into the action_area field of the Gtk::Dialog struct.


[View source]
def add_button(button_text : String, response_id : Int32) : Gtk::Widget #

Adds a button with the given text.

GTK arranges things so that clicking the button will emit the Gtk::Dialog::#response signal with the given response_id. The button is appended to the end of the dialog’s action area. The button widget is returned, but usually you don’t need it.


[View source]
def close_signal #

[View source]
def content_area : Gtk::Box #

Returns the content area of dialog.


[View source]
def default_response=(response_id : Int32) : Nil #

Sets the default widget for the dialog based on the response ID.

Pressing “Enter” normally activates the default widget.


[View source]
def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def header_bar : Gtk::HeaderBar #

Returns the header bar of dialog.

Note that the headerbar is only used by the dialog if the [property@Gtk.Dialog:use-header-bar] property is true.


[View source]
def response(response_id : Int32) : Nil #

Emits the ::response signal with the given response ID.

Used to indicate that the user has responded to the dialog in some way.


[View source]
def response_for_widget(widget : Gtk::Widget) : Int32 #

Gets the response id of a widget in the action area of a dialog.


[View source]
def response_signal #

[View source]
def set_response_sensitive(response_id : Int32, setting : Bool) : Nil #

A convenient way to sensitize/desensitize dialog buttons.

Calls gtk_widget_set_sensitive (widget, *setting*) for each widget in the dialog’s action area with the given response_id.


[View source]
def use_header_bar : Int32 #

[View source]
def use_header_bar=(value : Int32) : Int32 #

[View source]
def widget_for_response(response_id : Int32) : Gtk::Widget | Nil #

Gets the widget button that uses the given response ID in the action area of a dialog.
