Expand description

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

An example GtkDialog

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 Dialog is called the “content area”, and is yours to populate with widgets such a Label or 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 Dialog using with_buttons(), or use DialogExt::add_button(), DialogExtManual::add_buttons(), or DialogExt::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 ResponseType::Close or ResponseType::Cancel, the close button is omitted.

Clicking a button that was added as an action widget will emit the 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 ResponseType enumeration (these all have values less than zero). If a dialog receives a delete event, the response signal will be emitted with the ResponseType::DeleteEvent response ID.

Dialogs are created with a call to new() or 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 GtkWindowExt::set_modal() on the dialog. When using with_buttons(), you can also pass the DialogFlags::MODAL flag to make a dialog modal.

For the simple dialog in the following example, a 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 Dialog usage:

⚠️ The following code is in 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 Dialog implementation of the Buildable interface exposes the @content_area as an internal child with the name “content_area”.

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.

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 Dialog UI definition fragment:

<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

Dialog uses the AccessibleRole::Dialog role.

Properties

use-header-bar

true if the dialog uses a headerbar for action buttons instead of the action-area.

For technical reasons, this property is declared as an integer property, but you should only set it to true or false.

Creating a dialog with headerbar

Builtin Dialog subclasses such as ColorChooserDialog set this property according to platform conventions (using the gtk-dialogs-use-header setting).

Here is how you can achieve the same:

⚠️ The following code is in c ⚠️

g_object_get (settings, "gtk-dialogs-use-header", &header, NULL);
dialog = g_object_new (GTK_TYPE_DIALOG, header, TRUE, NULL);

Signals

close

Emitted when the user uses a keybinding to close the dialog.

This is a keybinding signal.

The default binding for this signal is the Escape key.

Action

response

Emitted when an action widget is clicked.

The signal is also emitted when the dialog receives a delete event, and when DialogExt::response() is called. On a delete event, the response ID is ResponseType::DeleteEvent. Otherwise, it depends on which action widget was clicked.

Window

activate-default

Emitted when the user activates the default widget of @window.

This is a keybinding signal.

Action

activate-focus

Emitted when the user activates the currently focused widget of @window.

This is a keybinding signal.

Action

close-request

Emitted when the user clicks on the close button of the window.

enable-debugging

Emitted when the user enables or disables interactive debugging.

When @toggle is true, interactive debugging is toggled on or off, when it is false, the debugger will be pointed at the widget under the pointer.

This is a keybinding signal.

The default bindings for this signal are Ctrl-Shift-I and Ctrl-Shift-D.

Action

keys-changed

emitted when the set of accelerators or mnemonics that are associated with @window changes.

Widget

destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

direction-changed

Emitted when the text direction of a widget changes.

hide

Emitted when @widget is hidden.

keynav-failed

Emitted if keyboard navigation fails.

See WidgetExt::keynav_failed() for details.

map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering “above” @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

realize

Emitted when @widget is associated with a gdk::Surface.

This means that WidgetExt::realize() has been called or the widget has been mapped (that is, it is going to be drawn).

show

Emitted when @widget is shown.

state-flags-changed

Emitted when the widget state changes.

See WidgetExt::state_flags().

unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

unrealize

Emitted when the gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).

source

pub fn builder() -> DialogBuilder

👎Deprecated: Since 4.10

Creates a new builder-pattern struct instance to construct Dialog objects.

This method returns an instance of DialogBuilder which can be used to create Dialog objects.

source§

impl Dialog

source

pub fn with_buttons<T: IsA<Window>>( title: impl IntoOptionalGStr, parent: Option<&T>, flags: DialogFlags, buttons: &[(&str, ResponseType)] ) -> Self

👎Deprecated: Since 4.10

Creates a new Dialog with the given title and transient parent.

The @flags argument can be used to make the dialog modal, have it destroyed along with its transient parent, or make it use a headerbar.

Button text/response ID pairs should be listed in pairs, with a None pointer ending the list. Button text can be arbitrary text. A response ID can be any positive number, or one of the values in the ResponseType enumeration. If the user clicks one of these buttons, Dialog will emit the response signal with the corresponding response ID.

If a Dialog receives a delete event, it will emit ::response with a response ID of ResponseType::DeleteEvent.

However, destroying a dialog does not emit the ::response signal; so be careful relying on ::response when using the DialogFlags::DESTROY_WITH_PARENT flag.

Here’s a simple example: ⚠️ The following code is in c ⚠️

GtkWindow *main_app_window; // Window the dialog should show up on
GtkWidget *dialog;
GtkDialogFlags flags = GTK_DIALOG_MODAL | GTK_DIALOG_DESTROY_WITH_PARENT;
dialog = gtk_dialog_new_with_buttons ("My dialog",
                                      main_app_window,
                                      flags,
                                      _("_OK"),
                                      GTK_RESPONSE_ACCEPT,
                                      _("_Cancel"),
                                      GTK_RESPONSE_REJECT,
                                      NULL);
