If the widget is an action widget, it's been previously added with gtk_dialog_add_action_widget, which calls add_response_data on it, which in turn connects to the clicked/activate signal of that widget, so we don't need to connect to that signal a second time in gtk_buildable_custom_finished.

/**
|
||
* SECTION:gtkdialog
|
||
* @Short_description: Create popup windows
|
||
* @Title: GtkDialog
|
||
* @See_also: #GtkVBox, #GtkWindow, #GtkButton
|
||
*
|
||
* Dialog boxes are a convenient way to prompt the user for a small amount
|
||
* of input, e.g. to display a message, ask a question, or anything else
|
||
* that does not require extensive effort on the user’s part.
|
||
*
|
||
* GTK+ treats a dialog as a window split vertically. The top section is a
|
||
* #GtkVBox, and is where widgets such as a #GtkLabel or a #GtkEntry should
|
||
* be packed. The bottom area is known as the
|
||
* “action area”. This is generally used for
|
||
* packing buttons into the dialog which may perform functions such as
|
||
* cancel, ok, or apply.
|
||
*
|
||
* #GtkDialog boxes are created with a call to gtk_dialog_new() or
|
||
* gtk_dialog_new_with_buttons(). gtk_dialog_new_with_buttons() is
|
||
* recommended; it allows you to set the dialog title, some convenient
|
||
* flags, and add simple buttons.
|
||
*
|
||
* If “dialog” is a newly created dialog, the two primary areas of the
|
||
* window can be accessed through gtk_dialog_get_content_area() and
|
||
* gtk_dialog_get_action_area(), as can be seen from the example below.
|
||
*
|
||
* A “modal” dialog (that is, one which freezes the rest of the application
|
||
* from user input), can be created by calling gtk_window_set_modal() on the
|
||
* dialog. Use the GTK_WINDOW() macro to cast the widget returned from
|
||
* gtk_dialog_new() into a #GtkWindow. When using gtk_dialog_new_with_buttons()
|
||
* you can also pass the #GTK_DIALOG_MODAL flag to make a dialog modal.
|
||
*
|
||
* If you add buttons to #GtkDialog using gtk_dialog_new_with_buttons(),
|
||
* gtk_dialog_add_button(), gtk_dialog_add_buttons(), or
|
||
* gtk_dialog_add_action_widget(), clicking the button will emit a signal
|
||
* called #GtkDialog::response 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
|
||
* #GtkResponseType enumeration (these all have values less than zero). If
|
||
* a dialog receives a delete event, the #GtkDialog::response signal will
|
||
* be emitted with a response ID of #GTK_RESPONSE_DELETE_EVENT.
|
||
*
|
||
* If you want to block waiting for a dialog to return before returning
|
||
* control flow to your code, you can call gtk_dialog_run(). This function
|
||
* enters a recursive main loop and waits for the user to respond to the
|
||
* dialog, returning the response ID corresponding to the button the user
|
||
* clicked.
|
||
*
|
||
* For the simple dialog in the following example, in reality you’d probably
|
||
* use #GtkMessageDialog to save yourself 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:
|
||
* |[<!-- language="C" -->
|
||
* // Function to open a dialog box with a message
|
||
* void
|
||
* quick_message (GtkWindow *parent, gchar *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_widget_destroy),
|
||
* dialog);
|
||
*
|
||
* // Add the label, and show everything we’ve added
|
||
*
|
||
* gtk_container_add (GTK_CONTAINER (content_area), label);
|
||
* gtk_widget_show_all (dialog);
|
||
* }
|
||
* ]|
|
||
*
|
||
* # GtkDialog as GtkBuildable
|
||
*
|
||
* The GtkDialog implementation of the #GtkBuildable interface exposes the
|
||
* @vbox and @action_area as internal children with the names “vbox” and
|
||
* “action_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:
|
||
* |[
|
||
* <object class="GtkDialog" id="dialog1">
|
||
* <child type="action">
|
||
* <object class="GtkButton" id="button_cancel"/>
|
||
* </child>
|
||
* <child type="action">
|
||
* <object class="GtkButton" id="button_ok"/>
|
||
* </child>
|
||
* <action-widgets>
|
||
* <action-widget response="cancel">button_cancel</action-widget>
|
||
* <action-widget response="ok" default="true">button_ok</action-widget>
|
||
* </action-widgets>
|
||
* </object>

* Before entering the recursive main loop, gtk_dialog_run() calls

|

|
||
* post-run code won’t know whether the dialog was destroyed or not.
|
||
*
|
||
* After gtk_dialog_run() returns, you are responsible for hiding or
|
||
* destroying the dialog if you wish to do so.
|

* |[<!-- language="C" -->

* gint result = gtk_dialog_run (GTK_DIALOG (dialog));

* Note that even though the recursive main loop gives the effect of a
|
||
* modal dialog (it prevents the user from interacting with other
|
||
* windows in the same window group while the dialog is run), callbacks
|
||
* such as timeouts, IO channel watches, DND drops, etc, will
|
||
* be triggered during a gtk_dialog_run() call.
