/**
|
|
* 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
|
|
* <structfield>action_area</structfield>. 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.
|
|
* <example>
|
|
* <title>Simple GtkDialog usage</title>
|
|
* <programlisting>
|
|
* /* Function to open a dialog box displaying the message provided. */

* "action_area".
|
|
* </para>
|
|
* <para>
|
|
* 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).

|
* (#GTK_DIALOG_DESTROY_WITH_PARENT). After @flags, button

|
|
* However, destroying a dialog does not emit the ::response signal;
|
|
* so be careful relying on ::response when using the

* After gtk_dialog_run() returns, you are responsible for hiding or

* destroying the dialog if you wish to do so.

|
* 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, <emphasis>will</emphasis>
