To build a better world sometimes means having to tear the old one down.
-- Alexander Pierce, "Captain America: The Winter Soldier"
ATK served us well for nearly 20 years, but the world has changed, and
GTK has changed with it. Now ATK is mostly a hindrance towards improving
the accessibility stack:
- it maps to a very specific implementation, AT-SPI, which is Linux and
Unix specific
- it requires implementing the same functionality in three different
layers of the stack: AT-SPI, ATK, and GTK
- only GTK uses it; every other Linux and Unix toolkit and application
talks to AT-SPI directly, including assistive technologies
Sadly, we cannot incrementally port GTK to a new accessibility stack;
since ATK insulates us entirely from the underlying implementation, we
cannot replace it piecemeal. Instead, we're going to remove everything
and then incrementally build on a clean slate:
- add an "accessible" interface, implemented by GTK objects directly,
which describe the accessible role and state changes for every UI
element
- add an "assistive technology context" to proxy a native accessibility
API, and assign it to every widget
- implement the AT context depending on the platform

* @Short_description: A convenient message window
|

* @Title: GtkMessageDialog
|
||
* @See_also:#GtkDialog
|
||
*
|
||
* #GtkMessageDialog presents a dialog with some message text. It’s simply a
|
||
* convenience widget; you could construct the equivalent of #GtkMessageDialog
|
||
* from #GtkDialog without too much effort, but #GtkMessageDialog saves typing.
|
||
*
|
||
* The easiest way to do a modal message dialog is to use the %GTK_DIALOG_MODAL
|
||
* flag, which will call gtk_window_set_modal() internally. The dialog will
|
||
* prevent interaction with the parent window until it's hidden or destroyed.
|
||
* You can use the #GtkDialog::response signal to know when the user dismissed
|
||
* the dialog.
|
||
*
|
||
* An example for using a modal dialog:
|
||
* |[<!-- language="C" -->
|
||
* GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT | GTK_DIALOG_MODAL;
|
||
* dialog = gtk_message_dialog_new (parent_window,
|
||
* flags,
|
||
* GTK_MESSAGE_ERROR,
|
||
* GTK_BUTTONS_CLOSE,
|
||
* "Error reading “%s”: %s",
|
||
* filename,
|
||
* g_strerror (errno));
|
||
* // Destroy the dialog when the user responds to it
|
||
* // (e.g. clicks a button)
|
||
*
|
||
* g_signal_connect (dialog, "response",
|
||
* G_CALLBACK (gtk_window_destroy),
|
||
* NULL);
|
||
* ]|
|
||
*
|
||
* You might do a non-modal #GtkMessageDialog simply by omitting the
|
||
* %GTK_DIALOG_MODAL flag:
|
||
*
|
||
* |[<!-- language="C" -->
|
||
* GtkDialogFlags flags = GTK_DIALOG_DESTROY_WITH_PARENT;
|
||
* dialog = gtk_message_dialog_new (parent_window,
|
||
* flags,
|
||
* GTK_MESSAGE_ERROR,
|
||
* GTK_BUTTONS_CLOSE,
|
||
* "Error reading “%s”: %s",
|
||
* filename,
|
||
* g_strerror (errno));
|
||
*
|
||
* // Destroy the dialog when the user responds to it
|
||
* // (e.g. clicks a button)
|
||
* g_signal_connect (dialog, "response",
|
||
* G_CALLBACK (gtk_window_destroy),
|
||
* NULL);
|
||
* ]|
|
||
*
|
||
* # GtkMessageDialog as GtkBuildable
|
||
*
|
||
* The GtkMessageDialog implementation of the GtkBuildable interface exposes
|
||
* the message area as an internal child with the name “message_area”.
