Tue Mar 6 10:45:45 2001 Owen Taylor <otaylor@redhat.com> * gtk/gtkbutton.c: Add animation of activation by, on activate, pressing the button, and adding a timeout that releases the button after 250ms or on key release and emits ::clicked. (#51501) * gtk/gtkdialog.c: Bit of a hack - for buttons in the action area, we connect to ::clicked instead of ::activate so the dialog stays up through the animation. Mon Mar 5 16:38:15 2001 Owen Taylor <otaylor@redhat.com> * gtk/gtkmenushell.c (gtk_menu_shell_enter_notify): Only check the ignore_enter flag for the menu shell that the item is actually a child of, not for attached submenus. (#51536)

* Creates a new #GtkDialog with title @title (or NULL for the default
|
|
* title; see gtk_window_set_title()) and transient parent @parent (or
|
|
* NULL for none; see gtk_window_set_transient_for()). The @flags
|
|
* argument can be used to make the dialog modal (GTK_DIALOG_MODAL)
|
|
* and/or to have it destroyed along with its transient parent
|
|
* (GTK_DIALOG_DESTROY_WITH_PARENT). After @flags, button
|
|
* text/response ID pairs should be listed, with a NULL pointer ending
|
|
* the list. Button text can be either a stock ID such as
|
|
* GTK_STOCK_BUTTON_OK, or some arbitrary text. A response ID can be
|
|
* any positive number, or one of the values in the #GtkResponseType
|
|
* enumeration. If the user clicks one of these dialog buttons,
|
|
* #GtkDialog will emit the "response" signal with the corresponding
|
|
* response ID. If a #GtkDialog receives the "delete_event" signal, it
|
|
* will emit "response" with a response ID of GTK_RESPONSE_NONE.
|
|
* However, destroying a dialog does not emit the "response" signal;
|
|
* so be careful relying on "response" when using
|
|
* the GTK_DIALOG_DESTROY_WITH_PARENT flag. Buttons are from left to right,
|
|
* so the first button in the list will be the leftmost button in the dialog.
|
|
*
|
|
* Here's a simple example:
|
|
* <programlisting>
|
|
* GtkWidget *dialog = gtk_dialog_new_with_buttons ("My dialog",
|
|
* main_app_window,
|
|
* GTK_DIALOG_MODAL | GTK_DIALOG_DESTROY_WITH_PARENT,
|
|
* GTK_STOCK_BUTTON_OK,
|
|
* GTK_RESPONSE_ACCEPT,
|
|
* GTK_STOCK_BUTTON_CANCEL,
|
|
* GTK_RESPONSE_REJECT,
|
|
* NULL);
|
|
* </programlisting>
|
|
*
|
|
* Return value: a new #GtkDialog

|
|
*
|
|
* Blocks in a recursive main loop until the @dialog either emits the
|
|
* response signal, or is destroyed. If the dialog is destroyed,
|
|
* gtk_dialog_run() returns GTK_RESPONSE_NONE. Otherwise, it returns
|
|
* the response ID from the "response" signal emission. Before
|
|
* entering the recursive main loop, gtk_dialog_run() calls
|
|
* gtk_widget_show() on the dialog for you. Note that you still
|
|
* need to show any children of the dialog yourself.
|
|
*
|
|
* During gtk_dialog_run(), the default behavior of "delete_event" is
|
|
* disabled; if the dialog receives "delete_event", it will not be
|
|
* destroyed as windows usually are, and gtk_dialog_run() will return
|
|
* GTK_RESPONSE_DELETE_EVENT. Also, during gtk_dialog_run() the dialog will be
|
|
* modal. You can force gtk_dialog_run() to return at any time by
|
|
* calling gtk_dialog_response() to emit the "response"
|
|
* signal. Destroying the dialog during gtk_dialog_run() is a very bad
|
|
* idea, because your 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.
|
|
*
|
|
* Typical usage of this function might be:
|
|
* <programlisting>
|
|
* gint result = gtk_dialog_run (GTK_DIALOG (dialog));
|
|
* switch (result)
|
|
* {
|
|
* case GTK_RESPONSE_ACCEPT:
|
|
* do_application_specific_something ();
|
|
* break;
|
|
* default:
|
|
* do_nothing_since_dialog_was_cancelled ();
|
|
* break;
|
|
* }
|
|
* gtk_widget_destroy (dialog);
|
|
* </programlisting>
|
|
*
|
|
* Return value: response ID
