## Description

## Details

### struct GnomeDialogPrivate

    struct GnomeDialogPrivate;

### gnome_dialog_new ()

    GtkWidget*  gnome_dialog_new                (const gchar *title,
                                                 ...);

Creates a new GnomeDialog, with the given title, and any button names in the arg list. Buttons can be simple names, such as _("My Button"), or gnome-stock defines such as `GNOME_STOCK_BUTTON_OK`, etc. The last argument should be NULL to terminate the list.

Buttons passed to this function are numbered from left to right, starting with 0. So the first button in the arglist is button 0, then button 1, etc. These numbers are used throughout the GnomeDialog API.

`title` : | The title of the dialog; appears in window titlebar.
`...` : | NULL-terminated varargs list of button names or GNOME_STOCK_BUTTON_* defines.
Returns : | The new GnomeDialog.

### gnome_dialog_newv ()

    GtkWidget*  gnome_dialog_newv               (const gchar *title,
                                                 const gchar **buttons);

See gnome_dialog_new(), this function is identical but does not use varargs.

`title` : | Title of the dialog.
`buttons` : | NULL-terminated vector of buttons names.
Returns : | The new GnomeDialog.

### gnome_dialog_set_parent ()

    void        gnome_dialog_set_parent         (GnomeDialog *dialog,
                                                 GtkWindow *parent);

Dialogs have "parents," usually the main application window which spawned them. This function will let the window manager know about the parent-child relationship. Usually this means the dialog must stay on top of the parent, and will be minimized when the parent is. Gnome also allows users to request dialog placement above the parent window (vs. at the mouse position, or at a default window manger location).

`dialog` : | GnomeDialog to set the parent of.
`parent` : | Parent GtkWindow.

### gnome_dialog_button_connect ()

    void        gnome_dialog_button_connect     (GnomeDialog *dialog,
                                                 gint button,
                                                 GtkSignalFunc callback,
                                                 gpointer data);

Simply gtk_signal_connect() to the "clicked" signal of the specified button.

`dialog` : | GnomeDialog to affect.
`button` : | Button number.
`callback` : | A standard Gtk callback.
`data` : | Callback data.

### gnome_dialog_button_connect_object ()

    void        gnome_dialog_button_connect_object
                                                (GnomeDialog *dialog,
                                                 gint button,
                                                 GtkSignalFunc callback,
                                                 GtkObject *obj);

gtk_signal_connect_object() to the "clicked" signal of the given button.

`dialog` : | GnomeDialog to affect.
`button` : | Button to connect to.
`callback` : | Callback.
`obj` : | As for gtk_signal_connect_object().

### gnome_dialog_run ()

    gint        gnome_dialog_run                (GnomeDialog *dialog);

Blocks until the user clicks a button, or closes the dialog with the window manager's close decoration (or by pressing Escape).

You need to set up the dialog to do the right thing when a button is clicked or delete_event is received; you must consider both of those possibilities so that you know the status of the dialog when gnome_dialog_run() returns. A common mistake is to forget about Escape and the window manager close decoration; by default, these call gnome_dialog_close(), which by default destroys the dialog. If your button clicks do not destroy the dialog, you don't know whether the dialog is destroyed when gnome_dialog_run() returns. This is bad.

So you should either close the dialog on button clicks as well, or change the gnome_dialog_close() behavior to hide instead of destroy. You can do this with gnome_dialog_close_hides().

`dialog` : | GnomeDialog to use.
Returns : | If a button was pressed, the button number is returned. If not, -1 is returned.

### gnome_dialog_run_and_close ()

    gint        gnome_dialog_run_and_close      (GnomeDialog *dialog);

See gnome_dialog_run(). The only difference is that this function calls gnome_dialog_close() before returning, if the dialog was not already closed.

`dialog` : | GnomeDialog to use.
Returns : | If a button was pressed, the button number. Otherwise -1.

### gnome_dialog_set_default ()

    void        gnome_dialog_set_default        (GnomeDialog *dialog,
                                                 gint button);

The default button will be activated if the user just presses return. Usually you should make the least-destructive button the default. Otherwise, the most commonly-used button.

`dialog` : | GnomeDialog to affect.
`button` : | Number of the default button.

### gnome_dialog_grab_focus ()

    void        gnome_dialog_grab_focus         (GnomeDialog *dialog,
                                                 gint button);

The button `button` will grab the focus. Use this for dialogs Where only buttons are displayed and you want to change the default button.

`dialog` : | GnomeDialog to affect.
`button` : | Number of the default button.

### gnome_dialog_set_sensitive ()

    void        gnome_dialog_set_sensitive      (GnomeDialog *dialog,
                                                 gint button,
                                                 gboolean setting);

Calls gtk_widget_set_sensitive() on the specified button number.

`dialog` : | GnomeDialog to affect.
`button` : | Which button to affect.
`setting` : | TRUE means it's sensitive.

### gnome_dialog_set_accelerator ()

    void        gnome_dialog_set_accelerator    (GnomeDialog *dialog,
                                                 gint button,
                                                 const guchar accelerator_key,
                                                 guint8 accelerator_mods);

`dialog` : | GnomeDialog to affect.
`button` : | Button number.
`accelerator_key` : | Key for the accelerator.
`accelerator_mods` : | Modifier.

### gnome_dialog_close ()

    void        gnome_dialog_close              (GnomeDialog *dialog);

See also gnome_dialog_close_hides(). This function emits the "close" signal, which either hides or destroys the dialog (destroy by default). If you connect to the "close" signal, and your callback returns TRUE, the hide or destroy will be blocked. You can do this to avoid closing the dialog if the user gives invalid input, for example.

Using gnome_dialog_close() in place of gtk_widget_hide() or gtk_widget_destroy() allows you to easily catch all sources of dialog closure, including delete_event and button clicks, and handle them in a central location.

`dialog` : | GnomeDialog to close.

### gnome_dialog_close_hides ()

    void        gnome_dialog_close_hides        (GnomeDialog *dialog,
                                                 gboolean just_hide);

Some dialogs are expensive to create, so you want to keep them around and just gtk_widget_show() them when they are opened, and gtk_widget_hide() them when they're closed. Other dialogs are expensive to keep around, so you want to gtk_widget_destroy() them when they're closed. It's a judgment call you will need to make for each dialog.

`dialog` : | GnomeDialog to affect.
`just_hide` : | If TRUE, gnome_dialog_close() calls gtk_widget_hide() instead of gtk_widget_destroy().

### gnome_dialog_set_close ()

    void        gnome_dialog_set_close          (GnomeDialog *dialog,
                                                 gboolean click_closes);

This is a convenience function so you don't have to connect callbacks to each button just to close the dialog. By default, GnomeDialog has this parameter set the FALSE and it will not close on any click. (This was a design error.) However, almost all the GnomeDialog subclasses, such as GnomeMessageBox and GnomePropertyBox, have this parameter set to TRUE by default.

`dialog` : | GnomeDialog to affect.
`click_closes` : | TRUE if clicking any button should call gnome_dialog_close().

### gnome_dialog_editable_enters ()

    void        gnome_dialog_editable_enters    (GnomeDialog *dialog,
                                                 GtkEditable *editable);

Normally if there's an editable widget (such as GtkEntry) in your dialog, pressing Enter will activate the editable rather than the default dialog button. However, in most cases, the user expects to type something in and then press enter to close the dialog. This function enables that behavior.

`dialog` : | GnomeDialog to affect.
`editable` : | Editable to affect.

### gnome_dialog_append_buttons ()

    void        gnome_dialog_append_buttons     (GnomeDialog *dialog,
                                                 const gchar *first,
                                                 ...);

This function is mostly for internal library use. You should use gnome_dialog_new() instead. See that function for a description of the button arguments.

`dialog` : | GnomeDialog to add buttons to.
`first` : | First button to add.
`...` : | varargs list of additional buttons, NULL-terminated.

### gnome_dialog_append_button ()

    void        gnome_dialog_append_button      (GnomeDialog *dialog,
                                                 const gchar *name);

This function is mostly for internal library use. You should use gnome_dialog_new() instead. See that function for a description of the button argument.

`dialog` : | GnomeDialog to add button to.
`name` : |

### gnome_dialog_append_buttonsv ()

    void        gnome_dialog_append_buttonsv    (GnomeDialog *dialog,
                                                 const gchar **buttons);

For internal use, language bindings, etc. Use gnome_dialog_new() instead.

`dialog` : | GnomeDialog to append to.
`buttons` : | NULL-terminated vector of buttons to append.

### gnome_dialog_append_button_with_pixmap ()

    void        gnome_dialog_append_button_with_pixmap
                                                (GnomeDialog *dialog,
                                                 const gchar *name,
                                                 const gchar *pixmap);

gnome_dialog_new() does not permit custom buttons with pixmaps, so if you want one of those you need to use this function.

`dialog` : | GnomeDialog to add the button to.
`name` : |
`pixmap` : |

### gnome_dialog_append_buttons_with_pixmaps ()

    void        gnome_dialog_append_buttons_with_pixmaps
                                                (GnomeDialog *dialog,
                                                 const gchar **names,
                                                 const gchar **pixmaps);

Simply calls gnome_dialog_append_button_with_pixmap() repeatedly.

`dialog` : | GnomeDialog to append to.
`names` : | NULL-terminated vector of button names.
`pixmaps` : | NULL-terminated vector of pixmap names.

### gnome_dialog_construct ()

    void        gnome_dialog_construct          (GnomeDialog *dialog,
                                                 const gchar *title,
                                                 va_list ap);
