The GTK+ widgets used by an Emacs frame are listed below:

Emacs (class GtkWindow)

@table @asis

pane (class GtkVBox)

@table @asis

menubar (class GtkMenuBar)

@table @asis

[menu item widgets]

@item [unnamed widget] (class GtkHandleBox)

emacs-toolbar (class GtkToolbar)

@table @asis

[tool bar item widgets]

@end table @item emacs (class GtkFixed)

verticalScrollBar (class GtkVScrollbar)

@end table @end table @end table @noindent The contents of Emacs windows are drawn in the emacs widget. Note that even if there are multiple Emacs windows, each scroll bar widget is named verticalScrollBar. For example, here are two different ways to set the menu bar style:

widget "Emacs.pane.menubar.*" style "my_style"
widget_class "GtkWindow.GtkVBox.GtkMenuBar.*" style "my_style"

For GTK+ dialogs, Emacs uses a widget named emacs-dialog, of class GtkDialog. For file selection, Emacs uses a widget named emacs-filedialog, of class GtkFileSelection. Because the widgets for pop-up menus and dialogs are free-standing windows and not contained in the Emacs widget, their GTK+ absolute names do not start with Emacs. To customize these widgets, use wildcards like this:

widget "*emacs-dialog*" style "my_dialog_style"
widget "*emacs-filedialog* style "my_file_style"
widget "*emacs-menuitem* style "my_menu_style"

If you want to apply a style to all menus in Emacs, use this:

widget_class "*Menu*" style "my_menu_style"
