1.97.2 Instance variables

menu_bar-button: button_name*

Name of the button (see event<-button) that caused the first menu to appear. Used internally.

menu_bar <- buttons: chain

Chain holding button objects to represent each of the entries. When a popup object is menu_bar->append’ed, a button is added to this chain to visualise the popup. The button<-popup slot refers to the popup.

This implementation allows for easy emulation of the OpenLook look-and-feel style as OpenLook does not define menu-bars.

menu_bar <- current: popup*

Currently visible popup object or @nil if the menu_bar is inactive

menu_bar <- format: {left,center,right}

Describes how the labels are formatted in their boxes. See also graphical->pen and dialog_item->label_font.

dialog_item->label_font

dialog_item <- label_font: font*

@see menu_bar.label_font @see dialog_item->label_font

menu_bar <- members: chain

Chain of popup objects, in the order they appear on the bar. The bar itself draws from menu_bar<-buttons; this chain is what a native menu bar is built from and what menu_bar->key steps through. menu_bar->append keeps the two in step.
