OpenJDK 27 · javax.swing.plaf.synth.SynthMenuItemLayoutHelper

Calculates preferred size and layouts synth menu items. All JMenuItems (and JMenus) include enough space for the insets plus one or more elements. When we say "label" below, we mean "icon and/or text." Cases to consider for SynthMenuItemUI (visualized here in a LTR orientation; the RTL case would be reversed): label check icon + label check icon + label + accelerator label + accelerator Cases to consider for SynthMenuUI (again visualized here in a LTR orientation): label + arrow Note that in the above scenarios, accelerator and arrow icon are mutually exclusive. This means that if a popup menu contains a mix of JMenus and JMenuItems, we only need to allow enough space for max(maxAccelerator, maxArrow), and both accelerators and arrow icons can occupy the same "column" of space in the menu.
