| /* |
| * All JMenuItems (and JMenus) include enough space for the insets |
| * plus one or more elements. When we say "icon(s)" below, we mean |
| * "check/radio indicator and/or user icon." If both are defined for |
| * a given menu item, then in a LTR orientation the check/radio indicator |
| * is on the left side followed by the user icon to the right; it is |
| * just the opposite in a RTL orientation. |
| * |
| * Cases to consider for SynthMenuItemUI (visualized here in a |
| * LTR orientation; the RTL case would be reversed): |
| * text |
| * icon(s) + text |
| * icon(s) + text + accelerator |
| * text + accelerator |
| * |
| * Cases to consider for SynthMenuUI (again visualized here in a |
| * LTR orientation): |
| * text + arrow |
| * (user)icon + text + 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. |
| * |
| * A quick note about how preferred sizes are calculated... Generally |
| * speaking, SynthPopupMenuUI will run through the list of its children |
| * (from top to bottom) and ask each for its preferred size. Each menu |
| * item will add up the max width of each element (icons, text, |
| * accelerator spacing, accelerator text or arrow icon) encountered thus |
| * far, so by the time all menu items have been calculated, we will |
| * know the maximum (preferred) menu item size for that popup menu. |
| * Later when it comes time to paint each menu item, we can use those |
| * same accumulated max element sizes in order to layout the item. |
