AUI_CONTROL enhancement: hover/context menus, associated with image controls—and later extended to any static text controls in 6.1.1371.0—may now contain submenus. To indicate the start of a submenu, set the command string for the parent item to "[SUB]". To indicate the end of a submenu, define a dummy menu item whose text is "[ENDSUB]" and whose command field will be ignored.
For example, to define a two level hover/context menu similar to the following:
Item 1
Item 2 > Sub-Item 1a
Sub-Item 1b
Item 3
Item 4 > Sub-Item 2a
Sub-Item 2b
The definition string in the tooltip parameter should be coded something like:
TOOLTIP$ = ">tooltip string\" &
+ "Item 1,VK_xF101;Item 2,[SUB];" &
+ "Sub-Item 1a,VK_xF201;Sub-Item 1b,VK_xF202;[ENDSUB],;" &
+ "Item 3,VK_xF103;Item 4,[SUB];" &
+ "Sub-Item 2a,VK_xF301;Sub-Item 2b,VK_xF302;[ENDSUB],;"
Sub menus may be nested up to nine levels deep, and a single hover/context menu may contain up to 99 total sub menus.
