Description
Specifies the index of the display that shows the pop-up form.
Specifies the index of the display in the Displays array that shows the current pop-up form.
PreferedDisplayIndex is used for context menus. When an application opens several submenus of context menus, all these submenus should be shown on the same display, even if a new pop-up submenu can be shown on a neighbor display.
If a specified PreferedDisplayIndex does not exist, then a pop-up form is shown on a display that is the closest to the place where the form should appear according to all specified positioning parameters Placement, PlacementTarget, and PlacementRectangle.
