33 * If keyboard navigation is enabled, the keyboard may be used to navigate
34 * the menuitems on the popup. Enabling keyboard navigation is the default
35 * behaviour and will install capturing key event listeners on the popup
36 * that do not propagate key events to the contents. If you wish to place
37 * elements in a popup which accept key events, such as textboxes, keyboard
38 * navigation should be disabled.
40 * Setting ignorekeys="true" on the popup element also disables keyboard
41 * navigation, and is recommended over calling this method.

49 void enableRollup(boolean enableRollup);
52 * Control whether the event that caused the popup to be automatically
53 * dismissed ("rolled up") should be consumed, or dispatched as a
54 * normal event. This should be set immediately before calling showPopup()
55 * if non-default behavior is desired.

68 * Move the popup to a point on screen in CSS pixels.
70 void moveTo(long left, long top);
73 * Open the popup relative to a specified node at a specific location.
75 * The popup may be either anchored to another node or opened freely.
76 * To anchor a popup to a node, supply an anchor node and set the position
77 * to a string indicating the manner in which the popup should be anchored.
78 * Possible values for position are:
79 * before_start, before_end, after_start, after_end,
80 * start_before, start_after, end_before, end_after,
81 * overlap, after_pointer
83 * The anchor node does not need to be in the same document as the popup.
85 * If the attributesOverride argument is true, the popupanchor, popupalign
86 * and position attributes on the popup node override the position value
87 * argument. If attributesOverride is false, the attributes are only used
88 * if position is empty.
90 * For an anchored popup, the x and y arguments may be used to offset the
91 * popup from its anchored position by some distance, measured in CSS pixels.
92 * x increases to the right and y increases down. Negative values may also
93 * be used to move to the left and upwards respectively.
95 * Unanchored popups may be created by supplying null as the anchor node.
96 * An unanchored popup appears at the position specified by x and y,
97 * relative to the viewport of the document containing the popup node. In
98 * this case, position and attributesOverride are ignored.
100 * @param anchorElement the node to anchor the popup to, may be null
101 * @param position manner is which to anchor the popup to node
102 * @param x horizontal offset
103 * @param y vertical offset
104 * @param isContextMenu true for context menus, false for other popups
105 * @param attributesOverride true if popup node attributes override position
106 * @param triggerEvent the event that triggered this popup (mouse click for example)

117 * Open the popup at a specific screen position specified by x and y. This
118 * position may be adjusted if it would cause the popup to be off of the
119 * screen. The x and y coordinates are measured in CSS pixels, and like all
120 * screen coordinates, are given relative to the top left of the primary
