nsIPopupBoxObject Interface

 If keyboard navigation is enabled, the keyboard may be used to navigate
 the menuitems on the popup. Enabling keyboard navigation is the default
 behaviour and will install capturing key event listeners on the popup
 that do not propagate key events to the contents. If you wish to place
 elements in a popup which accept key events, such as textboxes, keyboard
 navigation should be disabled.

 Setting ignorekeys="true" on the popup element also disables keyboard
 navigation, and is recommended over calling this method.

void enableKeyboardNavigator(in boolean enableKeyboardNavigator)

 
 Enable automatic popup dismissal. This only has effect when called
 on an open popup.

void enableRollup(in boolean enableRollup)

  Hide the popup if it is open.

void hidePopup()

 Move the popup to a point on screen in CSS pixels.

void moveTo(in long left, in long top)

 Open the popup relative to a specified node at a specific location.

 The popup may be either anchored to another node or opened freely.
 To anchor a popup to a node, supply an anchor node and set the position
 to a string indicating the manner in which the popup should be anchored.
 Possible values for position are:
    before_start, before_end, after_start, after_end,
    start_before, start_after, end_before, end_after,
    overlap, after_pointer

 The anchor node does not need to be in the same document as the popup.

 If the attributesOverride argument is true, the popupanchor, popupalign
 and position attributes on the popup node override the position value
 argument. If attributesOverride is false, the attributes are only used
 if position is empty.

 For an anchored popup, the x and y arguments may be used to offset the 
 popup from its anchored position by some distance, measured in CSS pixels.
 x increases to the right and y increases down. Negative values may also
 be used to move to the left and upwards respectively.

 Unanchored popups may be created by supplying null as the anchor node.
 An unanchored popup appears at the position specified by x and y,
 relative to the viewport of the document containing the popup node. In
 this case, position and attributesOverride are ignored.

 @param anchorElement the node to anchor the popup to, may be null
 @param position manner is which to anchor the popup to node
 @param x horizontal offset
 @param y vertical offset
 @param isContextMenu true for context menus, false for other popups
 @param attributesOverride true if popup node attributes override position

void openPopup(in nsIDOMElement anchorElement, in AString position, in long x, in long y, in boolean isContextMenu, in boolean attributesOverride)

 Open the popup at a specific screen position specified by x and y. This
 position may be adjusted if it would cause the popup to be off of the
 screen. The x and y coordinates are measured in CSS pixels. The monitor
 selected is determined within the platform specific widget code, but
 in general, the coordinates are relative to the screen the window
 containing the popup is on.

 @param isContextMenu true for context menus, false for other popups
 @param x horizontal screen position
 @param y vertical screen position

void openPopupAtScreen(in long x, in long y, in boolean isContextMenu)

  This method is deprecated. Use openPopup or openPopupAtScreen instead.

void showPopup(in nsIDOMElement srcContent, in nsIDOMElement popupContent, in long xpos, in long ypos, in wstring popupType, in wstring anchorAlignment, in wstring popupAlignment)

 
 Size the popup to the given dimensions

void sizeTo(in long width, in long height)
