|
|
* Handle a window.open call from an out-of-process <iframe mozbrowser>.
|
|
*
|
|
* window.open inside <iframe mozbrowser> doesn't actually open a new
|
|
* top-level window. Instead, the "embedder" (the document which contains
|
|
* the <iframe mozbrowser> whose content called window.open) gets the
|
|
* opportunity to place a new <iframe mozbrowser> in the DOM somewhere. This
|
|
* new "popup" iframe acts as the opened window.
|
|
*
|
|
* This method proceeds in three steps.
|
|
*
|
|
* 1) We fire a mozbrowseropenwindow CustomEvent on the opener
|
|
* iframe element. This event's detail is an instance of
|
|
* nsIOpenWindowEventDetail.
|
|
*
|
|
* 2) The embedder (the document which contains the opener iframe) can accept
|
|
* the window.open request by inserting event.detail.frameElement (an iframe
|
|
* element) into the DOM somewhere.
|
|
*
|
|
* 3) If the embedder accepted the window.open request, we return true and
|
|
* set aPopupTabParent's frame element to event.detail.frameElement.
|
|
* Otherwise, we return false.
|
|
*
|
|
* @param aURL the URL the new window should load. The empty string is
|
|
* allowed.
|
|
* @param aOpenerTabParent the TabParent whose TabChild called window.open.
|
|
* @param aPopupTabParent the TabParent inside which the opened window will
|
|
* live.
|
|
* @return true on success, false otherwise. Failure is not (necessarily)
|
|
* an error; it may indicate that the embedder simply rejected the
|
|
* window.open request.
