Methods

clearHistoryEntry()

Clears the current history entry. This is used to clear out the saved presentation state.

void clearHistoryEntry();
Parameters

None.

close()

All users of a content viewer are responsible for calling both close() and destroy(), in that order.

close() should be called when the load of a new page for the next content viewer begins, and destroy() should be called when the next content viewer replaces this one.

Note: If the document is currently being printed, it will not be saved in session history.
void close(
  in nsISHEntry historyEntry
);
Parameters
historyEntry
The session history entry for the content viewer. If this is null, then destroy() will be called on the document by close(). If it is non-null, the document will not be destroyed, and the following actions will happen when destroy() is called:

destroy()

void destroy();
Parameters

None.

findContainerView()

Finds the view to use as the container view for MakeWindow.

Note: Prior to Gecko 10.0 (Firefox 10.0 / Thunderbird 10.0 / SeaMonkey 2.7), this attribute was part of nsIDocumentViewer.
[noscript,notxpcom,nostdcall] nsIViewPtr findContainerView();
Parameters

None.

Return value

The container view, or null if this content viewer is the root of a view manager hierarchy.

Note: If this container is the root of a view manager hierarchy (that is, this method returns null), and mParentWidget is also null, then this document should not even be displayed.

Native code only!

getBounds

void getBounds(
  in nsIntRectRef aBounds
);
Parameters
aBounds
Missing Description

getDocument()

Returns the DOM document object (as an nsIDocument without addrefing.

[noscript,notxpcom] nsIDocumentPtr getDocument();
Parameters

None.

Return value

The DOM document object.

hide()

void hide();
Parameters

None.

Native code only!

init

Initializes the content viewer.

void init(
  in nsIWidgetPtr aParentWidget,
  [const] in nsIntRectRef aBounds
);
Parameters
aParentWidget
Missing Description
aBounds
Missing Description

loadComplete()

void loadComplete(
  in unsigned long aStatus
);
Parameters

open()

Attaches the content viewer to its DOM window and docshell.

void open(
  in nsISupports aState,
  in nsISHEntry aSHEntry
);
Parameters
aState
A state object that might be useful in attaching the DOM window.
aSHEntry
The history entry that the content viewer was stored in. The entry must have the docshells for all of the child documents stored in its child shell list.

pageHide()

void pageHide(
  in boolean isUnload
);
Parameters
isUnload
Missing Description

Missing Description

permitUnload()

Determins whether or not the document wants to prevent unloading by firing beforeunload on the document, and if it does, prompts the user. The result is returned.

boolean permitUnload(
  in boolean aCallerClosesWindow Optional
);
Parameters
aCallerClosesWindow Optional
Indicates that the current caller will close() the window. If the method returns true, all subsequent calls will be ignored.
Return value

true if the document will allow unloading; otherwise false.

requestWindowClose()

boolean requestWindowClose();
Parameters

None.

Return value

resetCloseWindow()

Works in tandem with permitUnload(), if the caller decides not to close() the window it indicated it will, it is the caller's responsibility to reset that with this method.
