virtual void nsIContent::BeginAddingChildren ( ) [inline, virtual, inherited]

nsresult nsSVGElement::BindToTree ( nsIDocument aDocument,
nsIContent aParent,
nsIContent aBindingParent,
PRBool  aCompileEventHandlers 
) [virtual, inherited]

Bind this content node to a tree.

If this method throws, the caller must call UnbindFromTree() on the node. In the typical case of a node being appended to a parent, this will be called after the node has been added to the parent's child list and before nsIDocumentObserver notifications for the addition are dispatched.

Parameters:
aDocumentThe new document for the content node. Must match the current document of aParent, if aParent is not null. May not be null if aParent is null.
aParentThe new parent for the content node. May be null if the node is being bound as a direct child of the document.
aBindingParentThe new binding parent for the content node. This is allowed to be null. In that case, the binding parent of aParent, if any, will be used.
aCompileEventHandlerswhether to initialize the event handlers in the document (used by nsXULElement)
Note:
either aDocument or aParent must be non-null. If both are null, this method will crash.
This method must not be called by consumers of nsIContent on a node that is already bound to a tree. Call UnbindFromTree first.
This method will handle rebinding descendants appropriately (eg changing their binding parent as needed).
This method does not add the content node to aParent's child list

This method is called when the parser finishes creating the element's children, if any are present.

NOTE: this is currently only called for textarea, select, applet, and object elements in the HTML content sink. If you want to call it on your element, modify the content sink of your choice to do so. This is an efficiency measure.

If you also need to determine whether the parser is the one creating your element (through createElement() or cloneNode() generally) then add a boolean aFromParser to the NS_NewXXX() constructor for your element and have the parser pass true. See nsHTMLInputElement.cpp and nsHTMLContentSink::MakeContentObject().

Here is the caller graph for this function:

virtual void nsIContent::DoneCreatingElement ( ) [inline, virtual, inherited]

This method is called when the parser finishes creating the element.

This particularly means that it has done everything you would expect it to have done after it encounters the > at the end of the tag (for HTML or XML). This includes setting the attributes, setting the document / form, and placing the element into the tree at its proper place.

For container elements, this is called before any of the children are created or added into the tree.

NOTE: this is currently only called for input and button, in the HTML content sink. If you want to call it on your element, modify the content sink of your choice to do so. This is an efficiency measure.

If you also need to determine whether the parser is the one creating your element (through createElement() or cloneNode() generally) then add a boolean aFromParser to the NS_NewXXX() constructor for your element and have the parser pass true. See nsHTMLInputElement.cpp and nsHTMLContentSink::MakeContentObject().

DO NOT USE THIS METHOD to get around the fact that it's hard to deal with attributes dynamically. If you make attributes affect your element from this method, it will only happen on initialization and JavaScript will not be able to create elements (which requires them to first create the element and then call setAttribute() directly, at which point DoneCreatingElement() has already been called and is out of the picture).

During the Mark phase of the GC, we need to mark all of the preserved wrappers that are reachable via DOM APIs.

Since reachability for DOM nodes is symmetric, if one DOM node is reachable from another via DOM APIs, then they are in the same strongly connected component. (Strongly connected components are never reachable from each other via DOM APIs.) We can refer to each strongly connected component by walking up to the top of the parent chain. This function finds that root node for any DOM node.

nsresult nsGenericElement::HandleDOMEvent ( nsPresContext aPresContext,
nsEvent aEvent,
nsIDOMEvent **  aDOMEvent,
PRUint32  aFlags,
nsEventStatus aEventStatus 
) [virtual, inherited]

Handle a DOM event for this piece of content.

This method is responsible for handling and controlling all three stages of events, capture, local and bubble. It also does strange things to anonymous content which whiz right by this author's head.

Here are some beginning explanations:

  • if in INIT or CAPTURE mode, it must pass the event to its parent in CAPTURE mode (this happens before the event is fired, therefore the firing of events will occur from the root up to the target).
  • The event is fired to listeners.
  • If in INIT or BUBBLE mode, it passes the event to its parent in BUBBLE mode. This means that the events will be fired up the chain starting from the target to the ancestor.

NOTE: if you are extending nsGenericElement and have to do a default action, call super::HandleDOMEvent() first and check for aEventStatus != nsEventStatus_eIgnore and make sure you are not in CAPTURE mode before proceeding.

XXX Go comment that method, Will Robinson.

Parameters:
aPresContextthe current presentation context
aEventthe event that is being propagated
aDOMEventa special event that may contain a modified target. Pass in null here or aDOMEvent if you are in HandleDOMEvent already; don't worry your pretty little head about it.
aFlagsflags that describe what mode we are in. Generally NS_EVENT_FLAG_CAPTURE, NS_EVENT_FLAG_BUBBLE and NS_EVENT_FLAG_INIT are the ones that matter.
aEventStatusthe status returned from the function. Generally nsEventStatus_eIgnore

virtual PRBool nsIContent::IsFocusable ( PRInt32 aTabIndex = nsnull) [inline, virtual, inherited]

Check if this content is focusable and in the current tab order.

Note: most callers should use nsIFrame::IsFocusable() instead as it checks visibility and other layout factors as well. Tabbable is indicated by a nonnegative tabindex & is a subset of focusable. For example, only the selected radio button in a group is in the tab order, unless the radio group has no selection in which case all of the visible, non-disabled radio buttons in the group are in the tab order. On the other hand, all of the visible, non-disabled radio buttons are always focusable via clicking or script. Also, depending on either the accessibility.tabfocus pref or a system setting (nowadays: Full keyboard access, mac only) some widgets may be focusable but removed from the tab order.

Parameters:
[inout,optional]aTabIndex the computed tab index In: default tabindex for element (-1 nonfocusable, == 0 focusable) Out: computed tabindex
[optional]aTabIndex the computed tab index < 0 if not tabbable == 0 if in normal tab order > 0 can be tabbed to in the order specified by this value
Returns:
whether the content is focusable via mouse, kbd or script.
