Invokes the WillReflow() function, positions the frame and its view (if requested), and then calls Reflow(). If the reflow succeeds and the child frame is complete, deletes any next-in-flows using DeleteNextInFlowChild()

Flags: NS_FRAME_NO_MOVE_VIEW - don't position the frame's view. Set this if you don't want to automatically sync the frame and view NS_FRAME_NO_MOVE_VIEW - don't move the frame. aX and aY are ignored in this case. Also implies NS_FRAME_NO_MOVE_VIEW

)  [static]
 

The second half of frame reflow. Does the following:

  • sets the frame's bounds
  • sizes and positions (if requested) the frame's view. If the frame's final position differs from the current position and the frame itself does not have a view, then any child frames with views are positioned so they stay in sync
  • sets the view's visibility, opacity, content transparency, and clip
  • invoked the DidReflow() function

Flags: NS_FRAME_NO_MOVE_FRAME - don't move the frame. aX and aY are ignored in this case. Also implies NS_FRAME_NO_MOVE_VIEW NS_FRAME_NO_MOVE_VIEW - don't position the frame's view. Set this if you don't want to automatically sync the frame and view NS_FRAME_NO_SIZE_VIEW - don't size the frame's view

nsIFrame* nsContainerFrame::GetOverflowFrames (  nsIPresContext *  aPresContext,
PRBool  aRemoveProperty
)  const [protected]
 

Get the frames on the overflow list

nsresult nsContainerFrame::SetOverflowFrames (  nsIPresContext *  aPresContext,
nsIFrame *  aOverflowFrames
)  [protected]
 

Set the overflow list

PRBool nsContainerFrame::MoveOverflowToChildList (  nsIPresContext *  aPresContext  )  [protected]
 

Moves any frames on both the prev-in-flow's overflow list and the receiver's overflow to the receiver's child list.

Resets the overlist pointers to nsnull, and updates the receiver's child count and content mapping.

Returns:
PR_TRUE if any frames were moved and PR_FALSE otherwise

void nsContainerFrame::PushChildren (  nsIPresContext *  aPresContext,
nsIFrame *  aFromChild,
nsIFrame *  aPrevSibling
)  [protected]
 

Push aFromChild and its next siblings to the next-in-flow. Change the geometric parent of each frame that's pushed. If there is no next-in-flow the frames are placed on the overflow list (and the geometric parent is left unchanged).

Updates the next-in-flow's child count. Does not update the pusher's child count.

Parameters:
aFromChild the first child frame to push. It is disconnected from aPrevSibling
aPrevSibling aFromChild's previous sibling. Must not be null. It's an error to push a parent's first child frame
