Member Function Documentation

virtual nsresult nsSVGGlyphFrame::QueryInterface (  const nsIID &  aIID, void **  aInstancePtr )  [virtual]

Reimplemented from nsFrame.

virtual nsrefcnt nsSVGGlyphFrame::AddRef (  void   )  [inline, virtual]

Reimplemented from nsFrame. Definition at line 76 of file nsSVGGlyphFrame.cpp.

virtual nsrefcnt nsSVGGlyphFrame::Release (  void   )  [inline, virtual]

Reimplemented from nsFrame. Definition at line 77 of file nsSVGGlyphFrame.cpp.

virtual nsresult nsSVGGlyphFrame::Init (  nsIPresContext *  aPresContext, nsIContent *  aContent, nsIFrame *  aParent, nsStyleContext *  aContext, nsIFrame *  aPrevInFlow )  [virtual]

Called to initialize the frame. This is called immediately after creating the frame. If the frame is a continuing frame, then aPrevInFlow indicates the previous frame (the frame that was split). You should connect the continuing frame to its prev-in-flow, e.g. by using the AppendToFlow() function If you want a view associated with your frame, you should create the view now. Parameters: aContent  the content object associated with the frame aGeometricParent  the geometric parent frame aContentParent  the content parent frame aContext  the style context associated with the frame aPrevInFlow  the prev-in-flow frame See also: #AppendToFlow() Reimplemented from nsFrame.

virtual nsresult nsSVGGlyphFrame::ContentChanged (  nsIPresContext *  aPresContext, nsIContent *  aChild, nsISupports *  aSubContent )  [virtual]

This call is invoked when content is changed in the content tree. The first frame that maps that content is asked to deal with the change by generating an incremental reflow command. Parameters: aPresContext  the presentation context aContent  the content node that was changed aSubContent  a hint to the frame about the change Reimplemented from nsFrame.

virtual nsresult nsSVGGlyphFrame::SetSelected (  nsIPresContext *  aPresContext, nsIDOMRange *  aRange, PRBool  aSelected, nsSpread  aSpread )  [virtual]

Called to set the selection of the frame based on frame offsets. you can FORCE the frame to redraw event if aSelected == the frame selection with the last parameter. data in struct may be changed when passed in. Parameters: aRange  is the range that will dictate if the frames need to be redrawn null means the whole content needs to be redrawn aSelected  is it selected? aSpread  should it spread the selection to flow elements around it? or go down to its children? Reimplemented from nsFrame.

virtual nsresult nsSVGGlyphFrame::GetSelected (  PRBool *  aSelected  )  const [virtual]
