Here is the old log from nsISelection (since CVS doesn't allow renames): > revision 1.9 > date: 1999/02/02 00:23:35; author: mjudge%netscape.com; state: Exp; lines: +2 -1 > keyboard navigation of selection. adding API for nsIFrame. fixing nsFrame and nstextframe to reflect the implementations of the nsIFrame API. nsRangeList implements the handlekeyevent now. > ---------------------------- > revision 1.8 > date: 1999/01/29 18:57:51; author: akkana%netscape.com; state: Exp; lines: +6 -0 > Implement a new interface, nsIDOMSelection, intended to become the > external interface for selection (to be IDL-ified later). > > Fix some editor bugs: > - Advance the cursor on text insert (so text is inserted in the right order) > - Make DeleteSelection in the editor call the actual selection > - Make DeleteSelection update the frames' notion of the selection > ---------------------------- > revision 1.7 > date: 1999/01/25 01:42:32; author: mjudge%netscape.com; state: Exp; lines: +3 -4 > Focus tracker needs to send the tracker to the implementation of selection so that it can update the tracker as to which frame(s) should be considered the focus frames ect. This is not yet working fully. Everything I am checking in will stay, I simply have a decision to make as to exactly what to do next. RangeList also had some modifications to better selection > ---------------------------- > revision 1.6 > date: 1999/01/22 18:58:09; author: mjudge%netscape.com; state: Exp; lines: +6 -0 > chagnes for selection to work > ---------------------------- > revision 1.5 > date: 1999/01/18 22:57:08; author: mjudge%netscape.com; state: Exp; lines: +1 -1 > Files for selection across frames. > ---------------------------- > revision 1.4 > date: 1998/12/14 18:34:09; author: mjudge%netscape.com; state: Exp; lines: +13 -1 > adding in selection > ---------------------------- > revision 1.3 > date: 1998/12/08 18:25:37; author: mjudge%netscape.com; state: Exp; lines: +9 -32 > changes to selection > ---------------------------- > revision 1.2 > date: 1998/05/01 05:55:11; author: rpotts; state: Exp; lines: +1 -1 > nslayout.h is *all* lower case > ---------------------------- > revision 1.1 > date: 1998/04/30 19:15:05; author: rods; state: Exp; > initial
