Re: Re: How to set focus on editable table view cell on Enter key press

Hi,I am able to set the focus on editable cell using selectRowIndexes:byExtendingSelection: and editColumn:row:withEvent:select:. I have a"addRow" method. I have written this code at the end of addRow method so that when ever new row is added the editable cell of new row get selected.I call addRow method after accepting the user input in (void)tableView:(NSTableView *)pTableView setObjectValue:(id)object forTableColumn:(NSTableColumn *)pTableColumn row:(int)pRowIndex mehtod on Enter key press. This is how it looks.(int)addRow{........ NSIndexSet *iset = [NSIndexSet indexSetWithIndex:(NSUInteger)itemnum]; [wltable selectRowIndexes:iset byExtendingSelection:NO]; [wltable editColumn:(NSInteger)1 row:(NSInteger)itemnum withEvent:nil select:NO];} (void)tableView:(NSTableView *)pTableView setObjectValue:(id)object forTableColumn:(NSTableColumn *)pTableColumn row:(int)pRowIndex {........[self addRow];}It works fine if user enters some text in the table view cell and presses Enter ke
 y. But if user does not enter anything and just hit Enter key a new row is not added because tableView:setObjectValue:forTableColumn:row: mehtod is not invoked. So I removed the addRow call from tableView:setObjectValue:forTableColumn:row: and call it from NSControlTextDidEndEditingNotification. Something like this (void)cellTextDidEndEditing:(NSNotification *)notif{ [self addRow]; }It adds a new row on Enter button click but now the editable cell of new row is not selected by default and the row color is also grey (is that mean that the focus is somewhere else?). How to fix this?

I can do it by putting a button on screen and connecting it with Delete key but i don't want to use a button on my screen.Any help will be appreciated.Thanks & RegardsAbhijeetGet Yourself a cool, short @in.com Email ID now!For Delete, you need to implement delete:, because that method is by default connected to the Delete key in the Edit menu. You implement that either in your window controller subclass,
  or in a tableview subclass, or both, depending on whether you want to have the delete key work everywhere or only when the tableview is focused. I have NSTableView subclasses that implement delete: (and some other actions) going through custom delegate methods: (BOOL)canDelete {NSIndexSet *indexes = [self selectedRowIndexes];if ([indexes count] && [[self delegate] respondsToSelector:@selector(tableView:deleteRowsWithIndexes:)]) {if ([[self delegate] respondsToSelector:@selector(tableView:canDeleteRowsWithIndexes:)])return [[self delegate] tableView:self canDeleteRowsWithIndexes:indexes];elsereturn YES;}return NO;} (void)delete:(id)sender {if ([self canDelete])[[self delegate] tableView:self deleteRowsWithIndexes:[self selectedRowIndexes]];elseNSBeep();}ChristiaanGet Yourself a cool, short @in.com Email ID now!
