Question

我想用右箭头和左箭头模拟标签和shift-tab。我假设我必须继承NSTableview并覆盖keydown代码，但我不知道如何告诉必须编辑列和行中的单元格的表视图。这是我有多远

-(void)keyDown:(NSEvent*)event{
    [super keyDown:event];
    NSLog(@"%hi", [event keyCode]);

        if ([event keyCode] == 48 && ([event modifierFlags] &
                                  NSShiftKeyMask)){
        [[self window] selectKeyViewPrecedingView:self];
    }

    if ([event keyCode] == 51){
        [[self window] selectKeyViewPrecedingView:self];

    }
    if ([event keyCode] == 124){
        if ([self selectedColumn] < [self numberOfColumns]-1) {

            [self performClickOnCellAtColumn:[self selectedColumn]+1 row:[self selectedRow]];
        }


    }
    if ([event keyCode] == 124){
        if ([self selectedColumn] > 0) {
            [self performClickOnCellAtColumn:[self selectedColumn]-1 row:[self selectedRow]];
        }


    }

}

Answer 1

-[NSTableView editColumn:row:withEvent:select:]

Answer 2

优于keydown，您可以从NSTableView覆盖NSControl委托：

- (BOOL)control:(NSControl *)control textView:(NSTextView *)textView doCommandBySelector:(SEL)command

在NSTableView中使用箭头键模拟Tab和Shift-Tab
