NSTableView命令选项卡在编辑时从行跳到行 [英] NSTableView hit tab to jump from row to row while editing

问题描述

我有一个NSTableView。编辑时，如果我打标签页，它会自动跳转到下一列。这是太棒了，但是当我在编辑最后一列中的字段时，我打标签，我想要焦点跳到NEXT行的第一列。

I've got an NSTableView. While editing, if I hit tab it automatically jumps me to the next column. This is fantastic, but when I'm editing the field in the last column and I hit tab, I'd like focus to jump to the first column of the NEXT row.

任何建议？

感谢Michael为起始代码，这是非常接近，结束了工作！这里是我使用的最终代码，希望它将有助于别人：

Thanks to Michael for the starting code, it was very close to what ended up working! Here is the final code that I used, hope it will be helpful to someone else:

- (void) textDidEndEditing: (NSNotification *) notification {
    NSInteger editedColumn = [self editedColumn];
    NSInteger editedRow = [self editedRow];
    NSInteger lastColumn = [[self tableColumns] count] - 1;

    NSDictionary *userInfo = [notification userInfo];

    int textMovement = [[userInfo valueForKey:@"NSTextMovement"] intValue];

    [super textDidEndEditing: notification];

    if ( (editedColumn == lastColumn)
        && (textMovement == NSTabTextMovement)
        && editedRow < ([self numberOfRows] - 1)
        )
    {
        // the tab key was hit while in the last column, 
        // so go to the left most cell in the next row
        [self selectRowIndexes:[NSIndexSet indexSetWithIndex:(editedRow+1)] byExtendingSelection:NO];
        [self editColumn: 0 row: (editedRow + 1)  withEvent: nil select: YES];
    }

}

推荐答案

子类UITableView并添加代码来捕获textDidEndEditing调用。

Subclass UITableView and add code to catch the textDidEndEditing call.

然后，您可以根据以下内容决定要执行的操作：

You can then decide what to do based on something like this:

- (void) textDidEndEditing: (NSNotification *) notification
{
    NSDictionary *userInfo = [notification userInfo];

    int textMovement = [[userInfo valueForKey:@"NSTextMovement"] intValue];

    if ([self selectedColumn] == ([[self tableColumns] count] - 1))
        (textMovement == NSTabTextMovement)
    {
        // the tab key was hit while in the last column, 
        // so go to the left most cell in the next row
        [yourTableView editColumn: 0 row: ([self selectedRow] + 1)  withEvent: nil select: YES];
    }

    [super textDidEndEditing: notification];
    [[self window] makeFirstResponder:self];

} // textDidEndEditing

此代码未经测试...没有保证...等等。你可能需要移动[超级textDidEndEditing：]调用最右边选项卡单元格的情况。但希望这将帮助你到终点线。让我知道！

This code isn't tested... no warranties... etc. And you might need to move that [super textDidEndEditing:] call for the tab-in-the-right-most-cell case. But hopefully this will help you to the finish line. Let me know!
