NSSearchField - 显示带有结果的 NSMenu

发布于 2024-11-05 11:26:00 字数 521 浏览 0 评论 0原文

我正在尝试弄清楚如何在搜索字段下方显示搜索结果。我想原因是我的程序从未收到消息

-(NSArray *)control:(NSControl *)control textView:(NSTextView *)textView completions:(NSArray *)words forPartialWordRange:(NSRange)charRange indexOfSelectedItem:(int*)index;

所以我永远无法返回任何结果。

但是，我确实收到

- (void)controlTextDidChange:(NSNotification *)obj;
- (BOOL)control:(NSControl *)control textView:(NSTextView *)textView doCommandBySelector:(SEL)commandSelector;

任何可能的原因是什么？我确实设置了代表。

I'm trying to figure out how to display results of search below my search field. I suppose the cause is that my program never receives the message

-(NSArray *)control:(NSControl *)control textView:(NSTextView *)textView completions:(NSArray *)words forPartialWordRange:(NSRange)charRange indexOfSelectedItem:(int*)index;

So I can never return any results.

However, I do receive

- (void)controlTextDidChange:(NSNotification *)obj;
- (BOOL)control:(NSControl *)control textView:(NSTextView *)textView doCommandBySelector:(SEL)commandSelector;

Any chances what the cause may be? I did set the delegate.

除非在文本字段的字段编辑器上的某个时刻调用 complete，否则您的委托将不会收到 completions: 消息。在 controlTextDidChange: 中，您可以执行以下操作：

- (void)controlTextDidChange:(NSNotification *)note {

    NSTextView * fieldEditor = [[note userInfo] objectForKey:@"NSFieldEditor];

    [fieldEditor complete];
}

毫无疑问，您必须使其变得更加复杂（当您的委托返回完成列表时，将调用 controlTextDidChange:再次，创建一个无限循环），但这应该可以帮助您开始。

Your delegate won't receive the completions: message unless complete gets called at some point on the field editor of the text field. In controlTextDidChange: you can do this:

- (void)controlTextDidChange:(NSNotification *)note {

    NSTextView * fieldEditor = [[note userInfo] objectForKey:@"NSFieldEditor];

    [fieldEditor complete];
}

You will, without a doubt, have to make this more sophisticated (when your delegate returns the list of completions, controlTextDidChange: will be called again, creating an infinite loop), but that should get you started.
