文档表不响应键盘事件 [英] Document sheet not responding to keyboard events

问题描述

我认为这是急救人员的问题，但我不确定.我正在为表格视图中的数据实现一个编辑窗口.在概念上与用于在Mail.app中编辑过滤器规则的UI非常相似.

I think it's a first responder problem, but I'm not sure. I'm implementing an edit window for data in a table view. Very similar in concept to the UI for editing filter rules in Mail.app.

我有一个编辑窗口，该窗口通过以下方式连接到主窗口:

I have an editing window that I attach to my primary window with:

[NSApp beginSheet: criteriaEditPanel 
   modalForWindow: [self window] 
    modalDelegate: self 
   didEndSelector: @selector(criteriaEditDidEnd:returnCode:contextInfo:) 
      contextInfo: (void *)[criteriaList objectAtIndex: index]];

从主窗口的标题栏中，面板正确显示.我可以使用鼠标来操纵面板上的弹出控件，但是我无法编辑文本字段，也无法在字段之间切换.其他一切都正常.有什么想法吗?

The panel displays properly, from the title bar of the main window. I can manipulate the pop-up controls on the panel with the mouse, but I can't edit the text fields and I can't tab between fields. Everything else works fine. Any ideas?

推荐答案

已解决.信不信由你，您必须为面板启用标题栏，即使将其显示为工作表也不可见.在IB中启用该功能后，键盘输入开始起作用.

Solved. Believe it or not, you have to have the Title Bar enabled for the panel, even though it's never visible when displayed as a Sheet. When enabled it in IB, keyboard input started working.
