| 21 | // A TXMsgBox is a specialised pop-up dialog window, designed to present |
| 22 | // the user with a small amount of textual information, and potentially to |
| 23 | // obtain their response. |
| 24 | // TXMsgBoxes are always modal, and may have an Ok button, Ok+Cancel buttons, |
| 25 | // or Yes+No buttons. |
| 26 | // The MsgBox helper function creates a TXMsgBox on the fly, runs it, and |
| 27 | // returns the result. |
