delphi - Techart 中的线笔、线刷和楼梯

Question

我正在尝试使用线笔、线刷和楼梯，但在 Delphi 2007 中我在它们下面得到了一条红色波浪线。我想我忘了添加一个单元。我应该包括哪个单元。

我正在尝试从 teeoffice 演示复制 popupline 代码。谢谢。磷

Answer 1

The LinePen,LineBrush and Stairs are properties of TCustomSeries and descendants. They are defined in unit Series.

Just a comment on the red wavy lines (aka Error Insight). At times Error Insight is known to give false positives. It's better in more modern Delphi versions. Sometimes storing the project files, reopening the project or rebuilding the project makes those false positives vanish.
