关于TCnTrayIcon和TCnRS232
TCnTrayIcon和TCnRS232应该增加一个Boolean的属性,以指示当前组件状态
如:
TCnTrayIcon增加Showing 为True时程序是显示状态,为False时程序为隐藏状态
TCnRS232增加Connection 为True时端口在打开状态,为False时端口在关闭状态

多谢建议!
这两个属性确实应该具备。CnRS232 已经增加了一个运行期只读属性 Connected,CnTrayIcon 已经通知作者进行更新。
更新过的组件您可以在下一版本发布时找到,或者从 CVS 中取得。

您说的Showing属性是指什么功能?
如果是图标是否显示,Active属性应该可以做到吧。
如果是CnTrayIcon所属的窗体是否显示,似乎不是CnTrayIcon所管的范围?

但如果你要做一个“显示/隐藏主窗口”的功能,不知道程序或主窗口是否在隐藏状态,功能该怎么做?

试过了,不行,隐藏后就不可以打开了。
代码如下,你可以试试:
if not Form1.Visible then
CnTrayIcon1.ShowApplication
else
CnTrayIcon1.HideApplication;

您说的没错,俩状态是不一致
俩状态不一致,不过应该将状态统一起来,无需加其他属性了。
上面代码无效的情况,实际上可以算是CnTrayIcon的一个bug吧。
我们已经修正这个问题了。
