冻结向网格添加新行（wxwidgets）

Question

这是我使用wxWidgets的第一个项目，也许这是初学者的典型错误，但我找不到错误。该程序只是使用TeamSpeak SDK进行的聊天，因此非常简单。正如你可以访客，我有一个网格来显示消息但问题是有时我不能添加新行。程序完全冻结，即使在我调试时，也没有任何异常，在Visual Studio 2013上，callStack是完全空的，我无法理解为什么会发生这种情况，因为如果我在构造函数类中添加一行，那么行添加没有任何问题。

我正在做的是让程序适应MVC模式，因为该程序以前有效，但之前已经编过程序员，没有按照这种模式进行，但是它有效！

所以，这是标题GUI类，

我正在调试此程序时冻结程序：

gridchat-＆gt; AppendRows（1，true）; //添加新消息行

怎么可能？我该怎么解决？我使用的是exwidgets 2.9.3版本 非常感谢你的时间。

感谢您的时间。

鉴于错误行为，可能是对AppendRows的调用会触发再次调用updatePanelMsg（）的事件。因此，您将获得对函数的无限堆栈调用，从而打破调试器和程序。

如果是这种情况，您可以在ClientTsFrm中添加一个布尔标志，表示是否已经在堆栈上调用了updatePanelMsg。

在一个不相关的注释中，由于DECLARE EVENT TABLE宏，目前所有类的“私有”成员实际上都受到保护。
