Delphi：一个表单可以自由释放吗？ [英] Delphi: Is it ok for a form to free it self?

问题描述

我有一个表单，我用来显示一些信息几秒钟。该表格可以自由吗？我可以在构造函数中启动一个计时器，然后在timer-event中调用self.free吗？或者这可能会导致麻烦吗？

解决方案

此外，使用表单，您可以调用释放。

它向表单发送一个CM_RELEASE消息。作为一个反应，它称为免费。
发布的优点是没有任何消息可以导致崩溃。

I have a form that I use to show some information for some seconds. Is it ok for the form to free itself? Can I start a timer in the constructor, and then call self.free in the timer-event? Or will this potentially lead to trouble?

解决方案

In addition, with a form you can call release.

It sends a CM_RELEASE message to the form. As a reaction it calls Free. The advantage of release is that there are no messages left for the form which could result in a crash.
