是的，点击事件存储在消息队列中，并在上一个事件处理完毕后立即处理。

是否忽略按钮
点击如果waitcursor是活动的，但是如果默认光标处于活动状态则没有？

行为不依赖于游标，但是你应该设置游标

取决于应用程序/窗口状态。

按钮点击将排队。

如果
等待标记处于活动状态，它是否忽略按钮单击但是如果默认光标处于活动状态则忽略？

如何激活此光标？

If the user clicks the processit button, the click event code runs. What
happens if he/she clicks it again before it''s done processing? Does the
system remember and process twice? Does it ignore a button click if the
waitcursor is active but not if the default cursor is active?

OK - I apologize - 2 questions.

Tx,

Bernie

Yes, the click event is stored in the message queue and processed as soon as
the previous event(s) has been processed.

The behavior does not depend on the cursor, but you should set the cursor
depending on the application/window state.

The button click will be queued.
Does it ignore a button click if the
waitcursor is active but not if the default cursor is active?

How do you activate this cursor?
