RE: [platform-swt-dev] ActiveX fire event fails in multithreading mode (with AfxBeginThread)
|
So, you are saying that when I create an ActiveX control in my java
plug-in:
- Only the main thread of the ActiveX control is able to fire an event
which the java plug-in will catch?
- What if I create another thread from the main thread of the ActiveX
control and this another thread will fire an event?
I could not catch that event in my java plug-in?
Thanks,
Andras Lang
