RE: [platform-swt-dev] ActiveX fire event fails in multithreading mode (with AfxBeginThread)
|
SWT only supports the apartment threaded model. You must create your
activeX control in the UI thread and perform any tasks on it from the UI
thread.
SWT uses OleCreate to create the activeX control.

Please respond to
platform-swt-dev
Maybe I don't get this, but syncExec() and asyncExec() is used for
invoking a method from a non-UI thread...
But my (ActiveX) EventListener runs in the main UI thread:
layout.controlSite.addEventListener(1, new
OleListener()
{
public void handleEvent(OleEvent
event) {
Shell shell =
Layout.getShell();
MessageDialog.openInformation(shell,
"activex fired me", "activex fired me");
}
});
So I don't think this is the problem. If I am wrong, please correct me!
I tried the whole thing out in an MFC application and the application
could get the events
from the activeX component even if the event was fired in an afx thread
or even not.
