[haiku-3rdparty-dev] Target of BMessage from BMessageQueue?

Hi all,
in the HaikuLauncher WebKit browser, I have code like this:
void WebProcess::skipToLastMessage(BMessage*& message)
{
bool first = true;
BMessageQueue* queue = Looper()->MessageQueue();
while (BMessage* nextMessage = queue->FindMessage(message->what)) {
if (!first)
delete message;
message = nextMessage;
queue->RemoveMessage(message);
first = false;
}
}
This is suppose to fast-forward to the last message of a kind from within
WebProcess::MessageReceived(). WebProcess is a BHandler attached to the
BApplication. If there are more than one web pages open, there will be one
WebProcess per page. And you can probably already see the problem. I am
stealing messages from the other processes, and worst case, I end up
processing a BMessage intended for another WebProcess. Is there any way to
detect the intended BHandler target of a BMessage when peaking into the
queue like that?
Best regards,
-Stephan
