So now I'm getting osEvt, mouseDown, and updateEvt, but no activateEvt, and so
the mouseDown only tries to activate each time. I can probably workaround that
by accepting the first click.
Adding a Carbon window event handler seems to be the way. I added a handler for
kEventClassWindow/kEventWindowActivated and
kEventClassWindow/kEventWindowDeactivated
Through that I am getting activate events. So I no longer have to accept
activate clicks to get mouseDowns. And the whole need for calling the Carbon
event handling from a Cocoa timer went away, and with it the dropped mouse ups.
...Yes, doing that yields an app that is closer to working than what I've seen
yet. Mouse ups are sometimes being dropped though. And while Carbon portions
are working much better, Cocoa windows are now non-interactive, no longer
getting any clicks, and with the close/minimize/zoom buttons dimmed.
But with activateEvt being the culprit, maybe I'm in the normal territory for
Carbon+Cocoa scenario?
But do you think there is something better I can do than call the Carbon event
handler on a timer?
Taken care of by the above.
Cocoa mouseDowns were still being eaten. Then I discovered that without
realizing it, invocation of my Carbon event loop was part of the code I had
added to applicationDidFinishLaunching in trying to "clean up" my Carbon/Cocoa
hybrid situation. So there was no Cocoa event loop running, and the mouseDown
part of my Carbon handler was of the classic polling (via ReceiveNextEvent)
variety, which provides no way to filter for events that are Carbon-window only.
Thus the Cocoa mouseDowns were getting absorbed, with no practical way (that I
found) to re-dispatch them to the Cocoa windows.
Regardless, presumably if I flesh out the Window event handlers on the Carbon
side I will see my way through the remaining problems. I'll report back after I
work through that.
