Rahnah,
This happens because PowerPlant gets first chance at all the events
that occur and it doesn't know what to do with events for windows that
are not "PowerPlant" windows.
The drop-down menus in Mozilla are implemented on the Mac by creating a
temporary window to contain the menu items. This window is created with
a toolbox call rather than a call back into PowerPlant's
LWindow::CreateWindow(). Therefore, PowerPlant doesn't know what to do
when it gets an event for these windows, so it just ignores the event.
Though it's certainly not the cleanest solution, the work-around I've
used is to override the following LEventDispatcher routines in
CBrowserApp.cpp
EventUpdate
AdjustCursor
EventActivate
EventMouseUp
EventMouseDown
In each of these routines, I've added appropriate code to check if the
window the event occurred for is not a PowerPlant window. If it is not
then I check to see if it's a Mozilla window by using the
IsRaptorWindow routine found in nsMacMessageSink.
If it's a Mozilla window, I manually pass it into the
nsMacMessageSink::DispatchEvent routine. To accomplish this, I've had
to make mMessageSink in CBrowserShell a public member temporarily.
This is not a great solution, but it works.
In addition, in CBrowserApp.cpp, I've added a member variable to keep
track of the last Mozilla window clicked. This is to handle clicks
outside the "menu" windows. Without this handling, clicking outside the
"menu" results in the CBrowserWindow being brought in front of the
modal "Menu" window. Unless you move the window, you probably wouldn't
notice.
I've enclosed my copy of CBrowserApp.cpp. Hope it helps.
