I am pretty certain that the event handler is right because I get all the
events in the event handler (frmOpenEvent, lots of nilEvents, etc). I get
the keyUpEvent and keyDownEvent in that event handler, but I don't get any
ctlSelectEvents. My impression is that the system event handler looks at
the active form on the keyUpEvent or keyDownEvent and sees if the hit is
inside a control. The system then generates the ctlSelectEvent and changes
colors of buttons, etc. My problem is that I'm not getting ctlSelectEvents.
I am guessing that it is either because the system doesn't recognize my
dynamically generated form or because the attribute bits 'enabled',
'usable', and 'visible' are not set for the form, window, or controls. And
I can't get those bits to change. I write 1 to them (despite the warning in
the docs that I should treat those as opaque), but they remain 0. I keep no
form pointers around. Everything is done with form pointers generated
immediately before they are needed.
My hair used to be monochrome, but now it has 4 gray-scales.
