Re: More MAC questions

Julian:

Perhaps I am missing something here, like the definition of a predefined
control.

Is a wxFrame a predefined control? a wxBitmap?

What I have is a bitmap that I am presenting. It is tied to the real
world and my program knows this connection. When I click on a point I
want to have the program present information derived from tying the
mouse click point to the real world, and then getting the information
for that real world point.

I have no predefined control as I have mentally defined it.

Any thoughts or help?

Thanks,
Ralph Pass

Hi Ralph,

Sorry, I deduced wrongly that you were trying to intercept a button-up
from a wxButton control.

A wxBitmap is not a control, and wxFrame wasn't a control in the sense I
was meaning - something that presents a higher-level command event to
the application.

I can't think why there should be a problem getting a mouse up event if
you've defined a handler for it and an event table entry... but then
it's hard to say without seeing code.
