I'm having a problem with concurrent callbacks being generated.
Say that there are two buttons on the screen, each of which take a few moments
to process. If the user presses button A, and starts the process, and then
presses button B before A's callback is done, then both callbacks
are "running at the same time".
This has resulted in some inconsistent states and program crashes. (EG: the
callback for button A assumes that a certain object is defined, but since
button B was pressed before A was done, that object is no longer there)
Is this making sense? What's the best way to structure things to deal with
this issue?
As a side note, I have a function called "UpdateScreen()" that I use within
these intensive-processing functions as follows, so that the program "appears
responsive"... is this the problem?
Function UpdateScreen()
{
while (gtk::events_pending())
gtk::main_iteration();
}
