Fw: [PHP-GTK] twice-echoed returns

["Steph" <Steph Fox btinternet com>]

Last appeal to the GTK+ list on this issue I promise ...

In PHP-GTK compound widgets appear to be sending signals twice over for no good reason.  Is this feature familiar to GTK+ users in any other form?

Actually thinking about it it's probable that the function does run twice.  It'll be redrawing, effectively, where I've used it and it appears to only run once.

So it's a case of being a bit careful with coding where redrawing isn't an option, I guess.  Til there's more time for you to investigate it, anyways (or til GTK 2's stable release turns up and it isn't there any more, whatever).

I'll make a note of it on hitchhiker where I know it occurs, I think; that way nobody gets confused.

Can somebody please confirm that this isn't only in win32? - code for test is at the bottom of this mail's history.

Doesn't affect most calls (echoes twice, but if you're running a function from the signal that function will only run once).  

Shall I just add it to the Mysteries file?

Gee, I don't know, I didn't get any reply from the list. Short of
tracing through the gtk+ code with a debugger, I don't know what to do.
