Hi there

i’ve been using fxruby 1.4 and it’s very good. one wrinkle though is  
i’m trying to get an event back from a table after i’ve entered data  
into a cell and don’t find any events that do the job by perusing the  
fxruby 1.4 docs.

however, the Fox1.4 class reference mentions a SEL\_REPLACE event, and  
indeed it seems i can use this in fxruby

@table.connect(SEL\_REPLACED) {|sender, selector, data|  
puts “got replacement”  
}

this seems to work, i.e. my message is printed, but it does generate  
the following assertion from fox

FXRuby.cpp:793: FXASSERT(FALSE) failed.

so the question is, is this event safe to use on a regular basis - if  
not how do i find out a data entry has been entered.

thanks

BD

I see that too, but can’t answer your question. You might want to ask it  
on the fxruby list.

I filed a bug report on your behalf at the project page (see  
[http://rubyforge.org/tracker/?atid=1223&group\_id=300&func=browse](http://rubyforge.org/tracker/?atid=1223&group_id=300&func=browse)).  
This bug will be fixed in the next release of FXRuby.

quick followup to anyone interested, the SEL\_REPLACED event works on  
Linux, with the assert printed, but crashes a windows application.
