Problem with PaintDC(MSW)
When implementing EVT_PAINT handlers in c++ the PaintDC object is
constructed at the beginning of the function,
and auto destructed at it''s end, which informs wxwidgets that "invalid
regions in the window have been repainted".
Under ruby, this is not the case and causes a stream of EVT_PAINT events
to be sent to the given window (until one
of PaintDC objects is destructed by

Converting rb_protect + ruby_stop to pure Ruby
Hi,
Within process.c, in the fork method, there''s this bit of code:
if(rb_block_given_p()){
int status;
rb_protect(rb_yield, Qundef, &status);
ruby_stop(status);
}
I translated that as this:
if block_given?
status = 0
begin
yield
rescue Exception
status = -1 # Any non-zero result is failure
end
exit(status)
end
Is there a way to get the actual status? The $? global isn'&...

Quick thought on win32-mmap
I suggest getting rid of the hash style arguments fior new() for this
package. In this particular case, you already have a class and accessors,
so you can just use the yield trick, e.g. rb_yield(self) if
rb_block_given_p(). Thus you can do:
mm = Mmap.new do |m|
m.namespace = file
m.swapfile = sfile
m.size = 1024
end
Looks just as nice, and is a lot less code on the C side of things. I only
use the hash-style keys when I don''t feel like creating separate objects, or...

wxSockets
Hello guys,
Alright Alex..... I need a few tips on where to start. I know that I''m
going to need to rewrite the wxSocket header files, in order to incorperate
them into wxRuby. But some advice on stuff such as
wxSocketClient::new/connect, where it takes a wxIPAddress, and so forth. I
know they are pretty friviolous structures for holding information about
Addresses in which to make

Background thread - entension code - switch contexts
Hi,
I am using wxRuby 1.9.7 and Ruby 1.8.6. I have built an extension in C++
and used swig to load it into Ruby interpreter, which works great. The
extension is an often long executing algorithm, and I''ve noticed that if
I fork a new Ruby thread in button clicked event, and in this thread run
the algorithm the application freezes for the time of execution. I have
looked through the
