Re: GTK+ redraw programs

[Mikael Hermansson <mikeh bahnhof se>]

Nope!

None of the patched worked (Owen and yours) :-/

But here is the log for you g_print patch.

I am using IceWM and have tried with both WindowMaker and E with same
results. Xfree version 3.3.1

The problem has come since the >= GTK 1.2.5 

As I see it the expose IS actually happen but the problem is that it looks 
like it draws only a tiny line (height = 1) and next time if i resize the
window all the childwidgets will show correct size...

Greats
