Re: ruby-qt bindings - is somebody in charge of those?

From: Andrea Dallera <andrea@...>
Date: 2010-05-21 10:56:16 UTC
List: ruby-talk #363141
Hei Jan,

        I am using the version that comes with ubuntu - that's why I
didn't
really bother about versions. I will try to install the gem via rubygems
for windows.

I tried again, removing and reinstalling the packages with synaptic, and
I still get the same segfaults. It is hard for me to provide you with
exact examples that cause the issue, since I myself do not understand
what exactly causes them and the code that generates the segfaults is
built over the GUI framework. A very simple one would be to create a
Qt::CalendarWidget and sending selectedDate=, nil to it, like this:

require 'rubygems'
require 'Qt4'

app = Qt::Application.new([])
hello = Qt::CalendarWidget.new()
hello.resize(200,200)
hello.show()
hello.selectedDate = nil #[BUG] Segmentation fault ruby 1.8.7
(2010-01-10 patchlevel 249) [i486-linux]

Again, this is just a trivial example and it's very easy to write a
workaround for it: more nasty stuff happens when trying to add/remove
items for a ListWidget for example. I will try to build a test case for
that too.
